Ink-jet printer for printing on cards

摘要

An ink-jet printer for printing on cards includes a printing station having an ink-jet printhead. A reservoir containing an ink is coupled to the ink-jet printhead. The ink includes: a medium consisting of a low-boiling organic solvent, an auxiliary solvent consisting of a high-boiling organic solvent, and a coloring component soluble in said medium. A driving system is adapted to drive the printhead between a first operative condition wherein the ink ejected by the printhead impinges on the card, and at least a second operative condition, wherein the ink ejected by the printhead does not impinge on the card. A control unit is active on the printhead for commanding ejections thereof, and on the driving system for controlling movement of the printhead. The control unit is configured for commanding an ink ejection in the second operative condition before ink ejection in the first operative condition.
