The simulation of print quality (PQ) defects is a process in which an image is degraded by artificially generated structures to create an impression of real defects when the image is viewed or printed. The simulation algorithms generate a set of defective images that can be used in diagnostic tools for printer users. These algorithms can also provide experimental images for psychophysical evaluations regarding defect perception, which requires the capability to control the level of the defects. In addition, simulation of defects aids in testing the usability of a PQ assessment page, and the development of computer algorithms for detecting PQ defects. Thus there are many applications that need high quality simulation of PQ defects. However, little research has been devoted to this work. In this paper, we characterize the common PQ defects in color laser printers such as banding, streaks, ghosting, and repetitive artifacts. We classify these defects into three categories: defects of uniformity, defects of random marks or repetitive artifacts, and color defects. We develop a simulation model for each defect based on its features such as the shape and the spatial distribution of the defect marks, or the tone dependency of the defect. The defects are simulated on RGB color continuous-tone images.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
