Line art (color or gray scale)
Primarily solid colors or smooth gradients (color or gray scale)
Continuous-tone photographs (color or gray scale)
Option 0 is the fastest. It generates strong, but not particularly accurate, colors. There may be some fairly sharp color transitions in this mode.
Option 1 generates more accurate colors, but is slower.
Option 2 generates the most accurate colors, but is considerably slower.
Note that any of the modes may be used with either color or black & white output. If black and white output is requested, but a color mode used, composite color will be printed. This generally offers smoother tone, but less purity of gray or black, than pure black ink. Furthermore, it is possible to tune the color of the gray (to achieve warmer or cooler effects) using the color controls in this fashion.
