Together with compass, gunpowder and papermaking, it is called the four great inventions of ancient China.

Color printing

  在同一张纸上用不同颜色的印版印刷,彩色丝网的效果将文字、图片、照片等原稿通过制版、油墨应用、压印等工序,使油墨转移到纸张、织物、皮革等材料的表面,批量复制原稿内容的技术。

  现在彩色印刷普遍采用平版印刷。

  Nowadays, color printing is generally used in lithography.

  光刻有时也被称为化学印刷,这意味着印刷的图像与印版在同一平面上。它是基于“油和水不混合”的原则印刷。这种彩色印刷是通过机械或手工将图像印在石头或金属表面上,然后对其进行化学处理,使图像的一部分是嗜墨的,其余空白部分是嗜墨的。在印刷技术中,只有喜爱油墨的部分才会被转移到纸张上,从而产生印痕。照相印刷、影印和胶印都是平版印刷。

  Photolithography is sometimes called chemical printing, which means that the printed image and plate are on the same plane. It is based on the principle of "oil and water do not mix". This kind of color printing is to print the image on the stone or metal surface by machine or hand, and then carry out chemical treatment on it, so that one part of the image is inky, and the rest of the blank part is inky. In printing technology, only the part that likes ink will be transferred to paper, so as to produce impression. Photoprinting, photocopying and offset are all lithography.

  分色处理:分色处理是对原稿进行数字化扫描,将原稿分为红、绿、蓝三部分。

  Color separation processing: color separation processing is a digital scanning of the original, which is divided into three parts: red, green and blue.

  网孔:印刷油墨不混合。因此,一次只能在纸上印刷一种颜色的墨水。不同的颜色紧密地印在一起,产生了一种视觉上的融合,给观众一种不断调整图像的概念。要使颜色彼此分离,可以用屏幕分割来达到这个目的,所产生的点也称为半色调或网格色调。

  Mesh: printing ink does not mix. Therefore, only one color of ink can be printed on paper at a time. Different colors are closely printed together, resulting in a visual fusion, giving the audience a concept of constantly adjusting the image. To separate colors from each other, you can use screen segmentation to achieve this goal. The resulting dots are also called halftones or grid tones.
