Why is there color difference?
1. The color difference from the photo on screen
RGB is additive and made up of light, where the more colors you combine the brighter and closer it gets to white. The less colors you combine the closer it gets to black. This explains why it's possible to get bright, neon colors in RGB. Your TV, computer and phone screens work this way.
Since RGB has a larger range of colors than printing ink, some RGB colors are difficult or impossible to match exactly.
In addition, due to variations in monitors and browsers, colors may appear different in print than they do on screen, and the colors on your screen may also be different from the colors we see on our screens.
That's explain why there is color difference from the photo on your screen.
2. The color difference from the ordinary sticker in your hand
The ordinary stickers in your hand are printed by inkjet printer with CMYK inks.
CMYK is subtractive and made up of ink. The more colors you combine the darker and closer it gets to black, and incoming light cannot reflect as much off of the substrate. So you can convert REB image to CMYK file, which can help to control color difference well.
However, our UV transfer labels are not simply printed by inkjet printers with CMYK ink, but made by screen printing. So it is totally different from the ordinary sticker in your hand.
If you only order 100 or 500 labels, we can only modulate the ink artificially, and the color difference is unavoidable.
