Reply To: Missing colors when printing !

Can you take a screen shot in InDesign with your Swatches Pallette? Make sure you are adding unnamed colors, and converting all Spot Colors to Process. (Assuming this is a process job). Otherwise, you should check to see if there are any Overprint settings of vector art in both InDesign and Illustrator (both with Selection and Direct Selection tool).

Otherwise, it could be a PostScript error. PDFs should be saved with x1a standard. Raster effects, especially gradients and spot colors can cause big printing problems.

Did your printer offer a printed proof? It’s not normal to print 5,000 copies without a customer-approved proof.
