1results about How to "Speed up printing" patented technology

This application provides an ink formulation and process for improving the stability of gravure proofing production, relating to the field of printing technology. The ink formulation provided in this application includes 60-70% binder, 10-18% pigment, 0.5-1% defoamer, 1.5-3% filler, 1-3% alcohol solvent, and water as the balance. The filler is silane coupling agent-modified calcium carbonate; the binder is an aqueous acrylic emulsion or polyurethane emulsion with a mass ratio of (30-85):(15-70). This polyurethane emulsion is prepared by reacting aliphatic diisocyanate and L-lysine diisocyanate with a polyol, and a 3-methoxy-4-hydroxymandelic acid chain extender is introduced. Using this ink formulation for printing avoids the low production efficiency and increased production costs caused by repetitive labor, achieving stable gravure printing production. The printed products have uniform and stable color, high adhesion, and good durability.
