Difficulties in ink-jet fabrication are due to the versatile tunable resolution required, and, an ink-jet printing system with the architecture of multi printhead is usually used to expedite the processing time of production. It is complex arbitration for data format between the printing resolution and pattern data, especially for multi-heads platform architecture. In this architecture, we managed the printing data and kept their consistency between individual head modules, to avoid the lapses of printing data that causes defects, named “mura” at borders of printing regions near head modules intersections. This article proposed a memory arbitration mechanism for patterning fine images in multiple printhead system. The collective objective pattern data were allotted to each printhead depended on the input of physical dimension and rotation angle of printhead, and generated a parallelogram memory architecture at printing resolution to be printed and the system throughput can be raised to a much better one and the memory usage of the system will be very much efficiency.

  • 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.
