Purging print cartridges

I've occasionally had the need to purge print cartridges, just for one colour. I've been resurrecting a couple of dodgy cartridges, am using the Tesco colour re-fill kit - ~£10 and good for a couple of re-fills. My printer is an HP960c. However, I need to purge just one of the colours, e.g. the red.but for the 3 so called colours which colour should I select? The printed colours are made up of mixtures of the colours in the cartridge. Not explaining this very well. Anyone follow my line of thought an have any suggestions to make?

Are you able to select which colour(s) to purge? In my experience, although not with that printer model, the purging is only available with all the cartidges, including black.

If you can purge individual cartridges, the red is produced from magenta and yellow.

For other colours:

Green is from cyan and yellow.

Purple/violet is from magenta and cyan.

Blue is from cyan with a small amount of magenta.

Orange is from yellow and a small amount of magenta.

Brown is orange (as above) with a small amount of cyan or black.

Not quite folks. I actually want to just print, say magenta, until I get what I want. Then, say cyan or even yellow. But what colour, or number combination should I choose in say Paint, just to exercise one of the "colours" from the cartridge?

Yes but I just want to, in turn, print the cyan then the yellow and finally the magenta. Not necessarily in that order. Is it possible to type in the colour in paint or PSP and just print a block that exercises just the one print head jets. I didn't think I'd described it properly.

Ok doug, in Paint go to custom colours. Now, the thing is that we have to work in both additive (RGB) and subtractive (YMC) systems to do this.

So, pick one of the basic colours as near as you can to, say, magenta. What we want in the boxes below the colour palette is to saturates (i.e. 255) red and blue with green at zero. Move the point around if necessary to achieve this. Add this colour to custom colours.

Similarly, for cyan try to get green and blue at 255 and red at zero

For yellow, red and green at 255 and blue at zero.

When you have each of these saved in custom colours you can use any or all of them to infill solid colour in a box or something you instruct it to.

Hope I've understood and that you can follow this :)
