Abstract

945,372. Photographic colour printing. AGFA A. G. Sept. 1, 1960 [Sept. 3, 1959], No. 30234/60. Drawings to Specification. Heading G2C. In a process of printing from a colour image on to a multi-layer colour material, an additional uniform exposure is given prior to, during or after the imagewise exposure, the additional exposure being to light of a colour temperature to which the printing material is balanced and amounting to 10 to 20% of the imagewise exposure. The imagewise exposure is through a filter or filters selected in accordance with the colour balance of the original image and of the printing material.
