RGB vs. CMYK

From Screen to Paper: Get Color Right Every Time

When preparing artwork for custom print products, one of the most important — and often overlooked — considerations is color mode. Understanding the difference between RGB and CMYK can mean the difference between vibrant, accurate prints and disappointing results. Here's what you need to know to ensure your designs look just as good on paper as they do on screen.

What is RGB?

RGB stands for Red, Green, Blue — the primary colors of light. This color mode is used for digital displays like computer monitors, smartphones, and TVs. RGB colors are created by blending light, which allows for a wide range of vibrant hues and brightness.

Best for: Digital artwork, web graphics, social media images

Not ideal for: Printed materials

What is CMYK?

CMYK stands for Cyan, Magenta, Yellow, and Key (Black) — the primary colors used in printing. Unlike RGB, CMYK is a subtractive color model, meaning colors are created by subtracting light reflected off the paper. This mode is specifically designed for physical printing.

Best for: Brochures, folders, business cards, packaging, and other printed products

Not ideal for: Digital-only designs

Why the Difference Matters

When artwork created in RGB is printed using CMYK, colors can shift — sometimes dramatically. Bright neon tones, deep blues, and vivid reds may appear duller or slightly off. This happens because RGB can produce colors that CMYK simply can't replicate due to its more limited gamut.

How to Prepare Your Artwork for Print

To ensure your custom print products look their best, follow these tips before submitting your artwork:

• Convert to CMYK: Always convert your files to CMYK before submitting. Most design software like Adobe Illustrator, Photoshop, and InDesign allow you to switch color modes easily.

• Use High-Resolution Images: Aim for at least 300 DPI (dots per inch) to ensure crisp, professional-quality prints.

• Check Your Colors: Some colors may look different after conversion. Use CMYK-safe swatches or consult with your print provider if you're unsure.

• Embed Fonts and Images: Make sure all fonts are outlined and images are embedded to avoid missing elements during printing.

• Request a Proof: If color accuracy is critical, ask for a printed proof before final production.

Final Thoughts

Color mode might seem like a small detail, but it plays a big role in the final look of your printed materials. By designing in CMYK and following best practices, you’ll ensure your custom folders and other products from FolderWorks come out looking exactly as you envisioned.
