Each new printing product needs to have an increase in performance over previous products. As customers continue to demand higher speed printers with higher resolutions, printheads need to have higher jetting frequencies, higher jet densities/number of jets and smaller drop masses to meet these demands. These performance increases have created an issue called dot position amplification. Dot position amplification is the increase in color-to-color misregistration when a secondary color is deposited. This issue is caused from an increased delay time between the deposition of secondary pairs of drops to the same location and a decrease in time for solidification because of drop size reduction. This increase in delay time and decrease in solidification time is enough for the first drop to freeze before the second drop is deposited. The second drop appears to fall to one side and increase the color-to-color dot position error. This paper presents a method to mitigate this amplification by intentionally misregistering the colors.

  • 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.
