Method of and apparatus for simulating object image to be printed
First Claim
1. An apparatus for simulating an object image to be printed which is obtainable by modifying a given original image data into a modified image data and then printing said object image using a process scanner on the basis of said modified image data, said apparatus comprising:
- (a) means for inputting said original image data,(b) means for variably designating modification conditions employable in modification of said original image data,(c) means coupled to said means (a) and (b) for modifying employable in modification of said original image data,(c) means coupled to said means (a) and (b) for modifying said original image data into said modified image data in accord with said modification conditions,(d) means for storing reference image data set by earlier printing a reference image and then confirming that the printed reference image has desired image characteristics,(e) display means for displaying one or more images on the basis of given image data, and(f) means coupled to said means (c), (d) and (e) for transmitting said modified image data and said reference image data to said display means as said given image data in order to display on said display means first and second images on the basis of said modified image data and said reference image data, respectively, so that said first and second images can be visually compared with each other.

Abstract
An images simulator (20) comprises a storage unit 31 for storing reference image data by which reference image of proper color and gradation are reproduced in printing process. Original image data (I (B, G, R)) are read by an image reading unit (11) and processed by an image processing unit (13) under reproduction conditions set in a condition setting unit (12). A proof image is displayed on a CRT (30) along with the reference image as a function of the original image data and the reference image data, respectively. An operator adjusts the reproduction conditions such that color and gradation of the proof image conform to those of the reference image.

4. An apparatus for simulating an object image to be printed on a process scanner, the apparatus comprising:
-
(a) means for supplying original image data by which said object image is reproduced, (b) means for setting reproduction conditions concerning color and gradation for said original image data, (c) means for processing said original image data under said reproduction conditions, thereby generating modified image data, (d) means for storing reference image data by which a reference image is reproduced, (e) display means for displaying a proof image simulating said object image as a function of said modified image data and for displaying said reference image data, and (f) means for adjusting said reproduction conditions, wherein adjusting data are manually input such that color and gradation of said reference image conform to those of an adjusted proof image which is displayed on said display means as a function of said original image data under said reproduction conditions adjusted by said adjusting data. - View Dependent Claims (5)

6. A method of simulating an object image to be printed on a process scanner, the method comprising the steps of:
-
(1) preparing reference image data by which a reference image is reproduced; (2) preparing original image data by which said object image is reproduced; (3) preparing reproduction conditions concerning color and gradation for said original image data, (4) processing said original image data in accordance with said reproduction conditions, to thereby generate modified image data, (5) displaying a proof image simulating said object image on a display means as a function of said modified image data and displaying said reference image data, (6) adjusting said reproduction conditions, and processing said original image data under adjusted reproduction conditions, to thereby generate said modified image data, and (7) executing repeatedly said steps (5) and (6) such that color and gradation of said proof image conform to those of said reference image. - View Dependent Claims (7, 8, 9, 10, 11, 12)
