I have been having problems with pictures in both Photoshop and InDesign appearing blurry or pixilated when printed or in print preview. In Photoshop I even used an original file from a photographer. I can use these same file in a Word document and they come out looking like they should. Why? Help!!
What is the size and resolution in Photoshop, and have you scaled them in ID?
Ar you using File > Place... to bting them into ID, or pasting?
If you're printing directly from InDesign, the Optimized Subsampling default may be the culprit.
Go to Print > Graphics > Images and choose "All" from the Send Data: menu.
Better yet, export your InDesign work to PDF using the PDF/X-4 preset, then print from Acrobat.
