A method for writing an imageable material using multiple beams includes preparing subsequent patterns each having Y rows of N pixel locations, said subsequent patterns including first and second patterns; where the first and the second pattern overlap with each other in an overlap area consisting of O columns and Y rows of pixel locations; selecting for each row i of said first pattern Mi1 pixel locations; selecting for each row i of said second pattern Mi2 pixel locations; writing simultaneously, for each row i, said Mi1 selected pixel locations by moving the N beams in a fast scan direction relative to said imageable material; and moving said N beams relative to said imageable material in a slow scan direction over (N−O) pixel locations; writing simultaneously, for each row i, said Mi2 selected pixel locations by moving the N beams in a fast scan direction relative to said imageable material.

A compliant surface is created with micron scale dimples above an electrically biased conductive layer. The dimpled surface is charged to a desired charge density and filled partially with fountain solution in either order. Then the compliant surface is brought adjacent a charge-retentive surface bearing an electrostatic charged pattern. In examples the fountain solution charge is repelled in the downward directed field under discharged (or uncharged) regions of the charge-retentive surface and is attracted to the surface at the electrostatic charged pattern in the regions of charged pixels. Electrostatic forces drag the fountain solution from the dimples to the charged pixel surface and away from the discharged pixel regions. Electrophoretic forces cause the fountain solution within the dimples to flow up to the charge image and wet the surface. A desired volume is controlled by varying parameters such as nip pressure.
