Method and apparatus for transferring a principal substance and printing system

摘要

A method and apparatus for transferring a principal substance applies the principal substance onto a surface and deposits drops of a gating agent onto a first portion of the principal substance applied to the first surface. The depositing of each drop of gating agent is individually controlled. A second portion of the principal substance not covered by the gating agent is transferred from the first surface to a second surface. A printing system adapted to transfer principal substance from a first surface to a second surface is also disclosed, wherein the printing system exerts mechanical pressure between the first surface and the second surface.

主权项

1. An apparatus for transferring a principal substance, comprising:
a gating agent; a principal substance; a surface; an application apparatus for applying the principal substance to the surface; a depositing apparatus for depositing the gating agent on top of the principal substance wherein at least one portion of the principal substance is not covered by the gating agent; and a means for transferring distinct from the depositing apparatus for causing both (a) the gating agent covering the principal substance and (b) the at least one portion of the principal substance not covered by the gating agent to contact a print medium whereby, with respect to the principal substance, substantially only the at least one portion of the principal substance not covered by the gating agent is transferred to the print medium, wherein the means for transferring causes the transfer of the at least one portion of the principal substance not covered by the gating agent without applying a charge.
