Script to add suffix to spot channel names with sequential numbers?

[mariap81355074]

Is it possible to ignore the top channel which is usually called 'grey' when in grey mode, and rename all others to have a number as a suffix, so spot channels would be like:

Grey

Red 185

Yellow 101

Black

and then after running the script it'd look like

Grey

Red 185 - 1

Yellow 101 - 2

Black - 3

Many thanks in advance 😄

Try this

var ch = app.activeDocument.channels;

var n = 0;

for (var i = 0; i < ch.length; i++)
    {
    if (ch[i].kind != ChannelType.SPOTCOLOR) continue;

    ++n;

    ch[i].name += " - " + n;
    }

Thank you so much 🙂

If I wanted it as a prefix instead of a suffix how would I go about amending the script?

ch[i].name = n + ' - ' + ch[i].name
