In ancient times, the application of chemical etching machine technology was accidental. One day, people accidentally spilled acid on the metal and found that the acid could corrode the spilled area and bite off. The bitten area and the non-bitten area formed It has a three-dimensional feeling. Then

After the etched magnesium plate was put on the market in the early 1970s, its superiority was recognized; later with the vigorous development of the printing and packaging industries, it was popularized and widely recognized in the field of high-end hot stamping printing; in recent years, due to st

1. Chemical conversion treatmentThe chemical conversion coating of magnesium alloy can be divided into chromate series, organic acid series, phosphate series, KMnO4 series, rare earth element series and stannate series according to the solution.The traditional chromate film has a dense structure wit

As we all know, hot stamping can improve the grade of paper packaging products and increase the added value of products. It is a popular post-printing process. Temperature, pressure, and speed are the three core elements of hot stamping. If they are not well controlled, it will greatly affect the qu

　　 Magnesium alloy etching plate and zinc plate, copper plate are mainly compared from the following aspects:1.plate making time　　 So the plate making process of the hot stamping plate is basically the same. The main difference is the etching time. With the same pattern and the same required etching

Gravure printing is to fill the entire surface of the printing plate with ink, and then use a special scraping mechanism to remove the ink in the blank part, so that the ink only remains in the cells of the graphic part, and then under greater pressure ,Transfer the ink to the surface of the substrate to obtain printed matter.

Hot stamping is already a very common part of printed matter, and the technology is also very mature. Here are five hot stamping methods for you. These five processing can be used in printing, and each has different characteristics. You can choose different hot stamping methods with different design

1. Current status of etching processIn the traditional etching process, many production links have pollutant emissions. From film output to drying, there are large and small pollutions in all steps. Etching is a heavily polluting industry. If it is allowed to discharge waste water, it will seriously
