I've added my UV texture, and I can see white pixelated borders around my red text. What's causing this? also below are the nodes I'm using, The text is supposedly going onto a screen surface. which isn't so realistic, any ideas what other nodes I can use to give it some screen surface feeling? I've seen some internet suggestions which are overkill over 10 nodes to get what's meant to be a realistic glass reflection. But I'd like a bit more minimal node composition if it's possible to get a nice result.

It's cause by your reference image, which is an png image I guess?

PNG(Portable Network Graphic) is not just a simple algorithm but an image storage solutions bucket. There are two main way to implement the thing "Transparency". And you might choose the simpler one:

enter image description here

If I use PNG-8 bit(paletted method) I will got the strange White border. That is actually coming from matte color since paletted method only allow one transparency value instead an alpha channel. When I choose PNG-24 bit(true color with alpha) we get a better image without border. enter image description here

So you need to redo that image to make the border show as an actual color. Or you can also use your image as alpha material socket input to reduce the white border effect.

    $\begingroup$ Ah... my image is made from Photoshop if you want to know. I am pretty sure GIMP got the same option to deal with saving PNG. $\endgroup$

  • $\begingroup$ Found a great solution, in the node editor: Change from Linear to Closest in your Image-Node, and it works perfect. $\endgroup$

  • $\begingroup$ @blenderbreath great idea, Blender use interpolation between those non-opaque color (which should be white as default?), you might want to upscale your png file if you want a smooth edge and no white border. Also you can answer your own question, that is a good practice $\endgroup$
