Digital printing machines are classified into industrial digital printers and office digital printers according to their uses.

According to the size of its production capacity, digital printing machines can be divided into four categories:

1. Light-duty production digital printing machine: entry-level equipment engaged in digital printing production. The monthly production capacity is 150,000 to 300,000 pages (A4). Mainly single-sheet laser (toner) digital printing machine, color printing speed <80 pages/minute, black and white printing speed <100 pages/minute, mainly used in digital fast printing stores, and it is the main production of short-run printing equipment.

Light-weight production digital printing machines are mainly single-sheet laser (toner) digital printing machines; the color stability is significantly improved, and the convenience of operation and the degree of automation of the equipment are greatly improved.

2. Medium-sized production digital printing machine: the mainstream model of medium-sized production digital printing machine. The monthly production capacity is 300,000 to 1 million pages (A4). Mainly single-sheet laser (toner) digital printing machine, color printing speed is 60~100 pages/min, black and white printing speed is 100~150 pages/min.

The medium-sized production single-sheet laser (toner) digital printer is the main equipment of the regional center store of digital fast printing enterprises, and it is also the entry-level and supporting printing equipment for professional printing enterprises.

3. Heavy-duty production digital printing machine: digital printing equipment with a monthly production capacity of 1 million to 10 million pages (A4). This type of equipment is rich in types, including single sheet (laser or inkjet) digital printers, and roll (laser or inkjet) digital printers. B2 format single-sheet digital printing machines fall into this category. The color printing speed is 60~400 pages/minute, and the black and white printing speed is 100~400 pages/minute. The models of heavy-duty production digital printing machines are relatively diverse. The penetration and integration of digital printing into the traditional printing field is also leading the technological development direction of heavy-duty production digital printing machines. Among them, the heavy-duty production single-sheet laser (toner) digital printing machine is the main equipment for digital printing in professional printing enterprises.

4. Industrial-grade digital printing machine: monthly production capacity exceeds 10 million pages (A4). This type of equipment is dominated by web high-speed inkjet digital printers, with a printing speed of >65 m/min (folded into A4, printing speed exceeds 400 pages/min). Printing paper width>450mm.

This type of equipment pushes the break-even point or critical printing batch of digital printing and offset printing to a higher level. At this batch level, web inkjet digital printers not only have the cost advantages and production capacity of offset printing but also maintain the inherent flexibility of digital printing on-demand production and the convenience of automated production processes. In view of the difference between its printing quality and offset printing, the domestic application of web high-speed inkjet digital printers is mainly concentrated in the field of book printing. In the future, with the improvement of printing quality and the reduction of printing costs, its application will likely be extended to newspapers, magazines, supermarket posters, and commercial promotional materials.

Industrial-grade digital post-press equipment is post-press equipment suitable for large-scale customized production between manual operation equipment for single-piece small-batch production and large-scale industrial production equipment. Its biggest feature is automation to meet the production requirements of multiple varieties, small batches, short cycle times, and high quality.
