Abstract
A process and apparatus are presented for making in-situ an energy sensitive surface on a passive support medium from at least two materials which in combination render said surface energy sensitive, comprising means for forming a separate mist of each of said materials and causing said separate mist to simultaneously contact said support media so that said materials controllably mix as they strike said medium. The particular process is utilized in a printing, copying and or recording environment wherein, said energy sensitive surface is formed on-line immediately prior to exposing said surface to an energy source. Said mists may be mixed at the point of contact with said medium or premixed within said mist forming means prior to striking said support medium.
Claims16
A non-impact recording process including the forming of an energy sensitive surface on a support medium in real time with respect to said recording operation, from a plurality of materials which will produce a visible mark on said surface in response to the impingement of an external energy sources thereon, said process comprising:
- forming at least two solutions from said materials with suitable solvents,
- forming said solutions into a finely divided mist,
- directing said mist onto the surface of said support medium with sufficient velocity to wet same and to form a composite uniform coating thereon, and
- selectively exposing said coating to said external energy source to form visible images thereon immediately after forming said coating.
A non-impact printing system including a paper support medium which is substantially non-sensitive to the impingement of an external energy source thereon,
- means for continuously passing said support medium past a recording station,
- means included in said recording station for forming a mist from at least two separate solutions which when mixed form a composite material which will form a visible image when exposed to a suitable external source, and
- means for causing said mist to be directed onto the surface of and form a uniform coating on said surface,
- means for applying an external energy source to said surface in selected areas where it is desired to make a visible mark immediately subsequent to said coating operation, and
- means for continuing said coating and recording process to form desired images on said surface.
