Abstract
Abstract An image processing apparatus for allowing a number of image processing techniques to be tested on a single sample sheet at a time. A sample segment of the image may be selected for testing and successively repeated in a sample output for the number of image processing techniques to be tested. The proof page is printed on the printer, with the output of the proof page demonstrating the system operation with the desired image processing technique.

Claim 6
Dependent Claim
79 words
An image processing apparatus for converting grey level image data to a binary encoded output employing a screen, for printing at a binary printer, comprising: means for reading original grey level image data; means for defining a selected area of interest in the image data; means for forming a proof page from repetitions of the area of interest, and means for converting the grey level image data to a binary encoded output employing a different screen for each repetition.
Claim 7
Dependent Claim
140 words
An image processing apparatus for producing a proof image demonstrating the effect of each of a plurality of screen functions on a single page of output, comprising: means for supplying image data; means for selectively defining an area of interest within the image data; means for forming proof image data from the image data, composed of repetitions of the selected area of interest; a screening device for applying a screen or filter function to image data; a screen memory for storing a screen function for use in the screening device; a screen storage storing a plurality of screen functions for the screen memory; and control means for selectively storing selected screen functions to the screen memory to apply at the screening device each of the selected screen functions to each repetition of the area of interest in the example image.
Claim 8
Dependent Claim
140 words
