What is the difference between RGB and CMYK color models?

RGB is an additive color model used for digital displays, where colors are created by emitting light. CMYK is a subtractive color model used for printing, where colors are created by absorbing light.

Why do converted colors sometimes look different?

RGB and CMYK have different color gamuts (ranges of colors they can reproduce). Some colors that exist in one model may not exist in the other, leading to slight variations.

Can I convert CMYK back to RGB?

Yes, we also provide a CMYK to RGB converter for the reverse conversion when you need to go from print back to digital specifications.

What are the valid ranges for RGB values?

Each RGB component (Red, Green, Blue) should be between 0 and 255, representing the intensity of that color channel.

Is this conversion mathematically accurate?

Yes, we use the standard RGB to CMYK conversion formulas that are widely accepted in the design and printing industry.

What does the K in CMYK stand for?

The K in CMYK stands for Key, which is black ink. It's used as a separate black channel to improve print quality and reduce ink usage.
