If your order doesn't match the digital mockup you approved, you can absolutely return the shirts and ask for a reprint. Obviously, that's something neither of us wants and we work very hard to ensure you get exactly what you're expecting.
Also remember, water-based and discharge printing is more of an artistic process and craft than the average screen print. With water-based and discharge inks, a little color variation is to be expected. If color matching is of the utmost importance on your order, we recommend using our Bold ink.
