9 major features of fully automatic screen printing machine
2024.10.09
The fully automatic screen printing machine can be used for various plastics, cosmetics, packaging boxes, metal plates, scale plates, acrylic, organic glass, electronic products, household items, stickers, leather transfer paper. Various types of cups, barrels, glass, baseball bats, wooden boards, etc. It can also be printed on flat and curved objects for aesthetic and high-quality efficiency. The fully automatic screen printing machine has the following characteristics: 1. Multi station printing with fully automatic electric eye alignment, computer-controlled, automatic color code detection, and automatic shutdown in case of abnormalities. 2. Using CNC motors, the printing and ink return speeds can be set in sections as desired. 3. Using CNC motors, the printing and ink return distances can be freely set with data. 4. Automatically calculate the number of prints and set the number of prints to automatically shut down. 5. Optoelectronic control of feeding and receiving can avoid scratching the surface of the substrate and improve printing quality. 6. Using Japanese brand precision adjusters, the electric eye has high precision. 7. The fully automatic screen printing machine is equipped with dust removal rollers, which can remove dust from materials. 8. The fully automatic screen printing machine is equipped with an off screen function to prevent sticking to the screen when printing large areas of base color and printing glue. 9. The fully automatic screen printing machine adopts a three-stage suction device, which can adjust the strong wind, weak wind, and shutdown according to the requirements of the printing material.
Five common faults and troubleshooting methods of gravure printing machines
2024.10.09
Using a gravure printing machine, there are traces of a scraper on the scratched printed material. The elimination method is to use clean ink without foreign matter mixed in for printing. Adjust the viscosity, dryness, and adhesion of the ink. Use a scraper and adjust the angle between the scraper and the printing plate. Fault 1: When using a gravure printing machine, there is a periodic change in ink color on the printed product due to uneven ink density. The elimination methods include: correcting the roundness of the printing plate cylinder, adjusting the angle and pressure of the ink scraper, or replacing it with a new ink scraper. Fault 2: Imprint smudging, fuzzing, and uneven layering of printed images, as well as the appearance of burrs on the edges of graphics and text. The methods of elimination include: removing static electricity on the surface of the substrate, adding polar solvents to the ink, increasing the printing pressure appropriately, adjusting the position of the ink scraper, etc. Fault 3: When using a gravure printing machine, the phenomenon of blocking ink drying up in the mesh holes of the printing plate, or the mesh holes of the printing plate being filled with paper wool or paper powder, is called blocking. The elimination methods include increasing the solvent content in the ink, reducing the drying speed of the ink, and using paper with high surface strength for printing. Fault 4: Ink overflow causes spots to appear on the surface of the printed material. The elimination methods include adding hard ink adjusting oil to increase the viscosity of the ink. Adjust the angle of the ink scraper of the gravure printing machine, increase the printing speed, and replace the deep mesh printing plate with a shallow mesh printing plate. Fault 5: When using a gravure printing machine, there are traces of a scraper on the printed material. The elimination method is to use clean ink without foreign matter mixed in for printing. Adjust the viscosity, dryness, and adhesion of the ink. Use a scraper and adjust the angle between the scraper and the printing plate.
The four main characteristics of special printing
2024.10.09
1. The specificity of printing equipment The particularity of the printing process determines the specificity of the equipment used. Such as stereo cameras, digital cameras, holographic cameras, special plate making equipment, printing and embossing equipment, as well as post press processing and handling equipment used in special printing. 2. The relativity of concepts The concept of special printing has great relativity. It is a printing branch developed on the basis of general printing technology using the achievements of general printing technology. If there were no advances in general printing technology, there would be no emergence and development of special printing. Therefore, the two cannot be completely separated, let alone opposed. 3. Diversity of substrates The diversity of printing materials is mainly manifested in three aspects: * *, in addition to paper, printing materials also include cardboard, corrugated cardboard, metal, glass, fabrics, synthetic resin fibers, etc; Secondly, the printing surface is not flat, but has curved surfaces, rigid surfaces, elastic surfaces, and molded products; Thirdly, in addition to conventional specifications, there are also various size specifications for the substrate. 4. The particularity of the printing process It is the main feature of special printing. The main manifestation is the particularity of printed materials or printed products throughout the entire production process, such as the printing principle not only including pressure printing, but also including pressureless printing; The plate making method and materials used are different, and the plate making process is also different; Post press processing does not refer to book binding, but mostly refers to processes such as coating and polishing.
