Abstract

The advantage of using a single screen-angle (Dot-on-Dot) reproduction for multicolor halftone printing is a sharper reproduction with the decrease, of. a rosette pattern in all image areas. The purpose of this study was to quantify the differences of color image quality between conventional reproduction using four screen-angles and a single screen-angle printing technique. In addition, the influence of screen frequency to the final color image quality in the Dot-on-Dot printing was also investigated. The results of this study confirmed that there is a linearity of image quality for all color halftone printing regardless of the arrangement of the screen angle. Test results also indicated that Dot-on-Dot was preferable to the conventional four screenangle technique at the low screen frequency. Under different reproduction circumstances, input image quality and reproduction screen frequency have different weight toward determining the quality of the final reproduction.
