resolution or color space. It’s simply been extracted from the InDesign

file and saved to disk.

Embedded Images

An icon indicates that a graphic is embedded in the InDesign le (le). To edit the graphic,

you must rst unembed it and save it as an external le. Select the link in the panel, and

choose Unembed File from the panel menu. Click No in the dialog box that appears (right).

Copied and pasted artwork

Vector artwork that shows no entry in the Links panel has likely been

copied and pasted from Illustrator. This should present no problem

during imaging. Pasting content from Illustrator offers the advantage of

being completely editable within InDesign, but it has no relationship

with the original Illustrator file. The artwork is now part of the InDesign

file, independent of the Illustrator file from which it was copied, as if it

had been drawn in InDesign. Thus, editing the original file in Illustrator

does not change the InDesign file.

Image content copied and pasted from Photoshop, however, presents

some problems. Even if the original image was CMYK, the copied

content is RGB. There is no link to the original file, and thus no

editability and no way of determining the file name of the original file.

Essentially, it’s a screen shot.

If possible, obtain the original Photoshop image from the file creator and

place, rather than copy and paste, it in the InDesign file. If you cannot

obtain the original image, select the image (or frame) in InDesign, and

copy to the clipboard. Launch Photoshop and create a new, empty file

(File > New). Accept the size Photoshop indicatesit’s based on the

dimensions of the image content you copied to the clipboard. Paste the

image; in Photoshop CS5, it becomes a Vector Smart Object. Press

Return or Enter after pasting. Then, choose Layer > Smart Objects >

Rasterize. Perform the desired edits, change color space if necessary,

and save the file. To update the InDesign file with the new file, select the

frame containing the pasted image, choose File > Place, and navigate to

the saved image you created. Above all, advise your customer not to

copy and paste from Photoshop in the future. While Photoshop and

InDesign allow it, it’s not a good production practice.

Determining image resolution and color space

To check the resolution and color space of an individual image, select it

and consult the Info panel (Window > Info). However, not all formats

can be determined in this manner: while the Info panel displays

information for TIFF, JPEG, PSD, and Photoshop EPS files, it cannot

display information about PDFs or Illustrator AI or EPS files containing

images. Pay special attention to the Actual ppi (pixels per inch) and

Effective ppi values: Actual ppi describes the original resolution of the

image as it was saved from Photoshop; Effective ppi describes the

resolution of the image as it is used in InDesign. For example, a 300 ppi

image that has been scaled at 200% in InDesign would have an Actual

ppi of 300 x 300, and an Effective ppi of 150 x 150. This information is

useful in determining if an image has been scaled beyond a desired

resolution.

Using the Info Panel

Selected images (PSD, TIFF, EPS, and JPEG) display their resolution and color space in the

Info panel.
