Polyester Printing Mesh Process
The popular print T-shirt pattern. Generally, it can be divided into three process sources. Today we introduce a more traditional, technically mature Polyester printing mesh.
Polyester printing mesh. We started the analysis from prepress. Silk polyester printing mesh is to separate the design drawings by color. Through the process of plate making, the separately separated colors are printed separately. So, most of them are a color that needs to be opened with a screen printing . This is more general. Also called the spot color silk screen. Plate making requires filming. Generally, 45 wires are used, and the number of mesh yarns is 100-135 mesh. In addition, there is a CMYK four-color printing, which is to split the whole pattern into four primary colors. Through the principle of stacking, the film has 55 lines to 65 lines. The mesh number is about 300 mesh. For different patterns, different color separation methods are used to achieve screen printing. The higher the fineness, the higher the degree of reduction for the pattern. The finer the color is. The degree of reduction is also higher. This is pre-press preparation. So the more boards you open, the higher the cost. The more colors, the higher the cost. In the process of printing. The printing will make the choice of printing materials according to the different shirt color and different printing pattern colors. Can be divided into several major categories.
The first is the water paste printing. The color you need to print must be the color that can cover the bottom of the T-shirt. This can be achieved. You can take a watercolor to refer to. On the top of the white paper, you can draw any color, but on the black paper, the watercolor pen draws the color. Can't show up. In the same way, drawing a deep color on a light-colored dress can also be achieved, but it involves a process of changing colors and contrasting colors. For example, if you paint blue on a yellow dress, it will turn green. The advantage of water jet printing is that it is soft to the touch and very breathable. The pigment adheres to the cotton fiber by a solid slurry (resin component), and the texture of the cloth is transparent. But the downside of the water-printing is that it can only be used on light-colored clothes. After wearing it for a long time, the color vividness of the pattern will decrease. What if I encounter dark fabrics? Then you can only cover the color of the cloth bottom, you need a glue that has filling ability.
Second, the glue printing. Glue printing can be compared to oil painting. The printed coating is a glue. This is covered. Because the glue is made of titanium dioxide combined with polyurethane. It's like oil painting. Graffiti can be done anywhere on any canvas. So the glue print can be adapted to the fabric of all T-shirts. No matter what the color of the shirt is, it has no effect on the glue printing. Ability to restore the color of the entire pattern. Since the glue is filled with texture, it involves air permeability. Because the glue is printed, there will be a layer of gel. Therefore, it is not suitable for large-area printing. What if you want to have the breathability of the water slurry, but you need to print on the dark fabric?
Third, print. The color of the cotton cloth is dyed. The principle of the printing is to destroy the dyeing of the cloth itself, and then dye the color attached to it. After the print is made, there will be no gelatinous texture of the glue, similar to the water slurry, soft, breathable, and can also be done on dark fabrics. The downside is that the cost is relatively high and the loss is relatively large.
Polyester printing mesh, but also a lot of other special printing process, combined with the pattern design, can make a lot of fun special effects. Such as luminous, reflective, fluorescent, pearlescent, thick board, suede foaming, flocking, photochromism, temperature discoloration, various lasers, colorful reflections, etc.
