A Novel Approach to Print Head Alignment for Wide Format Printers

For applications using multiple print heads, print head alignment is often achieved through a laborious iterative process of print testing and adjustment.

In order to streamline this process, we have enabled an off-line pre-print alignment method. Relying on quantitative analysis rather than educated guesswork, this procedure enables quick and reliable alignment of the print head in the assembly.

This method uses a precision fixture to hold the print head, while a semi-automated image capture and analysis package provides immediate feedback to the alignment technician as to the direction and magnitude of the necessary alignment changes.

The technique described in this paper has benefits both in the manufacturing environment and in field support.

This paper will discuss the details comprising this novel alignment process including the interaction between the user and the system.

  • 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.
