Share: how to influence the ink color print quality

Perhaps in the eyes of ordinary people, monochrome printing and color printing samples sample compared to a lot of simple process, the ink requirements will be relatively low. In practical operation, the printing staff has pointed out, monochrome printing sample requirements are not low on ink, ink modulation great quality monochrome printing samples for impact. Due to the stronger polar ink-soaked, it will promote the emulsification of the produce, the ink viscosity will increase its cohesion, is the viscosity of the ink so that the adhesive force between molecules strengthened. Therefore, when monochrome printing samples, to strengthen the capacity to make it water resistant, and viscosity of the ink in the printing process must be adjusted in order to achieve an appropriate printability, which affects ink emulsification. Professionals will be in the deployment of the ink, adding an appropriate amount of control, general varnish not only dilute ink, but also the flow of ink increases, the viscosity decreases, the cohesive force between molecules weaken, affecting the ability to engage in water ink can cause emulsification production. From the nature of the pigments in the ink, the different colors of ink, which uses pieces of quality pigments differ, determine the difference between the value of its emulsification. Such as: a pigment ink made of carbon ink, emulsifying value is small, easy to emulsify, mainly water-repellent carbon black with good reason. Lake pigment ink made of, since the extender pigment is aluminum hydroxide, aluminum, barium white pigments such as hydrophilic, the ink structure can easily be damaged during the printing process, the pigment particles can act as an emulsifier, resulting in ink emulsified.
