White Ink and Its Creative Uses

Posted by:

Digital printers have traditionally used some version of a CMYK ink set to reproduce colors (some use additional CMYK Light colors for greater subtlety of tone, or chromatic green, orange or red for increased vibrancy).

These color sets are perfect for printing on white media, but what if your media was clear, black or colored? It would be impossible to correctly render the colors, and what if a design required white ink on these substrates?

Fortunately, UV curable digital white ink has matured as a technology. It was a difficult technical problem to solve: white ink pigments must be heavy enough to produce opaque coverage, but not clog ink systems and sensitive print heads. Even with sophisticated recirculating ink systems, printers equipped with white ink channels require regular and consistent operation. SignCenter prints 100’s of thousands of square feet of white ink a year on our OCE and Vutek Printers. Many of the creative options are listed below.
