Embodiment 1

[0047] 1. Make a template

[0048] A template with a hollow relief pattern is produced by screen printing, and the mesh number of the template is 77T.

[0049] 2. Printing front core layer

[0050] Place a template with a hollow relief pattern on the upper surface of the front core layer, and then print varnish on the template, so that the varnish is transferred to the upper surface of the front core layer through the hollow template, and then place it in an oven at 60°C to dry After 3 minutes, the varnish is dried and solidified on the front core layer to obtain a front core layer with embossed patterns; among them, the material of the front core layer is laser PVC material with a thickness of 0.3mm, and the varnish composition is acrylic ester.

[0051] Print other necessary graphics on the surface of the front core layer that has already printed the embossed pattern, and combine with varnish to make the entire inner embossed card beautiful and complete.

Abstract

The invention discloses a preparing method for an inner embossment card. The preparing method includes the steps that a template with hollow embossment patterns is manufactured; the upper surface of a front face core layer is printed through the template, and the embossment patterns are formed on the upper surface of front face core layer; the front face core layer with the embossment patterns is placed and fixed between a bottom layer and a surface film on the front face, and a card material is obtained; and the card material is pressed to obtain the card with the inner embossment patterns. In the pressing process, the embossment patterns on the upper surface of the front face core layer sink in the direction of the front face core layer under the pressure effect, and a height difference is formed between the embossment patterns and the surface of the blank front face core layer, so that a reflection path of light is changed, and the inner embossment effect is formed. The method is firstly provided, the card prepared from the method is smooth in surface, the inner embossment patterns with the concave-convex view sense are arranged inside, the quality of the card is good, the durability is high, the anti-falsification is high, and the extremely-high application value is achieved.

Description

technical field [0001] The invention relates to a method for preparing a card, in particular to a method for preparing an inner embossed card, and belongs to the field of card manufacturing. Background technique [0002] At present, there are a variety of card surface technology in the field of card manufacturing. In the traditional technology, to achieve the relief effect, it is necessary to print screen varnish on the surface of the card, and form relief graphics after drying. This embossing effect will make the surface of the card uneven, and the flatness of the entire card surface is not good. In the process of hot stamping the signature strip in the later stage, the uneven card surface will easily cause partial peeling of the signature strip or excessive indentation. The problem is that there are similar problems with the effect of embossed hot characters, which makes the surface of the bank card easily damaged and affects the aesthetics and service life of the card. ...
