A Case for G7 Printing in Packaging
Gray Balance and G7® are two terms that are hardly new to the printing industry. Gray balancing your process is a concept we have accepted for decades as a logical step towards process control and color management, and yet still today it is not widely practiced. In essence, gray balance on press is simply calibrating the printing process similar to what we did for scanners and analog film photography in days past.
So the question we might ask ourselves is, "Why wouldn't you want to calibrate your printing press?" We calibrate all types of devices in all facets of the production process. In fact, if we step back from the daily grind of our jobs, we can cite instances where we calibrate instruments we use in our non-professional lives, too. Two obvious examples are our automobiles and musical instruments. Why do we do this? What is the benefit of calibrating a proofer or a guitar or a car? What is the relevance?
Calibration has a two-fold benefit. First, it brings a device into a known state, often one defined by standards that direct us to a commonly agreed state of order. We tune a guitar to ensure the sound is pleasing. But lets take it a step further; the real benefit is that by knowing how the guitar should sound and will react to our finger placement and strumming of the strings, we can then combine sound combinations to compose something even more pleasing than the singular sounds we have calibrated. Secondly, calibration can help extend the life of our process (or instrument). In the case of your car, it is commonly understood we should go in for regular tune-ups and oil changes. Again, the initial purpose is to bring the car back to a known state of order, to get it back into spec as it were. But I think we can all agree that there is an added benefit of improving the longevity or extending the life of the car as well.
