Embodiment Construction
[0011] The iron printing process with silver cardboard printing effect of the present invention, it comprises the following steps:
[0012] The first step is to make a special silver plate according to the pre-designed pattern that wants to achieve the printing effect of silver cardboard
[0013] Prerequisites for pattern selection: After the four-color color separation plate-making of the selected pattern, one color plate must be a solid plate, or a spot color can be selected for silver cardboard printing effect, and the spot color can have a transition color; when making a special silver plate , the outline of the positive image is slightly smaller than the outline of the selected pattern, generally less than 0.076mm;
[0014] In the second step, use the silver ink with a fineness of less than 5 μm and high brightness and the prepared special silver plate to print the silver ink layer on the tinplate base plate coated with primer or / and coated with white paint. The ink laye...

The invention discloses a metal decorating process with the silver coated paper printing effect. The process comprises the following steps: 1. producing a special silver version based on the designed pattern, wherein the pattern after four-color separation platemaking must contain a color version which is a solid version, or a special color is selected to achieve the silver coated paper printing effect, the special color can have the transition color, and the positive profile is slightly smaller than the selected pattern profile when the special silver version is produced; 2. using silver ink and produced special silver version to print on a tinplate bottom plate coated with bottom oil or / and white paint, and drying; and 3. normally printing other colors on the dried silver ink layer, wherein the four-color pattern or special-color pattern on the outer layer and the special silver pattern at the bottom are accurately printed and the silver pattern cannot be exposed, and finishing the whole printing operation. The process is simple, the printing effect is good, the printed pattern is strong in metal texture, the color is full and attractive, and the effect is close to the printing effect of the silver coated paper.
Description
technical field [0001] The invention relates to a printing process, in particular to an iron printing process which is directly printed on tinplate and has the printing effect of silver cardboard. Background technique [0002] When printing patterns on tin cans, tin boxes and other packaging products, there is a transparent iron printing process, that is, part of the designed pattern is printed directly on the tinplate bottom plate, revealing the metal color of the tinplate, so that the pattern color has a metallic texture, and the other part The pattern is printed on a base plate coated with white paint, similar to normal printing on white paper. This printing process has the following defects: First, the tin plated lines on the tinplate bottom plate can be seen through the iron part, which makes the pattern not delicate enough and affects the appearance; The pattern made on the white paint is dull in color, which affects the grade of the overall packaging product.
