ADA Compliant Braille Stickers

[Smoke_Jaguar]

Playing around with decent speed printable braille transfers that meet ADA compliance and can be done with a $3k printer. No flatbed needed, small foot printer using 3 dirt cheap XP600 heads. Nice thing is it lets me print huge gang sheets of the things where needed. Wondering if there is much of a market for such a thing, or it's monopolized already?

Managed to get heights up to 1mm and can do dot diameters as small as 1mm with .5mm height. Adhesive is more durable than some UV cured application systems, no special materials and ink-jettable UV epoxy that runs about $60/liter.

Still playing with compensation and alignment for printing on semi-spheres, would be cool to offer colored or even designs printed in the dots themselves in the future. Lots of maths tho.

braille transfers

Would this be like a transfer to apply braille that was preprinted? From my standpoint, where I can already engrave copy and drill braille, this is adding a step that may screw everything up if it's applied crooked.
If this could print direct to substrate, does it have clearance to print close to 1/32" raised copy? You can imagine most signs get letters then braille, so the regular seeing sign folks don't have to learn braille to know what sign is next in the stack.

My first thought was literally braille stickers, which I hate to burst your bubble, but that's old hat:

Alignment can be tricky without a line to work with; these are printed raised transfers that are generated and printed on demand as opposed to being applied one letter at a time. The only thing being added to the sign or whatever is the dots themselves without extra vinyl/tape/etc. Not a particularly new technology overall, but something that allows a lot of flexibility. We can also laser-cut the transfers afterwards for accurate indexing. Since most ADA signs used raised elements, wouldn't be hard to cut a sheet to index to those features for near perfect accuracy.

Just noticed the amazing listing says the hand label maker has a processor, a USB 2.0 port and can do 203DPI, impressive.

Ha, I didn't even read it, it also says it's thermal printing, but it's just a physical punch for vinyl tape.

Can you not also print the lettering? I'm really curious, as a braille and text printer 'should' be a game changing money printing machine, but as DCS has showed us, at least their machine is far from perfect.
Also curious how the adhesive works? Like, are you printing dots straight to 'exposed' double sided adhesive, and the dots are the only area that the adhesive releases when transfering?

Feel free to DM me for specs. It's pretty easy and don't want to give away the game to early.
But it can do lettering and whatever else.

Here we go, full raised sign stuff. Need to tweak the ink a bit to keep the creep at bay. Printed to a transfer and applied to wood, not printed directly.

so is this basically printing the braille as a UV-DTF transfer then?

Modified ink and adhesive, modded printer as well to get the height required. Asides from the higher head gap and extra heads (4 6 channel TX800 heads), messed with the bidirectional calculations to adjust to higher pass counts. Also had to stack some more UV lamps in.
