Transfer paperboard gravure printing process

The invention discloses a transfer paperboard gravure printing process. The transfer paperboard gravure printing process comprises the following steps: firstly, printing varnish on a unit type gravureprinting machine by taking a reel transfer paperboard as a printing object; secondly, printing images and texts with other color sequences, and arranging the printing color sequences according to specific product requirements; and thirdly, carrying out connecting line concave-convex processing, cutting through a transverse cutting machine to obtain a single sheet of paper printed matter, and transferring to the next process. In the process, varnish printing is added on the transfer paperboard, varnish printing is carried out before color ink of the images and the texts is printed, the varnishis colorless, the function of the varnish is to lay the bottom before the images and the texts are formally printed, the tension of the reel transfer paperboard can be stabilized through varnish printing, the problem that the
