Abstract:
1. An apparatus comprising: an ink tuning system implemented in a printing system, wherein the printing system includes a production printer that is operable to print color ink onto a continuous-form medium, and includes a radiant dryer that is operable to dry the ink that is applied to the medium by the production printer; the ink tuning system is configured to identify areas of Key (K) black ink designated for printing on the medium by the production printer, and to apply a liquid agent to the areas of K black ink to increase the liquid mass of the K black ink before the medium enters the radiant dryer so that a mixture of the K black ink and the liquid agent dries at a lower rate; the ink tuning system is further configured to adjust the amount of liquid agent to apply based on a power level being used within the radiant dryer.
