Abstract: A method for making matched backgrounds for images of objects with the backgrounds having continuously varied gradations of tone. A continuous tone step tablet negative is positioned on a scanning drum of a laser scanning device. A piece of lithographic film is positioned on a receiving drum of the laser scanning device. A first photo mechanical screen is positioned over the piece of film. An image of the continuous tone step tablet negative is transfer-scanned to the piece of film through the screen while enlarging from 225% to 1800% of original size. The above steps can be repeated using different screen angles for producing sufficient plates for desired color combination. The pieces of film are then developed. The piece of film can be masked at a desired location with the mask appropriate to the image of the object. The developed pieces of film can be printed each with a different color ink to produce the backgrounds.
