Abstract: Optical density is enhanced on print media darkened by exposure to electromagnetic radiation. The print media is divided into at least one track. A defocused spot of electromagnetic radiation is created within the track. The defocused spot of electromagnetic radiation darkens the print media within the track.

Abstract: A method of an embodiment of the invention optically writes a plurality of image data files on an optically writable data side of an optical disc. The method optically marks a plurality of thumbnail images on an optically writable label side of the optical disc. Each thumbnail image corresponds to one of the image data files.

Abstract: Briefly described, embodiments of this disclosure include light directed imaging layers, light directed image recording media, and methods of preparation of each. One exemplary embodiment of the light directed imaging layer, among others, includes a matrix; a developer substantially dissolved in the matrix; a color former that is substantially insoluble in the matrix at ambient conditions and is substantially uniformly distributed in the matrix; and a pigment antenna uniformly distributed in the matrix, wherein the pigment antenna has the characteristic of absorbing an imaging radiation, and wherein the pigment antenna has a diameter less than the wavelength of the imaging radiation.

Abstract: A radiation image-able coating includes a first phase including a radiation curable polymer matrix and an activator disposed in the radiation curable polymer matrix, a second phase insolubly distributed in the first phase, the second phase including a color-former, and an antenna dye package distributed in at least one of the first and second phase, wherein the antenna dye package includes at least a first antenna dye having a first absorbance maximum wavelength and a second antenna dye having a second absorbance maximum wavelength.

Abstract: A radiation image-able coating includes a first phase including a radiation curable polymer matrix and an activator disposed in the radiation curable polymer matrix, a second phase insolubly distributed in the first phase, the second phase including a color-former, and a hybrid antenna dye package distributed in at least one of the first and second phase, wherein the hybrid antenna dye package includes at least a first antenna dye having a high extinction coefficient and a second antenna dye having a low extinction coefficient.

Abstract: Imaging layers, image recording media, and methods of preparation of each, are disclosed. One exemplary embodiment of the imaging layer, among others, includes a matrix; a radiation absorbing compound dissolved in the matrix; an aromatic compound dissolved in the matrix; a color former; and an activator. One of the activator and the color former is dissolved in the matrix and the other of the activator and the color former is substantially insoluble in the matrix at ambient conditions and is substantially uniformly distributed in the matrix.

Abstract: Imaging layers, image recording media, and methods of preparation of each, are provided. One exemplary embodiment of the imaging layer, among others, includes a matrix, a radiation absorbing compound dissolved in the matrix, at least two activators substantially dissolved in the matrix, and a color former. The activators can include a primary activator having a higher acidity than a secondary activator. In addition, the primary activator has a lower solubility in the matrix than the secondary activator. The color former is substantially insoluble in the matrix at ambient conditions and is substantially uniformly distributed in the matrix.
