Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, and more specifically to a digital printing fast drying device. Background Art

[0002] Digital quick printing, also known as short-run printing or digital printing, is different from traditional printing in that it can print from one sheet, the data can be changed, and the images and texts can be transmitted in various media, which greatly expands the commercial application scope of digital imaging. Digital quick printing is a new printing technology that uses the pre-press system to directly transmit the image and text information through the network to the digital printing machine to print color prints.

[0003] After the current digital printing equipment prints on the material, the temperature of the surface of the printed material is high and the ink is not completely cured, which can easily cause the ink attached to the material to stick to another material. The current drying structure mostly dries the side of the material printed with ink. Single-sided drying can easily cause paper curling, affecting the effect of digital printing. In view of this, we propose a digital printing fast drying device. Utility Model Content
