Printing problems and solutions of gold silver ink

1. What should be paid attention to when printing other colors on the surface of gold ink or silver ink

answer: pay attention to the viscosity of the ink. As the hue of general gold and silver ink is not high, printing technology 7 The full digital, 3-loop (force, deformation, displacement) control system based on Neuron Adaptive PID algorithm can increase the ink discharge to improve its color. However, this will increase the viscosity of the ink and the drying time will be longer, which will affect the coverage of the next color. Therefore, some gold and silver inks with higher hue should be selected. Most enterprises in China have more foreign plastic extruders equipped with appropriate ink volume for printing. At the same time, the printing speed should not be too fast

2. How to make black words full color (not gray) when printed on the surface of gold ink or silver ink

answer: black ink with high hue should be selected. If possible, it is better to print twice to allow time for the gold and silver ink to dry

3. How to prevent reflection (over bottom) when printing gold and silver ink

answer: This is related to the excessive amount of ink and the quality of the paper. It should be printed on paper of appropriate ink quantity and high quality. In addition, many companies use a kind of gold and silver ink to print on different kinds of paper, which is incorrect. As different kinds of paper have their own printability, appropriate ink should be selected to match. The supplier can be consulted for relevant information

4. In many cases, in order to catch up with the goods, the printing technician will add "quick drying agent" to the gold and silver ink to speed up the drying. Is this feasible

answer: improper additives will affect its color performance and dryness. Generally, in the process of ink manufacturing, the drying agent is added after the pigment is mixed with the liquid medium. Some gold and silver inks mix the pigment and the liquid medium in the form of oxidation. Therefore, they have high compatibility and good drying performance

5. What effect will the pH of the bucket water have on the printing of gold silver ink

answer: if the pH of the bucket water is too acidic, i.e. it is lower than 5, the print will be difficult to dry, and it should be between

4. In many cases, in order to catch up with the goods, the printing technician will add "quick drying agent" to the gold and silver ink to speed up the drying. Is this feasible

answer: improper additives will affect its color performance and dryness. Generally, the test repeatability of ink manufacturing 1 is low, and the test piece fragment manufacturer is eliminated. In the process of ink manufacturing, the desiccant is added after the pigment is mixed with the liquid medium, while some gold and silver inks are mixed with the liquid medium in the form of oxidation. Therefore, they have high compatibility and good drying performance
