If you’ve ever been shocked by how dull your printed design looks compared to what you saw on screen, you’re not alone. The culprit is often RGB.
Most people don’t realize there are different color systems for digital vs. print. One of the most common misunderstandings? Using RGB for a design that’s meant to be printed.
Let’s clear that up.
What Is RGB?
RGB stands for Red, Green, and Blue – the colors of light used to create images on screens. Your phone, computer, tablet, and TV all use RGB to display color.
Here’s how it works:
-
RGB is an additive color model: the more light you add, the brighter the color.
-
All three colors at full intensity = white.
-
No light at all = black.
-
RGB produces a wide, vibrant range of colors—including intense neons and glowing blues—that simply can’t be printed with ink.
That’s great for digital. But printing? Not so much.
Why RGB Doesn’t Belong in Print
Printers don’t use light – they use ink. And that requires a completely different color system: CMYK (Cyan, Magenta, Yellow, Black).
If you try to print an RGB file as-is:
-
Colors can shift dramatically.
-
Bright hues like electric blue or neon green may come out dull or flat.
-
Your design may not look anything like what you approved on screen.
Case in Point:
I once showed a client side-by-side versions of her wedding invitation: one in RGB (bright and punchy) and one converted to CMYK (softer and more muted).
When she brought the CMYK file to her printer, he confirmed exactly what I’d told her – that’s how I help avoid surprises.
When to Use RGB
Use RGB when your final design is for:
-
Websites
-
Social media posts
-
Digital ads or banners
-
Mobile apps
-
On-screen presentations
Basically: if it’s staying on a screen, RGB is perfect.
But if it’s going to the printer? You’ll want to switch gears.
What to Remember When Sending a Job to Print
-
Always convert RGB files to CMYK before printing.
-
Don’t rely on your printer to “fix” the color for you – they often won’t.
-
Work with a designer who understands the difference and can prep your files correctly.
