Variable data clear mark imaging |
| abstract |
A security document is produced from a paper substrate having invisible hydrophobic toner blended into the paper. The clear toner is produced by milling (11) and classifying (12) a polyester resin, mixing it with a silica flowing agent (13), and then electrostatically imaging the toner (16) onto the paper substrate. An infrared absorbing a UV responsi ve dye may be added to the toner so that it is visible under infrared/ultraviolet light respectively. When applied to the paper the toner is snow white, but after infrared heat fusing (18) it blends into the paper and is substantially invisible. The security indicia is easily mad e visible by passing a conventional marker nib over it, or other mechanism for applying a water based low concentrate colored ink (20) which is readily absorbed by the surrounding paper, but not by the hydrophobic security indicia. |
