Beyond G7: Achieving True Print Accuracy with ChromaChecker

G7 and G7+ are valuable process control methodologies, but they fall short in one critical area: accuracy. Anyone who has thrown darts shot a gun, or aimed an arrow knows that accuracy is what truly matters at the end of the day. In the world of printing, the same principle applies.

Printing companies aim to achieve two key objectives:

1. Match Printing Devices to a Reference: Ensuring all devices produce output that matches a defined standard, such as GRACoL.

2. Achieve Consistency Across Devices: Ensuring all devices in the workflow produce consistent output that aligns with one another.

However, G7 and G7+ only promise a shared visual appearance—not quantifiable accuracy. For example, have you ever compared multiple G7-certified prints and wondered which one is most accurate? Or, more importantly, wanted to measure how different two or more G7-certified prints are? Unfortunately, G7 and G7+ do not provide answers to these critical questions.

Why a Print Quality Platform is Essential

This is where a robust Print Quality Platform, like ChromaChecker, becomes indispensable. While G7 serves as a foundational method to achieve a shared appearance, ChromaChecker goes further by addressing the unmet need for accuracy and quantification. It represents the logical and natural next step beyond G7.

Here are the key benefits ChromaChecker provides:

1. Quantify Accuracy to GRACoL Reference: Determine how close each printer is to the GRACoL reference. This allows for an objective evaluation of print quality.

2. Monitor Consistency Over Time: Track how consistent a printer is over time to know when updates are needed, such as re-calibrating the G7 curve (for conventional printing) or refreshing the ICC profile (for digital printing).

3. Compare Device-to-Device Accuracy: Assess how well multiple printers match one another. This includes comparisons like digital to conventional, proof to press, or one digital press to another.

These capabilities are crucial for every printing company. G7 is a valuable tool for establishing shared visual appearance on conventional presses, but it does little to ensure a precise color match. By investing in a Print Quality Platform, companies can achieve both the accuracy and consistency they need.
