INTRODUCTION
The present note describes problems occurring during the
production of a small number of photoetched stainless steel
plaques for the Golden Jubilee of the Kodak Ltd. Research
Laboratories at Harrow. Problems arose both beacause the
plaques were designed to be inspected with a x 5 hand
magnifier and from limitations of available equipment for
mass production. Nevertheless, the solutions adopted could
be of help to others facing similar circumstances. The problems
can be classified under three headings:
Control of line width and dust shadows.
Combination printing with acceptable register at the final
image size.
Minimizing blemishes arising from metal etching characteristics
