Analysis Of Printing Pressure And Paper Stripping Force        Analysis Of Printing Pressure And Paper Stripping Force 1. Printing pressure and paper deformation    Analysis Of Printing Pressure And Paper Stripping Force       Paper is a material with plastic deformation, and the plastic deformation characteristics of different papers are also different.Analysis Of Printing Pressure And Paper Stripping Force       Under the action of large printing pressure, the width and the length of the two corners of the trailing tip of the paper with large plastic deformation will expand slightly, resulting in inaccurate overprint, especially in the trailing tip of the paper.Analysis Of Printing Pressure And Paper Stripping Force         The greater the printing pressure, the more obvious the deformation of the paper. Therefore, when printing the same batch of products, the pressure of each color printing plate should be as consistent as possible, Analysis Of Printing Pressure And Paper Stripping […]

Printing Ash Balance Adjustment        In the packaging and printing industry, a variety of balance technologies are often needed.Printing Ash Balance Adjustment （1） Black plate effect         The ideal color reproduction only needs the superposition of Y, m and C primary color inks to combine thousands of colors and achromatic with different brightness. This is the three primary color reproduction theory. However, the three primary color ink can not print the ideal neutral gray and can not reach the required density (shown in Figure 4-4-2). Printing Ash Balance Adjustment       The field density of four-color printing is higher than that of three-color printing, which is due to the use of black plate compensation. In multi-color printing, it is in the state of wet pressing and wet printing.Printing Ash Balance Adjustment        When the ink layer is thick, it is not easy to dry, and it is easy to produce poor overprint. The a […]

Ink Over Emulsification And Its Preventive Measures        Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibuThe immiscibility of ink and fountain solution is the basic principle of offset printing, Ink Over Emulsification And Its Preventive Measures       but in the actual printing process, the complete immiscibility of the two cannot be realized.Ink Over Emulsification And Its Preventive Measures.Ink Over Emulsification And Its Preventive Measures       Because the printing process is dynamic, water and ink are squeezed by rollers, water rollers and ink rollers. Under the action of mechanical force, water and oil ink will inevitably infiltrate and disperse each other, so emulsification is inevitable, There are two emulsifying states:Ink Over Emulsification And Its Preventive Measures  Ink Over Emulsification And Its Preventive Measures       when the water is large, oil in water (O / W) is formed; when the water is […]

What Is The Difference Between Wet Offset Printing And Anhydrous Offset Printing?      Wet offset printing is the most common printing process in today’s printing industry. What Is The Difference Between Wet Offset Printing And Anhydrous Offset Printing?       The basic principle is to balance the water and ink in the printing area (printing ink) and non printing area (water) on the printing plate. The key is to keep the ink balance stable and controlled.What Is The Difference Between Wet Offset Printing And Anhydrous Offset Printing?       Anhydrous offset printing uses the non printing area coated with silicon coating on the printing plate to remove the ink balance control and avoid using water as the medium.What Is The Difference Between Wet Offset Printing And Anhydrous Offset Printing?       In terms of printing quality, printing without water makes the printing dot of anhydrous offset printing sharper and better performance. What Is The Di […]
