Paper Abstract

This paper investigates the feeding of receiver (recording paper) by capstan roller for thermal transfer type color printing. In thermal transfer color printing systems, this kind of feeding mechanism including a motor driven capstan roller and a pinch roller is commonly employed. It repeatedly advances receiver back and forth to overlay different color image separations. Since this mechanism handles the receiver by friction, accurate receiver feed registration without slippage is important factor for high printing quality. The surface characteristic of capstan roller can influence the receiver feed precision and the color registration. So the experimental apparatus with different kinds of capstan surface is established to examine this effect upon receiver feed registration. It can find the method of avoiding mis- registration. The results presented will be very helpful for mechanism designers to make better choice in developing this kind of receiver feed mechanism.
