Embodiment Construction
[0044] The present invention will be further described below in combination with specific embodiments. Terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in the preferred embodiment are only for convenience of description, and are not used to limit the scope of the present invention. The scope of implementation and the change or adjustment of its relative relationship shall also be regarded as the scope of implementation of the present invention without substantive changes in technical content.
[0045] The inventor of the present application has learned through creative work and multiple experiments that the transfer performance and adhesion performance of ink are mainly related to the tension of the paper surface. Therefore, according to this finding, the inventors carry out surface treatment to the printing material before the digital printing coating (primer), so that any kind of printing material all has the surface tension that meets the requireme...

Abstract
The invention discloses a paper printing method. The paper printing method comprises the following steps that (1), water-based polishing oil is coated on paper to be printed, so that the surface tension of the paper coated with the water-based polishing oil is greater than or equal to a preset value; (2), special coating liquid for digital printing is coated on the paper coated with the water-based polishing oil; and (3), digital printing is carried out on the paper coated with the special coating liquid for the digital printing. According to the paper printing method, not only can the ink transfer performance and the adhesion performance of the digital printing be better, but also the performance is stable and the quality is reliable; and ready availability is realized after a test is qualified, the digital printing is particularly flexible and convenient for a color box packaging printing enterprise which frequently replaces printing materials, and the production efficiency is greatly improved. In addition, due to the stable surface properties of the printing materials, the amount of the digital printing coating liquid can be reduced, the cost is saved, and the technical requirements for the digital printing coating (first coating) process are reduced, so that stable quality can be achieved by an ordinary rubber roller coating machine.
Description
technical field [0001] The invention relates to the technical field of printing, in particular to a paper printing method. Background technique [0002] In the field of digital printing, due to its high production efficiency and good printing quality, it has begun to be used more and more in the packaging and printing industry, especially in high-end color box packaging and printing companies. The use of digital printing machines for printing and proofing not only greatly improves production It is a kind of green printing behavior in line with the current energy saving and environmental protection. [0003] Good ink transfer performance and adhesion performance are one of the most important indicators to measure printing quality. However, the digital printing of the prior art has poor ink transfer performance and poor adhesion performance, especially on printing materials such as aluminum foil cardboard, medium cardboard, and film composite paper commonly used in color box ...
