Digital printing onto polyester sheet for producing durable catalogues and manuals economically - uses high transfer potential and sparingly conductive surface producing books only half as thick as paper equivalent, printed on both sides and highly resistant to solvents, climate and wear

摘要

A digital printing method imprints a special durable substrate (5). Individual ink or toner components are applied by electrical transfer potentials in immediately-consecutive printing zones. Novel features include use of a polyester sheet with an electrically-conductive outer layer. Also the transfer potential is set sufficiently high, to effect adequate adhesion of the applied ink components, in relation to the transfer potential effective in the following printing zone.
