The mockups shown in the Design Studio are there to give you a general idea of how your finished product will look, but they are not a 100% precise representation of the final printed result.
Small differences in colors, proportions, and positioning can occur between the preview and the physical product. This is completely normal and something to keep in mind when finalizing your designs.
To make sure you're happy with the result before committing to larger orders, we strongly recommend placing a test order first.
This gives you the chance to see the physical product in hand, make any adjustments to your design, and perfect it before adding it to your store or ordering in bulk.
