Knocked out in the shadows

As the image on the right demonstrates, unwanted white knockouts will appear in PDF documents with drop shadows if spots are converted to process. With Prinect Color Editor, it’s possible to pinpoint the problem by checking the colors and the overprinting properties of the objects in the PDF. In this example, an overprinting image with a CMYK value of 0% has been placed over a knockout spot color image in the “problem zone.”
