The postage stamp, a small work of art, made by using the InfrareDesign® method, hides extended information about the content of its issue

A postage stamp is a security that goes down in history. The stamp we are presenting was designed and issued in Croatia, EU, on 24 September 2021, on the occasion of the 100th anniversary of the Otorhinolaryngology Clinic in Croatia. This stamp contains new values through IRD, and that is exactly what we show and offer to philatelists. The stamp "100 years of otorhinolaryngology" has artistic beauty and scientific innovation in the development of twin colorants. In the visual solution of the stamp are embedded hidden graphics that expand the information about the anniversary. Two images are demonstrated in the same space of the stamp, which gives an advantage because it increases the space for communication of a small graphic art product that is printed and multiplied with the IRD procedure. It is a novelty in messaging that is essential in stamp design, with an emphasis on its security features. The stamp has two levels of viewing, for two light areas. The level that is not visible to our naked eye contains data that hides the author’s mark, the printer’s mark, and the institution that bears copyright. The discovery and development of the new INFRAREDESIGN® method offered new experiences in design documents and securities. IRD is an extension of the technology of making and protecting the stamp from counterfeiting because the visible image of the stamp is closely connected to the infrared image. Two images are printed in the same place: a visible image for the naked eye and another image that is recognizable by an infrared detector. The two graphics are inseparable and are widely used in the areas of proving the authenticity of a work of art.
