Question about 4 Color Process

Hi, I want to know more about how the 4 Color process works because I'm an Artist and one of the things I offer my clients is production ready material. I've been getting people who want some pretty vibrant designs done in a manner that's better done in photoshop rather than illustrator.

I know how to do the separations and how to switch it into half tones, but I'm not too sure about weather or not all you guys use is 4 screens to accomplish EVERY color no matter how many there are or if it's just 4 colors but sometimes you have to do an extra screen or two and if so when and how do you determine that and address it? What are the limitations of this process?

if I had a design with 20 different colors all in varying hues and intensities would this process be able to do it in just 4 screens? I just want to make sure I understand it before I go offering and suggesting it to my clients. I know how much of a headache it is for people to give you a 72dpi camera phone JPEG expecting a miracle. So I just create the different formats for each medium that applies to them and inform them on what they're for so when they come to you guys they can just give you pdf files of the separations or .ai/.psd file of the separated version and you can rock and roll from there without a day and a half of prep work they're NOT going to want to pay for. Just want to make sure I'm giving them the right thing. Thanks in advance :)

I've only ever used 4 color process as a stand alone. You can use spot colors but I imagine that would be best for a text above or underneath the image. The beauty of 4 color process is the ability to get those 20 colors without having to use 20 screens. I know some people use a white underbase and print 4 color process on colored shirts, but I've only used 4 color process on white shirts.
You'll usually end up with 5-6 screens depending on the art and garment color. CMYK, Underbase if needed (like Carguy25 I only do 4cp on whites so usually don't have one).

Lets say you have a lot of 100% black... say for the type, move that to a spot channel. Removing the 100% blacks from the process black channel will allow the press operator to adjust the process black with out effecting the opacity of the type.

Or if you have type and part is 100% cyan and part is 100% black you "could" move both to spot channels assuming there is a lot of cyan in the design. It all depends on the art.
