Printer Simulation Model
In developing a new printer, it would be convenient to have a method to predict what the image quality of this printer will be, before one has actually built it. One method is to try and estimate the image quality parameters (like graininess, line sharpness, bleeding etc) from the design parameters like drop size, placement accuracy, interlacing, ink behavior etc.
However the traditional image quality parameters produce a series of numbers which are not easily interpreted, making it difficult to determine which printer design parameters are too tight or too wide.
Therefore we tried to simulate the output of the printer with different design parameters to get an idea of the print quality of the printer which is understandable for everyone.
To produce this simulation, an image is put through the normal color management, dithering and interlacing scheme, and for each drop of ink, the position of this drop (including all positioning errors), its size and intensity is stored. This information of drop positions and properties is fed to a raster image processor, to create an image at a higher resolution than the printer we try to simulate. This high-resolution image can than be printed on either a high-resolution printer for normal viewing, or enlarged for viewing from a larger distance.

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.
