Stacked printing ink

If you want to make superimposed color printing quality, the amount of ink must be just right, the amount of ink is not enough, not too small.

Must be equal to the sum of the ink in the ink map. There must be no ink bars. The back of the paper must not be dirty. If the back of the sticky ink is dirty, as long as the first time the ink map has met the requirements, the following consideration will be the second printing. When printing the second pass, first see if the color sample is the same as the appearance of the color mark. Once the color mark matches the appearance, it can be printed. The ink volume of the second pass must be smaller than the first pass, and it must be thin and cool, and thick, sticky flowers will affect the quality of the product.

How to detect the size of the second printing ink? You may wish to take a few sheets of white paper. The amount of ink is appropriate to cover paper patterns. It is also possible to balance the first pass of ink, so that you have a few hearts.
