Features of 9 Colors Logistics Label Flexographic Printing Machine
It is suitable for printing paper, paper board, high-grade self-adhesive label and so on.
A. The structure of the equipment is simple, easy to operate and maintain.
B. The wire processing ability is strong, the production cycle is short, and the work efficiency is high.
C. A new type of water-based ink and solvent based ink, non-toxic and pollution-free, fully meet the requirements of green environmental protection, and can also meet the requirements of food packaging. It is suitable for small or medium batch products.
D. The application materials are widely used, which can be applied to various materials, such as carton, paper, transparent film etc.
E. The printing quality is good, printing accuracy can reach 150 lines/inch, and the printed matter is rich in arragement, bright color and good visual effect, especially suitable for the requirement of packaging and printing.
During the normal printing operation of the printing press, the operator must constantly check the printing process and the printed matter. The use of the printed monitoring device is movable, and generally should be monitored in the position of the set of quasicross in the last color group or in the location of the points of the dot that is considered to be experienced. In the observation of the accurate monitoring of the printed set, we should pay attention to the accumulation of experience and refer to the printed sample so as to make the correct judgment. During normal production operations, we must constantly monitor the surface color, registration, ink volume, tension, ink viscosity and pH value of print, and find that problems need to be adjusted.
The cleaning of the rolls must be kept in the printing process. (no dry - solid ink is necessary to prevent the impact of the bearing, the printing and the life of the plate).
At the same time, keep the transmission gear clean. Because the splash ink drying in part will also lead to accurate alignment.
Generally speaking, the drying ability of printed material, printing plate and printing ink, the proficiency and operation process of printing operators, and the good condition of printing equipment determine the speed of printing machine.
To complete a good print, we must have a thorough understanding of the various materials used. The cooperation and selection of paper, ink, and subsequent processing should be communicated with the manufacturers in advance, and make each process work without affecting the quality of another assignment and strive to make the printed material perfect.
In the absence of test conditions, the printing materials should not be changed.
The qualified prints are the result of the coordinated work of the printing plate, the ink, the net roll and the flexo printer.
The printed products, samples and records are stored in the technical file to benefit the future summary of the experience and keep the same product in quality.
Quality identification standards for printed products:
1. The products are clean, no obvious dirty and incomplete.
