Inkjet printing method and inkjet printing equipment for realizing method

Abstract

The invention provides an inkjet printing method. The method adopts a rotating roller plated with chromium on the surface as a middle transfer printing body; an inkjet printing head is firstly adoptedto spray UV gloss oil to the surface of the cooled middle transfer printing body; a multi-color inkjet printing head is adopted to spray UV ink on a gloss oil layer; then, the middle transfer printing body with the gloss oil layer and an image layer pass through a first UV curing device, so that the image layer is primarily cured; meanwhile, the surface temperature of the middle transfer printingbody is increased for transfer printing of the image layer and the gloss oil layer from the middle transfer printing body onto a printed substrate; and finally, the printed substrate with images passes through second and third UV curing devices in sequence, so that the image layer and the gloss oil layer are thoroughly cured, wherein the gloss oil layer and the image layer contain light initializing agents sensitive to different wave sections of light. The inkjet printing method can guarantee thorough and clean transfer printing of the images on printed matters at each time, and meanwhile, guarantees high definition of the images. The invention further provides inkjet printing equipment for realizing the method.

Description

technical field [0001] The present invention relates to a printing method, in particular to an inkjet printing method, more particularly to an indirect transfer inkjet printing method. The present invention also provides an inkjet printing device for realizing the above method. Background technique [0002] Inkjet printing is a digital technology that prints different images on a continuous sheet. In recent years, inkjet printing technology has developed rapidly, and has gradually replaced traditional printing methods in advertising, ceramics, textiles, wallpaper and other industries. The common inkjet printing methods on the market are direct printing methods, that is, ink droplets are directly sprayed on the printing material. Due to the simple structure and low cost of direct printing equipment, it is the mainstream printing method in the market at present, but there are many shortcomings in the direct printing method, such as the surface properties of various printing ...
