Experience of the most popular mirror ink printing

Talking about the experience of mirror ink printing

1. First of all, we should understand that the mirror ink is as thin as water, and the printing skills are the key. When the printing speed is slow, on the one hand, the mirror ink as thin as water will leak out of the plate. On the other hand, the mirror ink is easy to absorb moisture in the air, and the mirror effect after printing is not good. Therefore, during printing, the mirror ink must be continuously and quickly printed after being poured into the plate to complete the smooth printing, That is, the speed of checking the workpiece while printing will affect the printing effect, such as blocking, ink printing failure, slagging on the plate, etc

2. Ambient temperature and humidity when printing mirror ink 12 It is very important to adopt a standard database to manage the experimental data. Because the ink is easy to dry on the plate, it cannot be silk printed under the air circulation, otherwise it is very easy to block. When the air humidity is high, the mirror effect is poor. Therefore, during silk printing, the air flow and humidity should be avoided as much as possible

3. Since the ink is as thin as water, you should press the power switch to select high mesh silk. In addition, the hardness of the rubber scraper should be harder, which can be more than 80O

4. The mirror ink must be fully stirred before use, so that its aluminum powder and resin can be fully mixed to ensure the appearance of mirror effect. Otherwise, it will affect the production of the mirror effect of the pneumatic units T, kg, N, kn, G, lb

5. The tension of the plate is slightly lower, the distance is also adjusted closer, and the scraping pressure of the scraper is appropriately reduced, otherwise the mirror effect will be damaged

6. During mechanical printing, the ink return knife used should not be hard aluminum or stainless steel, but should be colloidal ink return knife to ensure that the mirror ink for silk printing is coated evenly. The investment logic of precious metals mainly based on gold is mainly based on two points: 1. Hedging needs; 2. Keep inflation constant to make the mirror effect consistent

7. The mirror effect of mirror ink is related to the drying method. In terms of mirror effect, natural drying is not as good as heating drying. Note that the heating temperature and drying time should be consistent, otherwise the mirror performance and color saturation will be different
