Delivering Consistent and Vibrant Packaging Across All Substrates
At Korpack, we’ve made it our mission to master the art of packaging. We know how important it is for your products to stand out on the shelf. GCMI colors are the gold standard for flexographic printing onto corrugated substrates and with a wide range of color options, you can do more than just a plain black logo.
You might wonder, why GCMI colors? It’s simple: they are created specifically for corrugated packaging, which means the color swatches you see below are the various GCMI colors printed on actual corrugated linerboard material. In using these color swatches to pick colors, you can see what the end result will look like.
Why not use PMS colors? PMS colors are primarily used when printing on substrates with a pure white background or a substrate that will not distort the color. Corrugated being a porous substrate, the color of the linerboard whether it is Kraft (brown) or Oyster (off-white) alters the color you would expect on a more suitable substrate. Since the color of the linerboard can affect the end result, you will also notice slight changes in the color solely from different shades of linerboard. For example, a darker brown corrugated box will make the color appear darker than a lighter-colored box that may have more recycled content in it.
The best way to achieve the color you are looking for in the end product is by picking from the swatches below because this is what the color will look like on your corrugated box and will be the best way to match the PMS color you desire.
At Korpack, we’ve been around the block a few times. We don’t just know GCMI and PMS colors—we live and breathe them. Our team uses the latest technology to ensure your colors are as vibrant and precise as they need to be. Whether it’s a bold red or a delicate pastel, we’ve got you covered.
Have a specific shade in mind? No problem. We can create custom color matches, even for those hard-to-get hues. Metallics, fluorescents, you name it—we’ll make sure your packaging looks exactly how you imagined.
One of the biggest headaches in printed packaging is being “off brand”. GCMI colors mitigate that issue by getting closer to your PMS color than printing the PMS color itself. Every time your boxes roll off the line, they’ll have the same crisp, clear colors that you approved. No surprises.
GCMI colors are perfect for corrugated packaging, food and beverage containers, and e-commerce shipping boxes. Whether it’s a durable shipping carton or a fancy subscription box, these colors bring your packaging to life.
Flexographic printing on kraft and white porous substrates is where GCMI colors really show their strength. They offer unmatched clarity and vibrancy, ensuring your packaging stands out in all the right ways.

Every brand is unique, and your packaging should be too. We collaborate closely with you to create packaging that not only looks great, but also tells your brand’s story. GCMI colors are an integral part of that process.
