Business card printing and membership card making Ink viscosity in business card printing and membership card making faster, rollers and plates after the ink friction heats gets smaller, on the rising of the ambient temperature, the viscosity of ink will drift away, this time using the innovativeink, with the temperature increase, decrease viscosity is referred to as a viscosity index of added value, that is, the viscosity index is a viscosity index of temperature-dependent, for example, at a low temperature solvent oil sludge formation, if you join methylmetacrylate and transfromer monosomic of multi-fault copolymer exclude this.

制卡和会员卡制作油墨的粘度在随制卡和会员卡制作速度的加快时，因墨辊与印版摩擦后油墨温度升高而变小外，当环境温度的上升后，油墨的粘度也会逐渐变小，这种在使用油墨时，随着温度的上升，其粘度下降的行为被称为粘度指数增加值，即粘度指数是表示粘度随温度变化的指标，例如，溶剂油在低温下形成淤浆时，如果加入甲基丙烯酸酯和极性单体的共聚物排除此类故障的发生。
