Title:
DIRECT ELECTROSTATIC PRINTING METHOD AND APPARATUS WITH INCREASED PRINT SPEED
Document Type and Number:
WIPO Patent Application WO1999043502
Kind Code:
A3
Abstract:
An image printing device and method for printing an image to an information carrier. The image printing device includes apertures which can be selectively opened or closed to permit or restrict the transport of pigment particles during print sequences, a predetermined number of which print sequences are included in a print cycle, to thereby enable the formation of a pigment image. Further, deflection electrodes are included for, by means of predetermined deflection voltages related to each one of the predetermined number of print sequences, controlling the deflection of pigment particles in transport to thereby be able to deflect pigment particles against predetermined locations in view of the image which is to be printed. To enable a faster print speed, according to the invention, the change of the predetermined deflection voltages of a previous print sequence to the predetermined deflection voltages of a current print sequence is time displaced relative to the beginning of the current print sequence.
