In an X-ray diagnostic apparatus, the rotation anode of an X-ray tube is placed in rotation at a given low speed prior to examination of an object under examination by fluoroscopy. The marked multicolorant image sheets are batch printed and held in a sheet buffer and interspersed in sequence with the monochromatic marked sheets without interrupting the faster monochromatic marking engine or requiring multiple unnecessary run cost increasing start up and shut down cycles of the multicolorant marking engine. The same texture mapping hardware used for color texturing provides resampled z texturing for sprites with depth or other applications. The method comprises the steps of receiving personal information from a user; transmitting a real name checking code to the user and storing the real name checking code; transmitting the personal information and the real name checking code to a bank; and receiving a real name checking result from the bank.
