Whilst it was in demand, I used to sell stained glass windows. Some with crystal bevels and glass etch film.
It was important to have the etch looking authentic alongside the Ledawork and colour-marbled films. Most of the etch films today just don’t look right, side-by-side. I am going back over 15+ years now, but the one I preferred using was an etch by Mactac, which has since been acquired by Avery. So the ranges may have changed over time. The marble and colour films that I used were not a sign industry brand of vinyl and had a 10+ year life and the Etch was something like 5-7 years which was a gripe of mine, to mix them. But as there wasn’t a colour stability concern as such and the film was sealed by lead, I used it regardless.
Back then, I remember Mactac also launched one of the first ranges of coloured etch and transparent colour-tinted films, so they appeared to be going in pretty heavily on decorative glass products.
Anyway, my point is that it might be worth requesting some colour swatch cards or swatches from the distributors to see if any suit your needs.
For me, the flat etch finish without an air-release adhesive or special effect is the best match you will get to the real thing. all these sparkle ranges doing the rounds, just do not look authentic, in my opinion.
Just for the record, I am not saying there aren’t others out there that are authentic-looking, better priced or have a longer life expectancy. I just mean back in the day when it was vital for me to get authentic-looking etch, Mactac ticked the boxes, back then.
