Traditional offset printing, gravure printing, relief printing and screen printing all belong to the category of plate printing, which will be discussed later in this chapter. The rise of lithography technology has also brought a certain impact to the traditional printing industry. Lithography technology is different from the traditional printing production process, including photoelectric imaging printing, laser imaging printing, inkjet printing, magnetic printing, heat transfer printing and so on. Prepress is similar to digital prepress, but does not need to output film or plate. Files can be output directly to digital printing devices. With online or offline binding equipment, the production process can be completed. It has a wide range of applications, including advertising, monthly reports, a small number of books, posters and proofs.

平版印刷有很多特点，一般来说，有以下几点：-无胶片和印版-个性化印刷-按需印刷-无需印刷设备时间-套印非常准确-没有专业印刷操作员-可以在线工作。

Lithography has many characteristics. Generally speaking, there are the following points: - no film and plate - personalized printing - on-demand printing - no printing equipment time - overprint is very accurate - no professional printing operator - can work online.

无纸印刷与传统的胶印、凹版印刷、凸版印刷和丝网印刷有很大不同。传统印刷必须依赖于特定的图像载体，如印刷版或丝网版，而印刷版的图像和图像是不可改变的。无版印刷，顾名思义，就是为了摆脱印版的局限，利用计算机软件，将图像图形转换成电子格式，直接或间接地印在基材上。凹版印刷在发展之初，主要用于企业的快速印刷、短印刷和内部文件等业务。目前，无版印刷技术有了很大的进步。印前设备的性能和印刷质量与传统胶印非常接近。目前已广泛应用于商业印刷领域。

Paperless printing is very different from traditional offset printing, gravure printing, relief printing and screen printing. Traditional printing must rely on a specific image carrier, such as printing plate or screen plate, and the image and image of printing plate can not be changed. Plate less printing, as the name suggests, is to get rid of the limitations of the printing plate, use computer software to convert images and graphics into electronic format and print them directly or indirectly on the substrate. At the beginning of its development, gravure printing was mainly used for fast printing, short printing and internal documents. At present, the technology of plate less printing has made great progress. The performance and printing quality of prepress equipment are very close to that of traditional offset printing. At present, it has been widely used in the field of commercial printing.

无版印刷工艺比传统印刷工艺更具工艺性和环保性。因为所有的印前处理，包括图像和构图，都是在电子平台上完成的，不需要使用胶片，大大减少了对冲洗液、冲洗液等化学液体的需求，直接减少了对环境和生态的污染。大多数无纸印刷不需要使用液体墨水，而是使用干墨粉。喷墨设备使用液体墨水，一般是水溶性墨水，很容易通过一个非常薄的喷墨喷嘴喷到基材上。商业印刷中使用的无纸印刷设备按成像技术进行分类，包括静电印刷、喷墨印刷、磁成像印刷、电离子印刷等。接下来，深圳宝安博林印刷有限公司介绍了成像技术的分类

The plateless printing process is more technologically and environmentally friendly than the traditional printing process. Because all prepress processing, including image and composition, is completed on the electronic platform, there is no need to use film, which greatly reduces the demand for developing fluid, developing fluid and other chemical liquids, and directly reduces the pollution to the environment and ecology. Most paperless printing does not require liquid ink, but dry toner. Inkjet equipment uses liquid ink, generally water-soluble ink, which can be easily sprayed onto the substrate through a very thin inkjet nozzle. Paperless printing equipment used in commercial printing is classified according to imaging technology, including electrostatic printing, inkjet printing, magnetic imaging printing, electro-ionic printing, etc. Next, Shenzhen Bao'an Bolin Printing Co., Ltd. introduced the classification of imaging technology
