Transparency problem

[xcelprint]

my customers pdf looked fine on monitor but when printing on our versant 80 the bounding box of a logo image (png file) printed only part transparent. Ideas please? Thanks

I have read that png will not print transparency because it is rgb? Not sure how to advise my customer to change his file.

PNG files are really meant to be used for the web. For print production you would see better results with a Photoshop PSD file.

I would reference this thread. It may help you with the transparency issue.

Thanks Joe and Priceline... we managed to get a printable file by flattening the pdf on the Fiery. The transparency issue went away, we had some slight color shifts, but customer was pleased. Thanks again for your help.

We also worked around the issue by opening the pdf in Photoshop and saving as a PS PDF. Printed fine but the file size was much larger.

That also rasterizes everything and your text and vector objects will output at whatever resolution you opened the PDF in Photoshop instead of at the output device resolution which is normally 2400 to 2540 resolution.

If you print the PDF to your Fiery it will flatten it on the fly usually with good results. You can also flatten the PDF in Acrobat Pro. Both choices are better than opening the PDF in Photoshop.

You can rip this file by APPE in fiery server to resolve the problem.

But only if your Fiery has APPE. Ours does not.
