How to use pantone-colors in photoshop?

[moochmaster]

Hi,

at the moment I'm trying to convert an image from CMYK-modus into a TRITONE-color image.

Using 3 layers and each layer has to have one Pantone-color... I did tried this, but instead of giving it a single pantone everything is mixed-up into one color.

So, after trying this I seperated all 3 layers into 3 seperated psd-files > giving each file a monotone-color, putting it back together into a new psd-file (tritone)... but still the same problem.

Can somebody give me an idea how to handle/solve this issue?

Thx,
Belgium boy.

Channels is where color is stored. Add 3 channels each with a different Pantone.

OK. And what about the orginal CMYK channels? Leave them or do I have to delete them?

either. Mode--Multichannel is what I'd save the image as. And I would trash all your empty channels.

I done this using the multichannel mode, selecting the spot colors for the channels, deleting in the respective layers what should show on the other layers, save it as an eps DCS 2.0, click the spot colors button, give it a tif 8 bits preview, dcs single file with composite color, binary encoding, include transfer function.
Thats's it.
If you make changes to the file you must repeat the process, just saving doesn't work

...here is a great use of vector masks and monotone use for spot colour channels, this enables crisp curves on output, saving as a phtoshop pdf...

...layer effects can be added to as in this example...
