Symptoms

When PS/M RIPs Adobe^® files that contain transparent text on top of images or vignettes, or text on top of transparent images, the text appears jagged in the resulting image.

Cause

Occasionally, PS/M cannot successfully RIP Adobe files that contain transparent text or transparent images.

Solution

When creating an EPS file in Adobe Illustrator:

1. From the Type menu, ensure the Create Outline option is cleared.
2. From the Object menu, choose Flatten Transparency.
3. Slide the cursor to 100%. Adobe Illustrator® flattens the file, which produces the best image results.
4. Save the file in EPS (encapsulated PostScript®) format.
5. In PS/M, RIP the PostScript file using CT Quality.

Note: If you are using Adobe InDesign^® to create an EPS file, use the equivalent options as those described above for Adobe Illustrator.

When creating a PDF 1.4 file in Adobe Illustrator:

1. In the Transparency - Quality/Speed box of the PDF Params window, select Highest, as shown below.

2. In the Preferences window, under RIP, select CT Quality > CT Edges > LW Resolution, as shown below.

Note:
Creo does not recommend that you save files in Adobe applications with the Create Outline option selected, because hairlines sometimes appear around the transparent text after you RIP the file.

If, however, you choose to select the Create Outline option in an Adobe application, you can prevent hairlines from appearing by RIPing the file at 600 dpi and specifying whole number values for CT and LW. For example, LW=2400 and CT=600 (or 400).
