Abstract
The invention relates to the technical field of digital printing, in particular to a printing method. The printing method provided by the embodiment of the present invention can form a precoating liquid layer on the surface of the substrate through the precoating roller when the substrate is conveyed to the precoating roller; and, when the substrate is conveyed to the digital printing device and the precoating liquid When the layer is in a wet state, print the target graphic on the pre-coating liquid layer by a digital printing device. Since this method can print target graphics on the pre-coating liquid layer when the pre-coating liquid layer is in a wet state, since the moisture in the pre-coating liquid will be absorbed by the substrate, after the substrate is saturated, the digital jet printing device will spray The ink will no longer penetrate into the inside of the substrate, and the color of the target graphic will be relatively bright; in addition, since the pre-coating liquid in a wet state can also undergo an adhesive reaction with the ink, the target graphic formed on the substrate It has a certain waterproof effect.
Description
technical field [0001] The invention relates to the technical field of digital printing, in particular to a printing method. Background technique [0002] In digital printing, the pattern to be printed is usually input into the computer in digital form, and after image software processing, the computer controls the nozzle of the digital printer to spray ink onto the substrate to form a pattern. In order to improve the quality of digital printing patterns, before the ink is sprayed by the nozzle, it is usually necessary to pre-coat the pre-coating liquid on the roll paper before digital printing. For example, on a production line, the pre-coating liquid can be applied to the web first, and after the pre-coating liquid layer on the web is dried, digital printing can be performed on the pre-coating liquid layer by a digital printer. [0003] In the process of realizing the present invention, the inventor found that in the prior art, because the ink of the digital printer is di...
