Treatment of preprinted media for improved toner adhesion
The present invention relates to surface treatment of printed media, and more particularly to surface treating media for improved toner adhesion, wherein the surface treatment includes corona discharge, plasma treatment, ozone treatment, UV treatment, electron-beam treatment and electron beam radiation, and the media is preprinted.
1 . A method of printing comprising the steps of:
marking the surface of a media with a first marking material;
treating the surface of the media to increase the surface energy thereof; and,
marking the surface of the media with a second marking material after treating.
2 . The method of claim 1 , wherein treating comprises corona discharge treatment.
3 . The method of claim 1 , wherein printing comprises electrostatographic printing.
4 . The method of claim 1 , wherein treating comprises plasma treatment.
5 . The method of claim 1 , wherein treating comprises ozone treatment
6 . The method of claim 1 , wherein treating comprises UV treatment.
7 . The method of claim 1 , wherein treating comprises electron-beam treatment.
8 . The method of claim 1 , wherein treating comprises electron beam radiation treatment.
9 . The method of claim 1 , wherein the first marking material is ink and the second marking material is toner.
10 . The method of claim 1 , wherein the second marking material is comprised of toner.
11 . The method of claim 1 , wherein treating comprises heat treatment.
12 . The method of claim 1 , wherein treating comprises heating the media while treating.
13 . The method of claim 1 , wherein the media is heavy media.
14 . The method of claim 1 , wherein treating comprises driving off the volatiles from the media.
15 . A print apparatus comprising:
a printer to mark the surface of a media with a first marking material;

25 . A print apparatus according to claim 15 , wherein treating comprises heat treatment.
26 . A print apparatus according to claim 15 , wherein treating comprises heating the media while treating.
27 . A print apparatus according to claim 15 , wherein the media is heavy media.
28 . A print apparatus according to claim 15 , wherein treating comprises driving off the volatiles from the media.
29 . A method of printing comprising the steps of:
marking the surface of a media with a first marking material;
treating the surface of the media to increase the surface energy thereof; and
marking the surface of the media with toner in an electrographic print engine after treating.
30 . A print apparatus for printing on media comprising:
a printer to mark the surface of a media with a first marking material;
a surface treatment device to treat the surface of the media to increase the surface energy thereof; and
an electrographic print engine to provide toner on the surface of a media with a second marking material after treating.
