A method of producing a composite image on an image recording medium from first and second component images, represented by digital image data, comprising the steps of converting the digital image data of each image into electromagnetic radiation image data; and forming the composite image by successively exposing the recording medium to the electromagnetic radiation image data of the first and second images so that the images are created on the medium in overlapping relationship to form a join region. The medium is doubly exposed, first by the image data of the first image and then by the image data of the second image. The intensity of the electromagnetic radiation representing the first image is progressively ramped off in the join region and the intensity of the electromagnetic radiation representing the second image is progressively ramped on in the join region.

Method and apparatus for creating a composite image by the tiling of

A method of transforming input image data into output image data in order to form an output image which comprises a plurality of specified image areas is provided. The method comprises providing a plurality of different sets of color transform look-up tables, associating the different sets of look-up tables with the plurality of specified image areas. The output data is coded to identify an associated one of the different sets of look-up tables responsive to one of the specified image areas for which the output data is being obtained. A color transformation is then performed on the input image data to obtain the output data using one of the different sets of look-up tables identified by the coding. An apparatus for carrying out the method is also provided.
