Both of the theoretical and experimental analysis of the halftone image are reviewed in this paper. An approach is shown for evaluating the reflected light intensity from the surface printed solidly on which both of the macroscopic and microscopic fluctuations in ink thickness exist. The statistical nature propagating from microscopic fluctuation on dots to the average reflected intensity is also measured with the various analyzing techniques and equipments. The image processing systems composed of microprocessor have been effectively used for analyzing printed dots and press systems. This suggests that the micro-processor will be able to control the printing press by getting the information as an image if an analytical or statistical solution about the relations between perturbations in the printing process and the disturbance in printed results can be found out successfully.
