Good drying equipment, drying temperature should be determined according to the substrate, the size of the printing area, such as metal foil printing, drying temperature is above 100 ° C, and plastic film printing drying temperature is 60 ° C -80 °C is appropriate, the wind should be stronger than when printing with solvent ink, because in addition to the temperature, there should be strong wind, so that the ink can be quickly dried on the substrate. The plate is made of electro-engraving plate or laser plate. The plate depth is between 15μ and 20μ. This is because the ink is produced by tap water, and its boiling point is higher than the solvent. The shallow version can increase the printing speed and avoid water ripple. If the solvent ink is used for printing on the plate 35μ~40μ deep or above, water ripple will occur. However, if the ink is printed on the plate more than 25μ, there will be water ripple phenomenon. It is important to use a good plate.
