Spot colorant twins for infrared security print of topographic maps

The importance of topographic map press lays in the protection of the data accuracy. Modern scanning technologies and the digital press create forgeries which make it hard to identity the original document with correct information. The possibility of making a topographic map secure as a state document is demonstrated with the press model developed for twin spot colorants with the management in two spectrums: the visual and the near infrared. The new model for the extraction of the infrared condition with digital print, according to the Infraredesign theory, is the basis for the formulation of the dyes mixing for the eight color infrared protected press. Brown, green, blue, ocher and red twin spot colorants are mixed, specifically for he security printing of topographic maps. The paper defines the use of infrared technology for the design of dual information on multicolour spot print for topographic maps security print.
