Images are printed in full squares. Ink colours will not print to their respective shirt colours, allowing for a transparent background. This means a totally black background will not print on a black T-Shirt and white will not print on a white T-Shirt. *Not applicable to Grey T-Shirt. Please note that your design will not be generated with a transparent background. Kindly wash and iron your T-Shirt inside out. Although we pre-shrink our apparels, fully cotton fabrics can still inherently shrink by 4% to 6%. You can minimize this by washing the T-Shirts only in cold water and air drying it, or tumble dry on a low heat setting.
