印刷是将文字、图画、照片等原稿经制版、施墨、加压等工序,使油墨转移到纸张、织品、皮革等材料表面上,批量复制原稿内容的技术。印刷有多种形式分为:传统胶印,丝网印刷,数码印刷等。孔版印刷与凸版印刷、凹版印刷、平版印刷并称现代四大印刷术,印刷厂是设计,打样、制版、印刷、装订、包装、运输,为一体的综合机构。当然比较重要的是印刷厂必须有印刷设备才可称做是印刷厂,而印刷机比较为重要,印刷机有单色双色的,有四色八色的,按规格分有8开机、4开机、半开机和全开机,一些简单的印刷还可以用丝网印刷,只需个丝网即可完成印刷,但是效果不比大机印刷好看。

印刷业务之种类不同,用途亦异。如书刊印刷 、新闻印刷、广告印刷等。

书籍杂志之印刷,以往采用凸版印刷。

新闻印刷:以往尽用凸版轮转机印刷,因其快速而印量大也。近为适应彩色需要,改用平版或照相凹版轮转机印刷。

广告印刷:含彩色图片、画报、海报等在内,大部分采用平版印刷,间或亦有用凸版,凹版或孔版印刷者。

文具印刷:如信封、信纸、请帖、名片、帐册、作业簿本等,必须成本低廉、大量印刷,因而品质较次,故多以凸版印刷为优先考虑。

Printing is a technique that transfers ink to the surface of paper, fabrics, leather, and other materials and replicates the contents of the original manuscript in bulk. Printing has a variety of forms: traditional offset printing, screen printing, digital printing and so on. Portable printing and relief printing, Gravure printing, and lithography are also known as the four modern printing techniques. The printing factory is a comprehensive institution that is designed to sample, plate making, printing, binding, packaging, and transportation. Of course, the most important thing is that the printing factory must have printing equipment before it can be called a printing factory. The printing press is the most important. The printing press has a monochrome, two-color, four-color, and eight-color, and it has 8 boot, 4 boot according to specifications., semi-boot and full-boot. Some simple printing can also be printed using screen printing. Only a screen can be used to complete printing, but the effect is no better than that of large printing.
The types of printing business are different and the uses are also different. Such as book printing, news printing, advertising printing and so on.
The printing of books and magazines used to be letterpress printing.
Press printing: In the past, we used to print with a relief wheel, because of its rapid and large printing volume. In order to meet the needs of color, use lithography or photo-concave rotary printing.
Advertising printing: Including color pictures, pictorials, posters, etc., most of them are printed in lithography, and sometimes they are printed in Letterpress, Gravure, or hole.
Stationery printing: such as envelopes, letter papers, invitations, business cards, account books, job books, etc., must be cheap and printed in large quantities, so the quality is inferior, so letterpress printing is preferred.
