Abstract
Abstract The present invention comprises a contact printer (10) which utilizes a flat tube monitor (30) connected with a computer (40) that permits the image or light array (32) projected by the monitor (30) to be manually and selectively altered in accordance with an operator's evaluation of the image (32) directed upon a negative (20). The operator may selectively dodge, burn, or offset the intensity of the image (32) so that an adjacent area of the negative (20) receives a corresponding alteration. The printer (10) enables the provision of custom contact prints made in accordance with the operator's evaluation of the light array (32) shining through the negative (20) so that the negative (20) is selectively modified acccording to the operator's desire.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
88 words
A contact printer for providing a photographic print in accordance with selective manual control of the contact printer, comprising means for engaging a negative with a clear support, a cathode ray tube disposed adjacent said support and able to emit a light array to the negative, and computer means for controlling the cathode ray tube, the compute means including manual controller means for altering manually, as desired, any selected portion of the light array of the cathode ray tube according to an operator's visual evaluation of the negative.
Claim 2
Dependent Claim
88 words
A contact printer for providing a photographic print in accordance with selective manual control of the contact printer, comprising means for engaging a negative with a clear support, a cathode ray tube disposed adjacent said support and able to emit a light array to the negative, and computer means for controlling the cathode ray tube, the compute means including manual controller means for altering manually, as desired, any selected portion of the light array of the cathode ray tube according to an operator's visual evaluation of the negative.
Claim 3
Dependent Claim
28 words
The contact printer in accordance with claim 1, wherein said engaging means comprises a platen which engages said negative and support to remove atmosphere from about said negative.
Claim 4
Dependent Claim
36 words
The contact printer in accordance with claim 2, further comprising delay timer means for controlling applications and removals of said rolling platen with a predetermined delay of time between each removal and application of the platen.
Claim 5
Dependent Claim
36 words
The contact printer in accordance with claim 1, wherein the cathode ray tube comprises a flat tube monitor which has a flat tube surface so that the surface of the monitor is equidistant from the negative.
Claim 6
Dependent Claim
41 words
The contact printer in accordance with claim 4, wherein the altering of the light array comprises altering pixels of the light array by reducing the light intensity emission of the pixels so that darker areas are added to the light array.
Claim 7
Dependent Claim
41 words
The contact printer in accordance with claim 4, wherein the altering of the light array comprises altering pixels of said light array by increasing the light intensity emission of the pixels so that brighter areas are added to said light array.
Claim 8
Dependent Claim
20 words
The contact printer in accordance with claim 4, wherein the cathode ray tube effects a black and white light array.
Claim 9
Dependent Claim
18 words
The contact printer in accordance with claim 4, wherein the cathode ray tube effects a colored light array.
Claim 10
Dependent Claim
43 words
The contact printer in accordance with claim 8, wherein alteration of the colored light array is effected by changing selectively the color and intensity of pixels to provide offset pixels in order to control the intensity and color composition of said light array.
Claim 11
Independent Claim
156 words
A method for making photographic prints by selectively controlling the intensity of light directed upon a negative, comprising the steps of: (a) providing a contact printer with a cathode ray tube which is connected with computer means responsive to a control mechanism, (b) placing the negative on a clear support of the printer so that light emitted from the tube passes through the negative, (c) utilizing the control mechanism to alter manually and selectively any portion of the light array emitted by the cathode ray tube so that light of the selected portion shining through the negative is altered according to an operator's visual evaluation of the negative with said light array passing therethrough, and (d) actuating the cathode ray tube via the control mechanism so that a print medium adjacent the negative receives the altered light from the cathode ray tube via the negative, to provide a print in accordance with the evaluation and alteration.
Claim 12
Independent Claim
156 words
A method for making photographic prints by selectively controlling the intensity of light directed upon a negative, comprising the steps of: (a) providing a contact printer with a cathode ray tube which is connected with computer means responsive to a control mechanism, (b) placing the negative on a clear support of the printer so that light emitted from the tube passes through the negative, (c) utilizing the control mechanism to alter manually and selectively any portion of the light array emitted by the cathode ray tube so that light of the selected portion shining through the negative is altered according to an operator's visual evaluation of the negative with said light array passing therethrough, and (d) actuating the cathode ray tube via the control mechanism so that a print medium adjacent the negative receives the altered light from the cathode ray tube via the negative, to provide a print in accordance with the evaluation and alteration.
Claim 13
Dependent Claim
29 words
The method in accordance with claim 10, futher comprising the step of altering, via the control mechanism, the color of the light array emitted by the cathode ray tube.
Claim 14
Dependent Claim
31 words
The method in accordance with claim 10, further comprising the step of providing a flat cathode ray tube so that the tube emits light from a source equidistant from said negative.
Claim 15
Dependent Claim
36 words
The method in accordance with claim 12, wherein said utilization of control mechanism to alter manually and selectively the light array comprises altering a portion of said light array so that a dark area is included.
Claim 16
Dependent Claim
39 words
The method in accordance with claim 12, wherein said utilization of the control mechanism to alter manually and selectively the light array of the cathode ray tube comprises altering the light array so that a light area is included.
Claim 17
Dependent Claim
57 words
The method in accordance with claim 12, wherein the utilization of the control mechanism to alter manually and selectively the light array of the cathode ray tube comprises changing selectively the color and intensity of pixels to provide offset pixels in said light array in order to control the intensity and color composition of said light array.
Claim 18
Dependent Claim
20 words
The method accordance with claim 12, further comprising the step of utilizing the computer means to set an exposure time.
Claim 19
