Abstract
A method of providing drive signals to an illuminator module having a plurality of channels in a printing application. Binary image data including image bits is provided from a data source to the illuminator module. Each image bit is converted to a multi-bit amplitude value within the illuminator module, wherein the conversion of each image bit to the multi-bit amplitude value depends at least on a value of the image bit and which channel is associated with the image bit. Pulse width modulation (PWM) may be applied to the drive signals using programmable transition delays. Apparatus for performing the aforementioned method are also disclosed.
