Abstract
A printhead in a digital printing includes an array of light sources for exposing a photosensitive medium moving past the printhead. Artifacts are reduced in a high-speed print mode by defining first and a second power level control values that differ by at least 20%. The light sources used to print odd-numbered image pixels are activated responsive to the first power level control value and the light sources used to print even-numbered image pixels are activated responsive to the second power level control value.
