I’m a print broker not to graphic design savvy, but savvy enough. Client provided a packaged InDesign file in which we sent back a print ready pdf for them to review/approve. They complained saying an image on the back cover appeared to be the “negative image” of the pic, but it looked ok to me. They said the viewed the pdf via Word, so I assumed that was the issue. So I submitted the file to the print vendor & they provided a pdf proof and all looked ok to me. Just got the publication and the image was printed as a “negative” image. How is this possible? Why would it look good to me, at least on my computer. I’m afraid the vendor will say to them it looks like a negative image on their side. Worried that I can’t trust a pdf now. Help! I need to get a grasp of this issue and figure out why it happened.
Thanks for your help!!!
