Phototypesetter previewer initial specification

The current situation at Wollongong University regarding the phototypesetting of documents has two main inadequacies. Firstly the average time between the submission of a job and the receipt of a finished document is probably greater than a week. This is an unacceptably long time if one or more error correcting stages is required before an accurate document is produced. Secondly the cost of phototypesetting is high currently sixty cents per (A4) page. The correction of errors can therefore be expensive as well as time consuming. A solution to these problems would be an easy method for accurately previewing output before it is submitted for setting. The graphics facilities required for such a previewer are provided by the I.C.L. Perq computer. This document gives the specifications of a phototypesetter previewer designed to run on the Perq.
