Abstract: A digital printing method for printing photographic quality images employs a printhead having a plurality of recording elements at least some of which recording elements are arranged in a line. A recording sheet is moved relative to the printhead to form an image on the recording sheet. The recording sheet has parallel spaced side edges. A page of image data to be printed on the recording sheet is provided that represents an image having top, bottom and side edges to establish a substantially rectangular image. The image is formed on the recording sheet through lines or bands of recording sequences that form the image so that the top side edge of the image is formed at an oblique angle to the side edges of the recording sheet wherein the oblique angle is between 15 degrees and 75 degrees. Alternatively, the top side edge of the image is formed perpendicular to the side edges of the recording sheet through formation of the image by swaths of recording sequences that are oblique to the top edge of the image.

Abstract: An ink jet printing method, including the steps of: A) providing an ink jet printer that is responsive to digital data signals; B) loading the printer with an ink jet recording element; C) loading the printer with a color ink jet ink set having: (i) a magenta ink having a carrier and a water-soluble, transition metal complex of an 8-heterocyclylazo-5-hydroxyquinoline dye; (ii) a yellow ink having a carrier and a water-soluble yellow dye; (iii) a cyan ink having a carrier and a water-soluble cyan dye; and (iv) an orange and/or green and/or violet ink having a carrier and a water-soluble orange and/or green and/or violet dye; and D) printing on the image-receiving layer using the inkjet ink set in response to the digital data signals.

Abstract: A color ink jet ink set for color printing including: (a) a magenta ink having a carrier and a water-soluble, transition metal complex of an 8-heterocyclylazo-5-hydroxyquinoline dye; (b) a yellow ink having a carrier and a water-soluble yellow dye, (c) a cyan ink having a carrier and a water-soluble cyan dye, and (d) an orange and/or green ink having a carrier and a water-soluble orange and/or green dye.

Abstract: A method for correcting for exposure in a digital image which was captured by an image capture device and which is to be printed on a printer which forms monochrome or color images, on a medium, includes providing a plurality of exposure and tone scale correcting nonlinear transforms, each such nonlinear transform being unique to an exposure condition and which corrects exposure and tone scale for a digital image captured by the capture device for such unique exposure conditions and to be printed by the printer; and selecting the appropriate nonlinear transform from the plurality of nonlinear transforms and using such selected transform to transform the digital image and produce a new digital image which is corrected for exposure and tone scale when printed from the printer.

Abstract: A color ink jet ink set for color printing; comprising(a) a first ink comprises a carrier and a bridged aluminum phthalocyanine pigment as a cyan colorant;(b) a second ink comprising a carrier and a quinacridone pigment as a magenta colorant;(c) a third ink comprising a carrier and a non-benzidine yellow pigment as a yellow colorant; and(d) at least one additional ink comprising a carrier and a colorant which is:(i) an orange colorant comprising a Naphthol AS, .beta.-Naphthol, diketopyrrolo-pyrrole or a disazopyrazolone pigment;(ii) a green colorant comprising a copper phthalocyanine green or a triarylcarbonium pigment; or(iii) a violet colorant comprising a quinacridone, triarylcarbonium, benzimidazolone, or a dioxazine pigment.

Abstract: A method for characterizing a response function of an output device, the method comprises the steps of producing a test image on the output device with a set of one or more test patches having known code values; obtaining one or more captured images of the test image using a digital camera; determining colorimetric values for each of the test patches in the captured images using a known response function of the digital camera; and determining a response function of the output device which relates the known code values to the determined colorimetric values.
