    For ink, color, body bone and dryness are the three most important properties of ink, and it is also the most important thing to pay attention to when developing ink formulation and process and producing ink.
    1
    , resin
    connection material is a kind of gel-like fluid, its role is first as the carrier of pigments, powdered pigments and other solid particles mixed and linked together, and secondly, as an adhesive so that pigments can eventually be fixed on the surface of the bearing, in order to achieve the display text, images, decoration and other purposes. The resin in the connecting material can form a thin transparent film layer, which is why the ink can be filmed on the print

    . Therefore, the choice of resin solution will affect the final performance of the ink, such as drying speed, stability, gloss and so on.

    solvents
    in inks, solvents are used to dissolve resin-like film-forming substances and make solvent-based connecting materials. In plastic gravate inks, solvents not only dissolve various film-forming polymers, adjust viscosity and fluidity, but also have an important impact on film-forming quality, and also play a decisive role in the drying speed of inks. One of the key technologies in plastic graved ink formulations is to select the right solvent.

    , pigments
    printing inks used in colored materials are pigments, divided into inorganic pigments and organic pigments two categories, currently used in ink pigments are mostly organic pigments. In the production of printing inks, the pigment is dispersed in the connecting material, and then printed to the surface of the seal, so that the print presents a colorful image. Many properties of inks are related to pigments, such as their relative density, transparency, light resistance, heat resistance and resistance to chemicals. In a sense, pigments determine whether the finished ink can be suitable for a printing process or for the final use of the print.

    , additives
    additives are the auxiliary ingredients of ink, the main purpose of adding additives is to improve the stability of ink, printing performance, printing surface performance and so on. There are many kinds of additives, mainly plasticizers, desiccants, surfactants, dispersants and so on.
