Permanent Printable Sticker Paper Pre-press process of self-adhesive label

Pre-press design requirements for self-adhesive labels

(1) Understand the process route.

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

2. Self - adhesive label printing for embossed resin

Film production with computer typesetting, with laser phototypesetter typesetting. Usually, negative images are used to see positive negative images. The density of the light transmission part of the film is less than 0.05, and the density of the light blocking part is more than 3.0. Plate making process is: exposure _ rinse a drying after exposure.

3. Flexographic resin version of sticker label printing

Flexo has the characteristics of high elasticity, high printing resistance, high resolution, to make high quality printing plate, in addition to high quality plate materials also need high quality plate technology and plate making equipment. At present, the better plate materials include the Ceri plate made by DuPont in the United States and the plate made by BASF in Germany, etc., which are composed of three parts: polyester protective layer, photosensitive resin layer and polyester supporting film. Photosensitive resin layer is attached to the polyester support film, to ensure the stability of the size, and then covered with a layer of polyester protective layer, polyester protective layer and polyester support film card protection plate in the handling, cutting and back exposure process to avoid damage.
