Do you print this yourself or send it out?
I don't think you can alias cyan, magenta or yellow in ID so If printing locally I would redefine the color in your RIP
While you were crystal clear, I'm having trouble envisioning all your work actually being cyan and black. By chance do you merely design in cyan and instruct the "printer" to use a Pantone (or Spot)?
No, I don't print this myself.
I do design this as cyan and black, I have a palette w many CMYK mixes of the two but no M or Y and use duotones n other tricks for the images. There are a few stray pixels, but printer just uses cyan and black plates from seps.
Pardon also the terminology. I wish to swap "CHANNELS" so I may view in Indesign (or Illustrator, 2/3 of files that make up this ID file are Illustrator files) for any unexpected color shifts, esp to avoid pink instead of the light blue in some parts.
There are far too many source images and files for that solution. Further, as mentioned, I have many a swatch that is part cyan and part black, for instance: C 100, M 0, Y 0, K 20. I would have to alias all of these iterations to spot colors as well.
There is a plugin that may do the job for Illustrator: Phantasm supposedly can swap channels.
