<p>PCT No. PCT/NL90/00136 Sec. 371 Date Mar. 12, 1993 Sec. 102(e) Date Mar. 12, 1993 PCT Filed Sep. 19, 1990 PCT Pub. No. WO92/05477 PCT Pub. Date Apr. 2, 1992.A method for providing an image on either opaque or transparent substrates (42) to have substantially equal apparent color saturation when viewed and including the steps of: developing a latent electrostatic image on an image bearing surface (16) using a colored liquid developer in a developer system operating at given voltages; and subsequently transferring the image to the substrate (42) wherein said liquid developer, developer system and voltages are the same for printing on both opaque and transparent substrates. The method utilizes a control apparatus, operative when the substrate (42) sought to be printed is transparent, for causing each toner image to be developed on an image bearing surface (16) and transferred to an intermediate transfer member (40) a plurality of times, before the image is transferred therefrom to the transparency, and when the substrate (42) sought to be printed in opaque, for causing each toner image to be developed on the image bearing surface (16) and transferred to the intermediate transfer member (40) only once, before the image is transferred therefrom to the opaque substrate.</p> |
