摘要：
A transfer sheet for thermal reproduction processes having a discontinuous transfer layer defined by a plurality of closely spaced discrete carbon regions. In a specific embodiment the transfer surface is defined by a substantially uniform distribution of carbon regions of varying diameters providing improved continuous tone reproduction through temperature-correlated carbon transfer.
