Nowadays, large-scale self-adhesive label printing is mainly based on letterpress and flexographic printing, but the demand for personalized small-volume self-adhesive labels on the market is increasing, and tens of thousands of small labels are combined into six. Open and eight sheets of paper, only a few thousand, hundreds of copies, the web label printing machine appears to be incapable of printing such work.
In terms of printed products, small batch jobs require low cost and short delivery time; while product quality often requires bright color, and the layout of the dots is mostly. According to this situation, many small printing companies use a six-color monochrome offset press for four-color overprinting, which also achieved very good results. The combination has the following advantages.
1. Reduce printing costs
In offset printing, embossing, gravure printing, etc., offset printing is undoubtedly the lowest cost printing method. In the prepress process, compared with the complicated plate making process of the flexographic plate, the production, filming and printing process of the PS plate is a light road for the printing factory. From a technical point of view, after the printing companies have eliminated the printing, they have turned to offset printing, so there is no additional burden.
If a reel self-adhesive printing machine is used, there will be a loss of more than ten meters of paper when it is turned on. If the overprinting adjustment is not good, and the unit type printing machine has a long paper feeding line, the waste is greater. The offset press can use other papers as the master paper to save the self-adhesive material.
Offset plates are very low in price compared to embossed and flexographic plates and do not require much auxiliary material. When printing paper of different thicknesses, the printing pressure can be adjusted at will. From the operational point of view, offset printing technicians (leaders) are also easy to hire, and the technical threshold is not high.
The practice of the printing factory proves that the cost of printing small self-adhesive labels with offset printing machines can be reduced to “minutes”. If the processing is processed, even if the profit is calculated by “cm” or “mm”, there is profit.
2. Guarantee print quality
Different from the self-adhesive labels in Japan and other countries, China's self-adhesive labels are mostly rich in graphic activities, especially small batch labels, which often require colorful colors. Offset printing has an advantage in dot printing, and printing on the spot is not inferior. If you need to increase the thickness of the ink, you can use the advantage of overprinting to make secondary printing. Because it is small batch printing, time is completely guaranteed.
In addition, the use of offset printing and quick-drying ink, the addition of desiccant in the ink, and the method of powder spraying after printing can also effectively solve the problem of printing the stain and improve the printing speed.
3. Shorten the printing cycle
Short-run job printing emphasizes timeliness. If the pre-production process is complicated and the plate-making cycle is long, it will inevitably affect the delivery period. The offset printing cycle is short, and it is a suitable choice for short-lived label printing with complicated patterns and strong timeliness.
Of course, there are certain difficulties in printing self-adhesive materials with offset presses. There are two main points:
1) In the market, self-adhesive materials are currently sold in rolls, printed on sheetfed offset presses, and must be changed to flat sheets. If it is changed by the printing factory itself, it will take time and effort. In this regard, you need to ask the suppliers of self-adhesive materials to assist. In addition, the self-adhesive paper that has just been cut is curled, and needs to be flattened. After a long time of flattening, it is necessary to perform paper-making before printing.
2) The offset printing machine does not have a die-cutting unit. The printed self-adhesive printing sheet is not a finished product. It must be processed by a die-cutting machine for die-cutting. Die-cutting, such as elliptical, triangular or other special-shaped label products, requires an additional process. Working hours.
According to experience, it is recommended that the printing equipment be used in quantity, and the appropriate equipment should be selected to print the corresponding product.
