Resourceful Ink Usage

Yesterday, the black ink cartridge went out in Eagle’s printer and today I returned with a replacement.  In the mean time, the department’s need of partials would not be stopped and the staff came up with a fix by printing out their normal forms rendered in pure red, blue, and green in an attempt to shift to the color cartridge.  While creative, there are two problems:

1) Color ink is stupidly expensive
2) Ink is generally CYMK because it’s subtractive rather than RGB which is additive
