Problems solved by technology

The existing mechanical rainbow printing process is realized by using a printing machine with rainbow printing effect. Due to the limitation of the mechanical structure of the printing machine, only horizontal or vertical rainbow stripe effects can be formed on the printed matter, and the form is single

Embodiment 1

[0030] Rainbow printing process, including the following steps:

[0031] 1) Deploy anti-counterfeiting ink;

[0032] 2) Design printing shading A;

[0033] 3) Divide the shading A into shading B, shading C and shading D, and output printing plate B, printing C and printing plate D, wherein the shading B and / or the shading The pattern C and / or the shading D is a rainbow printing shading;

[0034] 4) Installing the printing plate B, the printing plate C and the printing plate D on different preset printing units respectively;

[0035] 5) After debugging the printing unit, overprint the shading B, the shading C, and the shading D through the printing plate B, the printing plate C, and the printing plate D;

[0036] 6) Protect ink printing. Carry out protective ink printing on the substrate after step 5) rainbow printing, so that the outer surface of the pattern ink layer is covered with a protective ink layer.

[0037] Wherein, in terms of mass fraction, the formula of anti-...

Abstract

The invention relates to an iridescence printing technology. The iridescence printing technology comprises the following steps that (1) anti-forgery ink is prepared; (2) a printing shading A is designed; (3) the printing shading A is divided into a shading B, a shading C and a shading D, and the shading B, the shading C and the shading D are output to be manufactured into a printing plate B, a printing plate C and a printing plate D, wherein the shading B and / or the shading C and / or the shading D are / is iridescence printing shadings; (4) the printing plate B, the printing plate C and the printing plate D are installed on different printing units which are set in advance correspondingly; (5) after the printing units are debugged, the shading B, the shading C and the shading D are overprinted together; and (6) protective ink printing is carried out. According to the iridescence printing technology, the limitation of forms of single stripes generated by a traditional mechanical iridescence printing technology is combined with an iridescent pattern design printing technology, so that more abundant iridescence printing effects are generated, and the higher-end anti-fake function is achieved; and since a vacuum coating film is arranged, the ink print is prevented from falling off.

Description

technical field [0001] The invention relates to the field of printing, in particular to a rainbow printing process. Background technique [0002] "Rainbow" or "rainbow effect" refers to the effect of printing when different colors of ink are used on the same printing unit. The rainbow printing process can realize the gradual transition from one color to another on the printed matter. This effect is the component and premise of anti-counterfeiting printing. In other words, this is a very important anti-counterfeiting element that can make those who try to counterfeit products feel at a loss. [0003] At present, if domestic printing companies want to achieve the effect of rainbow printing, they must modify the printing machine, divide the ink tank into several parts, and then put different inks respectively. The edges of the ink have been kneaded together, and the printed pattern is like a rainbow. The existing mechanical rainbow printing process is realized by using a pri...
