KENNEY then discussed several samples of the quality achieved in the project that had been distributed in a handout, for example, a copy of a print-on-demand version of the 1911 Reed lecture on the steam turbine, which contains halftones, line drawings, and illustrations embedded in text; the first four loose pages in the volume compared the capture capabilities of scanning to photocopy for a standard test target, the IEEE standard 167A 1987 test chart.

This standard is used with the IEEE fax image--a continuous tone photographic image with gray scales, text, and several continuous tone pictures--and AIIM test target number 2, a representative document used in office document management.

More specifically, a shortcoming of algorithms which are well behaved when run on gentle floating point hardware (such as IEEE-standard or PDP-series machines) but which break down badly when exposed to a Cray's unique `rounding' rules.
