Image Quality Determines the amount of compression that is applied. The available options depend on the

compression method. For JPEG Compression, Illustrator provides Minimum, Low, Medium, High, and Maximum

Quality options. For ZIP compression, Illustrator provides 4-bit and 8-bit Quality options. If you use 4-bit ZIP

compression with 4-bit images, or 8-bit ZIP compression with 4-bit or 8-bit images, the ZIP method is lossless; that is,

data is not removed to reduce file size, so image quality is not affected. Using 4-bit ZIP compression with 8-bit data can

affect the quality, however, because data is lost.

Tile Size This option is only enabled when its corresponding Compression setting is JPEG2000. It determines the size

of the tiles for progressive display.

Compress Text And Line Art Applies compression to all text and line art in the file. This method results in no loss of

detail or quality.

Mark and bleed options for PDF

Bleed is the amount of artwork that falls outside of the printing bounding box, or outside the crop marks and trim

marks. You can include bleed in your artwork as a margin of error—to ensure that the ink extends all the way to the

edge of the page after the page is trimmed or to ensure that an image can be stripped into a keyline in a document.

The Marks & Bleed area of the Save Adobe PDF dialog box lets you specify the extent of the bleed and add a variety of

printer’s marks to the file.

All Printer’s Marks Enables all printer’s marks (Trim Marks, Registration Marks, Color Bars, and Page Information) in

the PDF file.

Printer Mark Type Lets you choose Roman printer’s marks, or Japanese marks for pages printed in Asian languages.

Trim Marks Places a mark at each corner of the trim area to indicate the PDF trim box boundaries.

Trim Mark Weight Determines the stroke weight of the trim marks.

Registration Marks Places marks outside the artboard for aligning the different separations in a color document.

Offset Determines the distance of all printer’s marks from the edge of the artboard. The trim marks are at the edge of

the space determined by the offset.

Color Bars Adds a small square of color for each spot or process color. Spot colors converted to process colors are

represented using process colors. Your service provider uses these marks to adjust ink density on the printing press.

Page Information Places page information outside the artboard of the page. Page information includes the filename,

page number, current date and time, and color separation name.

Use Document Bleed Settings uses the document’s bleed settings instead of the bleed settings in this dialog box.

Bleed Top, Bottom, Left, Right Controls the bleeds for the artwork. When the button is selected, these four values are

proportional—editing one will update the values in the other three.

Color management and PDF/X options for PDF

You can set the following options in the Output section of the Save Adobe PDF dialog box. Interactions between Output

options change depending on whether Color Management is on or off and which PDF standard is selected.

Color Conversion Specifies how to represent color information in the Adobe PDF file. When you convert color objects

to RGB or CMYK, also select a destination profile from the pop-up menu. All spot color information is preserved

during color conversion; only the process color equivalents convert to the designated color space.

No Conversion Preserves color data as is. This is the default when PDF/X-3 is selected.
