A surface having tacky images which comprise toner-receptive and background areas can be color developed by applying to the toner-receptive areas a prolonged tack toner, heating the toned image to a temperature sufficient to make the toner tacky, reducing the temperature of the tackified toned image below the tackifying temperature, the toner remaining tacky, and repeating the toner application, heating and cooling steps at least once. The prolonged tack toned image can be used in single or multiple transfers to an image receptor. The transferred image can also be toned with prolonged tack toner to generate an image of higher optical density. |
