Abstract
Abstract A method of simulating a color image. Firstly, images are displayed and printed, respectively, by means of display device and hard copy unit on the basis of the same image data. Secondly, the image data are subjected to a color conversion process by the use of color conversion parameters having different values from one another, and a plurality of processed images are displayed by the display device. Moreover, from among the processed images being currently displayed there is selected a processed image having substantially the same colors as the image recorded by the hard copy unit, to thereby set the value of the color conversion parameter. Subsequently, a color conversion parameter representing an inverse conversion to the color conversion by way of color conversion parameter which has been set is set into the hard copy unit to thereby print the image based on said image data.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
95 words
A color printing apparatus comprising: printing means for printing image data without any color conversion; converting means for converting said image data according to a plurality of color conversion parameters having different values to produce a plurality of processed images having different colors from one another; display means for displaying said plurality of processed images; and printing means for performing a color conversion on said image data which is inverse to the color conversion of one of said processed images to produce inverted image data and for printing an image from said inverted image data.
Claim 2
Dependent Claim
95 words
A color printing apparatus comprising: printing means for printing image data without any color conversion; converting means for converting said image data according to a plurality of color conversion parameters having different values to produce a plurality of processed images having different colors from one another; display means for displaying said plurality of processed images; and printing means for performing a color conversion on said image data which is inverse to the color conversion of one of said processed images to produce inverted image data and for printing an image from said inverted image data.
Claim 3
Dependent Claim
22 words
The color printing apparatus of claim 1, wherein said display means includes means for displaying said image data without any color conversion.
Claim 4
Dependent Claim
18 words
The color printing apparatus of claim 1, wherein said display means displays said plurality of processed images simultaneously.
Claim 5
Dependent Claim
22 words
The color printing apparatus of claim 1, wherein said converting means includes setting means for setting a value for a conversion parameter.
Claim 6
Dependent Claim
49 words
The color printing apparatus of claim 4, wherein said setting means includes means for selecting the value of a conversion parameter associated with one of said plurality of processed images, and wherein said conversion parameter is set to said selected value for all of said plurality of processed images.
Claim 7
Independent Claim
88 words
A method for color printing comprising the steps of: setting a value for a conversion parameter; converting image data according to a plurality of color conversion parameters having different values to produce a plurality of processed images having different colors from one another; displaying said plurality of processed images; and selecting one of said processed images; subjecting said image data to an inverse color conversion to the color conversion of one of said processed images to produce inverse image data; printing an image from said inverse image data.
Claim 8
Independent Claim
88 words
A method for color printing comprising the steps of: setting a value for a conversion parameter; converting image data according to a plurality of color conversion parameters having different values to produce a plurality of processed images having different colors from one another; displaying said plurality of processed images; and selecting one of said processed images; subjecting said image data to an inverse color conversion to the color conversion of one of said processed images to produce inverse image data; printing an image from said inverse image data.
Claim 9
Dependent Claim
43 words
The method of claim 6, wherein said setting step includes selecting the value of a conversion parameter associated with one of said plurality of processed images, and setting said conversion parameter to said selected value for all of said plurality of processed images.
