Review Summary
The Lysonic Quad black process uses four intensities of black ink in place of the normal CMYK colours in a standard Photo Realistic ink jet printer. By using simple colour curve adjustments in image software such as Adobe PhotoShop, stunning black & white images with tonal graduation to match traditional silver Halide printing can be produced.
All Lysonic Quad Black inks have an extremely long life without noticeable fade in average indoor display conditions. Lyson's own testing indicates that Quad Black prints exceed the display life of most traditional silver halide images. Independent testing has been carried out by Wilhelm Imaging Research, Inc
