ABSTRACT:
Multicolor printing on a high speed web-fed press with cold-set ink increases production efficiency over that of a press with dryers. For this purpose, newsprint is used because of its good oil absorptiveness, however, the printing quality is not satisfactory. A coating including needle form pigments, the average oil absorptiveness of which is more than 65 cc/100 g, was applied on the base paper, and coated paper for the high speed press was produced. The present invention increases the reproducibility of dots and sharpness of print patterns compared comparing to usual newsprint without decreasing the handling efficiencies
