Problems solved by technology

At present, UV reverse frosting is made on ordinary offset ink prints. After the ordinary offset ink prints are completely dry, it is necessary to print a layer of UV water-based primer (otherwise the adhesion is too poor), and then the UV reverse can be printed after it is completely dry. Primer and surface oil, while printing UV water-based primer needs to be dried with hot air or heated by infrared lamps to dry out the UV water-based primer, resulting in low printing efficiency and troublesome operation, which has caused great troubles for printing manufacturers

Embodiment 1

[0034] The preparation method of the UV offset printing ink of embodiment 1, comprises the following steps:

[0035] (1) Mix the polymerizable prepolymer A with the photosensitive monomer, and disperse it with a mixer at a speed of 1400r / min. After the polymerizable prepolymer A is completely dissolved and the fineness reaches below 5 μm, add photoinitiator A, After the filler and additive A, disperse and stir evenly at a speed of 600r / min, use a grinder to grind until the fineness reaches below 15 μm, and obtain the reverse base oil;

[0036] (2) Mix the polymeric prepolymer B with the reactive diluent, and disperse it with a mixer at a speed of 1400r / min. After the polymeric prepolymer B is completely dissolved and the fineness reaches below 5 μm, add photoinitiator B and Additive B is then dispersed at a speed of 1300r / min until the fineness reaches below 5 μm to obtain the reverse surface oil.

Abstract

The invention discloses a making method of a UV (ultraviolet) reverse dull polish process. A UV offset ink disclosed by the invention comprises reverse bottom oil and reverse surface oil, wherein thereverse bottom oil comprises the following components in parts by weight: 25-35 parts of a polymerism prepolymer A, 40-60 parts of a light sensitive monomer, 5-15 parts of a light initiator A, 5-15 parts of a filling material and 5-10 parts of an additive A; and the reverse surface oil comprises the following components in parts by weight: 15-25 parts of a polymerism prepolymer B, 55-70 parts of an active diluent, 5-15 parts of a light initiator B and 1-10 parts of an additive B. By preferring components and proportions of the reverse bottom oil and the reverse surface oil, the components arematched with one another, original viscosity, fineness, 4-cup coating viscosity and drying properties of the prepared reverse bottom oil and reverse surface oil can be maintained, in addition, the contact adhesiveness of the oil with a common offset ink product is greatly improved, and a UV reverse dull polish effect can be directly achieved on the common offset ink product.

Description

technical field [0001] The invention relates to the technical field of printing inks, in particular to a method for making a UV reverse frosting process. Background technique [0002] With the rapid development of offset printing in the field of packaging technology, a variety of paper packaging boxes have emerged in due course, among which UV reverse matte production technology has become an inevitable trend in the development of packaging and printing. Various ink manufacturers around the world have launched their own UV offset printing inks and UV reverse frosting process production methods, and the process of making UV reverse frosting on ordinary offset ink prints has also emerged in due course. At present, UV reverse frosting is made on ordinary offset ink prints. After the ordinary offset ink prints are completely dry, it is necessary to print a layer of UV water-based primer (otherwise the adhesion is too poor), and then the UV reverse can be printed after it is comp...
