Wood Planks - D632 by ~AGF81 on deviantART. Eliminating YDB (Yucky Discolored Box) Syndrome. Eliminating YDB (Yucky Discolored Box) Syndrome by: Claudia McCue | December 3, 2006 Steve Werner has posted an excellent solution to the Dreaded White Box (DWB) syndrome, wherein you see white boxes around shadows and other transparency effects interacting with spot color content.
The answer, as Steve points out, is for your print service provider to turn on PostScript Overprint at the RIP. (And, for correct viewing in Acrobat, turn on Overprint Preview.) But there’s something similar to the DWB syndrome that occurs on many digital printers, from our in-house laser printers up to the big boys like the Xerox iGen3. Printer Linker.
