Abstract

The invention provides a continuous digital gravure overprinting method. The continuous digital gravure overprinting method is characterized by comprising the following steps: (1) unreeling and feeding; (2) detecting the unpeeling tensile force; (3) performing gravure printing; (4) drying; (5) conveying by using a conveying mechanism; (6) performing digital printing; (7) reeling to collect the material, wherein digital registration detection (6-1) should be performed in the digital printing step (6), namely a detecting optical probe acquiring unit is arranged for detecting the digital ink jet position of printing paper so as to judge whether the ink jet position is incorrect; if the ink jet position is deviated, a digital hauling part is used for adjusting the printing paper to reach the correct position; the digital ink jet with the combination characteristics is also combined with a one-time-printing one-time-drying scheme of a conventional gravure printer; the continuous digital gravure overprinting method provided by the invention is capable of integrating the advantages such as overprinting property, large reprinting ink amount, widened design range, three-dimensional beauty of digital ink jet and rapid formation of gravure printing.

Description

technical field [0001] The invention patent relates to an innovative combination of gravure printing and digital inkjet printing, which is applied to the printing and printing of roll paper and film. This machine integrates the advantages of traditional gravure printing and modern digital inkjet printing, and also makes up for the shortcomings of gravure printing and digital printing. It has become another revolutionary upgrade and leading development in the field of transfer printing paper in the textile industry. Background technique [0002] Previously, the printed paper in this field was completed by a gravure printing machine. After printing, the flower shape on the printed paper was transferred to the cloth by a hot roller blanket transfer machine, and the printed cloth was produced. Paper acts as a medium. With the development and evolution of technology, digital inkjet printing technology is the general trend, and gravure printing machines are facing a large reducti...
