How to determine the four-color offset printing color sequence?

Four-color offset sublimation printing ink is characterized by a wet-wet state transfer, all the color sequence alignment, first, take into account of the viscosity of the four-color ink relationship between each other. If the latter color ink viscosity greater than the previous one color, in the case of the surface of the drum may be the first against each other in the same color ink dot overlap is not printed, the former is often the same color ink flaking. This makes the printing ink can not be fully transferred to the first color of ink, but also to make the same color of ink before the ink is mixed in the same color, resulting in a mixing phenomenon, therefore, the same color of ink viscosity should generally slightly less than the pro-same color ink , it is not easy to produce color mixing phenomenon.

Secondly, the offset sublimation ink dry before infiltration condensate determine color sequence also need to consider fixing fast printing ink onto the paper, low-viscosity component and its link to feed a large number of solvent penetration into the paper momentary gap, leaving high viscosity ingredients and synthetic resin wrapped into a gel state fixed pigment in the paper surface. By fixing the ink penetrate the surface of the paper layer, which greatly increase the cohesion, so that if the viscosity of the ink is slightly larger than the second color ink of the first color mixing phenomenon does not occur, so that the printing conditions of infiltration with large transient four-color printing can be reduced the mixing phenomenon, for four-color printing color sequence arrangement is also provided for convenience.
