Sometimes when we turn the UV Printed acrylic light box, the logo color will be changed and make the logo color totally different. The client will say: "oh, that's not what I want!"
Why will this happen? When we turn on the light box, the bright white light shine through the dark color logo, will illuminate it and turn it to a light color. Only the brighted color part will keep a similar color. So this problem will happen if your logo contain a dark color.
We have made one light box with "Dark Green" background. However, when we turn on the light, the background turns to a sky blue color, which is a totally different color. That realy strange.
After investiagte, we found this "Dark Green" color is actually a "Blue" color. That's why it will looks "blue" when the light is turned on.
I also attach some other samples below. Some color looks like a dark gray, but actually it's a "dark blue" color. The bright white light will show it's true color.
So my dear clients, Please understand that it's not a product quality issue. It's a normal case.
