Abstract
A thermal dye transfer apparatus includes an array of laser diodes which illuminate a dye carrying donor. The donor absorbs heat from laser light and dye transfers by sublimination from the donor to the receiver to form pixels. Light from each diode laser is modulated to have different pixel density levels.
