Abstract

Investigation of the tradeoffs between the number of quantization levels and spatial addressability of printed color images was performed. Error diffusion in CMYK color space was used to quantize the images. Quantized images were printed on a single color printer simulating different spatial addressabilities. A psychophysical experiment was conducted to evaluate the perceived image quality (IQ) of the prints. The conclusions on the tradeoffs were drawn based on the results of the consequent statistical analysis. It was determined that the tradeoffs were scene dependent with pictorial scenes being able to sustain greater reduction in addressability without perceived IQ being decreased than graphics. The results of the experiment demonstrated that pictorial scenes were sufficient to be printed with 5 bits per color (bpc) per pixel at 100 dots per inch (dpi), and graphics -- 3 bits per color per pixel at 300 dpi in order to match the perceived IQ of the best possible, 8 bpc - 300 dpi, combination for the given system at normal viewing distance. If a single bpc-dpi combination was to be named as the optimum, it would have to be 3 bpc - 300 dpi.
