What is the effect of solvent on the ink resin to hold?

System resin hold degrees of solvent is not only explains the concerning the compatibility of resin and solvent ink system, is also the root cause of the ink system has a good flow property. If ink system resin to hold degrees of solvent is too low, will have the ink system resin precipitation phenomenon, ink will be returned to the thick, poor flowing property, serious impact on the adaptability of printing. Resin to hold degrees of solvent is too high also to have the downside, it also brings a problem, because the ink formula used in the solvent system of resin dissolved force is too strong, after printing ink film should be volatile organic solvents is not easy to escape from the film-forming resin, ink membrane drying speed significantly slower, solvent residue increase, printing quality after winding, residual solvent will permeate, diffusion to produce printing quality back glue phenomenon!
