coefficient of friction by coating the paper-engaging surface with a ceramic
The surface of a platen against which paper is attracted by vacuum can be
provided with a constant coefficient of friction by the application of a ceramic
coating. The coating should be a hard, durable, non-organic material, such as
the preoxidized ceramics of aluminum or titanium oxide. Another material which
provides a similar surface is anodized aluminum which can optionally be
combined with other inert organic materials.
