When I do a print to PDF of separations of a Color Spot file, the PDF is not correct and leads to misbehaviours of my Riso printer.
A little example of a drawing with 2 spot colors (Red and Blue), 2 vector shapes and 6 monochrome bitmaps in different shades of the Red and the Blue :
A print preview in CorelDraw of the Red printout is correct.
Only objects with Red are on that page :
After printing this to PDF (using CutePDF Writer), the PDF looks good:
But when looking closer to this PDF, the PDF is not correct.
One can see that:
1) all the bitmaps are transformed and sliced into hundred of bitmap lines:
2) Worse, all the Blue objects are also present on the Red page but a White color (not even transparent):
(These 2 screenshots are from a re-import of the PDF file into Corel Draw)
Those white objects and bitmaps are confusing the printer and leading to misbehaviour.
Is there a way produce better PDFs ?
What print driver are you using?
I've tried also with Wondershare PDF Element, but this is the same behaviour. Even after the PDF optimization?.This is really something done by CD.
Obviously there is a problem with PDF print driver, try a true Adobe PDF driver.
Not sure this is something wrong with the PDF print driver as I've been able to reproduce the issue with other PDF print drivers. And the Adobe one is just unaffordable .
Anyway, when I select in CD print options the Postcript Compatibility to "Postscript 3" instead of "Level 2" the result is far better. Still some white objects but not longer sliced bitmaps. So I guess this is the solution. I'm heading the printshop .
Thanks for your help.
