Abstract
A method compensates for runout errors in a web printing system. The method includes identifying runout error at a first roller driving a web of printable media, generating a runout compensation value corresponding to the identified runout error, identifying a velocity of the moving web with reference to encoder output corresponding to an angular velocity of the first roller and the generated runout compensation value, and delivering a firing signal to a print head proximate the first roller to energize the inkjet nozzles in the print head and eject ink onto the web at a position corresponding to the computed web velocity.
