Performance requirements for digital printing paper
Digital printing paper must meet three requirements: 1 paper-feeding, that is, the ability of paper to pass through the printing machine smoothly, especially in the double-sided printing and feeding process, the dimensional accuracy is very important for smooth paper feeding, and The smoothness of printing paper has a great influence on the paper feeding property; 2 ink transferability, that is, the ability of printing paper to accept ink or toner; 3 resistance, that is, after the final formation of digital printing, in use The tolerance of printing paper to various disadvantages.
In addition, the whiteness, porosity, thickness, stiffness, coating or processing methods of digital printing paper will also affect the final image restoration quality, and should be carefully selected according to the final effect requirements. At the same time, the direction of the silk thread of digital printing paper should also be given special attention. It should be traced from the end use of digital printing products to the post-press processing stage, printing process and paper feeding, and carefully selected according to needs.
If an electrostatic digital printer is used, since it is based on the principle of electrostatic imaging, the conductivity of the printing paper must also be considered. Among them, controlling the moisture of printing paper is one of the key factors. The moisture of the printing paper is low enough to maintain its good electrical conductivity and facilitate the transfer of toner. In addition, the type of pulp, filler, and fiber orientation of the printing paper also affect the conductivity of the printing paper.
Matching of digital printing paper with digital printing equipment
It is not difficult to choose a printing paper that matches digital printing equipment. Most digital printing paper suppliers provide customers with a detailed list of matching equipment, and digital printing equipment manufacturers also provide customers with a list of matching papers. In comparison, paper optimized for a specific ink or toner has better printing results than paper optimized for different printing processes. That is to say, it is easy to obtain a better printing effect by selecting matching papers according to the list provided by the digital printing equipment manufacturer.
In digital printing, the effect of the paper coating is to prevent excessive penetration of the ink, thereby avoiding unclear printed images. The specially processed digital printing paper prevents the ink from penetrating into the paper and leaving it on the paper surface, thus ensuring a wide color gamut, high density, high definition of the printed image, and preventing bleeding and offset. Therefore, many digital printing equipment manufacturers require the use of specially processed paper.
To expand the reach of digital presses for paper, many digital printing equipment manufacturers have reduced equipment dependence to reduce the dependence on special paper. For example, processing methods such as on-line coating can meet the needs of printing companies to use plain paper in digital printing. In addition, digital press manufacturers have expanded the range of paper for digital presses by developing new inks and toners and new methods.
