Xerox Corp. has received “good de-inkability” certifications for its digital color production systems from the International Association of the Deinking Industry (INGEDE). The ratings were given to the Xerox iGen4, 700 Digital Color Press and Color 800/1000 Presses.
INGEDE, a globally recognized association made up of leading European manufacturers and paper mills, conducts a widely accepted, standardized test to identify the types of printed paper products that have the best recyclability when they are deinked.
The “good de-inkability” rating means the production systems achieved high scores, more than 90 out of 100, in the evaluation of five parameters – luminosity, color, cleanliness, ink elimination and filtrate darkening.
Deinking refers to the removal of ultraviolet and electron beam printing inks – an important step in the paper recycling process. Inks that are not deinkable spoil the recycling process by either reducing the brightness of the pulp or by leaving ink specks on the recycled paper.
