Problems solved by technology

[0004] Although the above technical solution can improve the printing effect to a certain extent, the ink is easy to adhere to the printing roller, which needs to be cleaned, dried or removed with a scraper, which seriously affects the printing efficiency

Embodiment 1

[0036] refer to figure 1 , a high-efficiency curing transfer digital roller printing process, comprising the following steps:

[0037] a. Spray the antistatic release ink on the printing roller 1 according to the set position and perform pre-light curing treatment. The pre-light curing treatment adopts ultraviolet light with an intensity of 90W / cm and a wavelength of 313nm for 0.1-0.3s.

[0038] b. Before embossing, the substrate runs close to the pinch roller 2 for a certain distance, and the substrate is preheated by heating the pinch roller 2 . The preheating temperature of the preheating treatment is 90-120°C, so that the antistatic release ink has a certain viscosity on the bonding surface of the substrate, and is transferred to the preheated substrate under the action of pressure.

[0039] c. The substrate preheated in step b is sent between the printing roller 1 and the pressure roller 2, and the antistatic release ink after the pre-light curing treatment in step a is...

Embodiment 2

[0046] This embodiment is basically the same as Example 1, except that the antistatic release ink consists of 10 parts of pigment red, 30 parts of polyurethane, 8 parts of rosin modified phenolic resin, 3 parts of trimethylolpropane trimethylolpropane in parts by weight. Palm kernel ester, 2 parts of paraffin micropowder, 2 parts of polytetrafluoroethylene micropowder, 1 part of salmon cartilage powder, 1 part of photoinitiator, 2 parts of antistatic agent, 0.3 part of defoamer and 40.7 parts of solvent are mixed and ground to 30nm .

[0047] Among them, the photoinitiator is compounded with photoinitiator 907, photoinitiator DETX and photoinitiator ITX in a weight ratio of 3:2:2.

Embodiment 3

[0049]This embodiment is basically the same as Example 1, except that the antistatic release ink consists of 9 parts of pigment yellow, 32 parts of polyurethane, 4 parts of rosin modified phenolic resin, and 5 parts of trimethylolpropane trimethylolpropane in parts by weight. Palm kernel ester, 2 parts of paraffin micropowder, 2 parts of polytetrafluoroethylene micropowder, 1 part of salmon cartilage powder, 2 parts of photoinitiator, 1 part of antistatic agent, 0.4 part of defoamer and 41.6 parts of solvent are mixed and ground to 40nm .

[0050] Among them, the photoinitiator is compounded with photoinitiator 819, photoinitiator DETX, and photoinitiator ITX in a weight ratio of 3:2:1.

Abstract

The invention belongs to the technical field of digital printing, and relates to an efficient curing transfer printing digital roller printing process. The process comprises the following steps of spraying antistatic release ink on a printing roller according to a set position, and carrying out pre-light curing treatment; carrying out preheating treatment on a base material; feeding the preheated base material between the printing roller and a pressing roller, and transferring the antistatic release ink subjected to pre-light curing to the base material through imprinting. The invention further provides efficient curing transfer printing digital roller printing equipment aiming at the process. The equipment comprises the printing roller and the pressing roller, a pressing gap is formed between the printing roller and the pressing roller, a printing ink spray head is arranged above the printing roller, an ultraviolet irradiation device is arranged on a path of one side, turning to the pressing roller, of the printing roller, and a heating device is arranged in the pressing roller. The printing ink is pre-cured in the rapid transfer printing process, so that the printing cleaning accuracy is ensured, and the blooming is reduced.

Description

technical field [0001] The invention belongs to the technical field of digital printing, and relates to a roller printing technology, in particular to a high-efficiency solidification transfer digital roller printing process and equipment. Background technique [0002] Digital printing is the digitization of printing technology. Generally refers to the digitization of part or all of the whole process. Traditional digital printing methods are generally divided into two types, one of which is to use two rollers to sandwich the material in the middle, and the lower roller is immersed in the ink to bring the ink upward to the material; the other is to use the nozzle to print directly In terms of materials, both methods have limitations, which make the printing speed slow, and the ink is easy to scatter, resulting in poor results. At present, some manufacturers use a combination of roller printing and inkjet printing. [0003] For example, the Chinese invention patent with the...
