Introduction

The underlying approach to printing in Adobe® Illustrator® CS has been completely

redesigned to make the printing process much faster, easier, and more reliable. You’ll have

complete control over the printed output while streamlining the process for printing. It’s

not necessary to save artwork to EPS or PDF and place it into a page layout application to

print the artwork. When your job doesn’t require layout to combine it with other content,

Illustrator CS gives you the control you need within one intelligent user interface to print

directly. You’ll not only bypass several tasks to save an EPS ﬁle and incorporate it into

another application, but you retain a live document that can be edited up until the time it is

printed. Device-speciﬁc settings and rendering are held off until print time to ensure the job

is fully optimized for the output device.

This document will guide you through every aspect of the printing process in Illustrator CS

including working with other Adobe and non-Adobe applications, setting up documents

for print, troubleshooting, and getting the best output. It is not only a technical reference

but is also a useful training tool for your staff. We welcome you to explore the new printing

features in Illustrator CS and use this information to streamline the print workﬂow for your

shop.

New features for print service providers

Following is a partial list of the improvements to the printing process implemented in Adobe

Illustrator CS. Many of these features were developed after listening closely to the input and

requests from print service providers, then incorporating those needs into the product. The

result is a signiﬁcantly enhanced print experience that will save you time and increase the

reliability and predictability of your printing process.

Streamlined printing

The printing interface in Illustrator CS has been completely rethought from the print/

prepress service provider’s point of view. The need for Page Setup and Separations Setup

dialog boxes has been eliminated and all print functionality has been consolidated into the

new comprehensive Print dialog box. This uniﬁed interface makes it easier to specify print-

ing options quickly and accurately to achieve consistent and reliable output.

A preview is always visible in the Print dialog no matter which panel is selected. It displays

a thumbnail view of your artwork and how current print settings will interact with your

selected media, including the current print area, orientation, and even printer’s marks and

bleeds.

This is the newly designed Print dialog accessed from File > Print. Notice the extensive list

of additional options on the left.

Save print presets of all your print settings for every device you print to, including proofers

and production devices. Presets save time, eliminate mistakes, and automate common

printing tasks. Illustrator CS comes with three predeﬁned print presets, and you can create

your own as well.

Most printing devices and the PostScript/EPS ﬁle format cannot process transparency

natively, so transparency effects must be ﬂattened. Similar to Adobe Photoshop®, InDesign®,

and Acrobat® 6.0 Professional, ﬂattening in Illustrator CS removes the live transparency

effects and creates individual objects that take on the same appearance as the original

transparent objects. The ﬂattened results are no longer live and cannot be edited. Illustrator

CS provides enhanced controls for ﬂattening transparent artwork as you print or export it,

so you can make trade-offs between quality and speed. You can even save common settings

as transparency ﬂattener presets that can also be used when printing or creating an Adobe

PDF ﬁle.

Access this dialog from the File > Print, Advanced tab, Custom button.

Complete control over print set tings

Not only has the print user interface been streamlined, but you get increased control over

individual print settings as well, providing the complete output experience needed to print

directly from Illustrator.

Printer’s marks (trim, registration, color bar, and page information marks) can be individu-

ally selected in Illustrator CS, so you can print any combination of them. You can also

specify the weight of the trim marks, the offset distance from the artwork, and whether to

use Roman or Japanese printer’s marks. Bleed settings are also independently deﬁned for

each edge of the page, or you can set a uniform distance along all four sides of the artboard.

You can also set printer’s marks and bleeds when saving to PDF.

When printing oversized artwork on standard paper sizes, use the new Fit to Page option

which automatically maintains the proper aspect ratio when scaling down to the media. Or

use the Custom Scale option to specify a percentage to scale the artwork, as well as whether

the width and height are to be scaled separately or in proportion to each other. New tiling

controls in Illustrator CS make it easy and intuitive to print large designs on multiple pages.

In addition to the existing page tile settings deﬁned on the artboard using the Page tool,

use the new Print dialog to tell Illustrator to tile full pages or imageable areas. You can also

control the placement of the artwork by clicking a point on the Placement icon or by specify-

ing the coordinates for the origin.

Adobe Illustrator CS has added support for printing in-RIP separations to devices (Adobe

PostScript 3™ RIPs, some Adobe PostScript Level 2 RIPs, and some LanguageLevel3 RIPs)

that support this feature. In-RIP separations print more quickly because only one PostScript

ﬁle—rather then four or more—is sent to the RIP. It also enables further in-RIP processing

such as trapping and imposition. You no longer need to load an EPSF Rider ﬁle to the device

(as you had to in earlier versions of Illustrator). Instead, you can customize printer output

features—dot characteristics, screen angles, and screen resolutions—directly from the Print

dialog for individual inks.

Access this dialog from File > Print, Output tab. The Frequency, Angle, and

Dot Shape values can be edited directly.

When printing layers with Illustrator CS, choose to print all layers, visible layers, or all

visible, printable layers. This gives you the ability to print only selected objects as either

composite output or separations, making it easier to proof or print comps of individual parts

of complex artwork.

Enhanced PDF support

Illustrator CS introduces new support for natively creating Adobe PDF ﬁles, including com-

patibility with Acrobat 6.0 and the Adobe PDF 1.5 format. PDF ﬁle creation from Illustrator

is more closely aligned with creating PDF ﬁles using Acrobat Distiller. The same compres-

sion options are available, including the new JPEG 2000. Security options for importing and

exporting Adobe PDF ﬁles can be set, including password-protection, encryption method

(40-bit or 128-bit), and whether printing, content copying and extraction, and other changes

are allowed. Just before saving the ﬁle, check the Summary to see a list of all your PDF ﬁle-

creation settings and ensure everything is set up as intended.

Streamline Adobe PDF ﬁle creation by saving all your settings in named PDF presets,

ensuring consistent PDF ﬁle creation. You can even create printer’s marks and bleeds in the

resulting PDF ﬁle. Create your own preset values or use the predeﬁned presets included in

Illustrator CS:

• Illustrator PDF for optimal preservation of transparency when exporting to other

applications

• Press PDF for automatically ﬂattening transparent elements for ﬁnal print output

• Acrobat 6 Layered PDF to export top-level layers in Illustrator ﬁles to the Adobe PDF 1.5

ﬁle format. Acrobat 6 can display layers as optional content, such as alternative designs or

multilingual text

Some applications only support placing artwork as Adobe PDF version 1.3 which cannot

include live transparency. All transparency must be ﬂattened when saving to Adobe PDF

1.3. Illustrator CS provides enhanced controls for ﬂattening transparent artwork so you can

make trade-offs between quality and speed. Use any of the predeﬁned transparency ﬂattener

presets, or create your own to ensure consistency and save time.

New text composition engine

Adobe Illustrator CS has an entirely new text composition engine which includes advanced

support of OpenType fonts, the standard jointly developed by Adobe and Microsoft.

OpenType brings the advantages of both TrueType and PostScript font formats into a new

format that takes advantage of Unicode character encoding, and makes sharing documents

across platforms easier because the same font ﬁle can be used by Mac OS and Windows®.

The new text engine in Illustrator CS requires that when opening a document created in an

older version of Illustrator, type objects must be updated to the Illustrator CS type engine in

order to be edited. Upon opening the document, you choose whether to have the text remain

as it was designed until you decide to edit it, or to update all type objects immediately.

You can easily identify missing fonts in Illustrator CS to quickly locate and ﬁx problems.

Illustrator CS automatically highlights fonts that are used in the document but not available

on the system so you can either install them yourself, or replace them with installed fonts.

Other features for print service providers

Illustrator CS lets you reliably print and export linked EPS and Adobe PDF ﬁles that interact

with transparency. When creating color separations, spot colors are maintained rather than

converted to process, unless speciﬁed otherwise in the print settings. Photoshop users can be

conﬁdent that spot colors will be retained, even in linked duotones and tritone images that

interact with transparency and are set to overprint.

There is a tighter integration between Photoshop and Illustrator CS, with layered ﬁles

moving between the applications more readily, maintaining as much of the layer

deﬁnitions as possible. Both applications now share the same text composition engine,

which signiﬁcantly improves text editability. Multiple spot channels can be imported and

16-bit color data can be converted to 8-bit on import, so you won’t have to keep two versions

of your original ﬁle.

Whether printing or using any other functionality, you’ll work faster with the increased

performance in Illustrator CS. You’ll immediately feel the more interactive experience when

scrolling around the artboard, copying and pasting, saving ﬁles, and printing.

Working with other ﬁles & applications

While all design and printing can be done within Illustrator, in many situations designers

create ﬁles from Illustrator for placement in another application, or place components into

Illustrator. This section details how to best save and input EPS ﬁles, manage linked ﬁles, and

understand the ins and outs of working with other applications, speciﬁcally Adobe InDesign,

Adobe Photoshop, and QuarkXPress™.

Creating EPS files

Illustrator CS offers three different ways to create EPS ﬁles for placement in other applica-

tions.

Save As: As with previous versions of Illustrator, you can save an Illustrator EPS ﬁle by

choosing File > Save As. This option saves to Illustrator CS EPS format, the only version of

EPS that preserves text using the new text engine.

Best Practice:

You should always

place Illustrator

artwork as native

Illustrator CS format

or PDF 1.4 or 1.5, if

possible, to retain

live artwork and

editability. Both Adobe

InDesign and Adobe

Photoshop place

native Illustrator ﬁles.

Export: Other ﬁle formats are available for output using File > Export.” Saving to earlier

versions of EPS can be done from File > Export by selecting Illustrator Legacy EPS. Since

earlier versions used the older text engine, saving to Illustrator Legacy EPS will likely cause

text reﬂow if Preserve Text Editability is chosen as the Export option. You also have the

option to Preserve Text Appearance which retains the appearance of the text both on screen

and in print, and will not cause text to reﬂow. For details, see “New Adobe Text Engine.”

Live transparency is preserved in the Illustrator 9 or 10 EPS formats for later editing in

Illustrator. These EPS ﬁles are considered ﬂattened if placed into page layout applications. If

you save as Illustrator 8 or earlier, text will be converted to outlines, spot colors will be con-

verted to process, and transparency will be discarded or ﬂattened. You are given the choice

to Preserve Paths, which discards transparency, or Preserve Appearances and Overprints,

which ﬂattens transparency in the artwork. Illustrator CS uses the currently selected ﬂatten-

ing preset to determine what settings to use for ﬂattening.

Using E PS f iles from other applications

It is generally better to link images rather than to embed them, especially when updates may

need to be made later. Illustrator CS does not require that you embed images. Rather, linked

images retain spot colors and can interact with transparency as described earlier.

Embedded EPS: You can embed EPS artwork into an Illustrator document by using the

Open command, the Place command (which can also link the ﬁle), the Paste command, or

the drag-and-drop feature. Keep the following points in mind when embedding EPS artwork.

• When you open or embed an EPS ﬁle, Illustrator converts all objects to native Illustrator

objects. If the ﬁle contains data that Illustrator doesn’t recognize, some loss of data may

occur. As a result, unless you need to edit the individual objects in an EPS ﬁle, you should

link to the ﬁle rather than open or embed it.

• When you embed an EPS ﬁle that was created in another application, Illustrator ﬂat-

tens any transparency contained in the ﬁle. If you are placing transparent artwork into

Illustrator, use PDF 1.4 or 1.5 format instead.

• Occasionally you may encounter a warning when opening an Illustrator document

containing embedded EPS images. If the original EPS image cannot be found, you will be

prompted to extract it, which by default will put it into the same directory as the current

document. Although the embedded ﬁle does not preview in the document, the ﬁle will

print correctly.

Linked EPS: Use File > Place with the Link check box selected to link an EPS ﬁle to the

current Illustrator document. One of the advantages of linking ﬁles rather than embedding

is that when you make changes to a source ﬁle, the changes are applied to the linked artwork

when the link is updated in Illustrator.

Because of the feedback Adobe received from users, Illustrator CS now includes the ability

to reliably print and export linked EPS and Adobe PDF ﬁles that interact with transparency.

Using Illustrator CS to create color separations means spot colors are maintained rather than

converted to process colors, unless speciﬁed otherwise in the print settings. Even in linked

duotones and tritones that interact with transparency and are set to overprint, spot colors

are retained, giving you control over how spot colors are handled.

Keep in mind the following when using linked EPS ﬁles.

• If you are color managing artwork in a document, embedded EPS images are part of

the document and therefore color managed when sent to a printing device. Linked EPS

images are not color managed.

• If you import an EPS color that has the same name as a color in your document but a

different deﬁnition, Illustrator displays an alert. Select Use Linked File’s Color to replace

the color in your document with the EPS color in the linked ﬁle. Select Use Document’s

Color to leave the swatch as is and to resolve all color conﬂicts using the document’s color.

The EPS preview may be incorrect, but it will print to the correct plates. Selecting Apply

to All will resolve all color conﬂicts using the deﬁnition you choose.

• If a linked EPS ﬁle isn’t visible in the document window, the ﬁle’s preview may be missing.

This can happen when transferring EPS ﬁles saved with PICT previews from Mac OS to

Windows. To restore the preview, resave the EPS ﬁle with a TIFF preview. (See “Creating

EPS ﬁles.”)
