The history of printers The theory of inkjet printers was invented in the late 1960s, and it was not until the 1970s that the world's first commercial inkjet printer was produced. Before the 1990s, only a few countries such as the United States, France, Britain and Japan could produce such inkjet printers. Since 1992. The first domestic manufacturer of inkjet printers ended the monopoly of foreign products.
Small character printer
The printer uses the ink to be electrically deflected to deflect the ink out of the normal flight path, to the surface of the work object, and to control the position of each ink droplet by the amount of charge charged to the ink droplet. Usually, the ink droplets only change in the vertical direction, and the ink and the nozzle must be moved relative to each other to form the material we want to print.
The printer logo has the following advantages:
Non-contact
Because it is sprayed ink, it does not need to be in direct contact with the surface of the workpiece, and will not damage the surface of the printed matter.
2. Fast speed
Take the production of soda cola as an example, it can reach more than 1000 bottles per minute.
3. Easy to edit and modify the contents of the printed materials
Because it is computer-controlled data, it can be easily changed. The data content can include erratic data such as date and time, serial number, and batch number.
4. The surface material of the application is extensive
The printer is available in a variety of inks, from paper, plastic, metal, glass, to hard surfaces or to soft, fragile surfaces.
Large character inkjet printer
The principle of a large character printer is completely different from that of a small character printer. The way in which the ink is ejected is to use each individual valve to control the switch.
If it is a 7-point nozzle, there are 7 independent valves to control the printing font size, which is generally applied to the outer box, outer packaging or large workpieces, such as crude water pipe or asbestos board, heat insulation board, etc. Workpiece. Its advantages are similar to small fonts, except that it works at a slower average of 60m/m, depending on the breadth of the printed font.
The large character inkjet printer was first developed and manufactured by WellDraw. It is generally divided into LC-07 and LC-16 models. The ink is divided into water, alcohol, ketone and high temperature materials.
High resolution jet printer
The high-resolution inkjet printer belongs to the DOD-type inkjet printing in principle, and generally uses the XAAR inkjet printer nozzle, which is characterized by high resolution of the printed content.
Laser printer
The laser printer uses a software to deflect the laser beam and use the high temperature of the laser to directly burn the surface of the product to be identified to form a font or pattern.
Application of coding technology
Nowadays, the application of identification technology is gradually deepening into every corner, especially in the industrial application, the application complexity is greatly increased, making the identification an indispensable part of the production in various industries.
Manufacturers identify their products mainly for the following reasons:
1. Conducive to product identification.
By labeling the product with special logos, brand names and trademark patterns, the products can stand out from the competition and increase the brand's popularity.
2. The need for product tracking records. The batch number, shift or production date of the product is directly printed on the product, so that each product has good traceability, which greatly facilitates the quality management of the enterprise and the regional management of the product.
3. Prevent counterfeiting. Manufacturers can often prevent and suppress counterfeiting by identifying the products, and the application of new technologies enables those legitimate manufacturers to stay ahead of the counterfeiters.
4. Increase the added value of the product. Marking a trademark or manufacturer's name on a plastic pipe means a promise that consumers generally consider to be a product of a company whose quality tracking is relatively complete and responsible for product quality.
5. Improve production efficiency and reduce production costs.
Food Additives are substances added to food. Some additives have been used for centuries. With the advent of processed foods in the second half of the twentieth century, many more additives have been introduced, of both natural and artificial origin.
The advantages of food additives are these followed:
1. Improve the appearance of food.
2. Keep and enhance the nutrition value of food.
3. Increase the variety and conveniences of food.
4. Miantain freshness and prolong shelf life.
5. Provide leavening or control acidity and alkalinity.
