Double-sided and reverse labels

Different from the double-sided label printed on the adhesive, the double-sided label means that the double-sided label is printed on the transparent film to achieve the purpose of double-sided label appearance. There are two commonly used printing methods.

More than one ink printing. First, the reverse graphic is printed on the transparent film material (OPP, PET) in reverse color sequence, and then white ink is printed on the graphic surface to cover the graphic. The ink surface is printed in the normal color sequence on the surface of the white ink to protect the ink, and finally the coating process is used. After the label is discarded and discarded, a double-sided label is formed.

Multi-layered ink printing is suitable for printing on web presses and printing with uv inks. Due to the large number of printing colors, it is often necessary to complete two printing operations (such as a six-color printing press and two printing twelve colors). For example, on a platform labeler equipped with a UV rotary screen printing device, double-sided labels can be printed in one shot.

2 paper plastic composite printing. The principle of printing is the same as above. The difference is that instead of printing white ink, the reverse printing image is covered with a white paper with a laminating principle and covered with ink. Then print on the paper to complete the double-sided printing. Paper-plastic composite printing can be carried out on various types of labeling machines. For example, it can be processed twice on an intermittent labelling machine.

The reverse label is a special case of the double-sided label, ie, after the reverse image is printed on the film, only the white ink is printed or the white paper is overlaid, and printing is no longer performed. In addition to double-sided labels can be processed in roll format on the label machine, it can also be processed in a single sheet format. The commonly used method is screen printing.

Double-sided labels are used on transparent bottles or glass, such as cosmetic bottles and labels on windows in the car's cab.
