We love seeing the incredible artwork you submit for your custom stickers and packaging! Lately, we’ve seen a massive surge in mind-blowing, AI-generated designs. While these look spectacular on your screen, translating them to a physical, printed product requires a quick lesson in how color and cutting work on printed media.
If you want your products to look exactly how you envisioned it, this guide is important.
Part 1: The Color Clash (RGB vs. CMYK)
The biggest hurdle in printing is the transition from a digital screen to physical ink. This comes down to two different color profiles: RGB and CMYK.
-
RGB (Red, Green, Blue): This is how digital screens (your phone, monitor, and TV) create color. They use light. By mixing red, green, and blue light at different intensities, screens can create millions of vibrant, glowing colors—including pure, bright white. All AI-generated art is created in RGB.
-
CMYK (Cyan, Magenta, Yellow, Key/Black): This is how commercial printers create color. We use ink. By layering these four ink colors on top of each other, we create your image. Because ink absorbs light rather than emitting it, CMYK cannot reproduce the ultra-bright, neon, or glowing colors you see on a screen.
What Happens When You Print RGB?
If you submit an RGB file (like a standard AI image), our printing software must convert it to CMYK before it hits the presses. When this happens, the colors will often shift, look less vibrant, or appear slightly "muddy" compared to your screen.
Take a look at the landscape below to see how a vibrant RGB sky dulls when converted to CMYK ink:

Part 2: Cutting, Bleed, and Safe Zones
Once your colors are sorted, we have to physically cut your stickers and labels. High-speed industrial cutters are incredibly accurate, but there is always a tiny, microscopic margin of natural shift during the printing and cutting process.
Because of this, we need to talk about Bleed and Safe Zones.
The Problem with AI Artwork
AI image generators are great at making art, but they don't understand commercial printing. They rarely add a "Bleed" (extra background color) and often put important text or focal points right up against the edge of the image. If we cut that as-is, your text might get snipped!
Round Edges and Corners
If you are ordering circle stickers or labels with rounded corners, the safe zone becomes even more critical. You cannot put straight text across the absolute bottom edge of a circle, or it will get chopped off by the curve.
Still Confused? Use this Guide ⚠️
To make sure your stickers and packaging come out perfectly every single time, just follow this one simple rule when setting up your files:
Keep all symbols and text at least 3mm away from the edges, and allow extra room for round edges if your packaging or label has them. By leaving this "safe zone" buffer, you guarantee nothing important gets trimmed off.
For Pro Designers: If you are building your files in Illustrator or Photoshop, please set up a 3mm Bleed Area (extending your background color/pattern 3mm past the cut line) and ensure your document color mode is set to CMYK.
