Permanent Printable Sticker Paper is a pre-press process for label printing

1. The prepress design requirements of self-adhesive labels are as follows:

(1) Understand the process route.

(2) In the application of color, spot color should be used more to make up for the lack of four-color printing, and the color should be simple and bright.

(3) the same color bright tone and the field should be separated for plate making.

(4) Lines should not be too thin, and text should not be too small.

(5) The level is used to emphasize the middle tone, high light and dark tone level to be flat.

(6) When printing the label, the direction of the label and the position of the label should be considered.

2. Self-adhesive label printing of relief resin version

Film production with computer typesetting, laser typesetting machine. Usually, the Yin picture is used to see the Yin picture of the positive character. The density of the light transmittance part of the film is less than 0.05, and the density of the shading part is greater than 3.0. The plate making process is: exposure - rinse - drying - exposure.

3, flexo resin version of the sticker label printing

Flexible version has the characteristics of high elasticity, high printing resistance and high resolution. To make high-quality plates, in addition to high-quality plate materials, high-quality plate-making technology and plate-making equipment are also required. At present, the better version of the United States dupont version, the version of the German BASF company, etc., by the polyester protective layer, photographic resin layer, polyester support film three parts. The photosensitive resin layer is attached to the polyester supporting film to ensure the stability of the size, and then covered with a layer of polyester protective layer, polyester protective layer and polyester supporting film card to protect the plate in the process of handling, cutting and back exposure to avoid damage.
