Problems solved by technology

[0004] Particle protrusions often occur on the surface of substrates (such as paper) printed by volatile drying inks in the prior art. The main reason is that the substrates do not fully absorb ink, and the particle protrusions will seriously affect the printing quality. Therefore There is an urgent need for a printing method that can solve this problem

Embodiment 1

[0026] The volatilization and drying type printing method comprises the following steps:

[0027] Step 1, printing preparation: prepare a frame 1, install a solvent spray box 4 in the frame 1, and pass solvent vapor isopropanol into the solvent spray box 4, and install some transfer rollers 5 below the solvent spray box 4 A translation mechanism that utilizes the rotation of the transmission roller 5 to carry out reciprocating translation is installed on one side of the transmission roller 5, and an inking mechanism that utilizes the rotation of the transmission roller 5 to perform intermittent ink coating is installed on the other side of the transmission roller 5. The inking mechanism includes The embossing cylinder 2 and the ink cartridge 3 are installed on the top of the conveying roller 5 and use a translation mechanism to intermittently open and close the covering mechanism of the solvent spray box 4 .

[0028] Specific as figure 1 As shown: the embossing cylinder 2 is ...

Embodiment 2

[0038] The difference between this embodiment and embodiment 1 is:

[0039] Ink in step 3 comprises 20kg linking material by mass, 10kg pigment, 80kg organic solvent, 5kg manganese dry oil and 8kg menthol; Linkage comprises 15kg epoxy resin and 5kg polyester resin by mass;

[0040] In step 4, the drying temperature is 55°C;

[0041] The air-drying wind speed in the step 5 is 2.5m / s.

Abstract

The invention belongs to the technical field of printing, and particularly relates to a volatilization drying type printing method. The printing method comprises the following steps that 1, printing preparation is carried out, wherein a solvent spraying box is prepared, solvent vapors is introduced into the solvent spraying box, multiple conveying rollers are installed below the solvent spraying box, a translation mechanism is installed on one sides of the conveying rollers, the other sides of the conveying rollers are provided with an ink coating mechanism, and a covering mechanism is installed above the conveying rollers; 2, wetting is carried out, wherein a printing stock is conveyed to the lower part of the solvent spraying box through the conveying rollers, meanwhile, the translationmechanism and the covering mechanism are used for automatically opening the solvent spraying box through rotation of the conveying rollers, and the solvent vapors sinks to the surface of the printingblock for wetting; 3, ink is applied, wherein the printing block is reversely conveyed to the ink coating mechanism through the conveying rollers, and the ink coating mechanism is used for automatically coating the printing block with the ink by means of rotation of the conveying rollers; 4, drying is carried out; and 5, cooling is carried out. According to the scheme, particle protrusions can beeffectively prevented from being generated on the surface of the printing block, and the printing quality is improved.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a volatilization and drying printing method. Background technique [0002] Gravure printing products have the advantages of thick ink layer, rich layers, strong three-dimensional effect, and good printing quality. They are mainly used for printing exquisite color pictures, trademarks, decorations, securities, and color newspapers. When printing on a gravure printing machine, the entire surface of the plate cylinder is inked, and the ink on the blank part of the plate is scraped off with a squeegee, leaving the ink on the graphic part, and then passed through the paper, and the impression cylinder is embossed on the back of the paper. The ink in the concave part is directly transferred to the paper surface, and finally the printed matter is piled up or rewound through the receiving part. [0003] Among them, the ink is mostly composed of 20% to 40% binder, 5% to 15% ...
