However staying below eight colors is generally a good practice to follow. This is because there are simply not enough screen-printing shops capable of handling more than eight screens. And those that can will often charge you liberally for their specialized services. So, for the sake of your own sanity and your printer's, keep your designs to eight colors or less and remember less is more – restrictions can often lead to great design breakthroughs. Using these limits and researching different printing techniques and effects will help to maximize your shirt's monetary and visual value.
