Piezography MPS Glossy inks (Selenium and Warm Neutral) require the use of MPS Black shade 1 and Piezography Gloss Overprint.
The use of a Gloss Overprint completely eliminates bronzing and any trace of gloss differential. When properly applied it is impossible to tell where the ink ends and the paper begins.
It can also be used to significantly improve Canon, Epson and HP glossy black & white and color prints.
For supported printers in the Piezography family we can provide a Gloss Overprint curve that can be used in single channels or in situations in which an entire printer is devoted to Piezography Gloss Overprint.
