Embodiment 1

[0015] Embodiment one: The composition of UV primer is as follows according to mass percentage: chlorinated polyester 50%, epoxy acrylic resin 10%, polyester 24.8%, photosensitizer 3%, polymerization inhibitor 0.2%, silica sand powder 2% %, wax powder 2%, superfine talc powder 4%, silicone additives 4%; the composition of UV top oil is as follows in terms of mass percentage: epoxy acrylic resin 30%, polyurethane acrylic resin 14%, acrylic monomer 43% , Photosensitizer 10%, Inhibitor 0.1%, Silicone Auxiliary 1.5%, Shrinkage Auxiliary 1.4%. The ratio of base oil to top oil is 1:1.1.

[0016] Step 1: Print the first matte UV primer on the paper using the offset printing PS plate printing color set.

[0017] Step 2: Print the second UV topcoat in flexographic mode on the glazing seat of the offset printing machine. The glazing seat needs to make a flexible resin plate of the corresponding file. The glazing seat uses a cavity-type scraper to match the anilox roller for inking. Us...

Embodiment 2

[0019] Embodiment two: the composition of UV primer is as follows according to mass percentage: 44% of chlorinated polyester, 11% of epoxy acrylic resin, 23% of polyester, 3% of photosensitizer, 0.2% of polymerization inhibitor, silica sand powder 5% %, 4.8% wax powder, 4% superfine talc, 5% organic silicon additives; the composition of UV top oil is as follows in terms of mass percentage: epoxy acrylic resin 25%, polyurethane acrylic resin 12%, acrylic monomer 50% , photosensitizer 10%, polymerization inhibitor 0.1%, silicone additive 1.9%, shrinkage additive 1%. . The ratio of base oil to top oil is 1:1.3.

[0020] Step 1: Print the first matte UV primer on the paper using the offset printing PS plate printing color set.

[0021] Step 2: Print the second UV topcoat in flexographic mode on the glazing seat of the offset printing machine. The glazing seat needs to make a flexible resin plate of the corresponding file. The glazing seat uses a cavity-type scraper to match the...

Embodiment 3

[0023] Embodiment three: the composition of UV primer is as follows according to mass percentage: 40% chlorinated polyester, 10% epoxy acrylic resin, 22% polyester, 3% photosensitizer, 0.2% polymerization inhibitor, silica sand powder 8 %, wax powder 6%, superfine talc powder 6%, silicone additive 4.8%; the composition of UV top oil is as follows in terms of mass percentage: epoxy acrylic resin 24%, polyurethane acrylic resin 10%, acrylic monomer 50% , photosensitizer 12%, polymerization inhibitor 0.1%, silicone additive 2%, shrinkage additive 1.9%. The ratio of base oil to top oil is 1:1.5.

[0024] Step 1: Print the first matte UV primer on the paper using the offset printing PS plate printing color set.

[0025] Step 2: Print the second UV topcoat in flexographic mode on the glazing seat of the offset printing machine. The glazing seat needs to make a flexible resin plate of the corresponding file. The glazing seat uses a cavity-type scraper to match the anilox roller for...

Abstract

The invention discloses a printing method for realizing the matte effect by using an offset printing machine. The offset printing PS printing color group is used to first print the first matte UV base oil, and then print the second UV surface in a flexographic manner on the glossing seat of the offset printing machine. Oil, and finally UV cured to form a matte ink effect; the ratio of base oil to top oil is 1:1.1~1:1.5. In the current situation that there are many combined processes for packaging products, the present invention is a production method that improves production efficiency and is easy to control the batch effect.

Description

technical field [0001] The invention relates to a frosting effect printing method. Background technique [0002] The matte effect of existing printed products is usually achieved by silk screen printing or single concave, but usually the efficiency of silk screen printing is low and the labor cost is high, while single concave is expensive in plate making and difficult to restore the effect. [0003] Chinese patent (CN 1709707 A) discloses an offset printing frosting process, which includes three steps: 1, printing the first layer of primer and curing it with ultraviolet radiation; 2, printing the second layer of primer and curing it with ultraviolet radiation; 3, the printing surface Oil and irradiate with ultraviolet light to make the 5 surface oil and base oil react to form a simulated scrub effect. However, this method needs to be printed three times, and each time printing needs to be cured by ultraviolet radiation. Not only are there more processes, but the grainines...
