We operate to the ISO 12647-2 standard.
To ensure consistency, we have quality control 'colour champions' who constantly measure and record any fluctuations with our presses, paper stocks and other environmental / technical factors that can affect colour consistency.
In addition, our presses use closed loop colour management systems. Rather than relying on densities alone, the spectrophotometer automatically reads the printed sheet and collects an array of quality control colorimetric parameters including delta E, slurring / doubling, dot gain values, and trapping. Any fluctuations in these values are then automatically corrected throughout the print run to maintain colour accuracy.
In spite of this, there will inevitably be occasional colour variations. This is inherent in the print process, as different stocks, temperatures, and presses affect how the finished colour looks. However, you can be confident we are doing everything we can to perfectly reproduce your colours.
