So we want the black ink to affect the darkest parks of the image, the green, the shadows, & the mauve the highlights. So we need to adjust the three curves by clicking on the curves box. First the blacks so that they only impact the blacks - see how the greens are just starting to show.

Then adjust the greens to affect the mid tones

Then boost the mauves in the light tones

At this stage save your images as a psd file. You can come back and adjust the mix, the colours or the curves at any time by going to > Image > Mode > Duotones to reopen the dialogue box.
Finally to save as a jpg, you need to reconvert in to RGD by going > Image > Mode > RGB Color
Phew
