It wouldn't matter if it was in CMYK or RGB - normally you would use RGB. (CMYK is required in process printing which is something you don't need right now.) For your one colour design you are using what is called a 'single spot colour', that is a single pure colour. You would print your design out in jet black onto an acetate and then use this to expose a screen. Where the acetate is black the emulsion will wash out making a stencil.
You make your colour by taking pale yellow ink and slowly adding drops of red. (Later you can buy an ink mixing system.) Search for 'screen exposure' on YouTube and look at all the related video's. The book that most people use at the beginning is Scott Fresener - 'How to Print T shirts for Fun and Profit' but I'm not sure if it's still available. Regards, Bruce.
