Identification of printing paper

Good paper gives people a very comfortable feeling. The surface of the paper is free of grass, sand, cracks, holes, and other problems. The paper is not necessarily white, but the hand feels very good, and it feels thin and even and smooth. Delicate, not rough, when touched on the paper with the palm of your hand, there is the same feeling that touches the surface of the glass, soft and quite scratched, such paper is generally used in printing tickets and other aspects.

In addition to the eye, the method of identification of printed paper can also be performed by means of paper shake and ink blotting. Shaking paper is to pick up the paper and gently shake it. If it flutters and sounds like a newspaper, and it feels stiff like a newspaper, then the paper must be crisp and poor in flexibility. If it is used in printing calligraphy and painting, The books and publications should have poor results.

If the paper is fluffy and soft, not brittle and the sound is small, it has a box in the middle and a soft feeling in the hard. The ink test paper is filled with ink after the brush is filled with ink, gently point on the paper, the paper reaction is fast ink absorption, uniform diffusion, ink edge is not jagged, easy to control, fast dry, and other ink completely penetrated After the paper fiber, the second time, after the ink dry, there was a clear layer effect and the ink was clear.

Paper with poor paper spread unevenly, either a large piece, poor water absorption, ink penetration into the fiber, this looks very smooth, but the printing effect is not necessarily good, or a large piece, not easy to control, and the edge of the ink Jagged traces appear. This kind of paper is poor, and the thin paper and paper are poorly constructed. Therefore, choosing a good paper quality is very important for the control of print quality.
