Sažetak
Safety graphics on drug packaging are presented using infrared colorants according to the recipe for VZ twins for offset printing. The mathematical model of the individual shape of raster (screen) elements, “the FourHorns” (FH), is presented here along with the performance solution in PostScript. Safety procedures have been expanded with linear typography print, but by using low resolution screens on the border of recognition. The design was applied in the print on drug packaging subject to different weather conditions which affect and change the color tone of V and Z twins during longer time periods. The visual design (V) is shown and transformed into near infrared spectrum (Z) using the method of digital animation. The presentation is based on the methods of creating animated movies by combining eight photographs which were made using a forensic camera with light filters for the range from 400 to 1000 nanometers. The visual and near infrared absorption of sunlight is shown in continuity, including the Z1 and Z2 area of wavelengths.
