Abstract
PURPOSE:To correctly reproduce chromaticity and gradation by selecting light wavelengths which require the same energy in a period from start of coloring of each coloring material on the surface of a photosensitive recording sheet to its completion, and simultaneously projecting the light beams of said wavelengths from a color CRT. CONSTITUTION:For wavelengths transmitting each colors separation filter 37, 39 and 41, in case of yellow (Y), it is 475nm, slightly longer than before, and in case of cyan (C), it is 625nm, slightly shorter than before. Since the brightness changing rate of CRTs is the same when artificial energy increases to accelerate coloring, the same amount of energy increases, and magenta, yellow and cyan wavelengths complete coloring at the same time. Namely, such wavelengths are selected that require the same amount of energy from the start of coloring to its end, and exposure is performed by those wavelengths: therefore three types of coloring rates complying with three types of energy rates of a light source can be attained.
