Disclosed in a process for producing gloss and smoothness on the surface of a paper web, comprising: A. advancing a web of papermaking fibers through a nip formed by a smooth metal finishing drum and a resilient backing roll; and B. heating the drum to a temperature at least high enough to heat a substrata portion of the web to a temperature in which gloss and smoothness rapidly increase with increasing temperature due to thermoplastic molding of the substrata beneath the surface and at a temperature higher than where substantial gloss and smoothness would have already been obtained by molding of the surface of the web.
