The MTF of Printing Systems
Abstract:Many imaging systems are described by an MTF function. However, MTF is defined rigorously only for linear imaging systems, and the printing process is intrinsically non-linear. However, a spatial attenuation function we call the Printer Transfer Function, PTF, can be defined experimentally, and it behaves much like an MTF. The measurement of the PTF is illustrated for a 300 dpi electrophotographic printer. The PTF is shown to be experimentally independent of the halftone pattern printed, but a scaling factor, r, which is highly dependent on the halftone pattern, is required in order to calculate the noise power spectrum, NPS, of the printed halftone from the NPS of the ideal halftone in the computer.

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.
