Much of the success of Color+ lies in Sericol’s proprietary Micro V ultrafine dispersion technology, originally developed for UV-curing inkjet systems.The tolerance of low viscosity ink is critical: to prevent clogging the print heads on a digital press, the particulate in the ink has to be especially fine.
The pigments in Color+ are dispersed to less than one micron in size.

The unique manufacturing process meticulously refines pigment particles, from an initial size of around 50 microns to below one micron in size. To put that in context, particles start about the size of a grain of salt and finish up several times smaller than a human cell. The fineness of grind and dispersion of pigments in the ink have a profound effect on colour and quality as well as on the print heads themselves.
On the one hand large quantities of pigment in the formulation offer full vivid colours,
while pigment that is too coarse will make the print heads susceptible to clogging.
As part of Sericol’s performance testing, the company examined the quality of competing products - only one out of ten competitor products managed to pass Sericol’s own filter tests.
