Hello... Just wanted to see if anyone had any info on this issue... The background is blue with a white stroked box on top... the blue prints fine, so does the white, but when it gets to the white stroke area the blue becomes slightly darker. Once it gets past the white stroked box the blue returns to normal... I don't get it. It's happened before, but with no resolution. Thanks in advance for any help. I've included a photo to illustrate the problem.
