Driven by the wave of digitalization, digital printing presses have become an important force in the printing industry, meeting the diverse needs of different fields and customers. There are many types of digital printing presses on the market, and there are many classification methods based on different standards.
According to the imaging principle, digital printing presses are mainly divided into two categories: electrostatic imaging and inkjet imaging. Electrostatic imaging digital printing presses use laser scanning to form an electrostatic latent image on the photosensitive drum, then adsorb toner, transfer the toner to the paper and solidify the image through the fixing device. This type of printing press has a fast printing speed, high clarity of text and lines, and is suitable for printing a large amount of text and commercial documents with high precision requirements, such as batch printing of documents in office scenes, and short-run printing of some books and periodicals. For example, HP’s Indigo series of digital printing presses are widely used in the global commercial printing field. With excellent color performance and stable printing quality, they have won the favor of many printing companies.
Inkjet imaging digital printing presses spray ink directly onto paper through a nozzle to form an image. According to different inkjet technologies, it can be further divided into continuous inkjet and on-demand inkjet. Continuous inkjet is a method in which the nozzle continuously ejects ink droplets, and the direction of the ink droplets is controlled by an electric field to achieve graphic printing; on-demand inkjet is a method in which the nozzle ejects ink droplets on demand according to image signals. Inkjet imaging digital printers have rich color expression and can present realistic photo effects. They are suitable for personalized photo printing, large-format poster production, and some packaging printing with high color requirements. Epson’s SureColor series of digital printers, with its high-precision inkjet technology and wide color gamut, excel in art printing, advertising production and other fields.
Based on the printing format, digital printers can be divided into small format, medium format and large format. Small format digital printers are usually used in offices or small printing shops, processing A4, A3 and other sizes of paper, suitable for printing daily documents, flyers, etc., with small size, easy operation and relatively affordable price. The printing format of medium format digital printers is generally around the size of the folio, taking into account certain production efficiency and flexibility, and is often used in commercial printing, such as product catalogs and brochures. Large-format digital printing presses are mainly used for the production of large-scale printed materials such as outdoor advertising and architectural renderings. The format can be several meters wide, which can meet the needs of large-scale display and publicity.
In addition, according to the application field, digital printing presses can also be divided into office type, commercial type and industrial type. Office type digital printing presses focus on document processing capabilities, with fast printing, scanning, copying and other multi-functions, suitable for daily office scenes. Commercial digital printing presses have high requirements for printing quality and production efficiency, and can meet various commercial printing needs, such as books, magazines, posters, etc. Industrial digital printing presses are mainly used in large-scale industrial production, such as packaging printing, label printing and other fields, with high speed, stability and high degree of automation.
Understanding the classification of digital printing presses on the market will help users with different needs to choose suitable equipment and promote the efficient development of the printing industry.
