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 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.

    Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
