印刷品墨层干燥不良对裱胶质量危害极大.影响墨层干燥的因素,除了有油墨的种类、印刷过程中催干剂的用量与类型及印刷、存放间的环境温湿度外,纸张本身的结构也相当重要。
The printing ink layer drying poor laminating quality harm. Factors affecting the ink layer dry, in addition to type, ink printing process and printing type and amount of drying agent, environmental temperature and humidity storage room outside, the structure of the paper itself is also very important.

如铜版纸与胶版纸其结构不同,则墨层的干燥状况亦有区别。无论是铜版纸还是胶版纸,在墨迹未完全彻底干燥时裱胶,对裱胶质量的影响均是不利的。

For example, the structure of the coated paper is different from that of the offset paper. Whether it is coated paper or uncoated paper, ink is not completely dry when the glue, the impact of the quality of the adhesive is unfavorable.

油墨中所含的高沸点溶剂极易使塑料薄膜膨胀和伸长,而塑料薄膜膨胀和伸长是裱胶后产品起泡、脱层的更主要原因。
The high boiling point solvent in the ink is very easy to expand and extend the plastic film, and the expansion and elongation of plastic film is the most important reason for the foaming and delamination of the product.
数码打稿,即在大批量印刷前,采用数码印刷机印刷一本,作为核对装订顺序、内容、设计效果、图片清晰度和颜色的确认。

数码打稿采用碳粉为原料,故颜色较为鲜艳,但颜色不稳定,同台机上午下午输出的同文件打稿颜色都可能有差别。
Digital proofing by carbon powder as raw material, the color is bright, but the color is not stable, the same morning afternoon with the machine output file may have different color proofing.
印刷效果与数码打稿相比,印刷颜色相对沉稳,细腻度和图片清晰度稍强于数码打稿,但因数码打稿颜色稳定性差,故在采用数码打稿为色样时,印刷颜色无法跟准数码打稿,一般印刷颜色与数码打稿有10%左右的色差。
The printing effect compared with digital proofing, printing color relatively calm, delicate degree and picture clarity than digital proofing, digital proofing color but because of poor stability, so in the use of digital proofing for color printing, color to quasi digital proofing, digital proofing general printing color and color of around 10%.
