Just bring up to date on a very strange dream.
It looks like Dye based ink's may hold up to std etching solution! Ran a test using a small square of paper with black text and drop it into my normal etch tray with an amount of etch and did my normal actions that I do to a pc board. No problems after leaving it in for 40 minuts or twice the time I normaly use.
The paper was heavly stained and basicaly now a yellow tranparancey but the letter held! :) I was able to scrape some but where I did normal thing to it, the text held up very well. Was also able to wash off the solution like I normaly do.
Now need to get some ink on a square of PC marterial and give this a try. Nothing major but since my ink jet uses a J-Path need to think on this. proabbly just hold it steady and print a short pattern on it. If this will work and I can get the rest of the pipeline with a strate through printer then I can crank out board as faster than it would take me to dream them up!
I know regular sign grade vinyl holds up very well to etching solution also.
Wish they had copper particle ink cart for printers. ;)
