change color swatch to other color swatch
Hello friends
I have a document with magenta color (magenta=100) and I am looking for a script that will turn it into a spot color whose name will be "cutcontour" (magenta=100 too)

Hi @aviel222, here is a modified version of the script I wrote for you on this thread. I think it will do what you want. Try to understand what is happening in the changeColor function. You can configure what you want to do there to some extent. Note that currently, this script will create the "CutContour" spot colour if it isn't in document already (see the call to my makeSpot function).

/**
* Replaces colors of items in document.
* Currently configured via the 'changeColor'
* replacer function to:
* (a) change stroke [C=0, M=100, Y=0, K=0] to 'CutContour' spot.
* (b) not change [C=100 M=0 Y=0 K=0] or [C=0 M=100 Y=0 K=0] (even in spot color)
* (c) change 10% black or lighter to white
* (d) change anyhting else to 100% black

* Note: you can customise which colors are excluded by editing the `changeColor` function or writing your own replacer.
