HP Indigo press with liquid toners is marketed as a digital press with offset print quality. This study was to compare the print quality of HP Indigo 3500 to Heidelberg Speedmaster CD74. The parameters studied were color gamut, mottle, line resolution, dot quality, and tone reproduction. Printing was done on gloss coated paper with each press. The parameters were used to compare the quality quantitatively. The results showed that HP Indigo 3500 press produced decent print quality. The line and dot resolution of such press were not as competitive as those of conventional CTP offset lithographic printing. Due to the different colorants used in the printing processes, the color gamut produced by HP Indigo 3500 was smaller than the one produced by offset lithographic printing when four process colors were used.

  • 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.
