Abstract

A multiple rotation drum architecture for printing color or black on plain paper is disclosed. Some problems encountered with color thermal ink jet printing on plain paper include: inks running together and mixing on paper causing rough edges, feathering, color fidelity and color saturation problems; and high ink fluid coverage (150%) causing mechanical distortion of paper called cockle and curl. Cockle and curl that occurs during printing may be as large as 0.20 inches causing paper to hit printheads typically 0.02 to 0.04 inches from the paper and reducing image quality.
