The 42000PFX Epic Dallas Scarlet ink is formulated to maintain a long time standard color for Wilflex inks. It is designed to provide a very clean shade of deep red. To improve your overprint color strength, you can try making on press adjustments to increase the ink film thickness. Using a coarser mesh count, softer, more rounded edge squeegee and a less vertical print angle will all help increase ink film deposit.
Alternatively, we offer the 42270PFX Epic Super Drake Red and 40500PFX Epic Super Red inks that are formulated with more opacity. These inks will improve color strength of your overprints if you make no on press changes.
