how to make a well-defined, sharp and contrasted material?

Hi Everybody!

I was playing around with the widget component inside a texture that can be used with materials.
My widget is a web page, but when it is in the material, lit or unlit, in base colour or in emissive it looks too bury.

Here is how I see the widget with the UI (not inside a material):

And here is the same widget inside a bluprint, using it as a texture inside a material:

This is the component and the material automatically assigned:

And the material looks like this, but i try many other variations like directly on emissive in an unlit material, but the result is the same:

Hope you guys have any idea to try here, i want it to be crisp well-defined as possible to look like the first image as possible.
