The G7 method is a new approach to press and/or proofing color calibration. In this two-part Webinar series, Don Hutcheson, inventor of the G7 method, provides a definitive step-by-step "how to" instructions for calibrating any proofing or printing system to the G7 specification.

• improve proof-to-press color matching
• reduce make-ready times
• simplify file exchange, and
• lower production costs.

Based on the ISO 12647-2 printing standard, G7 departs from traditional TVI-based calibration to achieve more consistent visual appearance in neutral gray tones with RIP curves alone. When used as part of a total color management approach, G7 extends the value of new technologies like CTP, ICC and digital proofing.

Topics to be covered in this 2-part series include:

• A review of the basic G7 concepts and terminology
• When and why you should (and shouldn’t) use G7
• Getting ready to calibrate a press or proofing system
• Making the first test proof or press run
• Measuring the P2P target
• Plotting NPDC curves via the free graph paper method
• Calculating curve corrections manually
• Using the automated IDEAlink™ Curve software
• Confirming results with a second proof or press run
• Using G7 calibration in an ICC workflow
• Why G7 is valuable even if you use DLPs
• G7 process control methods, tools, and aim points
• Validating a G7 proof or press sheet
• Dealing with metamerism and other issues
