Problems solved by technology

Due to the necessity of inter-color drying, the following problems are brought about: one is that only stacked printing units or horizontal linkage printing units can be used, and satellite printing units and satellite printing processes with many advantages cannot be used; the other is high temperature The heat source may burn the substrate while drying the ink quickly; the third is that the overall printing speed is limited, because if the printing speed is too fast, it means that the substrate runs fast, which may cause the drying time between colors to be too short ; The fourth is the need for multiple sets of high-efficiency drying equipment (for example, a total of eight sets of drying equipment are required for double-sided four-color printing), which increases the cost of equipment manufacturing

Abstract

The invention relates to a dual-surface printer, which comprises two planet printers, wherein the central compress rollers of printers are parallel mounted; there are two transverse bake channels above the printers; two bake layers are layered inside the bake stove. The invention can print without drying inter-color; and the paths of two times of drying can be reversed and layered, to shorten the base material path. And the invention also provides a relative printing method.

Description

technical field [0001] The invention relates to a printing machine and a printing process, in particular to a double-sided printing device and a double-sided printing process. Background technique [0002] In the process of double-sided printing on the substrate, before printing the reverse side, it must be ensured that the ink on the front side is dry (in this application document, the so-called front side of the substrate refers to the side of the substrate that accepts printing earlier; the other side is Therefore, the "front" and "reverse" in this application document are not necessarily equal to the "front" and "reverse" in daily life). In the existing equipment and technology for double-sided, continuous and uninterrupted multi-color printing on rolls of substrates, due to the limitations of equipment conditions, the size of the equipment, and the direction of the substrate, it can only be done every time. After printing one color on one side, the ink is immediately d...
