                香港马报免费资料最新:精准高手论坛免费资料中出现掉版现象的原因是什么?

                  在相册打印中,由于种种原因会导致打印出来的现象。造成这一现象的原因有很多,如何解决这一现象是非常关键的。今天小编就跟大家分享一些方法,希望能对大家有所帮助!

                  In album printing, printing will be caused by various reasons. There are many reasons for this phenomenon. How to solve this problem is very important. Today, Xiaobian will share some methods with you, hoping to help you!

                  造成相册印刷缺版现象的原因之一

                  One of the reasons for the lack of plate in album printing

                  1、油墨粘度

                  1. Ink viscosity

                  胶印过程如果油墨的粘度太大,除了导致油墨转移困难,而且还将油墨层,中间的情况,这样剩下的油墨层是不够的,其结果是使板块的文本部分板块裸穿,出现的板。

                  In the offset printing process, if the viscosity of the ink is too large, it will not only cause the difficulty of ink transfer, but also cause the ink layer, the middle situation, so that the remaining ink layer is not enough, the result is to make the text part of the plate plate plate naked through, resulting in the plate.

                  二、润班溶液ph值

                  II. PH value of runban solution

                  如果酸性太强就会腐蚀印版砂,破坏印版的亲水性层,这很容易使印文和文字在压印过程中脱落。一般情况下,润版液的PH值在5左右。

                  If the acid is too strong, it will corrode the printing plate sand and destroy the hydrophilic layer of the printing plate, which is easy to make the print and text fall off in the process of printing. Generally, the pH value of the fountain solution is about 5.

                  专辑印刷缺版现象的第二个原因

                  The second reason for the lack of album printing

                  3.压力

                  3. Pressure

                  如果油不朱辊上的印版压力太小,油不朱在印版上不敷敷,油不朱层的调动,图文和图文部件都会磨损。

                  If the plate pressure on the ink roller is too small, the ink is not enough on the plate, the adjustment of the ink layer, graphics and text components will be worn.

                  如果油不朱辊与印版之间的压力过大,就会加速印版图文的磨损,使印版上的砂粒被损坏,印版上的毛坯脏了,印版上的图文部分毛了,导致印版出现问题。

                  If the pressure between the ink roller and the plate is too large, it will accelerate the abrasion of the plate image and text, so that the sand on the plate is damaged, the blank on the plate is dirty, and the image and text on the plate is rough, which leads to the problem of the plate.

                  4、墨辊

                  4. Ink roller

                  油不朱辊老化后,亲水性可增强,而促油不朱性能变弱,转移油不朱性能变差。在机械轧制过程中,形成“油中水”型油墨乳化液,导致印版和印刷文字部分印版油污。

                  After the aging of the ink roller, the hydrophilicity can be enhanced, while the ink promoting performance becomes weak, and the ink transfer performance becomes poor. In the process of mechanical rolling, the emulsion of "oil and water" type ink is formed, which results in greasy dirt on the plate and the printing text.
