纸张的白度与吸收性.纸张的白度是印刷色彩鲜艳的基础.理想的纸张能够反射接近全部的色光,而含灰、黑、偏青、偏红或其他偏色的纸张会吸收部分入射色光,导致印迹的色相、明度和饱和度都会受到影响,更终表现为色彩的差异.这相当于在油墨当中加入了部分的其他油墨,表现出色墨的不纯,从而给人一种发暗、浑浊和偏色的感觉.

Whiteness and absorbent paper. The whiteness of the paper is the basis of bright color printing. The ideal paper can reflect nearly all the shade with gray, black, blue, red or other partial partial color paper will absorb part of the incident light, resulting in hue, lightness and saturation of imprinting will be affected. For the final performance of the color difference. This is equivalent to add other parts of the ink in the ink, the ink performance is pure, which gives people a dark, muddy and color feeling.

油墨传递和滚压过程.色墨在涂布时墨斗和墨辊不清洁,混有色墨,势必造成偏色,同样造成色彩的不鲜艳.因此,在换色时,务必把墨斗、墨辊和水辊清洗干净,特别是深色换浅色时更要注意清洁.

The ink transfer and rolling process. When coating and ink color ink roller not clean, mixed colored ink, is bound to cause partial color, can also cause the color is not bright. Therefore, the color change, make sure the ink rollers and water roller, clean, and pay special attention to cleaning more light. Dark change

通常的做法是,深色墨清洗洁净后,再铲上部分即将使用的浅色墨,打匀一段时间后,再进行清洗.对于双色机和多色胶印机,尤其是上下机组共用一个压印滚筒的设备,更要注意混色情况的发生.一旦混色肯定会造成偏色,致使色墨不鲜艳.

Usually it is dark clean, then shovel will use the light coloured ink, beating well after a period of time, then wash. For double color and multi-color offset press, especially on the unit share an imprint of equipment, more attention should be paid to color mixing occurrence. Once the color will cause partial color, the color ink is not bright.

油墨过度乳化和加放添加剂.传统的胶印印刷方式,主要还是依靠水墨平衡来完成印刷过程的.根据油墨的传递过程分析,油墨的乳化是不可避免的.但过度乳化后的油墨,会造成印品色泽减淡、变陈旧等现象,致使色彩鲜艳度降低.

Ink excessive emulsification and add additives. The traditional offset printing ink balance, mainly rely on to complete the printing process. According to the analysis of the transfer process of the ink, the ink emulsion is inevitable. But excessive emulsified ink will cause printing color dodge, old phenomenon, resulting in reduced brightness.
