Is there any chance to have the logo 100% opacity - I want to have the scale of the logo same and apply it on different box designs (different scale) - thank you!
decals will respect an alpha channel to mask out all but the logo. You should then be able to run the decal at 100% opacity with the background dropped out.
use a tiff file or a png with an alpha channel.
So how do you make a .png in photoshop that can export alpha channel? Does not seem to allow that in .png format even if you have an alpha mask in original file.
