i dont think you can build the ink high enough on the Colorado. But it's really not for it.Hey good people, Last year I completed an analysis and recommendation assignment for a long-established safety & braille sign shop. After tests, conclusion was flatbed UV was only way to go. One in particular (no bias at all) the Mutoh XPJ661UH delivers great ADA braille in multi passes, clear or in colour. Only drawback is max bed size 483mm x 594mm, kinda B2. It's slow due to multi-passes but faster and better than indentations and beads. Mimaki JVs in multi-pass mode work well too. Colorado/UV Gel is a great system but for braille?
Back in the day id probably try it when we had less volume, But these days the dont have 2-3 hours of the day to mess about
What i found with ADA signs, is it's low volume. It's most popular on those Mutoh & Mimaki small flatbeds. Also DCS flatbeds...
Technically, Direct Color Systems has a patent on printing ADA signs, so you're suppose to use their machine. https://www.directcolorsystems.com/applications-2/ada-compliant-braille-sign-printers/
Although i've seen their print quality at the last tradeshow and wasn't impressed.
IF you had to do volume, you could get a faster machine like a Canon Arizona with double row of heads or even the 6170xts with white ink. Or swissQprint loaded with heads.
but you need volume for that.
