I am trying to place a Photoshop TIFF into an InDesign document but I am getting a pixelated/jagged version of the TIFF. What could be causing this? The original art looks fine in Photoshop. It is a TIFF of less than 8 MB, CMYK, about 3.5 by 3.5 inches. It includes image and text both created in Photoshop. When placed into an InDesign file, the art looks awful and the text is even worse. The text can barely be deciphered. I tried exporting the TIFF to PDF and placing that file, but it also looks bad.
Any solutions anyone?
When you have text in a Photoshop file, use PDF. But don't export it to PDF, save the file in Photoshop as PDF with Photoshop defeault settings.
If not text ot vectors are in the file, use PSD
Does your image have enough pixels?
Do you have any reason why you place a cmyk image into InDesign?
How it looks in ID is basically irrelevant. How does it look in print or an exported PDF? Did you scale the image in ID?
In Photoshop, which is a pixel editior, you are viewing the actual image pixels. In ID, which is a page layout app, you are looking at a screen preview jpeg that may or may not look terrific, depending on the image. If you've scaled the image you are chagning the "effective resolution" and it may not be high enough. You didn't mention waht it was in Photoshop at the saved dimensions, so it's hard to know if there was ever enough resolution to prevent jaggies. It's highly unlikely that text created in photoshop will NOT look pixelated unless the effective resolution is well north of 600 ppi.
ID can convert the RGB data tot he appropriate CMYK output profile for the output device during export to PDF. Unless you actually tweak the CMYK file after conversion in Photoshop there is no advantage to using CMYK, and plenty of downside in terms of multi-purposing.
You can check by selecting the image and looking in the Info panel. The importan number is the effective ppi.
But you should take Willi's advice and save as PDF from Photoshop rather than as TIFF if you haven't already rasterized the text. That will keep the text vector and crisp in ID.
