Understand the difference between RGB and CMYK
RGB stands for Red, Green, and Blue. It is used when images are displayed on electronic screens(computers, digital cameras, and so on).
CMYK stands for Cyan, Magenta, Yellow, and Black. It is the color scheme used for printing physical items.
Naturally, there is a small color change when RGB colors are converted into CMYK colors.
How to prevent unwanted surprises
Before printing, your print file will be converted into CMYK color mode, which could result in a slight difference between what you see on your screen and the actual printed product.
If your print file was created in RGB color mode, we recommend you use a design app such as Photoshop to convert it into CMYK color mode and preview the difference.
