| 中文摘要: |
| 在标准印刷条件下，使用GATF测试版在商业轮转上印刷轻涂纸，根据相对反差K与实地密度的关系，基于最小二乘法多项式拟合得到了回归方程，研究了商业轮转胶印的最佳实地密度。研究结果表明：墨层较薄时，则实地密度小，色彩平淡；墨层过厚会导致网点增大过度，印刷品暗调并级。 |
| 英文摘要: |
| GATF test digital file was printed by commercial web offset on light coated paper under standard printing conditions. According to the relation between relative contrast value K and solid density, based on least squares polynomial fitting equation, the best solid density of commercial web offset was studied. The results showed that the thinner layer of ink, the smaller value of solid density and the lighter color; too thick ink layers results in excessive dot gain, print dark level superposition. |
