Image-forming system, image-forming apparatus, computer program, and image-forming method

摘要

When a DNA ink printing mode is selected, a serial number and a pattern data of DNA is read from an IC tag of a DNA ink cartridge and a fingerprint of a printing person is read by a fingerprint authenticating unit. The pattern of the fingerprint and DNA which have been read are verified with the pattern data of fingerprints and DNA in a memory and personal authentication is carried out. Thereafter, a DNA ink is jetted on to a recording paper, and printing of an image by an image forming ink is carried out. By carrying out printing by such a method, it is possible to specify the printing person who has created the printed matter.
