Using Pantones instead of cmyk
I am working on an old PS file supplied by a customer. They need the colors to be pantones not CMYK. When I select the area I need to change and fill it with a pantone from the color book the resulting color is still a cmyk build. I have double checked by exporting it as a pdf and then looking at it with the out put preview option and the color is still a cmyk build and not a pantone. How do I fill a selection with a pantone color and have it stay a pantone and not a cmyk build. I am using Photoshop CC 2018 on a Mac.
