In Adobe Acrobat Should You Compress Text and Line Art?

Adobe PDF selection categories

You can set PDF options when yous export to PDF or when yous create or edit PDF presets. Adobe PDF options are divided into categories. The categories are listed on the left side of the Export Adobe PDF dialog box, with the exception of the Standard and Compatibility options, which are at the top of the dialog box. When you're exporting to PDF, changing any of the options causes "modified" to appear at the end of the preset name.

Standard

Specifies a PDF/10 format for the file.

Compatibility

Specifies a PDF version for the file.

Full general

Specifies basic file options.

Compression

Specifies if artwork should be compressed and downsampled, and if then, which method and settings to use.

Marks and Bleeds

Specifies printer'south marks and the bleed and slug areas. Although the options are the same as in the Print dialog box, the calculations are subtly unlike because a PDF is not output to a known page size.

Output

Controls how colors and PDF/X output intent profiles are saved in the PDF file.

Advanced

Controls how fonts, OPI specifications, transparency flattening, and JDF instructions are saved in the PDF file.

Security

Adds security to the PDF file. Security options are not available when yous create or edit a PDF preset.

Summary

Displays a summary of the current PDF settings. You tin can click the pointer next to a category (for example, General) to view private settings. To save the summary as an ASCII text file, click Save Summary. A alarm icon appears with explanatory text if a setting in the selected preset cannot be honored and must be remapped. For example, if a preset specifies source profiles that don't match the current colour settings file, then the profiles specified past the color settings file will exist used.

Nigh PDF/10 standards

PDF/Ten standards are defined by the International System for Standardization (ISO). PDF/X standards apply to graphic content exchange. During PDF conversion, the file that is beingness processed is checked against the specified standard. If the PDF will not meet the selected ISO standard, a message appears, asking you to choose betwixt canceling the conversion or going ahead with the creation of a non-compliant file. A widely used standards for a print publishing workflow is the PDF/X format such as PDF/X‑1a.

The PDF/X-four format is reliable for live transparency and color management. This format is optimal for RIP processing, digital printers that use the Adobe PDF Print Engine, and any PDF file to be printed in Acrobat.

PDF compatibility levels

When you create PDFs, you need to decide which PDF version to use. You can modify the PDF version by switching to a different preset or choosing a compatibility option when you save every bit PDF or edit a PDF preset.

By and large speaking, unless there's a specific demand for backward compatibility, you should employ the most recent version (in this case version one.vii). The latest version will include all the newest features and functionality. However, if you lot're creating documents that will be distributed widely, consider choosing Acrobat 5.0 (PDF 1.4) or Acrobat half-dozen.0 (PDF one.v) to ensure that all users can view and print the document.

The following tabular array compares some of the functionality in PDFs created using the different compatibility settings.

Acrobat 8.0 and nine.0 also use PDF ane.vii.

Acrobat 3.0 (PDF ane.3)	Acrobat 5.0 (PDF 1.4)	Acrobat half-dozen.0 (PDF 1.5)	Acrobat 7.0 (PDF ane.6) and Acrobat 10 (PDF ane.7)

General options for PDFs

Click the General category in the Export Adobe PDF dialog box to set the post-obit options:

Clarification

Displays the description from the selected preset, and provides a place for you to edit the description. Yous can paste a description from the Clipboard.

Pages

All

Exports all pages in the current document or book.

Range

Specifies the range of pages to export in the current document. You lot tin blazon a range by using a hyphen, and separate multiple pages or ranges by using commas. This pick is unavailable when you're exporting books or creating presets.

Spreads

Exports pages together as if they were printed on the same sheet.

Do not select Spreads for commercial printing; if you do, the service provider cannot impose the pages.

Viewing

View

Initial view settings of the PDF when it's opened.

This driblet-down is enabled simply if yous select the PDF Standard - None.

Layout

Initial layout of the PDF when it's opened.

If in the Compatibility drop-down, Acrobat four (PDF 1.3) or Acrobat five (PDF ane.iv) is selected, then the following options in the Layout drop-down list are disabled:

• Ii-Upwards (Facing)
• 2-Upward (Comprehend Page)
  

Options

Embed Page Thumbnails

Embeds a thumbnail preview for each page in the PDF, increasing the file size. Deselect this setting when users of Acrobat 5.0 and later will view and print the PDF; these versions generate thumbnails dynamically each time you click the Pages panel of a PDF.

Optimize For Fast Web View

Reduces PDF file size, and optimizes the PDF file for faster viewing in a web browser by restructuring the file for folio-at-a-fourth dimension downloading (byte serving). This choice compresses text and line art, regardless of the settings you have selected in the Compression category of the Consign Adobe PDF dialog box.

If Compatibility is set to Acrobat half-dozen (PDF 1.v) or later on, tags are compressed for smaller file size. If the PDF is then opened in Acrobat four.0 or Acrobat five.0, the tags will not be visible because those versions of Acrobat cannot decompress tags.

Create Tagged PDF

During export, automatically tags elements in the story based on a subset of the Acrobat tags that InDesign supports. This includes recognition of paragraphs, basic text formatting, lists, and tables. (You tin can also insert and adjust tags in the document before exporting to PDF. See Calculation structure to PDFs.)

View PDF After Exporting

Opens the newly-created PDF file in the default PDF viewing application.

Create Acrobat Layers

Saves each InDesign layer as an Acrobat layer inside the PDF. Also exports any printer's marks you've included to a separate marks and bleeds layer. The layers are fully navigable, which allows users of Acrobat half-dozen.0 and later on to generate multiple versions of the file from a unmarried PDF. For instance, if a document will be published in multiple languages, yous can identify the text for each language in a unlike layer. A prepress service provider tin then bear witness and hibernate the layers to generate dissimilar versions of the document.

If you select the Create Acrobat Layers option when yous export a book to PDF, identically named layers are merged past default.

Create Acrobat Layers is available simply when Compatibility is set to Acrobat 6 (PDF i.five) or later.

Export Layers

Determines whether visible layers and nonprinting layers are included in the PDF. Yous can use the Layer Options settings to make up one's mind whether each layer is hidden or set every bit nonprinting. When exporting to PDF, choose whether you want to export All Layers (including hidden and nonprinting layers), Visible Layers (including nonprinting layers), or Visible & Printable Layers.

Include

Bookmarks

Creates bookmarks for table of contents entries, preserving the TOC levels. Bookmarks are created from the information specified in the Bookmarks console.

Hyperlinks

Creates PDF hyperlink annotations for InDesign hyperlinks, table of contents entries, and alphabetize entries.

Visible Guides And Grids

Exports margin guides, ruler guides, column guides, and baseline grids currently visible in the document. Grids and guides export in the same color used in the document.

Non-Printing Objects

Exports objects to which y'all have applied the Nonprinting selection in the Attributes panel.

Interactive Elements

Choose Include Appearance to include items such as buttons and movie posters in the PDF. To create a PDF with interactive elements, choose the Adobe PDF (Interactive) option instead of the Adobe PDF (Print) option. Come across Consign to interactive PDF options.

Compression and downsampling options for PDFs

When exporting documents to Adobe PDF, y'all can compress text and line art, and compress and downsample bitmap images. Depending on the settings you choose, compression and downsampling can significantly reduce the size of a PDF file with fiddling or no loss of detail and precision.

The Compression area of the Export Adobe PDF dialog box is divided into iii sections. Each department provides the following options for compressing and resampling color, grayscale, or monochrome images in your artwork.

If you plan to utilize the PDF file on the web, use downsampling to let for higher pinch. If y'all program to print the PDF file at high resolution, check with your prepress service provider before setting compression and downsampling options.

You lot should too consider whether users need to magnify a page. For case, if you lot are creating a PDF certificate of a map, consider using a higher epitome resolution and so that users tin zoom in on the map.

Downsampling refers to decreasing the number of pixels in an image. To downsample color, grayscale, or monochrome images, choose an interpolation method—average downsampling, bicubic downsampling, or subsampling—and enter the desired resolution (in pixels per inch). Then enter a resolution in the For Images To a higher place text box. All images with resolution above this threshold will exist downsampled.

The interpolation method you choose determines how pixels are deleted:

Average Downsampling To

Averages the pixels in a sample area and replaces the unabridged surface area with the boilerplate pixel color at the specified resolution.

Subsampling To

Chooses a pixel in the centre of the sample surface area and replaces the entire expanse with that pixel color. Subsampling significantly reduces the conversion fourth dimension compared with downsampling but results in images that are less polish and continuous.

Bicubic Downsampling To

Uses a weighted average to determine pixel color, which usually yields better results than the simple averaging method of downsampling. Bicubic is the slowest simply most precise method, resulting in the smoothest tonal gradations.

Compression

Determines the blazon of pinch that is used:

Automated (JPEG)

Determines automatically the best quality for color and grayscale images. For most files, this selection produces satisfactory results.

JPEG

Is suitable for grayscale or color images. JPEG compression islossy, which ways that it removes image information and may reduce image quality; however, it attempts to reduce file size with a minimal loss of information. Because JPEG compression eliminates information, it can reach much smaller files sizes than ZIP compression.

Nothing

Works well on images with large areas of unmarried colors or repeating patterns, and for blackness-and-white images that contain repeating patterns. Nada compression can exist lossless or lossy, depending on the Prototype Quality setting.

JPEG 2000

Is the international standard for the compression and packaging of image data. Similar JPEG compression, JPEG 2000 compression is suitable for grayscale or color images. It also provides additional advantages, such every bit progressive display. The JPEG 2000 choice is but available when Compatibility is set to Acrobat half-dozen (PDF ane.5) or later.

Automatic (JPEG 2000)

Determines automatically the best quality for color and grayscale images. The Automatic (JPEG 2000) option is only bachelor when Compatibility is set to Acrobat 6 (PDF 1.v) or afterwards.

CCITT And Run Length

Are just available for monochrome bitmap images. CCITT (Consultative Committee on International Telegraphy and Telephony) compression is appropriate for black-and-white images and any images scanned with an image depth of 1 bit. Grouping 4 is a general-purpose method that produces good compression for most monochrome images. Group 3, used by nigh fax machines, compresses monochrome bitmaps one row at a time. Run Length compression produces the best results for images that contain large areas of solid black or white.

Grayscale images that take been colorized in InDesign are subject to the compression settings for Colour Images. However, grayscale images colorized with a spot colour (and [None] applied to their frames) use the compression settings for grayscale.

Image Quality

Determines the  amount of pinch that is applied. For JPEG or JPEG 2000 compression, you can choose Minimum, Low, Medium, Loftier, or Maximum quality. For Zip compression, merely 8‑scrap is bachelor. Considering InDesign uses the lossless ZIP method, data is not removed to reduce file size, so epitome quality is non affected.

Tile Size

Determines the size of the tiles for progressive brandish. This pick is only bachelor when Compatibility is set to Acrobat 6 (1.v) and afterwards, and Pinch is ready to JPEG 2000.

Compress Text And Line Fine art

Applies Flate pinch (which is similar to Zero compression for images) to all text and line fine art in the document, without loss of detail or quality.

Crop Paradigm Data To Frames

May reduce file size by exporting only image data that falls within the visible portion of the frame. Do not select this option if postprocessors might require the additional information (for repositioning or bleeding an epitome, for case).

Marks and Bleeds options for PDFs

Bleed is the amount of artwork that falls exterior of the press bounding box, or exterior the crop marks and trim marks. Y'all can include bleed in your artwork equally a margin of mistake, to ensure that the ink extends all the way to the edge of the folio later on the page is trimmed or to ensure that a graphic can exist stripped into a keyline in a certificate.

You can specify the extent of the bleed and add a variety of printer's marks to the file.

Colour management and PDF/10 output options for PDFs

You tin can set the following options in the Output area of the Export Adobe PDF dialog box. Interactions betwixt Output options modify depending on whether color management is on or off, whether the document is tagged with color profiles, and which PDF standard is selected.

For quick definitions of the options in the Output expanse, position the arrow over an option and read the Description text box at the bottom of the dialog box.

Colour Conversion

Specifies how to represent colour information in the Adobe PDF file. All spot color information is preserved during color conversion; simply the process color equivalents convert to the designated color infinite.

No Color Conversion

Preserves colour data equally is. This is the default when PDF/X‑three is selected.

Convert to Destination

Converts all colors to the profile selected for Destination. Whether the profile is included or not is determined past the Profile Inclusion Policy.

Catechumen to Destination (Preserve Numbers)

Converts colors to the destination contour space simply if they have embedded profiles that differ from the destination profile (or if they are RGB colors, and the destination profile is CMYK, or vice versa). Untagged color objects (those without embedded profiles) and native objects (such as line art or type) are not converted. This option is non bachelor if color direction is off. Whether the contour is included or not is determined by the Contour Inclusion Policy.

Destination

Describes the gamut of the final RGB or CMYK output device, such as your monitor or a SWOP standard. Using this profile, InDesign converts the document's color information (defined by the source profile in the Working Spaces section of the Color Settings dialog box) to the color infinite of the target output device.

Profile Inclusion Policy

Determines whether a colour profile is included in the file. The options vary, depending on the setting in the Colour Conversion carte, whether one of the PDF/X standards is selected, and whether color management is on or off.

Don't Include Profiles

Does not create a color-managed document with embedded color profiles.

Include All Profiles

Creates a colour-managed document. If the application or output device that uses the Adobe PDF file needs to translate colors into another color space, it uses the embedded colour infinite in the contour. Earlier you select this option, turn on color management and set up profile information.

Include Tagged Source Profiles

Leaves device-dependent colors unchanged and preserves device-independent colors equally the nearest possible equivalent in PDF. This is a useful option for print shops that have calibrated all their devices, used that information to specify color in the file, and are only outputting to those devices.

Include All RGB And Tagged Source CMYK Profiles

Includes whatever profiles for tagged RGB objects and tagged CMYK objects, such as placed objects with embedded profiles. This option also includes the Document RGB profile for untagged RGB objects.

Include Destination Profile

Assigns the destination profile to all objects. If Catechumen To Destination (Preserve Color Numbers) is selected, untagged objects in the same colour infinite are assigned the destination profile so that color numbers don't alter.

Simulate Overprint

Simulates the appearance of press separations by maintaining the appearance of overprinting in composite output. When Simulate Overprint is unselected, Overprint review must be selected in Acrobat to see the effects of overlapping colors. When Simulate Overprint is selected, spot colors are inverse to their process equivalents, and overlapping colors brandish and output correctly, without Overprint Preview selected in Acrobat. With Simulate Overprint on, and Compatibility (in the General area of the dialog box) set to Acrobat 4 (PDF ane.3), you can soft-proof your document'south colors directly on the monitor before they are reproduced on a particular output device.

Ink Manager

Controls whether spot colors are converted to process equivalents and specifies other ink settings. If you make changes to your document using the Ink Director (for example, if you modify all spot colors to their process equivalents), those changes volition be reflected in the exported file and in the saved document, but the settings won't be saved with the Adobe PDF preset.

Output Intent Profile Proper noun

Specifies the characterized press status for the document. An output intent profile is required for creating PDF/X-compliant files. This carte du jour is only bachelor if a PDF/X standard (or preset) is selected in the General area of the Export Adobe PDF dialog box. The available options depend on whether color management is on or off. For example, if colour management is off, the carte lists only output profiles that lucifer the destination profile's color space. If color management is on, the output intent profile is the same profile selected for Destination (provided information technology is a CMYK output device).

Output Condition Name

Describes the intended printing status. This entry can be useful for the intended receiver of the PDF document.

Output Condition Identifier

Indicates a pointer to more information on the intended printing condition. The identifier is automatically entered for press conditions that are included in the ICC registry. This choice is not available when using either of the PDF/Ten‑3 presets or standards, because the file would fail compliance when inspected past the Preflight feature in Acrobat 7.0 Professional and later, or the Enfocus PitStop application (which is a plug‑in for Acrobat 6.0).

Registry Proper noun

Indicates the spider web address for more information on the registry. The URL is automatically entered for ICC registry names. This option is not available when using either of the PDF/X‑3 presets or standards, considering the file would neglect compliance when inspected by the Preflight feature in Acrobat vii.0 Professional and later, or the Enfocus PitStop application (which is a plug‑in for Acrobat 6.0).

Font, OPI, and flattening options for PDFs

You tin can ready the post-obit options in the Avant-garde area of the Consign Adobe PDF dialog box.

Subset Fonts When Percent Of Characters Used Is Less Than

Sets the threshold for embedding complete fonts based on how many of the font's characters are used in the document. If the per centum of characters used in the document for whatever given font is exceeded, then that specific font is completely embedded. Otherwise, the font is subsetted. Embedding consummate fonts increases file size, merely if you lot desire to brand sure you completely embed all fonts, enter 0 (nix). You can also set a threshold in the Full general Preferences dialog box to trigger font subsetting based on the number of glyphs a font contains.

OPI

Lets you selectively omit different imported graphics types when sending paradigm data to a printer or file, leaving only the OPI links (comments) for afterward treatment past an OPI server.

Preset

If Compatibility (in the General area of the dialog box) is set to Acrobat four (PDF i.iii), you lot can specify a preset (or gear up of options) for flattening transparency. These options are only used when exporting spreads with transparency in artwork.

Acrobat 5 (PDF ane.4) and afterward automatically preserve transparency in artwork. Equally a result, the Preset and Custom options are not available for these levels of compatibility.

Ignore Spread Overrides

Applies the flattener settings to all spreads in a document or book, overriding the flattener preset on an private spread.

Create JDF File Using Acrobat

Creates a Task Definition Format (JDF) file and starts Acrobat Professional for processing the JDF file. A job definition in Acrobat contains references to the files to exist printed besides as instructions and information for prepress service providers at the production site. This option is only available if Acrobat vii.0 Professional or later is installed on your machine. For more data, see Acrobat Assistance.

Add security to PDF files

When saving as PDF, y'all tin add together password protection and security restrictions, limiting not merely who tin open the file, merely likewise who can copy or extract contents, print the document, and more.

A PDF file tin can crave passwords to open a certificate (document open password) and to change security settings (permissions password). If you set any security restrictions in your file, y'all should set both passwords; otherwise, anyone who opens the file could remove the restrictions. If a file is opened with a permissions password, the security restrictions are temporarily disabled.

The RC4 method of security from RSA Corporation is used to countersign-protect PDF files. Depending on the Compatibility setting (in the General category), the encryption level will exist high or low.

Adobe PDF presets don't support passwords and security settings. If yous select passwords and security settings in the Consign Adobe PDF dialog box, and then click Salvage Preset, the passwords and security settings won't exist preserved.

Security options for PDFs

Yous can set the post-obit options when y'all create a PDF or when you apply password protection to a PDF. Options vary depending on the Compatibility setting. Security options are non available for PDF/X standards or presets.

Compatibility

Sets the type of encryption for opening a password-protected document. The Acrobat 4 (PDF 1.three) pick uses a low encryption level (40‑scrap RC4), while the other options use a high encryption level (128‑bit RC4 or AES).

Be aware that anyone using an earlier version of Acrobat cannot open a PDF document with a higher compatibility setting. For example, if you lot select the Acrobat 7 (PDF 1.6) option, the document cannot be opened in Acrobat 6.0 or before.

Require A Password To Open up The Document

Select this option to require users to type the countersign you specify to open the document.

Certificate Open Password

Specify the password that users must type to open the PDF file.

If yous forget a countersign, there is no manner to recover it from the certificate. It'southward a good idea to shop passwords in a separate secure location in instance you forget them.

Utilise A Password To Restrict Printing, Editing And Other Tasks

Restricts admission to the PDF file'due south security settings. If the file is opened in Adobe Acrobat, the user can view the file but must enter the specified Permissions password in order to change the file'south Security and Permissions settings. If the file is opened in Illustrator, Adobe Photoshop, or Adobe InDesign, the user must enter the Permissions password, since information technology is not possible to open up the file in a view-merely mode.

Permissions Countersign

Specify a password that is required to change the permissions settings. This choice is available only if the previous option is selected.

Printing Immune

Specifies the level of press that users are allowed for the PDF certificate.

None

Prevents users from printing the document.

Depression Resolution (150 dpi)

Lets users impress at no higher than 150-dpi resolution. Printing may be slower considering each folio is printed equally a bitmap image. This option is bachelor just if the Compatibility option is set to Acrobat five (PDF 1.iv) or later.

High Resolution

Lets users print at whatsoever resolution, directing high-quality vector output to Adobe PostScript and other printers that support advanced high-quality printing features.

Changes Immune

Defines which editing actions are allowed in the PDF document.

None

Prevents users from making any changes to the certificate that are listed in the Changes Allowed menu, such as filling in form fields and adding comments.

Inserting, Deleting, And Rotating Pages

Lets users insert, delete, and rotate pages, and create bookmarks and thumbnails. This pick is merely available for high (128‑bit RC4 or AES) encryption.

Filling In Form Fields And Signing

Lets users fill in forms and add digital signatures. This pick doesn't allow them to add comments or create form fields. This option is just available for high (128‑bit RC4 or AES) encryption.

Commenting, Filling In Form Fields, And Signing

Lets users add comments and digital signatures, and fill in forms. This option doesn't allow users to motility folio objects or create form fields.

Folio Layout, Filling in Form Fields, And Signing

Lets users insert, rotate, or delete pages and create bookmarks or thumbnail images, fill out forms, and add digital signatures. This option doesn't allow them to create form fields. This pick is only available for depression (40‑chip RC4) encryption.

Any Except Extracting Pages

Lets users edit the document, create and make full in form fields, and add comments and digital signatures.

Enable Copying Of Text, Images, And Other Content

Lets users select and re-create the contents of a PDF.

Enable Copying Of Content And Access For The Visually Dumb

Lets visually impaired users utilize screen readers to read and re-create the document. This selection is only available for low (twoscore‑bit RC4) encryption.

Enable Text Access For Screen Reader Devices For The Visually Impaired

Lets visually impaired users read the certificate with screen readers, but doesn't allow users to copy or extract the document's contents. This choice is available just for high (128-bit RC4 or AES) encryption.

Enable Plaintext Metadata

Allows users to copy and extract content from the PDF. This choice is simply bachelor when Compatibility is set to Acrobat half dozen (PDF 1.5) or later. Selecting this option allows storage/search systems and search engines to access metadata stored in the certificate.

Font embedding and substitution

A font can be embedded only if it contains a setting by the font vendor that permits it to exist embedded. Embedding prevents font substitution when readers view or print the file, and ensures that readers see the text in its original font. Embedding increases file size only slightly, unless the certificate uses CID fonts, a font format commonly used for Asian languages. You tin embed or substitute fonts in Acrobat or when you export an InDesign document to PDF.

Yous tin can embed the entire font, or simply a subset of the characters used in the file.

When a font cannot be embedded due to the font vendor settings, and someone who opens or prints a PDF does not have admission to the original font, some other font is temporarily substituted. To avoid problems, print only PDF files in which fonts can be embedded.

The Multiple Master typeface tin can stretch or condense to fit, to ensure that line and page breaks in the original document are maintained. The exchange cannot always match the shape of the original characters, yet, especially if the characters are unconventional ones, such equally script typefaces.

If characters are anarchistic (left), the substitution font does not match (correct).

Set up a certificate for onscreen viewing

With its pocket-size file sizes, platform independence, and online navigation, Adobe PDF is an ideal format for distributing documents electronically and viewing them on-screen. You tin transport Adobe PDF documents to other users equally e-post attachments, or you tin distribute the documents on the web or on an intranet.

For information on creating attainable PDF documents, encounter Adobe InDesign CS4 accessibility.

The following guidelines apply to electronically distributed Adobe PDF files:

• Before putting Adobe PDF documents on a website, check to see that the text, artwork, and layout in the documents are consummate and correct.

• Make certain that table of contents entries, hyperlinks, and bookmarks are generated correctly. Table of contents entries are generated automatically from information in the Bookmarks panel.

• Set up passwords and other security options.

• Use a file name of no more than than 8 characters, followed past an extension of upwardly to three characters. Many networks and e-mail programs shorten long file names.

• Brand sure that the file name has a PDF extension if users volition view the file on a Windows calculator or on the Internet.

• To utilise predefined Adobe PDF export settings for on-screen viewing, choose Smallest File Size.

Adobe PDF files exported from InDesign documents that contain overprints or transparency effects are best viewed in Acrobat 5.0 and later, or Adobe Reader vii.0 and later, with the Overprint Previewselection selected.
