Before using digital printing equipment, you should first familiarize yourself with the paper manual to understand its requirements for the paper, that is, what standards are included in the applicable paper, and what are the compliance parameters of each standard.

Usually, the paper that meets the standard needs to meet the three standards of paper type, weight, filling and pulp. This requires a comprehensive inspection of the paper. The inspection indicators include the following three points.

(1) Paper type. Through hardness, resistance, the characteristic difference on both sides, moisture content, ash content (the content of other components except pulp), packaging and storage conditions, post-press curvature, fixing (the ability to permanently absorb ink color), paper feeding conditions 9 items Indicators to check whether the paper type meets the specified requirements for digital printing presses.

(2) Quantity of paper. Usually, the user manual will have the basic weight range of the paper that can be used by the printing press. Using lighter (or thinner) paper can cause paper tears, cracked paper feed holes, or incorrectly loaded paper. Using heavier (or thicker) basis weight paper may cause misfeeds (failed paper feed) or smudges, falling out of the feeder, etc., all because the paper is too stiff. To avoid these problems, make sure to use paper that meets the basis weight regulations.

(3) Paper fillings and pulp. If the amount ratio of filler is too high and the pulp composition is too low, the hardness of the paper is not appropriate even if the basis weight of the paper meets the specification requirements. This can also cause the printer to jam, incorrectly fold or wrinkle. Therefore, it is necessary to strictly follow the paper manual of the digital printing machine and use the paper that meets the scope of the application of the digital printing machine.
