Printed matter is often used in our daily life. Examination papers printed in student days, photocopied papers, resumes printed in job hunting, award-winning certificates duplicated, contracts printed in work... All of these need us to print. Some of these listed above can be done by a simple roadside graphic shop, while others require a printing plant to complete.
Now let's talk about the problems we need to pay attention to in printing process.
1, when printing products that are not easy to dry, the height of stack prints should not be too high. After the ink layer is fixed, the printing pad lightly jitter, which can increase the contact between the ink layer and the air, and accelerate the drying of the ink.
2. When the printing width increases, the position of the original printing paper is easy to appear the phenomenon of insufficient pressure.
3. In the case of printing products with higher requirements and less quantity, we can consider reducing the number of printing plates and printing with smaller size of paper to improve the accuracy of overprinting.
4. Designing the layout as far as possible to avoid the same area of the positive and negative are large ink printing, and to ensure the color of the case, as far as possible to reduce the supply of large ink area ink, in order to avoid blistering problems.
5. In four-color printing, a large area of black solid part plus about 30% blue, so that black solid ink thick, uniform and beautiful.
6, printing color sequence can be adjusted according to the color of printed page.
7. It is suggested that the paper feeding wheel and brush wheel should be placed as far as possible in the blank or light tone on the stamp to avoid the stain caused by the paper feeding wheel and brush wheel.
8, when the ink does not dry, it is possible to add isopropanol in the fountain solution to speed up the evaporation of water.
