One has undertaken a number of spot color printing products in the field, using 80g/m2 coated paper. According to the conventional practice, we should print a PS printing on the field, but we used the old PS plate to print good quality, full field printing products without any flowers, which was well received by customers. The specific approach is to use an old PS version that is flat and smooth without any lens bumps and breakages. When printing, the reverse side of the plate faces the front, faces up, does not reach the water, and is only inked.
When printing coated paper, it is best to use quick-drying ink in order to prevent the back surface from being dirty. The 8% viscose is very effective for preventing stickiness. The addition of a tackifier to the ink not only prevents tackiness, but also does not affect the color saturation, and the ink layer appears brighter, clearer and more convenient for postpress processing such as calendering, laminating, bronzing, and the like.
Here, the viscose can replace dry oil and other anti-sticking dirty materials.
