Abstract
Abstract A method of adjusting process black and a driver thereof. The method includes converting a part of process black data into mono black data. Accordingly, a user can arbitrarily adjust a ratio of process black to obtain a more natural output image and print the output image in process black and mono black, thereby reducing the consumption of ink or a colorant contained in process black.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
68 words
A method of adjusting process black when printing a color image, comprising: converting a part of data for process black into data for mono black; and adjusting a ratio for the mono black data, wherein a value of the mono black data is obtained by multiplying a value of the initial process black data by the adjusted ratio for the mono black data as selected by a user.
Claim 2
Independent Claim
68 words
A method of adjusting process black when printing a color image, comprising: converting a part of data for process black into data for mono black; and adjusting a ratio for the mono black data, wherein a value of the mono black data is obtained by multiplying a value of the initial process black data by the adjusted ratio for the mono black data as selected by a user.
Claim 3
Independent Claim
126 words
A method of adjusting process black when printing a color image, the method comprising: checking if processing black is to be performed on an output image; calculating a first process black value using a cyan value C, a magenta value M, a yellow value Y, and a black value K regarding the image to be output and the information being provided together with the image; calculating a mono black value at a particular ratio with respect to the first process black, the ratio of the mono black value being determined by a user; calculating a second process black value by subtracting the mono black value from the first process black value; and outputting the image using the mono black value and the second process black value.
Claim 4
Independent Claim
126 words
A method of adjusting process black when printing a color image, the method comprising: checking if processing black is to be performed on an output image; calculating a first process black value using a cyan value C, a magenta value M, a yellow value Y, and a black value K regarding the image to be output and the information being provided together with the image; calculating a mono black value at a particular ratio with respect to the first process black, the ratio of the mono black value being determined by a user; calculating a second process black value by subtracting the mono black value from the first process black value; and outputting the image using the mono black value and the second process black value.
Claim 5
Dependent Claim
55 words
The method of claim 2 , wherein overall color values are calculated by subtracting the first process black value from the C, M, and Y values to obtain subtraction values and adding the second process value to the subtraction values, respectively, the overall color values being used when printing the output image in process black.
Claim 6
Dependent Claim
32 words
The method of claim 2 , wherein when printing the image in process black, the overall black value is obtained by adding the mono black value to the initial black value K.
Claim 7
Dependent Claim
63 words
An image outputting driver to control an output of an image outputting apparatus, the image outputting driver comprising: a first selector which allows a user to select whether processing black is performed on the image; and a second selector which allows the user to select a ratio of process black when the first selector selects to carry out processing black on the image.
Claim 8
Dependent Claim
63 words
An image outputting driver to control an output of an image outputting apparatus, the image outputting driver comprising: a first selector which allows a user to select whether processing black is performed on the image; and a second selector which allows the user to select a ratio of process black when the first selector selects to carry out processing black on the image.
Claim 9
Dependent Claim
32 words
The image outputting driver of claim 5 , wherein the first selector provides a selection window to select whether processing black is carried out on a text, a graphic, or a picture.
Claim 10
Dependent Claim
29 words
The image outputting driver of claim 5 , wherein the second selector allows the user to select a ratio of process black within a range between 0% and 100%.
Claim 11
Dependent Claim
27 words
The image outputting driver of claim 7 , wherein a ratio of the mono black is obtained by subtracting the ratio of the process black from 100%.
Claim 12
Dependent Claim
48 words
The image outputting driver of claim 7 , further comprising a process black calculator which calculates and reflects ratios of process black and mono black when the user selects the printing of the output image in a particular ratio of process black using the first and second selectors.
Claim 13
Dependent Claim
102 words
The image outputting driver of claim 9 , wherein the process black calculator calculates a first process black value using the C, M, Y, and K values, calculates a mono black value, calculates a second process black value by subtracting the mono black value from the first process black value, and applies the second process black value and the mono black value when printing the output image, the C, M, Y, and K values being provided from information together with the output image, and the mono black value whose ratio is determined based on the first process black value by a user.
Claim 14
Dependent Claim
26 words
The image outputting driver of claim 10 , wherein the first process black value corresponds to the minimum value of the C, M, and Y values.
Claim 15
Dependent Claim
44 words
The image outputting driver of claim 10 , wherein the overall color values are calculated by subtracting the first process value from the C, M, and Y values to obtain subtraction values and adding the second process black value to the subtraction values, respectively.
Claim 16
Dependent Claim
25 words
The image outputting driver of claim 10 , wherein an overall black value is calculated by adding the mono black value to the K value.
