Designers name starts to be almost as important investment as the design itself. This means that the Name is sometimes brutally forced into the design. This also creates contradiction to the designer. First option is to keep design clear and expect that a sticker will emerge and other one is to promote your own brand but possibly compromise the design into some extent.
Personally I don't like any kind of stickers, nor this kind of 'design features'. I'd rather keep the design clear and let it speak instead of milled letters..
In the picture you can see Origo light - designed by Eero Aarnio as you can clearly see..
