Unmatched ink drying speed restricts efficiency of high-speed color printing production. Too slow ink drying will cause ink smudging, sheet adhesion and pattern contamination after paper stacking, requiring long standing time to dry naturally, which greatly reduces printing output and occupies workshop storage space. Excessively fast ink drying leads to incomplete ink leveling, surface cracking, poor color fusion and faded printing layers, lowering printing delicacy. Paper surface pore structure, surface sizing permeability and surface chemical activity are core factors controlling ink absorption and drying rhythm. Most printing factories add drying accelerator on printing equipment, which increases printing auxiliary cost, corrodes printing rollers, and causes toxic volatile substance emission. Improving paper inherent ink drying adaptability is the most economical and efficient improvement way. Shandong Ludao Energy Technology Co., Ltd. adjusts paper surface micro-pore structure and surface activity scientifically, realizes controllable and uniform water-based and oil-based ink drying speed. It ensures full ink leveling before curing, avoids smudging and cracking, shortens printing interval stacking time, improves high-speed printing efficiency, reduces printing auxiliary consumption, and fits full-automatic color printing assembly line production.
