| 目的 提出一种基于印刷品质量参数的橡皮布印刷适应检测及评价方法，以控制印刷品质量、提升橡皮布质量。方法 在相同检测条件下，使用进口(A, B, C)、国产(D, E, F)胶印橡皮布进行印刷，对印刷品密度、叠印率、色差、网点扩大及橡皮布超肩铁量等参数进行检测。结果 得到了所有橡皮布KCMY密度平均标准差为0.021左右，RGB平均叠印率为92%左右。A, C橡皮布KCMY平均色差大于5，其余橡皮布在4.78左右。B橡皮布KCMY 50%网点面积处平均网点扩大为7%，其余橡皮布在9.7%左右。A, B, C橡皮布印刷后减薄量为0.02 mm左右，其余橡皮布为0.05 mm左右。结论 国产、进口橡皮布油墨转移性、网点还原性均较好，A, C橡皮布的M, Y色彩还原性较差，D, E, F橡皮布回弹性较差。 |
| 英文摘要: |
| The work aims to propose a testing and evaluation method for rubber blanket printability based on the printing quality parameter, in order to control the printing quality and improve the rubber blanket quality. Under the same test condition, the imported offset blankets (A, B, C) and domestic offset blankets (D, E, F) were used for printing. The printing density, trapping, color difference, dot gain, over bearer and other parameters were tested. As a result, all blankets’ mean standard deviation of KCMY density was about 0.021, and the RGB mean trapping was around 92%. The KCMY mean color difference of blankets A and C was greater than 5, and that of the remaining blankets was around 4.78. The 50% KCMY mean dot gain of blanket B was 7% at the dot area, and that of the remaining blankets was 9.7% or so. The thickness reduction of blankets A, B and C were around 0.02 mm, and that of the remaining blankets was about 0.05 mm. In conclusion, the ink transfer performance and dot reducibility of domestic and imported blankets are good, the M and Y color reducibility of blankets A and C is poor, and the resilience of blankets D, E and F is poor. |
