做好印刷厂的颜色处理!

来源:   日期:2021-04-06

印刷技术是图文信息的复制技术,印刷品是传播科学学问常识的信息载体。印刷品是文字、图像的载体,信息传递的工具,学问传播的媒介,艺术作品的再现,美化威尼斯官方网站平台的方式,商品宣传的手段,逐渐成为大家生活中不可缺少的一部分。下面和棋牌游戏平台一起来看下印刷的两大特性:
Printing technology is the reproduction technology of graphic information, and printed matter is the information carrier of spreading scientific and cultural knowledge. Printed matter is the carrier of words and images, the tool of information transmission, the medium of cultural communication, the reproduction of art works, the way of beautifying packaging and the means of commodity publicity, which has gradually become an indispensable part of our life. Let's look at the two characteristics of printing with Jinan printing factory:
1、复制性
1. Replicability
印刷业作为一种特殊的加工工业,其任务是复制原稿中的图文信息,原稿是印刷作业的依据和基础。从信息角度上看,印刷过程是模拟信息的数字化(A/D转换)-数字信息处理-数字信息模拟再现(D/A转换)的过程。
As a special processing industry, the task of printing industry is to copy the graphic information in the original, which is the basis and foundation of printing operation. From the perspective of information, printing process is a process of analog information digitization (A / D conversion) - digital information processing - digital information analog reproduction (D / a conversion).
2、艺术性
2. Artistry
印刷术是技术与艺术的结晶,复制原稿的过程,也是艺术加工的过程。印刷从业人员应具有一定的艺术赏析能力,需准确的把握原稿的艺术特点和风格,采用恰当的复制手段和工艺方法,再现原稿的魅力,并通过图像处理增加其艺术表现力。
Printing is the crystallization of technology and art. The process of copying the original is also the process of art processing. Printing practitioners should have a certain ability of art appreciation, accurately grasp the artistic characteristics and style of the original, adopt appropriate copying means and process methods, reproduce the charm of the original, and increase its artistic expression through image processing.
印刷厂随着社会的发展,发展空间在不断的提升,当大家在印刷的时候颜色的地位是非常高的,而工作人员需要具备颜色处理的方法,下面就给大家先容一下做好颜色的处理:
With the development of society, the development space of the printing factory is constantly improving. When we are printing, the position of color is very high, and the staff need to have the method of color processing. The following is to introduce how to do a good job in color processing:
一、印刷过程中
1、 During the printing process
1、出现墨色不实的原因很多,其涉及的因素也很多,包括纸张的性能、油墨的性能、印版的质量、印刷橡皮布 的质量、印刷压力、印刷机的性能和印刷工艺等方面。
1. There are many reasons for false ink color, including paper performance, ink performance, printing plate quality, printing blanket quality, printing pressure, printing press performance and printing process.
2、如果纸张、油墨的性能稳定,印版制作质量满足了印刷要求,印刷机工作性能相对稳定的话,还是出现了墨色印刷不实现象,其主要产生的原因就是印刷压力的问题了。
2. If the performance of paper and ink is stable, the quality of printing plate meets the printing requirements, and the working performance of the printing press is relatively stable, the ink printing is not true. The main reason is the printing pressure.
二、在平版胶印过程中常会碰到颜色印不实的现象,在印刷品上主要表现为印品实地部分有斑点或发虚,图文或线条残缺不全,图像的阶调层次再现性差或网点丢失。
2、 In the process of offset lithography, we often encounter false color printing. On the printed matter, it is mainly manifested as spot or void in the field part of the printed matter, incomplete graphics and lines, poor reproducibility of image gradation or dot loss.

三、在胶印中
3、 In offset printing
1、压力的大小直接决定了印刷过程中油墨的转移,如印刷过程中出现局部的压力不均,将导致印刷墨色的不实。
1. The size of the pressure directly determines the transfer of ink in the printing process, such as local uneven pressure in the printing process, will lead to the printing ink color.
2、由于橡皮滚筒安装在印版滚筒和压印滚筒之间,橡皮布上的每个微小单元每旋转一周,都要分别和两个滚筒各接触一次。
2. Because the rubber cylinder is installed between the plate cylinder and the impression cylinder, each tiny unit on the blanket has to contact with the two cylinders respectively once every rotation.
3、油墨的转移就是橡皮布压缩变形的结果,橡皮布的压缩变形是产生压力的根本保证,因此,压力的大小及均匀程度与胶印印刷用的橡皮布有着直接联系。
3. The transfer of ink is the result of blanket compression deformation, which is the fundamental guarantee of pressure. Therefore, the size and uniformity of pressure are directly related to the blanket used in offset printing.
4、其受力是周期性变化的,正是由于橡皮布受力的周期性变化,会导致橡皮布产生内耗,导致橡皮布的老化,影响印刷压力的均匀性,可能导致橡皮布的报废。
4. The stress changes periodically. It is precisely because of the periodic change of the stress of the blanket that the blanket will produce internal friction, lead to the aging of the blanket, affect the uniformity of the printing pressure, and may lead to the scrap of the blanket.
5、橡皮布在压印力的作用下,具有很好的将印版图文部分的油墨传递到承印物表面的能力,即受墨和释墨能力,但是橡皮布的老化会改变这种油墨传递的能力,也会导致墨色不实的现象。
5. Under the effect of the impression force, the blanket has a good ability to transfer the ink of the graphic part of the printing plate to the surface of the substrate, that is, the ability to receive and release the ink. However, the aging of the blanket will change the ability to transfer the ink, which will also lead to the phenomenon of false ink.
6、包覆在滚筒上的橡皮布,受到张紧力和压力的作用,随着滚压次数的不断增加,橡皮布压缩变形的应力积累会变得硬挺,失去原有的柔软性和高弹性,甚至表面会出现光亮或龟裂的痕迹,从而导致压力的局部不均匀。
6. The blanket wrapped on the drum is under the action of tension and pressure. With the increase of rolling times, the stress accumulation of blanket compression deformation will become stiff, lose its original softness and high elasticity, and even appear bright or crack marks on the surface, leading to local uneven pressure.
