Research on the Evaluation of Digital Prints Quality Based on Noise

With the development of digital printing, the needs for evaluating digital printing increase. In this study, the factors affecting the quality of digital prints are analyzed, and a set of digital prints noise detection system, test charts and evaluation methods are established by decoding the formation mechanism of the noise. Experiments showed that the noise had been affected by the type of paper, the image forming method of digital printing, the toner particles closely related in particular. As a result, this study can be used to select and optimize the printing’s outputting resolution to ensure printing quality based on subjective and objective evaluation the noise of digital printing.
