Linked and Embedded images

Raster images can either be embedded in an Illustrator file, or placed in

an Illustrator file with an external link (as in InDesign). Each option has

advantages and disadvantages:

•Linking images requires that the images be supplied in addition to the

Illustrator le for proper output. Linked images can be edited in Pho-

toshop and then updated with the Links panel in Illustrator. If you do

not move the image to another directory, the link will remain current.

However, if you move or rename the image, you will have to update

the link in Illustrator.

•Embedding images avoids the need to send images separately, but

does not provide the recipient access to the original image informa-

tion for editing. us, if a color correction were necessary for an

embedded image, the customer would have to supply the image for

you to correct. You then update the image in the Illustrator le, replac-

ing the embedded image with the corrected image. At that point, you

can choose whether to embed or link the corrected image. Note that

embedding an image increases the le size of the Illustrator le by

approximately the amount of the image’s size on disk (that is, embed-

ding a 2 MB image increases the le size of the Illustrator le by ap-

proximately 2 MB).

ird-Party Solution

e Scoop plug-in

(www.worker72a.com) for Illustrator can gather fonts and images needed by Illus-

trator les, much like InDesign’s Package feature. e plug-in can also unembed

embedded images without relying on the Acrobat workaround described below.

If you need to edit an embedded image, and the customer cannot

supply the image for editing, there is a workaround to enable you to

extract the image, using the TouchUp features of Acrobat X Pro:

1. Save the Illustrator le as an Illustrator PDF, with the following set-

tings:

•Adobe PDF Preset: Illustrator Default

•Compression: Do Not Downsample; No Compression

•Output: No Color Conversion

2. Open the PDF in Acrobat X Pro.

3. Using the TouchUp Object tool (Tools > Advanced Editing > Touch-

Up Object Tool), select the image, right-click (Windows) or Control-

click (Mac OS) and choose Edit Image from the context menu that

appears. Adobe Photoshop opens the image for editing.

4. In Photoshop, perform the necessary edits on the image. Although

the TouchUp method is intended to allow you to write an edited

image back into a PDF, for this workaround you must choose Save

As to save the image on disk for use in other applications. For best

results, save the image as a Photoshop native (PSD) le or TIFF im-

age.

5. Return to Illustrator. Open the Links panel (Window > Links), select

the embedded image in the Links panel, and choose Relink from

the panel menu. Navigate to the corrected image, and choose

Place in the dialog box. e embedded image is replaced with

the corrected version of the image, and all transformations are

retained. e new image will be linked to the Illustrator le, rather

than embedded.

You can now discard the PDF; its only purpose was to help you capture

the image at full resolution for editing.

When you examine customer files to pinpoint issues before they can

have an impact on your workflow, make it a habit to use the Illustrator

tools that can help you easily find common problems.
