Creates a PDF even if the PostScript file does not meet the requirements of the standard, and notes these problems in the report.
Creates a PDF only if the PostScript file meets the requirements of the standard, and is otherwise valid. Flags the PostScript file as noncompliant if one of the reporting options is selected and a trim box or art box is missing from any page.
Computes values for the trim box based on the offsets for the media box of respective pages if neither the trim box nor art box is specified. The trim box is always as small as or smaller than the enclosing media box. Computes values for the bleed box based on the offsets for the trim box of respective pages if the bleed box is not specified. The bleed box is always as large as or larger than the enclosed trim box. If your workflow requires that the document specify the output intent, choose None.
Output Condition Identifier Acrobat Pro. Indicates the reference name that is specified by the registry of the output intent profile name. For more information, click the question mark next to the option. Output Condition Acrobat Pro. Describes the intended printing condition. This entry can be useful for the intended receiver of the PDF. Indicates the web address for finding more information about the output intent profile.
The registry name is optional, but recommended. Indicates the state of trapping in the document. If the document does not specify the trapped state, the value provided here is used. If your workflow requires that the document specify the trapped state, choose Leave Undefined.
The latest version will include all the newest features and functionality. The following table compares some of the functionality in PDFs created using the different compatibility settings.
Note: Acrobat 8. PDFs can be opened with Acrobat 3. However, features specific to later versions may be lost or not viewable. Most PDFs can be opened with Acrobat 4.
Cannot contain artwork that uses live transparency effects. Any transparency must be flattened prior to converting to PDF 1. Supports the use of live transparency in artwork. The Acrobat Distiller feature flattens transparency.
You can save and reuse your own Adobe PDF preset definitions. You can also share a custom preset by sending a copy of the resulting file to other users.
Those users can then add it to the Distiller applications installed on their own computers. PDF settings files have the extension. Custom preset files are stored in the following locations. The settings file appears as the selected option in the Default Settings menu.
When converting PostScript files to PDF, you can compress vector objects such as text and line art and compress and downsample images. Line art is described with a mathematical equation and is usually created with a drawing program such as Adobe Illustrator. Images—whether color, monochrome, or grayscale—are described as pixels and are created with applications like Adobe Photoshop or by scanning.
Monochrome images include most black-and-white illustrations made by paint programs and any images scanned with an image depth of 1 bit. When you downsample or decrease the number of pixels , information is deleted from the image.
With Distiller, you specify an interpolation method—average downsampling, bicubic downsampling, or subsampling—to determine how pixels are deleted. Depending on the settings you choose, compression and downsampling can significantly reduce the size of a PDF with little or no loss of detail and precision.
When Distiller processes a file, it normally applies the compression settings to images throughout the file. However, you can assign different compression and downsampling methods to individual images. Before you create a PDF, you can take various approaches to applying different compression and downsampling options to the individual images that will go into that PDF:. When you are ready to create the PDF in Distiller, be careful to deselect the compression and downsampling or subsampling options.
Create separate PostScript files for each part of the document that you want to process differently, and use different compression options to distill each part. Then use Distiller to merge the files into a single PDF.
When you create color, grayscale, and monochrome images in an art application such as Adobe Photoshop CC , select the compression and downsampling settings that you want when you save each image from within that application.
Insert Distiller parameters before images in a PostScript file. You can use this technique to process every image in a document differently. This technique is the most difficult, because it requires knowledge of PostScript programming. This option overrides settings you selected in the Adobe PDF dialog box.
Works well on images with large areas of single colors or repeating patterns, and for black-and-white images that contain repeating patterns.
Acrobat supports only 8-bit ZIP compression, which is lossless ; that is, data is not removed to reduce file size, so image quality is not affected. Note: Adobe implementation of the ZIP filter is derived from the zlib package of Jean-loup Gailly and Mark Adler, whose generous assistance we gratefully acknowledge.
Suitable for grayscale or color images, such as continuous-tone photographs. JPEG is lossy , which means that it removes image data and may reduce image quality; however, it attempts to reduce file size with the minimum loss of information. Available only 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.
Group 4 is a general-purpose method that produces good compression for most monochrome images. Group 3, used by most fax machines, compresses monochrome images one row at a time. Produces the best results for images that contain large areas of solid white or black. Legal Notices Online Privacy Policy. Adobe PDF conversion settings Search. Adobe Acrobat User Guide.

Photoshop 1. Click Save. In the Save Adobe PDF dialog box, choose an Adobe PDF preset specifying whether the Photoshop file will be printed on a desktop printer or proofer, sent to a commercial printer, distributed by email, displayed on the web, and so on. For details, see Adobe PDF presets.
Microsoft PowerPoint 1. First, make sure your slide is designed to the correct size for printing. Save the files as pdf. Microsoft Word — MAC 1. In the Save As box, type a name for the file. To avoid duplication of layer names in the PDF, you can merge the layers on export. If this option is not selected, layer names appear separately under each document name. To select this option, you must use Acrobat 6 PDF 1. For PDF files that are intended to be distributed for viewing purposes only, you may want to reduce the size of PDF files when you export from InDesign.
In the Compression area, downsample images to 72 pixels per inch, select automatic compression, and select either low- or medium-image quality for color and grayscale images.
When you work with photographic images, use Automatic JPEG compression; when you work with images that are mostly solid color, such as charts and graphs, use ZIP compression.
These settings are designed to balance file size with quality, depending on how the PDF is used. You can also create and share custom presets for your unique output requirements. A few of the presets listed below are not available until you move them—as needed—from the Extras folder where they are installed by default to the Settings folder. Some presets are not available in some Creative Suite components. Review your PDF settings periodically. The settings do not automatically revert to the default settings.
High Quality Print. Creates PDFs for quality printing on desktop printers and proofing devices. This preset uses PDF 1. These PDFs can be opened in Acrobat 5. Illustrator Default Illustrator only. Creates a PDF in which all Illustrator data is preserved. PDFs created with this preset can be reopened in Illustrator without any loss of data.
Oversized Pages Acrobat only. Creates PDFs suitable for viewing and printing of engineering drawings larger than x inches. Used for long-term preservation archival of electronic documents. Compliant files must contain information describing the printing condition for which they are prepared.
The PDF created in this setting can be opened in Acrobat 4. Press Quality. In this case, the quality of the content is the highest consideration. The objective is to maintain all the information in a PDF file that a commercial printer or print service provider needs to print the document correctly.
This set of options uses PDF 1. Note : Before creating an Adobe PDF file to send to a commercial printer or print service provider, find out what the output resolution and other settings should be, or ask for a.
