3.6 Details of quality adjustment items 3 3.6.15 About G7 Calibration In addition to the regular controller calibration, measure the accuracy and check the Gray Step (gray balance) measurement result as necessary. Based on the values for gray color standard state, execute the advanced controller calibration (G7) as necessary. The following two methods are available to perform G7 Calibration. - Manual adjustment by using Color Centro - Automatic adjustment by using the touch panel . Meaning and Purpose of Advanced Controller Calibration While the regular controller calibration adjusts the output density of C, M, Y, and K colors, the advanced controller calibration uses primary colors (C, M, Y, and K) as a one-dimensional curve and adjusts gray balance for enhanced color reproduction accuracy. Exact Color is the default setting in Color Centro. When Color Centro is set to Exact Color, G7 calibration cannot be added and used side-by-side. When you want to change Exact Color to G7 calibration, contact your service representative. . When to perform - Any time (If the accuracy measurement result presented a greater ΔCh value (saturation difference), etc. than the preferred value) . Precautions - To reproduce stable colors, make other image quality adjustments as necessary, such as when chang- ing screens or papers or when hue is important. For details, refer to page 3-3, page 3-4, and page 3-6. - If the advanced controller calibration (G7), page 3-3, page 3-4, or page 3-6 does not improve color sta- bility, creating a profile may resolve the problem. .
