Abstract
A functional color graphic printer wherein Traveling Cloud Development (T.C.D.) is utilized for developing Ionographically formed color images. The high sensitivity and scavengeless character of the T.C.D. process enables the use of a low voltage imaging system such as ion deposition processes such as CorJet or IBIS or IBIS II to form three or more latent images simultaneously or sequentially on a single dielectric receiver. The charge levels of the elements of the latent images may been varied in order to produce different color intensities for each component of a composite image. Alternatively, the different color intensities can be achieved by changing the electrical biases applied to the traveling cloud developer systems.
Claims6
A method of printing color images using relatively low image potentials, said method including the steps of:
- using ionographic imaging structure, forming a relatively low voltage, latent image on an image receiver, said relatively low voltage being about 350 volts;
- passing said latent electrostatic image past means for developing said latent electrostatic image with toner;
- and
- electrically biasing said developing means for establishing a relatively low, net image potential of about 50 volts between said developing means and said latent image for effecting toner deposition on said latent image from said developing means.
