A print quality problem encountered in wide-format inkjet printing is a type of solid-area non-uniformity referred to as “thermal banding.” Thermal banding can be observed, for example, in a print in which a gray or colored border surrounds an area with little or no printing. Although the same tone is specified for all sides of the border, the print density of the top and bottom borders is relatively high, while the density of the side borders between the top and bottom bands is clearly lower. Current theory holds that thermal banding is related to the temperature inside the inkjet head. As the head prints a solid area, it heats up, causing larger drops to be produced. The large drops increase the print density. When a white or mostly-white area is produced, the head cools since little or no jetting occurs. The cool head produces smaller drops and lower print density results. This paper discusses thermal banding and shows how the problem can be quantified using a commercially-available, camera-based image analysis system. The efficacy of head temperature compensation schemes will also be quantified and discussed.
