Printing from pdf inverts image colors
Hey!
I am in charge of designing id's for a company, and we tested the first design, but the plastic card print came out like this:


(I blurred the original for privacy reasons)
I exported the file to pdf, as required for printing with our HDP5000 Thermal Printer. (The pdf file looked just fine)
Everything else and other images on the id printed as they should:

Is there any setting I should check to make it print right, or is it the printer's fault?
Thanks,
Martin
