What is the difference between RGB and CMYK?
These are the two main color models. RGB and CMYK.
RGB stands for red, green, and blue and is compatible with screen viewing. RGB colors will appear brighter since they are formatted with the brightness of a computer screen to enhance these colors.
CMYK stands for cyan, magenta, yellow, and black. This is compatible with printing and this is the color mode that we print in. The richest black when printing with us will be 40,40,40,100.
The takeaway, create your artwork in CMYK so your file's colors will be accurate to the final print. RGB allows for very bright and vibrant colors while CMYK is a little duller, convert your color profile in your file to CMYK so you are not surprised by your printed transfer's colors!
Here is an example of the color conversion from RGB to CMYK.
