ABSTRACT:
A device for increasing the image density of laser prints includes a machine, a rolling mechanism and a driving mechanism; wherein the machine is disposed with a paper inlet and a paper outlet; the rolling mechanism and the driving mechanism are disposed inside the machine; a processing tank for darkening the toner is disposed at the lower aspect of the rolling mechanism inside the machine; some solvent of the prior art is placed inside the processing tank for darkening the toner; a sheet of tracing paper is fed into the area of the paper inlet; the toner darkening solvent contacts the paper and darkens image areas covered by the toner along the rolling of the lower rolling shaft. Then, the darkened tracing paper is sent out from the paper outlet, after drying, which works directly as a film for exposing the plate during plate making in order for printing.
