Abstract: A photostorage and emission material with technology for altering color and methods of formulating luminescent inks for color separation of the artwork and printing full color pictorial images with realistic depth. The resulting full color pictorial images are visible in both conditions of reflected light in daylight as well as similar full color emission light in darkness. When the pictorial images are exposed to a bright light source to achieve complete excitation of the photostorage and emission material, the pictorial images exhibit high initial brightness and long glow duration time in darkness. The photostorage and emission inks are utilized in process color separations for printing pictorial images with standard equipment in the printing industry.

Abstract: A photostorage and emission material with technology for altering color and methods of manufacturing same. The component is composed of at least one luminescent material and at least one fluorescent colorant and/or optical brightener component. The luminescent component absorbs energy from a light source and continues to re-emits the light energy in or first wavelength spectrum when the light source is removed. This energy excites another component including a fluorescent colorant and/or optical brightener material which is excited by absorbing light at the first wavelength spectrum and re-radiating the absorbed light at a second wavelength spectrum. The optical properties of each material are closely matched so that the emission spectrum of luminescent materials stimulate the excitation spectrum of the fluorescent and/or optical brightener materials.
