  • Abstract:
    Impregnated, prepared, vellum or oiled papers are different names for this type of tracing paper that was produced by coating the paper with a varnish in order to make it translucent.
    Most commonly used oils have inherent oxidizing features, making the paper brittle and acidic after time. Fragility may be such that dissuade against any manipulation, since a regular handling might involve tears. The varnish also prevents cellulose from moisturising normally and its conservation is therefore quite complex. A replacement of the varnish intends to stop oxidation and enable wet treatments in order to improve the paper condition as well as maintain its transparency.

(I must correct myself in the misuse of the word “rows”, which meant to say “columns”, at the very last slide, from the minute 54′ on… my appologies for the confusion!)
