Abstract
Abstract Apparatus and method for making full color prints of a multicolor graphic original. The prints can be duplicates of the original or can be prints having colors for the various colors appearing in the original that have been synthesized to provide prints which are a ''''recoloring'''' of the original. The color data for synthesizing is stored in a permanent, machine readable form for later readout and use in controlling operation of the apparatus in order that the print from the original with synthesized colors can be easily reproduced without having to manually adjust controls for placing the necessary color data into the apparatus to obtain the desired ''''recolored'''' print.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
144 words
Apparatus for transferring color material to a receptive sheet from a photosensitive intermediate containing the material with the degree to Which the color material is transferred being determined by a parameter of the apparatus that is controllable in response to a control signal, the apparatus including a circuit portion responsive to an input signal for providing the control signal for controlling said parameter; a first source of input data including manually settable controls for establishing the input data from said first source; a second source of input data including a stored data reader for providing input data from said second source; and interfacing circuitry connected to said circuit portion and to said first and second data sources for accepting data from a selected one of said two data sources and responding to the accepted data to provide said input signal for said circuit portion
Claim 2
Dependent Claim
144 words
Apparatus for transferring color material to a receptive sheet from a photosensitive intermediate containing the material with the degree to Which the color material is transferred being determined by a parameter of the apparatus that is controllable in response to a control signal, the apparatus including a circuit portion responsive to an input signal for providing the control signal for controlling said parameter; a first source of input data including manually settable controls for establishing the input data from said first source; a second source of input data including a stored data reader for providing input data from said second source; and interfacing circuitry connected to said circuit portion and to said first and second data sources for accepting data from a selected one of said two data sources and responding to the accepted data to provide said input signal for said circuit portion
Claim 3
Dependent Claim
31 words
Apparatus in accordance with claim 1 wherein said stored data reader is a card reader for reading out data stored on a data storage card when presented to the card reader.
Claim 4
Dependent Claim
71 words
Apparatus in accordance with claim 1 wherein the apparatus includes means for providing a signal indicative of the positioning of the color material for transfer to the receptive sheet, said interfacing circuitry connected for receiving said signal from said means and responding thereto to enable said interfacing circuitry to respond to data accepted from said selected one of said two data sources to provide said input signal for said circuit portion.
Claim 5
Dependent Claim
15 words
Apparatus in accordance with claim 1 wherein the parameter is the speed of a motor.
