Hey guys, I have a problem with the transparency in indesign. I used transparent .png files in my indesign document, exported it in pdf and it all looks like it should. But then when I did a few test prints, I noticed that there are grey-ish boxes around all the files that were supposed to be transparent!

So is there any way to solve this and make the print look exactly like the pdf file? I know I can design everything again in PS, but that would take too much time and I need it for tomorrow =(

Any help greatly appreciated.
