  Working With EPS Files in QuarkXPress™ and Photoshop® - Part Two

7. Next, open QuarkXPress and create a new document. Make a new picture box with the Rectangle Picture Box tool (more here on how to do this). Load the "CD.eps" image into the picture box by clicking File > Get Picture. You should see a low resolution preview of the EPS file in the document. Save this document as "cd.qxd".


Note: When you load an image into a picture box in a QuarkXPress document, Quark™ will create its own low resolution preview image from the preview image saved in the EPS file. It creates all it's image previews using the CMYK color model even though the original images use the RGB or Grayscale color models. More here on color models.

If the image files are missing at output time, Quark will print using these internal preview images. You will get one plate each for Cyan, Magenta, Yellow and Black by default when printing out a color separated job even though you may be doing a one color or two color spot job. More here on process color vs. spot color.

8. Create another new QuarkXPress document and make a rectangular picture box as before only this time load the "CD no preview.eps" image into the picture box. Save this document as "cd no preview.qxd". Your screen should look something like the one below left. Notice that without the screen preview, Quark merely reports that this is a PostScript® picture. But also note the shape of the gray area. This indicates that Quark recognizes the clipping path. The reason you do not see the image is because QuarkXPress does not use PostScript to render images onscreen. Now if you were to load this same EPS file into an Adobe® product like Illustrator®, you can see the image (below right). This is because Adobe uses PostScript to render images onscreen and does not need a preview image for you to see it.

9. Now let's do something different. Open the CD.eps file into a text editor to view the PostScript code. This is why we saved the EPS file using ASCII encoding. You couldn't do this if it was saved as a binary file. The image below shows a close up of the code.

10. EPS files are PostScript. They can be encoded as straight ASCII as in this example or they can be encoded in a more compact form such as binary or JPEG. The important point to remember here is that where you save the EPS with a preview there are two separate images in the PostScript code. When you look at a jagged image onscreen or in print, you are most likely looking at the low resolution preview, not the actual high resolution image.
