| Zusammenfassung: | Highlight color imaging apparatus wherein tri-level images are created by using a transparency with optical densities suitable for forming a bi-level image having relatively high and intermediate voltage levels. A modulated light source is then employed to form a third voltage level on the imaging surface by reducing the intermediate voltage level to a relatively low residual voltage level. |
