Hi There,

I'm getting problems printing result... I've got a highress image (7926x5009px, at 300DPI, with a FOGRA39 CMYK colorprofile on it.) When I'm reviewing this image in Overprint view i get jacked lines in certain areas. In CPU view that is not the case. The printing result is also with the jacked lines.. I can't find a solution on the internet, so the help of you guys would be nice!

Your PDF has considerably less resolution than the Effective Resolution of the image (689ppi). If I inspect the image in AcrobatPro the image resolution is 250ppi with a pixel dimension of 2681 x 1817—not enough for the high contrast details in an image like yours. Check your Export Compression settings and either turn off downsampling or set Downsampling to a higher resolution than 250ppi.

Hi @TIES DEN HARTOGH , By print do you mean you are printing directly from InDesign? Do you see the probelm if you Export to one of the default PDF/X presets and you zoom in?

Hi @rob day,
No, I meant printing by a press, they get a PDF that they print for me.
If I test your idea with a PDF (see attachment), you see the same problem at 100% (as we saw in the test). If I zoom in to 200/300%, you don't have that problem.
