济南印刷厂怎么去做好颜色处理呢?

  印刷是一个比较繁琐的过程,包括了很多的步骤和工作,其中颜色处理问题是挺重要的一个方面,那么济南印刷厂怎么去做好颜色处理呢?
  Printing is a tedious process, including a lot of steps and work, among which the color treatment problem is a very important aspect, so how to do a good job in jinan printing factory color treatment?
  在印刷过程中
  In the printing process
  出现假墨色的原因很多,涉及的因素很多,包括纸张性能、油墨性能、印版质量、印刷橡皮布质量、印刷压力、印刷机性能和印刷工艺。
  There are many reasons for false ink, involving many factors, including paper performance, ink performance, plate quality, printing blanket quality, printing pressure, printing machine performance and printing process.
  如果纸张和油墨性能稳定,印版质量满足印刷要求,印刷机工作性能比较稳定,仍然存在不能实现油墨彩色印刷的现象,主要原因是印刷压力的问题。
  If the performance of paper and ink is stable, the quality of the printing plate meets the requirements of printing, and the working performance of the printing machine is relatively stable, there is still the phenomenon of color printing ink, the main reason is the problem of printing pressure.
  在平版胶印的过程中,经常会遇到假色印刷的现象。在印刷品上,主要表现为印刷品实心部分出现斑点或空洞,图形或线条不完整,图像色调水平再现性差或网点丢失。
  In the lithography offset printing process, often encountered the phenomenon of false color printing. In printed matter, mainly for printed matter solid part of spots or empty, incomplete graphics or lines, image tone level reproducibility is poor or dot loss.
  在胶印中
  In the offset printing
  济南印刷厂认为压力的大小直接决定了印刷过程中油墨的转移。如果在印刷过程中出现局部压力不均,会导致印刷油墨颜色不真实。由于橡皮布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转一圈都需要与两个滚筒接触一次。
  Ji 'nan printing plant that the size of the pressure directly determines the transfer of ink in the printing process. If there is local pressure imbalance in the printing process, it will lead to false printing ink color. Because the blanket drum is installed between the plate drum and the imprint drum, each tiny unit on the blanket needs to contact the two drums once every turn.
  油墨的转移是橡皮布受压变形的结果。橡皮布的压缩变形是压力的根本保证。因此,压力的大小和均匀性直接关系到胶印所用的橡皮布。其力周期性变化。正是由于橡皮布上受力的周期性变化,会引起橡皮布的内摩擦,从而导致橡皮布老化,影响印刷压力的均匀性,并可能导致橡皮布报废。
  Ink transfer is the result of blanket compression deformation. The compression deformation of blanket is the fundamental guarantee of pressure. Therefore, the size and uniformity of pressure is directly related to the rubber sheet used by offset printing. Its forces vary periodically. It is because of the periodic change of the force on the blanket, it will cause the internal friction of the blanket, resulting in the aging of the blanket, affecting the uniformity of the printing pressure, and may lead to the scrap of the blanket.
  橡皮布在压紧力的作用下,有很好的将印版图文部分的油墨转移到承印物表面的能力,即接受和释放油墨的能力,但橡皮布会改变墨水,传输的能力也会导致出现假墨色的现象。包裹在滚筒上的橡皮布受到张力和压力。随着轧制次数的不断增加,橡皮布压缩变形的应力积累会变得僵硬,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,造成局部受压不均。
  Blanket under the action of compression force, there is a good printing plate graphic part of the ink transfer to the substrate surface, that is, the ability to accept and release ink, but blanket will change the ink, the ability to transfer will also lead to the phenomenon of false ink. The blanket wrapped around the drum is subjected to tension and pressure. With the increasing number of rolling, the stress accumulation of blanket compression deformation will become stiff, lose the original softness and high elasticity, and even the surface will appear bright or cracking traces, resulting in uneven local compression.
  印刷厂随着社会的发展,发展空间在不断的提升,当我们在印刷的时候,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,更多内容就来网站www.xinfengyinshua.cn咨询!
  Printing plant with the development of society, the development space is constantly improving, when we are in the printing, the status of color is very high, and the staff need to have the method of color processing, more content to consult the website!
