On making graphic arts quality output by computer
Computer Laboratory, University of Cambridge, Corn Exchange Street, Cambridge, UK
The design and production of high quality page images falls within the competence of the printing/publishing profession and tends to be regarded as specialised and difficult by those outside it. Modern developments in computer driven output devices, (COM machines, film setters and precision plotters) makes available the facilities for production of such images much more widely and it seems inevitable that they will influence greatly, if not determine, the future of printing. There is, however, much to learn. Printing is a craft industry with variable, but often highly aesthetic, technical standards which are difficult to measure and dispense to newcomers. The use of new technology may relieve the craft of some previous limitations, but may also impose new ones for which different standards have to be devised.
This paper presents some of the basic techniques which are being developed for the use of the Laser Scan HRD-1 display plotter in the production of high quality images and some of the problems encountered which are connected with the subjective assessment of such images.
