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] reference Figure 1 , an efficient curing transfer digital roller printing process that includes the following steps:

[0037] a. The antistatic ionization ink is sprayed on the printing roller 1 according to the set position and pre-optical solid treatment is carried out. The pre-optical solid treatment uses ultraviolet light with an intensity of 90W / cm and a wavelength of 313 nm to irradiate 0.1 to 0.3 s.

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

[0039] c. The preheated substrate in step b is fed between the printing roller 1 and the pressed roller 2 and the antistatic ionization ink after pre-light fixing in ste...

Embodiment 2

[0046] The present embodiment is substantially the same as Example 1, the difference is that the antistatic ionization ink by weight by 10 parts of pigment red, 30 parts of polyurethane, 8 parts of rosin modified phenolic resin, 3 parts of trimethylolpropane tripal palm kernel ester, 2 parts paraffin powder, 2 parts of PTFE micro powder, 1 part of salmon cartilage powder, 1 part of photoinitiator, 2 parts of antistatic agent, 0.3 parts of defoamer and 40.7 parts of solvent mixed grinding to 30nm.

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

Embodiment 3

[0049] The present embodiment is substantially the same as Example 1, the difference is that the antistatic ionization ink by weight by 9 parts of pigment yellow, 32 parts polyurethane, 4 parts rosin modified phenolic resin, 5 parts trimethylolpropane tripalm, 2 part paraffin powder, 2 parts PTFE powder, 1 part salmon cartilage powder, 2 part photoinitiator, 1 part antistatic agent, 0.4 parts defoamer and 41.6 parts solvent mixed grinding to 40nm.

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

Abstract

This application belongs to the technical field of digital printing, and relates to a high-efficiency curing transfer digital roller printing process, which sprays antistatic release ink on the printing roller according to the set position and performs pre-light curing treatment; pre-heating the substrate ; Send the pre-heated substrate into between the printing roller and the pinch roller to transfer the pre-light-cured antistatic release ink to the substrate by embossing. Also provided is a high-efficiency curing transfer digital roller printing device for the above process, including a printing roller and a pinch roller, there is an embossing gap between the printing roller and the pinching roller, an ink nozzle is arranged above the printing roller, and the printing An ultraviolet irradiation device is arranged on the path where the roller turns to the pressing roller, and a heating device is arranged in the pressing roller. The ink is pre-cured during the rapid transfer process to ensure accurate cleaning of the print and reduce smudges.

Description

Technical field [0001] The present invention belongs to the field of digital printing technology, relates to a roller printing technology, in particular to a highly efficient curing transfer digital roller printing process and equipment. Background [0002] Digital printing is the digitization of printing technology. Generally refers to the digitization of the whole process in part or in whole. The traditional digital printing method is generally divided into two kinds, one is the use of two rollers to sandwich the material in the middle, the roller located below is immersed in the ink to bring the ink upwards to the material; the other is to use the nozzle to directly print on the material, both methods have limitations, so that the printing speed is slow, and the ink is easy to disperse and lead to poor results. At present, some manufacturers use a combination of roller printing and inkjet printing methods. [0003] For example, the Chinese invention patent with patent applicat...
