No matter how printed, the basic requirements of printed matter on paper are nothing more than weight, thickness, brightness, opacity and smoothness. In these aspects, digital printing is no exception. However, sometimes special digital printing machines also put forward some specific requirements for paper.Different Requirements For Paper In Digital Printing

        For example, digital printing machines, copiers or desktop printing machines using the principle of electrostatic printing are the most common This kind of printing equipment requires the paper to have good dimensional stability, low flexibility and low wrinkling under the environment of temperature and humidity changes. At the same time, it also requires appropriate wear resistance, surface conductivity, sufficient stiffness, and less paper wool or dust in the printing process.Different Requirements For Paper In Digital Printing

       In addition, the paper should also pay attention to the printing quality. Since the electrostatic printing principle is applied for printing and the pigment is used to replace the ink, the electrical properties of the paper, such as resistivity and dielectric constant, should be controlled at an appropriate level. It should also be borne in mind that the moisture content of the paper has a great impact on the performance of the paper and its printing performance.Different Requirements For Paper In Digital Printing

       The consistency of the quality of the printed matter printed by the electrostatic printing principle depends on mastering the correct machine parameters, but the uniformity of the paper is also very important: the distribution of fibers or fillers in the paper must be uniform, and the smoothness of the surface is also crucial to the quality of the color transfer, especially for those models where the paper surface is in close contact with the color. Different Requirements For Paper In Digital Printing

       The color reaches the paper After the surface is on, it is mostly fixed by hot pressing. Therefore, the smoothness, surface chemical properties and heat treatment properties of the paper surface must also be controlled at an appropriate level. The stiffness of low gram weight coated paper shall be required to prevent bending on the hot pressing roller.Different Requirements For Paper In Digital Printing

         The change of environmental humidity during transportation, handling and storage of paper has a great impact on the digital printing quality of electrostatic printing principle. Therefore, air conditioning control shall be applied to relevant warehouses and printing workshops.Different Requirements For Paper In Digital Printing

       Digital printing using ink-jet technology is very different from digital printing using electrostatic principle. Because 50% – 90% of the ink-jet is solvent-based, and most of the pigment is solid polymer particles with pigment. The liquid performance of the ink used in ink-jet technology has requirements for the surface absorption and absorption of the paper, including:Different Requirements For Paper In Digital Printing

       after the ink drops are sprayed on the paper, the pigment should remain on the paper without expansion Therefore, inkjet digital printers have high requirements for paper surface properties, pore structure, chemical composition and mechanical properties, and not all inkjet printers or inkjet materials are the same.Different Requirements For Paper In Digital Printing

      The paper suitable for inkjet digital printer must also be wrinkle free, flexible and stable in size as far as possible, and its surface wear resistance and electrostatic effect must be controlled within the ideal range in order to ensure good printing performance.Different Requirements For Paper In Digital Printing

      In short, although most of the paper used in many digital printers are ordinary offset printing paper, there are still certain requirements for paper for some digital printers with special structure or technology under certain specific conditions. Different Requirements For Paper In Digital Printing

     It can be said that so far, no paper can adapt to all digital printers, which should be noted.Different Requirements For Paper In Digital Printing
