Plate Printing Technology Tips: Reduce Costs

In the pattern printing process, a pattern layout is often used to print the background color once, such as securities, trademarks, and decoration prints. The specifications of these products vary, and the number of prints is also very different, but the shading plate version can often be universal. Therefore, it is of positive significance to preserve the old printing plate for reuse and maximize its effectiveness. This is of great significance for improving economic efficiency and enhancing the vitality of stamp printing.

Due to the limitation of the number and specifications of some products, it is often necessary to use small-size paper for printing, and to remake a shading plate of a corresponding size and size, which is completely unnecessary because there are old versions that can be used. Some printers often cut the 8th edition into 9 or 12 open, or even smaller, prints. Although it is more cost-effective to do so, it can avoid the hassle of making a new edition. However, the old layout of small pages cannot be printed in large format, and it is only necessary to create a new version of a large plate. Therefore, adopting the “cutting method” to realize large-format small-format printing will increase production costs and cause unnecessary economic waste.

In response to this situation, through deep exploration and practice, the traditional production methods have been changed and innovations and improvements have been made to the printing technology of the “Large Edition Small Printing”, which not only maintains the same old shading specifications. And save money effectively. When the transfer is less than the original size of the format, using the necessary "strain" measures, you can make the extra layout does not stick to the ink, do not contact the packaging lining, ensure normal printing, receive a good printing effect.

According to the theoretical concept of "Sanping" printing and the results of practice, it can be seen that the printing plate surface level is the basic requirement for receiving even ink and satisfying uniform printing pressure. Then, the soft thin solid resin plate, as long as breaking the "conventional" in the adhesive plate pad, can make the excess plate edge depression, will not get the ink roller inking, no imprint marks No damage to packaging linings. The need for printed layout, as long as the layout of the pad is appropriate, you can get a uniform ink, to meet the normal printing conditions. It can be seen that the principle of printing the "Sanping" printing plate leveling concept can be extended from the principle of printing "Sanping", thus providing theory and practice for the implementation of non-normal printing "Large Edition Small Printing" process. in accordance with. Based on the above-mentioned concept, the idea of ​​implementing a new process of “large-printing and small-printing” without cutting is produced. Through bold practice, it has achieved initial results in production.

For example, a 26 cm×18 cm product is to be printed on an 8 inch (format) printing plate with a size of 39 cm×27 cm. In order to fully maintain the original format, when loading, a 35cm/m white paper with a size of 26cm x 18cm should be cut first, and then it should be glued to the back of the 8 background pattern with appropriate area of ​​double-sided tape (two vertical and horizontal Edge alignment can be), then with a 39cm × 27cm format double-sided tape to the entire back of the printing plate (including pads whiteboard site) directly attached to the plate, and then pressed firmly. In this way, in the layout area of ​​26cm×18cm, due to the multi-pads of a whiteboard paper and a layer of tape, it is significantly higher than the non-printed layout area, so that the printing plate surface can be properly inked and embossed. The non-cushioned layout is slightly lower, so it has not been inked, there is a certain gap with the lining surface, and does not destroy the outer lining, which can meet the printing requirements and requirements of the "large print". Due to the soft texture and elasticity of the thin resin plate, the difference in plate offsets has achieved the purpose of adjusting the height of the layout and the conditions required for printing. In this way, it is possible to use the “large format” old storage version to print a variety of small-size products, to achieve a multi-purpose version, flexible and convenient, and greatly improve the utilization of the printing plate.

For many years, the universal shading chart of various specifications has been printed using the uncut version of the “large-printing” printing method, which saves the time for making plates, shortens the production cycle, and significantly improves the production efficiency and economic efficiency. Because the process is simple, fast operation, good printing effect, won the customer satisfaction.
