Self-adhesive materials - double-sided labels and the printing of graphics on the adhesive double-sided labels are different, it refers to the transparent film printed several times, to achieve the appearance of double-sided labels for the purpose of the commonly used printing methods are two.
① Multiple ink printing. First, in the transparent film material (OPP, PET) according to the reverse color sequence printing reverse graphics, and then print white ink on the surface of the graphics, cover the graphics. On the surface of the white ink according to the normal color sequence printed on the graphic, in order to protect the ink, and finally using the laminating process. After the label is die-cut and rejected, it forms a double-sided label. Multi-layer ink printing is suitable for rotary presses, using UV ink printing. Due to the number of colors printed, often need to be printed twice to complete (such as six-color printing machine, two printing twelve colors). Such as in the platform equipped with UV rotary screen printing device labeling machine, double-sided labels can be printed once.
② paper-plastic composite printing. Printing principle as above. The difference is that the reverse printing is not printed on the graphic white ink, but the use of laminating principle overlay white paper, covered with ink. Then printed on paper to complete the double-sided printing. Paper-plastic composite printing method can be carried out in various types of labeling machines, such as in the intermittent small labeling machine can be processed twice to complete. Reverse labeling is a special case of double-sided labeling, that is, after printing on the film reverse graphics, only printed on white ink or covered with white paper, no longer printed. Double-sided labels in addition to the labeling machine in the form of a roll of simple processing, but also in the form of a single sheet processing, commonly used methods for screen printing. Double-sided labels are used in transparent bottles or glass, such as cosmetic packaging bottles, car cab windows on the label.
