Colorful printed umbrellas will give people a romantic feeling, whether it is sheltering from the rain or dressing up, it is an excellent choice. The personality pattern on the umbrella can better show the personality. People can guess their personality through the personalised umbrella they hold in their hands. However, there are not many people who use the umbrella printing process. This article I bring to you today is about the umbrella printing process.
Generally, the most commonly used umbrella printing methods include screen printing, offset printing, digital thermal transfer, etc. Of course, each printing method has its own advantages.
First, let’s look at the steps of umbrella printing:
1. Obtain the original design of the umbrella surface;
2. Compose the picture and draw the splice line;
3. Set the cutting position and cut out the first draft of each splice;
4. Draw the splice board based on the splice original board;
5. Deform the bottom edge and height of the first draft of the splice plate according to the splice plate;
6. Deform the seam edge of the first draft of the splice according to the splice plate to obtain the splice draft;
7. Repeat steps 5 and 6 to deform all the first drafts of the splicing into a spliced draft;
8. Typesetting and printing;
9. Sewing products.
Next, let’s look at the process of umbrella printing:
The printing paste is composed of dyes or pigments, moisture absorbents, cosolvents, etc. and the original paste. The function of the original printing paste is to make the color paste have a certain viscosity and fluidity. It is made of hydrophilic polymer paste. Commonly used pastes include starch, starch degradation products (white dextrin and yellow dextrin), starch ether derivatives, sodium or ammonium alginate, and hydroxyethyl honey locust gum , Longjiao, cellulose ether, synthetic polymer electrolyte, etc. The emulsified paste made with water and emulsifier is sometimes used as the original printing paste. The original printing paste should have good stability to the chemical agents in the color paste, does not interact with the dye, has a certain adhesion to the fiber and is easy to wash off the fabric. The viscosity of the printing paste is determined by the nature of the original paste. If the viscosity of the color paste drops too much during printing, it is difficult to print fine lines, and if the viscosity is too large, the color paste will not easily pass through the pores of the screen.
At present, the most advanced printing technology is digital printing, which is the intervention of digital equipment, and the digital printing process with the intervention of digital equipment is very simple. Only the computer and close cooperation can complete the desired pattern printing of personalised umbrellas, foolish operation mode, Time-saving and labor-saving, the finished umbrella printing can be made quickly and easily without a lot of manual labor.
