Abstract

The invention discloses an ink-jet plastic printing process, belonging to a printing process. The ink-jet plastic printing process comprises flat plate printing and plastic printing; printing ink on the silica gel sheet by using a flat-bed printer through designing an initial pattern to be printed by a computer, and forming a middle pattern on the silica gel sheet; and plastic printing, namely placing the printed matter on a workbench with a vacuum adsorption device, covering the silica gel sheet above the printed matter, enabling the pattern surface of the silica gel sheet to face the printed matter, carrying out vacuum adsorption on the silica gel sheet through the vacuum adsorption device of the workbench, and after the silica gel sheet is vacuumized and molded, enabling the silica gel sheet to be attached to the printed matter tightly so as to print the ink on the printed matter, wherein the final pattern is formed on the printed matter, and the plastic printing process needs to be completed within the plastic printing time. The invention is used as the ink-jet plastic printing process, has simple manufacturing process, beautiful pattern color and vivid effect, and can be used for printing on printed matters with any shapes.

Description

Inkjet plastic printing process

technical field

The invention relates to a printing process, in particular to an ink-jet plastic printing process.

Background technique

Flatbed printer is a kind of "non-contact" inkjet printing high-tech digital printing equipment, which can print color patterns on the surface of any material, fast printing and proofing, and can be printed at one time. Universal printer can print any material and Irregular soft and hard objects, such as metal, ceramics, crystal, glass, acrylic, PVC, plastic, toys, leather, U disk, cloth, wood, silicone, rice paper, etc. Whether it is a simple block-color pattern, a full-color pattern or a pattern with excessive color, it can be printed at one time without plate making, printing and repeated color registration. The color is beautiful, the effect is realistic, the image is waterproof, sunscreen, and wear-resistant Strong force, no fading, easy operation of the machine, stable performance, creating higher printing quality than traditional methods, but the flatbed printing technology is not affected by the huge cost of the production quantity, and is very satisfied with the changes and small quantities. Nowadays, the market is dominated by personalized products, but the flatbed printing technology is very limited by the appearance of the product, and the distance between the product and the nozzle is limited to no more than 5.0mm, which limits the use of flatbed printers.

Contents of the invention

In order to solve the above problems, the present invention provides an inkjet plastic printing process, which has a simple production process, beautiful patterns and colors, and realistic effects, and can be printed on printed matter of any shape.

The technical solution adopted by the present invention is: inkjet plastic printing process, including flat printing and plastic printing;

Flatbed printing, the initial pattern to be printed is designed by the computer, and the ink is printed on the silica gel sheet by a flatbed printer, and an intermediate pattern is formed on the silica gel sheet;

Plastic printing, place the printed matter on a workbench with a vacuum adsorption device, cover the silicone sheet on the printed matter with the pattern side of the silicone sheet facing the printed matter, and vacuum absorb the silica gel sheet through the vacuum adsorption device of the workbench. When the silicone sheet After being vacuum-pumped, the silicone sheet sticks to the printed matter so that the ink is printed on the printed matter, and the final pattern is formed on the printed matter. The plastic printing process must be completed within the plastic printing time.

In the above technical solution, the main components of inkjet are 20% resin, 17% pigment, 60% solvent and 3% additive.

In the above technical solution, the initial pattern is a mirror image reverse pattern of the final pattern.

In the above technical solution, the thickness of the silica gel sheet is not more than 1.5mm. the

In the above technical scheme, the printing time is 3-10 seconds.

The beneficial effect of the present invention is that: the above-mentioned inkjet plastic printing process does not directly print the image on the surface of the final product, but uses a silica gel sheet as a mediator to finally transfer the image from the silica gel sheet with the help of vacuum suction Printed on the product; use a flatbed printer to print, no need for plate making, no need for printing and repeated color registration, beautiful colors, realistic effects, easy operation of the machine, stable performance, and higher printing quality than traditional methods; It can be attached to the printed matter, and it can completely print the initial pattern on the surface of any shape of the printed matter, breaking the limitation of flatbed printing technology by the appearance of the product, and will not limit the distance between the printed matter and the nozzle of the flatbed printer to no more than 5.0mm , will not limit the use of flatbed printers.

Description of drawings

Figure 1 is a flow chart of the present invention.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

Fig. 1 schematically shows an inkjet plastic printing process according to an embodiment of the present invention.

The inkjet plastic printing process includes flat printing and plastic printing;

Flatbed printing, the initial pattern to be printed is designed by the computer and the initial pattern is the mirror image of the final pattern, and the flatbed printer is used to print the ink on the silica gel sheet to form an intermediate pattern on the silica gel sheet. The main components of the inkjet are: 20% resin, 17% pigment, 60% solvent and 3% additive, the thickness of the silica gel sheet does not exceed 1.5mm.

Plastic printing, place the printed matter on a workbench with a vacuum adsorption device, cover the silicone sheet on the printed matter with the pattern side of the silicone sheet facing the printed matter, and vacuum absorb the silica gel sheet through the vacuum adsorption device of the workbench. When the silicone sheet After being vacuum-pumped, the silicone sheet sticks to the printed matter so that the ink is printed on the printed matter, and the final pattern is formed on the printed matter. The plastic printing process must be completed within 5 seconds of the plastic printing time.

The above embodiments are only intended to illustrate rather than limit the present invention, so all equivalent changes or modifications made according to the methods described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
