Create G7 calibration curves with an external tool Create G7 calibration curves with an external tool PRISMAsync supports the use of calibration curves created by an external tool, for example CHROMiX Curve3 ™. PRISMAsync uses media families to indicate which output profiles and calibration curves must be applied to a media. Hence, the creation of a new media family with the factory default G7 output profiles is part of this procedure. (See Media Families on page 29 and Media family calibration on page 170) Before you begin • Enable G7 support in the Settings Editor. (See Settings Editor settings and information on page 320). • A file with a chart intended for G7 calibration, for example the P2P25 calibration chart. Procedure 1. Calibrate the printer. Calibrate the printer on page 173 (See ) IMPORTANT You must always perform a printer calibration before you continue with this procedure. 2. Create a G7 media family in the Settings Editor. Settings Editor settings and information on page 320 (See ) 1. Open the Settings Editor. 2. Create a new G7 media family. 3. Create a new media for the G7 media family. 3. Print the G7 measurement chart via an automated workflow. Set up automated workflows on page 67 (See ) 1. Create a new automated workflow. 2. Select the media on which the measurement chart will be printed. 3. At [Measurement chart printing] select [G7 calibration] to print without color management. 4. Print the G7 measurement chart via the G7 automated workflow. 4. Measure the calibration chart. 1. Measure the chart, for example with an X-Rite ™ device. 2. Calculate the calibration curves with the external tool. 5. Import the calculated G7 calibration curves to the G7 media family in the Settings Editor. After you finish You can only disable G7 support in the Settings Editor when all G7 media families are removed. 256 Chapter 11 - Help imagePRESS C800 Series
