Using water-based plastic ink printing, first it does not need to use solvent, only water can.The printing industry often says how much solvent can be added.If you add 50% to 100% of the solvent in the ink, it is wrong to assume that the more solvent the better, the lower the cost.In fact, 50% to 100% of the solvent added is added to the entire printing process.This is due to the volatilization of the solvent caused by the change of ink viscosity.The faster the printing speed, the more volatile the diluent required to be deployed, the more times it will be added to the solvent.This is equal to increasing the cost of printing.So, not ten kilograms of ink has been added to five kilograms of solvent before it starts printing.The standard of ink industry, ink color concentration, low viscosity is good ink.Add thinner to ink, only as reducing ink viscosity.Make it suitable for printing, such as excessive addition, ink color concentration will decrease.The components of the connection are reduced at the same time, so that the product cannot be printed.So water-based ink only adds pure water, and is a one-time addition (before printing).In the printing process, it is not because of the change of viscosity and cause the color change, is not to like ink, for printing on the way to join the waste produced during the diluent, thus greatly improve the printing quality of the qualified rate.The cost of solvent has been saved and waste is reduced.This is one of the advantages of water-based plastic ink.
