Cyan Dye

Crystallized Cyan Toner Dye

This is the crystallized cyan toner dye, sulfonated copper phthalocyanine. These crystals were formed by collecting a dropplet of the ink from a cartridge and allowing it to dry on a microscope slide. The colors result from the combination of the color of the dye and the interference color created by the crystal structure and the thickness of the crystal.
