Adobe InDesign/InDesign pdf lines

Question
PDF Hairlines and are caused by InDesign tiling the image under the text
(cutting it into different blocks kind of like a puzzle of squares). Can you get rid
of this problem by upgrading to CS3 and or Acrobat CS3?

Answer
Hi Linda, thanks for the question.

Well, I wouldn't consider this a problem. InDesign does this because it's the most efficient way to flatten the transparency in the document when exporting to PDF. You can leave your file unflattened by saving for Acrobat 6 or higher, but any problems you may have with flattening while printing won't show up until it's too late. Saving your PDF in a the PDF/x-1:2001 format is the safest way to save a file you will use to print.

Hope this helps!

Experience

After starting my design career using QuarkXPress and PageMaker for many years, the release of InDesign instantly caught my eye. Being one of the reasons for Adobe buying Aldus, I knew this would change the publishing world very quickly. I started using InDesign's first release and haven't looked back. I have dedicated my work and much of my spare time using InDesign to its fullest—and it's paid off. My workflow is quicker, my computer runs smoother, and my files print cleaner and without problem.
