ABSTRACT:
A method and apparatus for controlling curl in a liquid ink printer. The liquid ink printer deposits an anticurl material on the side of a printed sheet opposite the one having printing deposited thereon. The anticurl material is a fluid which counteracts the steady state curl in the direction of the printed image resulting from active drying of the printed sheet. The back side of a printed sheet has deposited thereon an anticurl fluid which can contain water, a penetrant, and a humectant like material such as diethylene glycol, ethylene glycol, sulfolane and glycerin. The anticurl material is deposited with a roller made of a foam material for absorbing the anticurl fluid or a roller having dimples disposed on the surface thereof. In addition, the anticurl fluid can be deposited by a spray device or a thermal ink jet printhead ejecting anticurl fluid.
