Page width Ink Jet printing is powerful printer for fast printing speed and low printing cost. But page width printer consists of multiple head chips array across the printing media, the chip to chip variation of jetting performance causes to banding image. In this study, evaluation of individual ink Jet Head chip is performed, and the result is correlated to printed image quality by array type ink jet head especially in bending. Drop volume and trajectory error of ejected ink drop are measured and analyzed. The enhancement technology is presented to compensate for image variation across the printing media.
