A new ink jet printhead of the push mode type has been developed for use with solid ink and applied to a direct plate-making printer, Model SJ02A, for the offset press. Stack piezoelectric transducers (PZT), that displace in the direction of polarization, permit jetting of solid ink at frequencies in excess of 20 kHz. Standard dot density is 600 dpi. Drop size is modulated, by driving the transducers in a multi-pulse mode. A press plate is constructed by jetting hydrophobic solid ink from the printhead onto the hydrophilic plate. The plate is used directly on the offset press. Advantages of this printing system are the elimination of the developing process, and allowing use of various plate materials, such as, paper based plate, film plate, and aluminum based plate. The printhead can also be used to successfully jet liquid ink of viscosity in the range 5 - 20 cP, and thus can be applied to industrial printers in general.

More about this publication?
  • 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.
