I agree that these are typically visual artefacts that don't show up in print. Of course they won't appear if you create a PDF file that still includes transparency, eg by exporting directly from the design app to a PDF 1.4 or later file. As soon as you use PostScript, the transparency is flattened and the lines pop up because of that. Viny, I think you mean ‘atomic regions’.

A place where transparency is merged with the background. It won't print but it is annoying. Zoom in and sometimes they go away. This is called dynamic regions in the PDF file.

I would like you to check the PDF in the Acrobat Reader Version 4.0 and 5.0. The lines would appear in the higher version of the Acrobat Professtional. This is a visual inflation associated with InDesign and Acrobat Professtional, but in actual there is no problem with the source file. Regards, Dinesh Raghav This happens with the InDesign files.

I was working to a very tight deadline. The file was in Indesign with a ai background. When I placed a transparent tiff over top of the background it looked good. When I exported it as an ordinary PDf file it looked fine. But when I sent it to the PS printer to create a high res PDF file to send on to the Print Co a fine line appeared around the outside of the transparent tiff. When printed on my laser printer the lines did not show. I could not risk sending it to the Print Co in case these fine lines showed up on the final printed product. What caused the outline around the Tiff on the PS PDF file, and would these lines have shown when Printed at the Print Co, even though on my home printer they didnt show? I would really appreciate any help you can give to me on this. Many thanks. AJS Hello there,
