Okay, so let’s start a list of tags.
UV
Waterslide Decals
Hammered Stamp
Inkpad Stamped
Laser Cut/Engraved
Etched
Machine Engraved
Masked (would refer to designs where different colors are painted)
No ink film
Dry transfer
Michael W.
Silkscreen (don’t laugh, my wife still has, but cannot get the proprietary supplies for, a 4 x 5 inch silkscreen frame that was perfect for pedal designs…)
Hand painted / Inked
Vinyl wrap (early Dr. scientist is great example of this style)
please add more, let’s get a compact list (“other” would be fine, or just no tag, for really unusual approaches.
