1) Do not use die-cut paper material die-cut film material, because the blade has been worn, is not suitable for die-cutting film.
2) When leveling die cutting, reduce the die cutting area as far as possible: especially for the full version, because the layout is large, the quality is difficult to guarantee.
3) When leveling die cutting, the pad should be replaced often, especially for the processing long plate, because the cut will affect the die cutting quality of the new plate label.
4) Often check the die-cutting quality, especially the automatic labeling label. To avoid a large number of quality questions. The detailed inspection method is to use a signal pen on the bottom paper to check the cut mark penetration of the bottom paper.
5) Die cutting large area, complex pattern label, to professional manufacturers to make die cutting version, so as to ensure the die cutting accuracy.
6) To keep the blade sharp, establish a file, remember the use of each die-cut version, so as to replace the blade in time.
7) Use small angles. Special blade die-cut film dry adhesive material, especially PET material.
Due to the improvement of the surface printing suitability of thin films and the improvement of UV drying technology, the non-paper labels (N. PaperLabel) Market trends are slowly forming. Facing the increasingly fierce competition in the label market, label printing factories should consider taking the road of diversified development and develop more varieties of label, such as thin film labels, without being disorderly or expanding the business volume.
The printing material adhesive label material is composed of surface materials, adhesive and bottom paper, according to the different surface materials, it can be divided into paper adhesive materials and film adhesive materials. The surface materials of film adhesive materials are polyester (PET) film, bidirectional tensile polypropylene (BOPP) film, vinyl chloride (PVC) film, polyethylene (courtyard) film, low density polyethylene (LDPE) film, etc.
The surface material of the film adhesive material is similar or basically the same as the film label material, but there are essential differences between the adhesive material and the film material in terms of printing adaptability. If it is necessary to use adhesive label printing equipment when printing film labels, we should pay attention to the impact of the change of printing materials on the printing process.
1) Because the adhesive material has the paper support, the stiffness is large and the size is not disorderly is good: and the film size is small, the size is not poor, in the printing to control the film tension, the printing press tension control system has a large adjustment range, tension is too small, the film in the printing process, the tension is too large, will cause the tensile deformation is not smooth, and even pull the material roll, affect the smooth progress of printing.
2) The film surface is faced with poor absorption of ink, so the film surface should be treated before printing, such as corona treatment, surface coating treatment and other printing methods.
