An apparatus and method for measuring the drying rate of a liquid or liquid film in air or other gaseous media by either: a) measuring changes in the print density of the liquid; b) measuring changes in the dynamic surface tension of the liquid; c) measuring the differential pressure between an inert gas required to displace a sample of the liquid drawn into a capillary tube from a reservoir of the liquid and the pressure required for a bubble of the gas to form in the reservoir; and d) measuring the electrical conductance or resistance of the liquid.

Apparatus and method for quantitatively measuring liquid film drying rates on substrates

A flexographic preprint ink composition, which includes at least 3 weight percent of a pigment; at least 15 weight percent of a hydrolyzed gelatin; and water. The ink composition may also contain conventional additives, such as surfactants and defoaming agents, typically found in flexographic ink compositions. The flexographic ink composition can exhibit better heat resistance, mileage, strength, wet trap, foam resistance, drying, stability, and plate transfer than conventional flexographic inks which contain soy as a binder.

Flexographic ink composition containing hydrolyzed gelatin as a binder resin

A printing ink composition containing resin and glycerine, wherein the composition has less than 5 wt. % volatile organic compounds and has no hazardous air pollutants and a method of preparing such composition.
