You can learn more about indexed, process, spot, and simulated color separations in other screen printing articles on BrightHub. You can also learn more from my book Photoshop 7.0 for Screen Printers and Photoshop CS3 for Screen Printers. Both can be purchased from www.wordware.com.
Learning to color separate artwork will put you one step ahead of the competition, and help you gain a bigger foothold in the screen printing community and client base. Good luck and happy printing!
