Ultraviolet curing offset printing process capable of printing plane bas-relief effect

Abstract

The invention discloses an ultraviolet curing offset printing process capable of printing a plane bas-relief effect. The process comprises the following process steps of A, designing a bas-relief pattern and manufacturing a draft, specifically, designing the bas-relief pattern through design software of a computer and manufacturing the draft with the bas-relief pattern, wherein the bas-relief pattern comprises a relief part and a contour line part which is more convex than the relief part; B, selecting a proper offset press and performing color sequence design; C, manufacturing a printing plate, specifically, inputting the draft into a plate making machine, and manufacturing the printing plate through a CTP plate; D, selecting a printing material, specifically, selecting the printing material with a proper dyne value according to requirements; And E, starting up for printing, specifically, putting the printing material in the step D into a paper feeding mechanism of the offset press, then starting up for printing, and thus the printing material becomes a printed finished product after undergoing the printing process and collected by a paper collecting mechanism.

Description

technical field [0001] The invention relates to the technical field of ultraviolet curing offset printing technology, in particular to an ultraviolet curing offset printing technology capable of printing flat bas-relief effects. Background technique [0002] At present, there are two main techniques for printing embossed effects in the packaging and printing industry: one is stamping on paper or film, and in the process of making embossed stamping plates, the embossed effect is displayed through concave and convex arcs. The disadvantage of the above process is the printing cost. High cost, low printing efficiency, and difficult to quickly mass-print; the second is to use high-precision automatic screen printing equipment to overprint multi-layer varnish on cardboard or film. The disadvantage of the above process is that the printing speed is slow and the printing efficiency is low. , equipment requirements are high, and printing costs are extremely high. The existing conven...

[0002] At present, there are two main techniques for printing embossed effects in the packaging and printing industry: one is stamping on paper or film, and in the process of making embossed stamping plates, the embossed effect is displayed through concave and convex arcs. The disadvantage of the above process is the printing cost. High cost, low printing efficiency, and difficult to quickly mass-print; the second is to use high-precision automatic screen printing equipment to overprint multi-layer varnish on cardboard or film. The disadvantage of the above process is that the printing speed is slow and the printing efficiency is low. , high equipment requirements, high printing costs

The existing conventional UV curing offset printing process cannot print the effect of bas-relief mainly because the printing thickness of the ink is difficult to achieve the concave-convex effect of bas-relief
