An inklayer image transparency system of the present invention has a graphics controller or processor, memory, and a display device that may be external to the inklayer image transparency system. The graphics controller is suitable for receiving signals (e.g. an address signal and a transparency control signal) and for providing image information to the display device. The memory is divided into at least two memory sections including a first memory section for storing foreground image information and a second memory section for storing background image information. A single address signal received by the graphics controller is used for simultaneously fetching the foreground image information from the first memory section and the background image information from the second memory section. A transparency control signal having a nontransparent state and a transparent state is used to control whether the foreground image or background image is displayed. The foreground image information is sent for display on the display device when the transparency control signal is in the nontransparent state and the background image information is sent for display on the display device when the transparency control signal is in the transparent state.
