The printed product has poor gloss and is not bright. In addition to the paper factor, it is mainly due to excessive ink dilution, resin precipitation and loss of connection. The dryness of the ink is slow or the absorption of the paper is too strong, causing the ink to penetrate the paper and make the printed product uneven and dull. Light. Approach: (1) Add new ink or add light linking material to the ink. (2) Change to high-gloss ink or paper with poor absorption. (3) Add some desiccant appropriately. (4) The printed products can be treated with varnish. [Related Links] Another manifestation of the poor gloss of the printed matter is "whitening". This failure is mostly in the process of volatile dry printing ink printing. A transparent white ink film layer appears during the rapid evaporation of the solvent after high-speed printing. This phenomenon is sometimes temporary, but most may be persistent. This is due to the cooling (device) blowing or air cooling to the dew point near the printing graphic ink film being dried, that is, absorbing the weight of water (vapor) and returning to the graphic ink film to condense. In addition, the solvent or pigment water in the ink system will also cause the gloss of the printed graphic ink film to be poor. The prevention method is: adjust the solvent used in printing ink, reduce the amount of solvent that evaporates quickly, and control the relative temperature in the workshop air to be below 65%.
