Abstract
A method for printing with a plurality of dies. A plurality of dies is provided, with each die having a plurality of drop generators that are configured to eject drops of a same colored fluid. The drops from each die have a corresponding nominal drop weight at a reference temperature of the die. At least one of the dies is warmed to a corresponding elevated temperature higher than the reference temperature in order to substantially equalize the nominal drop weights of all of the dies.
