Description

Technical Field

[0001] The utility model relates to the technical field of digital printing, in particular to a digital printing color fixing machine. Background Art

[0002] Digital printing is a new printing method that prints computer files directly on paper, which is different from the cumbersome process of traditional printing. Its characteristics: printing from one sheet, no need for plate making, immediate availability, instant error correction, variable printing, and printing on demand. Digital printing is a comprehensive technology developed on the basis of printing technology. It uses electronic text as a carrier and transmits it to digital printing equipment through the network to achieve direct printing. The biggest features of the printing production process are the absence of plates and variable information, covering a variety of technical fields such as printing, electronics, computers, networks, and communications.

[0003] After digital printing, a tunnel dryer is usually used to heat and dry the printed products. After drying, the colors are more vivid and less likely to fall off.
