The plastic is polished black, the logo and text is reflective silver grey. I’m interested in replacing with a custom made cover, but I don’t know the process that was used to achieve this. I have found out that they most probably used laser etching for my iPod, but I can’t find anything on this. Thanks.
Update: I found an Ebay listing with the logo half scratched off, confirming my assumption of it being somehow printed on. I still don’t know how though, haha.
I found that foil transfer like stamping or printing is more likely to be the method they used. Screen print metallic ink is either too flaky or too shimmery, not reflective smooth.
