Abstract
Drawing is a simple method of obtaining pictures. Its feature is two stages image, usually high reflection rate from substrate and low reflection from deposited ink. A pair of soft ball pens with similar visual but different NIR spectral properties are chosen. In visual part they obtain very close reflective properties, meaning color experience, but in NIR they differ. At quality pen products the line width is mainly constant as well as the ink coverage. This facilitates to introduced to NIR technology and InfrareDesign to manage the system of twin pairs and to display a visual image, and a secondary image instrumentally visualized in NIR domain. Selected double stage images and dual drawings are customized and prepared for graphic reproduction reproduction in edition supporting dual images implementation.
