Abstract

See full text

The present invention provides a dynamic adjustment of the printed fluid volume for underprinting and/or overprinting pigment-based inks (or other inks) for speeding up the drying time of the pigment-based ink or improving its adherence to a medium. The invention identifies a characteristic in the printer that affects the optimum volume of under/overprinted fluid to be printed, such as pen temperature, operating frequency, operating life, ambient temperature, and ambient humidity, and varies the printed volume of the under/overprinted fluid accordingly.
