    Concept of Electromagnetic erasing system is inspired from observation of destructive effects of electromagnetic radiation on color pigments. While ink & pigment producers try to increase resistance of pigments in prolonged exposure to sunlight, this project aims to utilize electromagnetic radiation in a fully controlled reaction inside a machine to break the bonds of color pigments that absorb only a particular range of electromagnetic spectrum. In order to have an efficient system only those CMYK pigments should be utilized that their absorption band is different from paper. In this case, in a similar way as a photochromic or thermochromic material, color pigments start to decompose into colorless products however in contrary to what we expect from a photochromic change, electro erasing would be an irreversible reaction.
