Hi 50 years ago I made etched plates using ferric chloride FeCl3 on brass ,using Letrasett. letters and numbers ..for really small numbers I used all the small print from the bottom of the letrasett sheets!! this was one I made for someone ...the types of brass and copper gave different textures I learnt this as I was an electronics engineer and also made PCB's Printed Circuit Boards.

I've used both the acid metod and the electro etch methods, much prefer the electro method since no nasty acids. Both ways used the blue transfer paper that were printed then ironed on. Both gave equivalent results, nice fine text, though you can't go too deep or it undercuts the mask. Was great for small plates with fine text. For larger and deeper, cnc worked better.
