Sorry for the late answer;
Best way is to replace the label before you shoot, it's faster and better :)
But there is way to change the label afterwards.
Create a new blank layer.
Pick the stamp tool and set the mode to "lighten".
Keep an eye on the light value of the label and try to choose an appropriate source for the stamp tool.
Use it on the text or pic. "lighten" mode will keep the light areas untouched and will effect only dark parts of the image.
Use a hard brush to prevent loss of texture.
You will need some empty space to use this technique.
Change the label and save your lifetime, quality :)) any textured white paper will work, you change the paper's color later.
