Question having trouble with color seps

I have no clue how to do color seperations..
I have the proper programs on my pc but every time someone instructs me how to do half tones color seps and cymk they move to fast.
I need to be treated like a three year old and talked through it step by step.
I hope i'm not asking for to much..
Thank you
Dean

Dean...It may be hard to talk you through without knowing what type of printer and programs you have.
For instance: A post script laser printer will do the half-tone separations for you. Just go into the printers properties and select "color separation". It will spit out cmyk if that is what you want, or it will allow you to choose "spot colors" depending on your artwork and how you colored it in your program. You will also need to change the printers "dpi" and "lpi".
Your dpi settings should be set at 150 to 300. Anymore than that and you won't be able to burn them on a screen or print ink through them. Start with 150. The lines should be from 55 to 85. Most screen printers use 55 or 65 lines. 85 and up will allow to-little of a space between your half-tone dots and the ink will migrate or squash out and touch, leaving you with a muddy looking print.
Ink-Jet printers can do half-tones, although you will need to buy a "Rip" program to use with it. The rip software will let the printer print half-tones like a laser. You will also need special inks and special films to hold the ink and it can get costly but worth it if you already have that type of printer.
If your going to be doing half-tones, you better have a good exposure unit to burn the fine details.

I hope this helps, but more info would be helpful in answering your questions.
