Kodak Proofing Software Matchprint Inkjet can print in Reverse or Surface mode on clear film proofing media. Idealsolution recently ran tests comparing both print modes with white ink on on the Epson Stylus Pro WT7900 white ink proofer. Using Kodak Matchprint Inkjet Clear Media 4 mil, spectrophotometer measurements were taken and a Kodak ColorFlow print comparison report was generated comparing the Reverse print mode to the Surface print mode. As indicated in the diagram below, Reverse print mode has greater ink density and a wider colour gamut than Surface print mode.

If you are after the best results for packaging mock-ups when printing with white ink on the WT7900 proofer using Kodak Matchprint Inkjet Clear Media 4 mil, it is recommended that proofs are produced using Reverse print mode.
