Scripting for Changing one Spot Colour to Another

[Bria5EB3]

Hi,

I want to create a script that will change everything in a file or in a Layer called "Artwork" (if that's easier) to a spot colour Black which is just K. So for example if I have a file and the artwork is just PMS Yellow 115 U and all of the artwork is 100% 115 U but there is a part that is 50% 115 U - could a script change all of the 115 U to a Spot Black including making the 50% 115 U to 50% Spot Black? Spot Black must be C: 0, M: 0, Y: 0, K: 100.

We produce film for plate and when this is done everything must only be Black (K) and I'm thinking based on your other Script you made, perhaps one could be made to make everything in a document the one Black spot colour.

 

So basically - the colour changer script would work like this:

-An Artwork that is all just in 100% PMS Yellow 115 U > Change to 100% Spot Black (100% K)

-An Artwork that is 100% 115 U, 50% 115 U > Change to 100% Spot Black, 50% Spot Black

-An Artwork that is 100% 115 U, 100% 3005 U, 50% 3005 U > Change to 100% Spot Black, 100% Spot Black, 50% Spot Black.

...And so forth - so every colour becomes Spot Black while also retaining the % information.

Is this something possible to do as a Script?

Hi.

Take a look at InkQuest from Astute Graphics:

With just one click you can make a color separation.

I make a quick video for you: InkQuest Video

I have no experience with spot color, so this is a shot in the dark. This should change all spot colors (but only spot colors) in a doc to black without affecting the tint. 

var spotz = app.activeDocument.spots;
for (var i = 0; i < spotz.length; i++) {
    var color1 = spotz[i].color;
    color1.cyan = 0; color1.yellow = 0; color1.magenta = 0; color1.black = 100;

}

Thanks. Just gave this to some of the guys here and they love it!

Thanks again.

As far as I understand your request, almost all (perhaps even all) requirements can be solved with Illustrator's native Recolour Art mechanisms (see Edit menu) or with the Merge Swatches command in the menu of the Swatches palette.
