cmyk with a spot color? 2

[raven07]

I have completed a project in illustrator 9, the project is using black and a spot color of blue. I made sure to pick a un-coated pantone color to ensure quality printing. My problem is, I have two color choices for the document setup, RGB or CMYK. I chose CMYK, but will that inhibit my spot color job, since now it becomes a four color job?
Thanks, E.R.

As long as you define the blue as a spot color, then CMYK is the right choice. Just be careful with placed images, though, and make sure you link them rather than embed, otherwise they'll take on the color mode of the document.

CMYK is correct, make sure your spot color name is spelled the same in both Illustrator and Photoshop, same color break as well. Do link the images do not embed your image, it will convert to process and will cause problems once your file gets to your printer.

When you send your file to your printer be sure to send them
the files that you placed in Illustrator. I worked on many jobs where the client will send the Illustrator file but forget to send the linked images they placed.

The PMS you choose really doesnt matter cause it all comes out as black and transparent anyway on the film. The guy running the press can put whatever color of ink he wants through it. My point is it wouldn't matter if you named it "my left foot". The difference between coated and uncoated is that one has a gloss finish and the other a matte finish. Anytime you are using spot its a good idea to go CMYK. It wont make a difference on your spot colors but it will affect the black plate which is where I pull off most of my tricks. Since CMYK has a natural black plate in it, any greyscale images you place will automatically come out correctly separated onto the blac(K) of the (C)(Y)(M)(K) process plates. So simply supressing the output of the Cyan, Magenta and Yellow plates would allow your Black plate to separate correctly (without having to make a black spot color) as well as the rest of your spot colors.
