Abstract

A fluid ejector includes a drop size symbol that is based on the fluid ejector's drop size relative to one or more fixed drop sizes. The drop size symbol is formed by comparing the fluid ejector's drop size to the one or more fixed drop sizes. An image forming device includes a marking fluid ejector that includes a drop size symbol based on the marking fluid ejector's drop size relative to one or more fixed drop sizes. The image forming device forms an image based on the drop size symbol by determining the drop size symbol and then either selecting a marking fluid look-up table based on the drop size symbol, or forming an image correction factor based on the drop size symbol.
