Abstract
Disclosed is a method and apparatus for printing an image on a print medium with a liquid developer which comprises a liquid carrier and a toner dispersed in the liquid carrier. The printing method has: forming a toner image probably containing the liquid carrier, from the liquid developer; removing the liquid carrier from the toner image; transferring the toner image to the print medium; projecting light radiation on the toner image to be transferred, to measure the optical reflection from the toner image to be transferred; and estimating transfer suitability of the toner image to be transferred, by means of the measured optical reflection from the toner image to be transferred, for appropriately controlling the extent of the removing of the liquid carrier. The printing apparatus has an optical instrument which projects light radiation on the toner image to be transferred and measures the optical reflection from the toner image to be transferred, in order to appropriately control the carrier remover.
