Our printers are calibrated accurately to print right colors. Our products are printed RGB, and we will make every effort to match the color of your design. In rare cases, some colors might have some variation. This will not be considered production error. We will not issue refunds, nor accept returns for misunderstandings due to color, depth, or tone. We are not responsible for differences, either real or perceived, between the appearance of the product on your screen and the final printed piece. We will address this situation on a case-by-case basis. Please make sure to put special instructions if you are very specific on acertain color.
