I’m developing a Label Printing application for our company that will include support for Black & White and Color Printers.
To simplify development on my part, I’m creating a WinForm with various labels on it that I can position, size, and color as needed. If the End User’s printer is Non-Color, all Pens and Brushes will be black. Otherwise, I will be setting my drawing colors based on the Label control’s color.
I’d like to develop my labels using basic colors that are found in the standard color printer cartridge, so that I don’t wind up causing our company to throw away a cartridge simply because Color Tank #2 has run out (trying to reduce waste and help the environment where I can).
What are the Colors in the tanks? Black, Magenta, Yellow, and Cyan?
If I designed my Labels using these four (4) colors, would I be making good use of the color cartridges or should I stick to combination colors like Red, Blue & Green?
I’d be interested in looking at a simple algorithm that calculates how much color is used, too, if someone knows how to do that.

So…
There is no way to calculate how much of a color is used on a form that I make.
And…
There is no way to balance the amount of colors I select for a printout to load balance the ink in the cartridges.
For now, this is the answer.
If someone can show this to be wrong one day, I’m subscribed for answers, and I’ll be happy to mark a solution …if it works.
