    摘要： Infrared radiation-sensitive heterocyclic oxonol compounds have been found that are represented by Structure DYE as follows: wherein R is a secondary or tertiary amine, R1 and R2 are independently heterocyclic or carbocyclic aromatic groups, and M+ is a monovalent cation, provided that at least one of R, R1 and R2 contains at least one heterocyclic group. These compounds have a &lgr;max above 700 nm and are can be used in a number of photosensitive or heat-sensitive imaging materials.

    摘要： A print media has a visible image and a plurality of invisible encodements comprising data printed over it in a hierarchy order, wherein the encodement of the highest order represents a replacement or edited version of the data of lower order encodements. Apparatus and methods provide effectively editing of an existing invisible encodement printed on media with a material sensitive to a first light wavelength by printing an edited or replacement encodement over it with a material sensitive to a second light wavelength of higher order in the hierarchy. Apparatus and methods also provide for selectively reading the highest order encodement, all of the encodements or selected ones of the encodements.

    摘要： A test target having N invisible test data encodements (660-66N, 740-74N, 74′0-74′N) each comprising test data printed over the surface of test print media media in a defined spatial order printed in invisible ink by a printer under test. The invisible ink print quality of the printer is determined by the ability of an invisible encodement reader to decode certain of the N invisible encodements (660-66N, 740-74N, 74′0-74′N). In a first preferred embodiment, a test print media is prepared by pre-printing or coating a media surface with an invisible ink that is sensitive to the same wavelength of light as the printer ink in a plurality N of areas on the media surface providing step background densities (580-58N) ranging from no applied ink to maximum printer ink density in a test tablet manner In the test mode, N test data files are printed as N invisible encodements (660-66N) in the corresponding N areas (580-58N) thereby creating a test target that is to be read by the reader. It is presumed that the print quality that the printer is capable of achieving is degraded if fewer than a predetermined number of encodements (660-66N) are readable, and the invisible ink is replaced or replenished. In a second preferred embodiment, the test target comprises N invisible encodements (740-74N, 74′0-74′N) differing from one another in a step tablet manner printed by the printer (16) under test. The encodements (740-74N, 74′0-74′N) are read and decoded to the extent possible using the reader. The particular ones of the encodements (740-74N, 74′0-74′N) that can be accurately decoded provide a measure of the print quality that the printer is capable of achieving.

    摘要： An element for cleaning processing solutions contained in a radiographic film processor is disclosed. The element is comprised of a transparent film support and hydrophilic colloid layers coated on opposite sides of the film support. An infrared opacifying dye is contained within the element capable of reducing specular transmission through the element before, during and after processing to less than 50 percent, measured at a wavelength within the spectral region of from 850 to 1100 nm. A processing solution soluble colorant can be contained in one or more of the hydrophilic colloid layers.
