Screen printed t-shirts are most cost effective if you do a quantity of 12. The next price break is at a quantity of 24. If you only need a few printed shirts, then digital printing will be the most cost effective. Screen printing is priced on how many colors are being printed and how many locations on the shirt. Digital printing is a dye process and the shirt is put through a machine so there are no screen charges and it isn’t priced on how many colors are being printed. Call us about artwork requirements.
