Trademark printing

A new type of printing, label printing, which appears in packaging printing, is the printing of main products such as product label signs. It is printed on a special composite paper, for commercial brand stickers, labels need to paste the convenience, in the back of the paper coated with a layer of adhesive, adhere to a layer of easily peeled wax coated release paper. Therefore, this method is also called sticker printing. After the printing, it is printed with a knife line, and the excess part is peeled off to leave a certain shape of the printed product on the release paper. When the product is used, the finished product can be peeled off and pasted directly onto the product or package. In addition to printing on paper, it can also be printed on aluminum foil. Color polyester film is self-adhesive printed matter for printing materials.

The production and printing process of composite paper is as follows:

Printing surface roll → single surface → coating adhesive → drying bronzing

→ Pressurized compound → print → die cut → finished product.

Release paper base paper roll→sprayed polyethylene film→coating anti-adhesive agent→drying

The printing surface paper generally uses 90 to 100 grams of coated paper, and after coating with glue, it is dried at a speed of one meter per minute at a temperature of 80 DEG C. The anti-sticking paper base paper generally uses 20 grams of chicken skin paper. After the anti-adhesion agent is applied, it is dried at a speed of one meter per minute at a temperature of 120[deg.] C. and then compounded with the printing surface paper.

The printing plate is made of letterpress photosensitive resin printing plate, printed with a special self-adhesive label printing machine, using round flattening, flat pressing and equal multiple printing methods, the printing machine uses web paper, one-time printing, hot stamping, composite plastic Films, cross-cuts, wind-up scraps, and cuts are shown in Figure 6-6.

Figure 6-6 Structure of a sticker printer

When the machine is printing, the direction of the paper is different from the same level of printing machine in which the printing cylinder rotates. Paper is axially moving.

The plate cylinder is rotated perpendicular to the paper feed direction. Every time the paper is moved on the printing table, the plate cylinder reciprocates once and prints in one color. In a few color printing, the paper must be moved several times on the printing table to complete the overprinting work. Afterwards, it can enter the gilding and laminating and die cutting.

Die cutting is performed according to the desired shape of the trademark pattern. The die-cutting device is a flat-flattening structure, and the depth of die-cutting does not cut the anti-sticking paper layer, but only cuts the printing surface paper layer, so that the printed product can still be rewound and cut, and the subsequent tearing work belt can be It is convenient.

When you use it, simply peel off the release paper and paste the logo on the product or other object. It has features such as easy tearing, firm adhesiveness, flexible use, and non-sticky products when torn off. It is now widely used in trademarks, signs, and labels.
