ABSTRACT:
An apparatus for making copies of a colored master has a color monitor which can produce a color image of the master. The monitor is provided with a circuit for turning a portion of the monitor screen black-and-white and adjusting the size and/or position of the black-and-white portion of the screen. The black-and-white portion of the screen is positioned adjacent to a critical area of the color image so that the density and color of the image can be evaluated. The monitor further includes a circuit for adjusting the density and color of the image.
