This is awesome thank you!
And whilst I am glad my ruse worked.. my grasp of illustrator is indeed limited.
I’m in the print / proof workspace. I got me Pantone Green C in my swatch zone… but how do i select just the cyan? I can obviously turn off the YMK in the separations window when I have the overprint preview box checked. But as this is a flattened jpeg or tiff.. i can’t work out how to actually select just the cyan objects. The whole rectangular outline of the whole jpeg is selected. Gah!
Thank you for your help.. this is a real doosie for me.. I have hundreds of maps to adjust. waah.
