COLOR MANAGEMENT SYSTEM, INK-CONTROL, DEVICE, PRINTER, AND PRINTING METHOD

摘要

A color measuring unit (22) measures color tone of an image printed on a test sheet. An arithmetic unit (12) compares color tone set based on print production format (PPF) data with the color tone measured by the color measuring unit (22) to set a color-adjustment amount. An operator selects an ink key zone for color adjustment while viewing the image using an operating unit (23), and sets a corrected color-adjustment amount for the ink key zone. Based on the color-adjustment amount and the corrected color-adjustment amount, an ink-supply amount is adjusted for the ink key zone.
