you''re using a dry pigment as a base, you''ll need to use more binder (usually 1 teaspoon per 2ounce [60 ml] bottle). If you plan to use your ink for a pen, try to limit yourself to just a few drops of gum arabic for each small bottle. Add a few drops of wintergreen oil, or a whole clove, to each bottle to keep the ink from moulding. 5

Ink chemistry. Milling is carried out in two stages the primary mixing is done with an ordinary mixer and the resultant pre mix is subjected to secondary grinding in a ball mill or a roller mill After the primary mixing the chemist adds chemicals called dispersants or grinding aids to prevent the fine pigment particles from reaggregating during the grinding stage The correct

（ink）Dispersion and Grinding Solution for Ink Industry. There are many pigments in the ink whose basic particle size is very small. However, due to the adhesion of these basic particles, they aggregate into large aggregates. Groups, at this time, a sand mill is needed to disperse and grind to the degree required by the material.

The invention is pigment grinding aids for waterbased inks which are produced by reacting an unsaturated fatty acid and/or resin acid with either acrylic acid, metacrylic acid, fumaric acid, or maleic anhydride to form a polycarboxylic acid anhydride. The polycarboxylic acid anhydride is reacted with an excess of polyamine to produce an amidoamide or imidoamide intermediate.

making is a dirty, toxic process which I think is mostly done offshore now, in places with more lax environmental laws than North America. Ink is made up of 3 parts: pigment, vehicle, and additives. The vehicle is composed of resin dissolved in a solvent. The pigment is mixed, or "ground", into the vehicle.

The basic formulation of ink involves the grinding of pigment in a vehicle to form the pigment dispersion, then letting down the pigment dispersion with suitable resins to meet rheological and functional properties. The main components of waterbased inks are pigment, binding agent, carrier (water) and additives. Binding agents are acrylic resins, which are emulsions or diluted
