The Color Guide XI presents a collection of 46 colors printed on both white top and natural kraft substrates. This edition includes all 42 inks featured in the previous Edition X Standard Guide, along with four newly added inks. While each color has been rigorously tested for consistency and tolerance throughout the print run, advancements in printing technology and ink formulations may result in slight variations compared to past editions.

Previously known as the Glass Container Manufacturers Institute (GCMI), the Glass Packaging Institute (GPI) proudly introduces the Edition XI Standard Flexo Color Guide for Printing Inks on Corrugated. For over 70 years, this guide has been a vital reference for the paper converting industry, ensuring accuracy in color selection and consistency. This latest edition has been carefully updated to align with modern substrates and materials widely used in today’s industry.

The Edition XI Guide showcases 46 of the most frequently used colors, presented on both white top and natural kraft stock, offering a clear representation of how they appear when printed using flexographic processes. It is important to remember that color perception can vary due to factors such as substrate type, ink metering systems, and ink film thickness. Accurate color assessment requires proper lighting conditions. To maintain precision, spectrophotometric measurements have been utilized to verify colors and ensure consistency throughout the print process.

GPI recommends replacing the guide every nine to twelve months, depending on usage, as prolonged exposure to light may cause color fading over time. This essential color guide is an invaluable resource for packaging designers, printers, and brand managers, aiding in accurate color communication and consistency across print jobs. By offering this updated edition, GPI reaffirms its dedication to quality, innovation, and the ongoing advancement of the packaging industry.
