First of all, we use the ISO 12647-7 standard for the color management of the digital proof. This will make sure that original “benchmark” colors are correct. Then we have CIP-3 ink management system to ensure that color data in our prepress computers accurately transmitted to our printing presses, through the computer-controlled ink pipes. Finally, we have the X-Rite meters to measure the color-bar data on the printed sheets, another steps of quality control to ensure the color consistency.
