Paper Products Packaging and Printing Troubleshooting

2018-12-26

For a paper product packaging and printing factory, under the premise of guaranteeing the quality of the packaged printing products, printing out qualified packaging boxes with poor-quality pasta paper is undoubtedly a good way to increase profits. However, the paper with poor paper quality generally suffers from falling powder, pulling hair, and blistering. For this situation, combined with work experience, introduce several processing methods.

1. When the paper is fluffed, blisters, or lightly powdered, the paper can be air-pressed before printing. Under pressure, some of the paper and paper dust are adsorbed on the blanket. The role of powder phenomenon. At the same time, after the paper fiber absorbs water and expands, under the effect of pressure, the structure of the paper becomes more compact, so that the printability is improved. In addition, the surface tension formed by the water molecules filled in the capillary pores on the surface of the paper will have an effect of adsorbing the coating layer on the surface of the paper, and may also achieve the purpose of changing the physical properties of the paper and improving the printability.

2. When the paper is lathered and blisters is relatively serious, which affects the quality of the printed product, adding about 3% of the retreating agent in the ink will help the packaging and printing factory to solve the problem. However, special attention should be paid to the amount of retreating agent should not exceed 5%, otherwise it will not only affect the print gloss, but also easily lead to dirty version.

3. When the paper is out of powder and the nap is serious, you can also print a layer of primer on the surface of the paper, and then dry it before printing. Due to the improvement of the permeability of the paper surface, the quality of printed products, especially the gloss of printed products, will be significantly improved.

In addition, the spring in the south of the spring is humid, and the tissue paper printing and printing factory easily absorbs moisture and forms a flounced edge, resulting in paper wrinkles. When rubbing paper can not solve the problem, under the pressure conditions, so that the paper in the printing press several times before printing, so it can solve the problem of paper folding, peers may wish to try.
