Scanavo only talks about 3 finishes, from Scanavo themselves:
"The choice of varnish applied will have a dramatic effect on colours. A gloss finish brings out brighter colours, and gives blacker blacks. Conversely a matte finish tends to create a subtler, more muted palette. Not only does the varnish dramatically affect the intensity of the colours, but it can have an impact on the tactile feel of the final SteelBook® product. Matt varnished SteelBook® cases for instance can feel wonderfully silky and sensual to the touch. Partial varnish options are also available, meaning, for instance, that a SteelBook® case that is mostly a matt finish could have selected elements given a gloss finish, which will highlight these further. Lastly, varnish techniques can be creatively used to apply a texture to the final design."
So gloss, matte varnish and matte.
