Abstract
A printing machine including a printing plate on a surface of a rotating cylinder, in which the printing plate has a fixed pattern for receiving a toner; a vessel containing the toner, which includes a pigment and a thermoplastic binder, in which the fixed pattern is a permanent pattern in a form of selected portions of an image is disclosed. A plate for use in the printing machine is also disclosed. A printing system is also disclosed.
Claims20
A printing machine comprising:
- a printing plate on a surface of a rotating cylinder, wherein the printing plate has a fixed pattern for receiving a toner;
- a vessel containing the toner, which includes a pigment and a thermoplastic binder,
- wherein the fixed pattern is a permanent pattern in a form of selected portions of an image;
- and
- wherein the printing plate comprises:
- a relatively positively charged layer of non-conductive material;
- a relatively negative charged layer of non-conductive material having gaps therein;
- and
- a layer of electrostatic material positioned between, and interfacing with, the relatively positively charged layer of non-conductive material and the relatively negative charged layer of non-conductive material, the relatively negative, charged layer of non-conductive material forming a fixed pattern along a surface of the electrostatic material, the fixed pattern including two or more areas that have a different electric charge.
A printing plate for use in an electrostatic printing machine comprising:
- a relatively positively charged layer of non-conductive material;
- a relatively negative charged layer of non-conductive material having gaps therein;
- and
- a layer of electrostatic material positioned between, and interfacing with, the relatively positively charged layer of non-conductive material and the relatively negative charged layer of non-conductive material, the relatively negative, charged layer of non-conductive material forming a fixed pattern along a surface of the electrostatic material, the fixed pattern including two or more areas that have a different electric charge;
- wherein at least one area has an electric charge that repels toner;
- and
- wherein at least one area has an electric charge that attracts toner.
A printing system, comprising:
- two or more printing machines, arranged serially, wherein each printing machine includes a printing plate having a fixed pattern in a form of a select portion of an image;
- and
- two or more fusing units, arranged after each printing machine;
- wherein each printing machine prints a select portion of the image, and each fusing unit fuses the printed selected portion of the image,
- wherein the printing plate comprises:
- a relatively positively charged layer of non-conductive material;
- a relatively negative charged layer of non-conductive material having gaps therein;
- and
- a layer of electrostatic material positioned between, and interfacing with, the relatively positively charged layer of non-conductive material and the relatively negative charged layer of non-conductive material, the relatively negative, charged layer of non-conductive material forming a fixed pattern along a surface of the electrostatic material, the fixed pattern including two or more areas that have a different electric charge.
