印刷时不干胶的墨色稳定定性如何提高?

一、开印前,要凭经历做好预调工作:
1. Pre-printing work should be done according to experience:
首先,依据打样稿或印幅员文面积,粗略调理各色组墨斗的下墨量。在配有墨色遥控系统的机器上,这项工作更易完成。对此应有八成以上的预算,不要在印刷时边印边大范围地调整墨量,以免形成很大的色差。
Firstly, according to the area of proofing manuscript or printing sheet, roughly adjust the ink quantity of each color group ink bucket. On machines equipped with ink remote control system, this work is easier to accomplish. There should be more than 80% of the budget for this. Do not adjust the amount of ink on a large scale when printing, so as to avoid a large color difference.
其次,依照消费工艺单的请求和该产品的特性,预先调理好飞达、收纸、油墨性能、压力大小等各个环节,防止在正式印刷时手忙脚乱。其中,确保飞达牢靠、连续、稳定地输纸是更重要的。有经历的操作人员都是先依据纸张的幅面、厚度,预先调整好吹气、吸气、压脚、压簧、压纸轮、侧规、前规等,理顺各部件之间的运动配合关系,确保飞达流利地输纸,防止因飞达打顿而形成墨色深浅不一。这里倡议,有经历的工人师傅能够对飞达停止预先调整。
Secondly, according to the requirements of the consumption process sheet and the characteristics of the product, we should pre-regulate Feida, paper collection, ink performance, pressure and other links to prevent confusion in formal printing. Among them, it is most important to ensure that Feida feeds paper firmly, continuously and steadily. Experienced operators are based on the size and thickness of the paper, pre-adjusted air blowing, inspiration, foot pressing, spring pressing, paper wheel, side gauge, front gauge, etc., to straighten out the relationship between the movement of various components, to ensure that Feida fluent paper delivery, to prevent the formation of ink shades due to Feida Datong. It is advocated here that experienced workers can stop pre-adjusting Feida.
此外,还要针对该印品的用纸质量好坏、图文面积大小,事前对油墨的黏度、活动性、枯燥性等恰当调理,以进步其印刷适性,确保印刷正常停止,不能因经常停机清洗橡皮布和印版上的纸毛、墨皮而形成墨色深浅不一。假如到了印刷中途再参加各种撤黏剂、调墨油,呈现颜色偏向是肯定的。
In addition, according to the quality of the paper used, the size of the graphic area, the viscosity, activity and dullness of the ink in advance, proper conditioning should be made to improve the printing suitability and ensure the normal stop of printing. The ink shade can not be different because of frequent shutdown to clean the paper fur and ink on the rubber cloth and the printing plate. If you go to the middle of the printing process to participate in a variety of viscose remover, toner, color bias is affirmative.
总之,将开机前的预调工作做好,就能够大大降低正式开印后的毛病,机长也才有时间和精神集中看好墨色。

In a word, if we do well the pre-adjustment work before starting, we can greatly reduce the defects after the official printing, and the captain has the time and spirit to concentrate on the ink color.

二、正确调理水、墨辊压力
2. Correctly adjusting the pressure of water and ink rollers
在印刷过程中,印幅员文局部必需得到时断时续、平均适量的油墨,才干取得墨色分歧的印品。因而,墨辊与墨辊之间、墨辊与印版之间,必需坚持恰当的接触和滚动关系,以完成油墨的良好传送。假如这项工作做得不细致,不正确,墨色就不会坚持分歧。因而,每次装置水、墨辊时,都坚持采用轧墨杠的办法来逐一调理它们之间的压力,而不用塞尺试拉力的传统办法,由于后者因各种人为要素招致的实践误差较大,在多色、高速机上更要禁用。至于轧墨杠的宽度,普通以4~5mm为宜。先调理传墨辊与串墨辊之间的压力,再调理着墨辊与串墨辊、印版滚筒之间的压力,更后再调理传水辊、靠版水辊、串水辊、中间辊互相之间的压力,还有靠版水辊与印版滚筒之间的压力,这几个水路之间的墨杠以6mm为宜。
In the process of printing, it is necessary for the part of the printer to get intermittent and average amount of ink in order to obtain the printing with different ink colours. Therefore, the proper contact and rolling relationship between ink rollers and ink rollers and between ink rollers and printing plates must be adhered to in order to complete the good transmission of ink. If this work is not done carefully and correctly, ink will not insist on differences. Therefore, when installing water and ink rollers, we always stick to the method of rolling ink bars to regulate the pressure between them one by one, instead of the traditional method of pulling force test by plug ruler. Because the latter has large practical errors caused by various human factors, it should be banned on multi-color and high-speed machines. As for the width of the ink bar, 4-5mm is usually the best. First adjust the pressure between the ink transfer roll and the ink string roll, then adjust the pressure between the ink roll and the ink string roll, the printing plate roll, and finally adjust the pressure between the water transfer roll, the ink plate roll, the water string roll and the intermediate roll, as well as the pressure between the plate plate plate water roll and the printing plate roll. The ink bar between these water routes should be 6 mm.
