First, pre-press processing, many customers orders are designed to offset or gravure-based approach, this manuscript if the use of flexible printing to complete the case, proofs are often a lot of quality problems, such as color is not in place, level is not obvious, such as a hard edge. Therefore, to solve the problem of timely communication with customers is essential.
Secondly, Flexible Plate The choice must shop around. Printing companies need to partner with several well-known plate-making, the use of the plates, cable version of the production level of the transition, the increase of network compensation, the stretching rate of plate full discussion of such issues, collate and analyze these data to develop a standard reference for the daily production. The data of this Management Not only conducive to the production, but also good quality parameters can be controlled to avoid human interference, reducing the production malfunctions.
Again, due to Label Printing special, narrow flexible letterpress printing equipment compared to other types of flexible printing equipment is concerned, there are prominent features, narrow flexible printing equipment is not only simple, high print quality and operational efficiency, and the combination strong, which means a greater variety of products can do and more competitive.
Good equipment also need to correct operation, reasonable maintenance, to maximize its effect. In the narrow use of equipment, the biggest obstacle is not technology, but technology issues.
1. Ink quit and easy drop
Bad for ink drying problems, the solution is to use 9kW of UV drying equipment, it is easier than 2kW lamp, more rapid drying. Easy to fall off of the problem encountered in ink, should be ink suppliers, raw material suppliers to analysis, if it is not good ink adhesion, can be added Additive If the printing surface adsorption is not good, the need for corona treatment.
2. Static electricity Static problem is often encountered in production, in particular, printing labels, you need to install the device package static device, but also to shop temperature and humidity controlled strictly. Particularly in the mold label and film production class label products to static electricity, the printing is better than dust.
3. Good squeegee effect Flexible printing process, the blade and Anilox roller Synchronous transmission, prone wire cutter, that is printed ink on the label pulled out of the traces, on the ground in some places the color reflected the color of light at around this time the blade should be adjusted to the best angle. The choice of the scraper, the scraper blade mostly imported through the carbon burning treatment of ink is better. There may be due to traces of ink ink itself prone to bubbles formed in the roller marks due, then need to add some appropriate additives.
4. Mexican bars Bars ink on the label is often the plate cylinder and impression cylinder on the gear teeth are not round, or plates have indentations, now need to replace the plate cylinder gear.
5. Screen lines Print screen lines from the point of view, the maximum offset and gravure printing lines higher than the soft, flexible printing ideal line screens of 150 lines / inch or so, if more than 175 lines / inch, will increase flexo plate making and printing difficulties, especially in the field and the network cable on the same edition, the field part of the ink volume, ink and so easy to cause trouble blocking roller, will shorten the life of plate. In addition, cable processing, flexible printing and offset printing, gravure entirely different offset, gravure of the network can be tapered to zero, while the flexible printing the minimum can only be 2%.
Label market for flexible printing technology provides a development stage, to enhance the quality of flexo printing, reduced costs, increased process flexibility, and promote a flexible printing market. With UV technology, Environmental protection Increase awareness, reduce equipment repair time, users UV flexo printing technology gradually increase the degree of acceptance. At the same time, users increasingly value the combination of a variety of printing technology to meet the needs of label market diversification, and hence the I am an expert from China Building Materials, usually analyzes all kind of industries situation, such as zune car kit , ipaq car cradle.
