   NOTE:
   Colors the machine can print and colors you see on a monitor are different. Computer monitors can display millions of color as RGB (Red, Green, Blue). The color laser machine uses a 4-color printing process of CMYK (Cyan, Magenta, Yellow, Black). The machine uses these 4 colors to create as many colors as possible, but may not be able to reproduce the colors on your monitor.
   
   Additionally, what we see on a computer monitor is emitted light, while what we see on a printed document is reflected light. Due to this difference, we can't get a 100% accurate match. The nature of both types of light and how our eyes react, makes color matching between them a bit of a challenge. Even LCD monitors are different from CRT monitors, as the brightness and contrast differ greatly.
   
   The paper brightness and smoothness will affect the colors you see printed on the page. The colors you see on the page may look different in natural light, soft white light, and fluorescent light.
    

   The images you printed in STEP 1 are ...	Reference RGB value
   	Red	Green	Blue
   reddish (Case A)	-8	4	4
   yellowish (Case B)	-4	-4	8
   pinkish (Case C)	-4	8	-4
   greenish (Case D)	4	-8	4
   bluish (Case E)	4	4	-8
   lightly bluish (Case F)	8	-4	-4
