Embodiment 1
[0033] A method for printing a rough wrinkle effect on a rolling concave online, the steps of which include:
[0034] 1. First make a gravure roll. Taking into account the requirement to achieve sufficient ink transfer, the depth of the cell is required to be high, and the plate-making process chooses the laser plate-making process. For the first plate making, the depth of the cell is determined to be 60u as the determined amount, and the three groups of lines, cell openings and mesh walls are tested as 1#: 70L / inch, 327u, 35u; 2#: 60L / inch, 381u, 42u; 3 #: Parameter setting of 50L / inch, 460u, 48u.
[0035] 2. Second, the preparation of special coarse wrinkle ink. In parts by weight, 20 parts of epoxy acrylic resin, 12 parts of difunctional polyurethane resin, 8 parts of trifunctional monomer, 40 parts of difunctional monomer, 3 parts of initiator, 15 parts of active amine, 1 part of leveling agent, 1 part of Parts of defoamer are mixed to make special coarse crepe ink. Us...

[0040] A method for printing a rough wrinkle effect on a rolling concave online, the steps of which include:
[0041] 1. First make a gravure roll. Taking into account the requirement to achieve sufficient ink transfer, the depth of the cell is required to be high, and the plate-making process chooses the laser plate-making process. In this plate making, the depth of the cell is increased to 100u, and the three groups of lines, cell opening and mesh wall are tested as 1#: 60L / inch, 378u, 45u; 2#: 60L / inch, 468u, 40u; 3#: 40L / inch, 585u, 50u parameter setting.
[0042] 2. Second, the preparation of special coarse wrinkle ink. In parts by weight, 20 parts of epoxy acrylic resin, 10 parts of difunctional polyurethane resin, 10 parts of trifunctional monomer, 40 parts of difunctional monomer, 3 parts of initiator, 15 parts of active amine, 2.5 parts of leveling agent, 0.5 parts of Parts of defoamer are mixed to make special coarse crepe ink. Use the original ink directly on th...
Embodiment 3
[0047] A method for printing a rough wrinkle effect on a rolling concave online, the steps of which include:
[0048] 1. First make a gravure roll. Taking into account the requirement to achieve sufficient ink transfer, the depth of the cell is required to be high, and the plate-making process chooses the laser plate-making process. In this plate making, the number of mesh lines is determined to be 30L / inch, and the three groups of mesh depths, mesh openings and mesh walls are tested as 1#: 150u, 825u, 46u; 2#: 140u, 833u, 38u; 3#: 130u, 846u, 25u parameter settings.
[0049] 2. Second, the preparation of special coarse wrinkle ink. In parts by weight, 10 parts of epoxy acrylic resin, 5 parts of difunctional polyurethane resin, 15 parts of trifunctional monomer, 50 parts of difunctional monomer, 5 parts of initiator, 22 parts of active amine, 1 part of leveling agent, 2 parts of Parts of defoamer are mixed to make special coarse crepe ink. Use the original ink directly on ...
