Graphic Standard
Graphic technology standards establish the technical specifications and tolerances required for consistent color reproduction in commercial printing. ISO 12647 regulates the process parameters for offset, flexographic, and digital printing, ensuring that printed products match the approved customer proof. This standard defines the color values of the solid inks, the target dot gain curves, and the paper substrates allowed for compliant production.
It applies across the global supply chain, allowing brands to achieve brand color consistency regardless of where the packaging is printed.
Color Control
Color measurements on the printed sheets must be performed using spectrophotometers under standardized lighting conditions to verify compliance. ISO 12647 specifies the target coordinates in the CIELAB color space for primary and secondary colors, as well as the permitted deviation tolerances. By holding the press run to these strict limits, the printer prevents color drift between different batches of packaging.
This level of control reduces substrate waste and accelerates press set-up times.
Process Calibration
Substrate properties such as brightness and fluorescence must be categorized according to the standard to ensure accurate color targets. Paper mills must supply boards that conform to these specific printing substrate categories. Standardized substrates ensure that ink recipes perform predictably on the press.
