How "Exposure Head" print digital data on the plate?
i read in the basysprint operator manual that
"The light source of the exposure head is made light modules. Each module contains a laser diode that generates violet light. The laser-light from each module is collected in the light collector and sent through the optical fibers to the light compensator. The compensator bundles the energy and directs it towards the heart of the exposure head: the DMD™ or Digital Micromirror Device™. During exposure, the light modules send violet light to the DMD™. The result will be a mini-picture on the plate, the size of the DMD™. If the exposure head moves, an entire rastered image can be created on the plate".
My question is that where is the "1-bit tif data" between the exposure head during exposing?
