Excalibur ColorPRO Series produces simulated Pantone colors using 11 ink colors (including black and white) and 5 booster colors. ColorPRO is a Pantone licensed system which means you will produce the most exact color. All of the colors have been mixed and test printed on T-shirt fabrics. ColorPRO has excellent opacity and is suitable for printing on lights and darks. Formulations are based on weight and are extremely easy to follow. Simply select a color from your Pantone Color Formula Guide and find the formula in the Colormate PRO Software. You need to mix only the quantity that the job requires. Colormate PRO Software is used for both ColorPRO and PCPRO Colour Mixing Systems. The software also contains color recipes for all stock Excalibur series colors and will also estimate the amount of ink required. Colormate PRO will also calculate any unit of measurement such as quarts, gallons, liters, kilograms or pounds.
