印刷薄纸需要调控的外部因素有哪些?

众所周知,厚纸印刷和薄纸印刷有着很大差别。因此,在实际操作时,应根据需求选择合适的纸张类型。下面济南书刊杂志印刷给大家普及一下印刷薄纸需要调控的外部因素,希望对大家有所帮助!
As we all know, there is a big difference between thick paper printing and thin paper printing. Therefore, in actual operation, the paper type should be selected according to the demand. The following Jinan books and magazines printing to everyone to popularize the external factors that need to be regulated and controlled for printing thin paper, I hope to be helpful to you all! 
首先,要掌握影响薄纸印刷的环境温湿度。印刷薄纸时,更好现裁现用,这样可更大限度地减少纸张与空气的接触时间。如果所裁纸张(包括半成品)没有立即使用,应当用保鲜膜或拉伸膜把纸张缠绕起来,防止其因接触空气而变形。为了保证纸张内部含水量的合理(6%左右),还应注意纸张的堆放位置,不宜靠墙、靠窗、靠水龙头、靠暖气(冬天),更不可露天放置,以免过于干燥而破坏纸张含水量的合理,造成纸张翘曲不平等后果。
First of all, we should master the environmental temperature and humidity that affect thin paper printing. When printing thin paper, it is better to cut it now, so as to minimize the contact time between paper and air. If the cut paper (including semi-finished products) is not used immediately, the paper should be wrapped with a fresh-keeping film or stretching film to prevent it from deforming due to air contact. In order to ensure that the moisture content of paper is reasonable (about 6%), we should also pay attention to the stacking position of paper. It is not suitable to place paper by wall, window, tap, heating (winter), and not open-air, so as to avoid excessive drying and damage the rationality of moisture content of paper, resulting in unequal results of paper warping.
其次是在掌握薄纸印刷影响因素的基础上,针对性地对纸张进行合理调控,可采取以下方法解决。
Secondly, on the basis of mastering the influencing factors of thin paper printing, the paper can be reasonably regulated and controlled, which can be solved by the following methods.

(1)除湿法:利用空调的除湿功能去除室内空气中多余的水分,就可以有效达到除湿的目的。印刷车间的标准环境为温度20℃左右、相对湿度55%~65%RH。

(1) Dehumidification: The purpose of dehumidification can be effectively achieved by utilizing the dehumidification function of air conditioning to remove excess moisture in indoor air. The standard environment of printing workshop is about 20 ~65% RH and 55% RH.
(2)砸页法:如果纸张印刷后出现卷曲现象,可用砸页法加以解决,将所切印张翻身,用手工“砸纸”的方法把卷曲的印张敲砸出许多折线,利用折线与折线之间产生的支撑力,强行改变弯曲的印张,使之相对平整。
(2) Page smashing method: If the paper curls after printing, it can be solved by page smashing method, turning all the printed sheets over, using manual "paper smashing" method to smash the curled sheets out of many folded lines, using the support force between folded lines and folded lines, forcibly changing the bended sheets to make them relatively flat.
(3)晾纸法:晾纸法是利用晾纸机将裁切后的纸张或者没有裁切的纸张通风吹晾,使纸张内部的湿度和空气湿度保持相对平衡,使纸张的含水量符合印刷要求并保持稳定,保证其在印刷和印后加工中不易变形。这样既可提高印刷质量,也能给印后加工减少很多麻烦。
(3) Paper-drying method: The paper-drying method is to use the air-drying machine to air the cut paper or the uncut paper, so as to keep the relative balance of moisture and air humidity in the paper, make the moisture content of the paper meet the printing requirements and maintain stability, and ensure that it is not easy to deform in printing and post-printing processing. This can not only improve the quality of printing, but also reduce a lot of trouble for post-press processing.
