CMYK vs RGB Artwork in Customizer Tool

The customizer is an easy way to design custom products on any device! But it is an RGB tool, and it is important to only upload RGB assets to it. We take a look at the color shift that CMYK files sometimes have when using them in an RGB environment and advise to only use RGB assets when designing custom buttons, fridge magnets and more in our free online customizer tool.

The free customizer tool on is great, but it's important to use RGB assets ONLY- meaning your pictures or artwork or logo files. The reason being is that the tool itself is an RGB tool, then the image is sent to our team who converts it to CMYK before printing. If you put CMYK images into our RGB tool they will then be converted one more time which causes compounding color problems. Let's take a look at what happens when you add a CMYK vs and RGB image to the tool. Here's a man playing baseball in CMYK. Now let's add the RGB version. By going to the Layers panel, I can see my two versions here. The RGB version is on top. Now when I drag the RGB version under the CMYK version, I'll see the CMYK version appear on top, and you'll see the color difference. Pay attention to the red tones in the man's skin, and the blue tones in his jersey, and the general darkness and saturation of the background. As you can see, everything is more desaturated, it's also a bit lighter. I'll bring the RGB version back up to the top. This looks more like we expect. Now if we submit the CMYK version, it will then be converted one more time to CMYK and undergo another color shift. So it's important to use RGB assets so there's the least amount of processing in between your design and the final printed product.
