Abstract: The present invention relates to a perfumed detergent tablet, the tablet comprising a clay mineral compound, and the perfume comprising less than 0.6% of Schiff-base by weight of the perfume composition.

Abstract: A mouldable photographic material is made up from a thermoplastic base sheet, and a primer coating which provides the key for a photographic emulsion layer. Following exposure and development, a thermoplastic foil is laid over the emulsion layer and bonded in place using an optical quality adhesive.

Abstract: A moldable photographic material (1) is made up from a thermoplastic base sheet (2), a primer coating (3) which provides the key for a photographic emulsion layer (5). Following exposure and developing, a thermoplastic foil (6) is laid over the emulsion layer (5) and bonded in place using an optical quality adhesive.

Abstract: A printing system is disclosed. The system includes a scanner which produces an RGB signal corresponding to a scanned image. The RGB signal is compressed in accordance with a tone curve which is built in reliance upon input provided by the user. The resultant compressed RGB signal is conveyed to a computer. The RGB signal may be modified by a number of interface controls. The RGB signal is driven through a separation engine to produce individual CMYK signals. The separation engine relies upon the interface controls in converting the signal. Image sharpening, or unsharp masking, is performed on resultant CMYK signals to produce a sharp printed image. The image sharpening procedure includes sharpening pixels, calculating T-sums for pixels, calculating gradients for pixels, and smoothing pixels in response to the T-sums and gradient calculations. The resultant CMYK signals may be exported for further data processing, such as integration with text, or they may be sent to a printer to produce high-quality prints.
