I dont know in which place goes this my question. So I put it in offtopic.
Anybody knows for specialized printer for printing mask for PCB etching for making prototype?
If exist specialized printer to print "Happy birthday" on birthday cake, then maybe exist also this.
Hapy printing to all

There are plenty of specialist printers that will produce prototypes for you but they are expensive: duckduckgo.com/?q=pcb+fabrication+services.

Hi not sure but create the design and save as SVG file then you can use software for a etching type printer
I have a 3D printer and I do my designs the out put them in svg and use Tinkercad for creating the 3D code for my printer
Yes, I saw this. On this page, the PCB picture is transfered to PCB via film.
But i believe there is more direct way - via some type of printer to print direct to copper foil on PCB.
Then comes etching of PCB with solution of ferrum chloride in the water for exmple.
But yes, direct transfer picture from computer to PCB, without film.
And yes, I expected very high price of this printer, if exist.
Is this because you're making one PCB or making hundreds?Quote:

No, but most people would print onto acetate and then use a photo sensitive plate to etch their board, or even just draw it using transfers/etch resistant pen. It's been over 30 years since I did one so I would imagine this is simple to do with tons of examples on google about how to do this simply.Quote:

I wish to use some automatic. Automatic transfer from computer file to PCB.
It took me 30 seconds to find this.Quote:

things have moved on a bit since the days of [john] linsey hood - some things stay the same ;)
Some people are still using valves for their amplifiers, so the good old days are still here!Quote:

you can't really see the valves glow in the picture, EL84's in a modern 'leak' configuration are not like the old KT66s in class A - and the 'smart' phone has removed the 'unwanted' light...

Very strange. I thing, any plotter armed with waterproof felt-tip pen can make this job. Or not?
Then trick with iron. Ironinig is not my favorite sport, but there is no other option, except manualy writing on laminated vitroplast.

But the label says "Develeper", you know. And a little bit right, another bottle with label "Fixer". Inside is Cognac, of horse.
it's course not horse, unless of course, it's white horse, but that of course, is not cognac, it's whisky
sorry, my sense of humour...
watercolors by the way... no turps or white spirit :D
And another by the way.
I recommend Pleterski natural juniper. It is made by monks from the Pleterje Carthusian Monastery In Slovenia. It is an excellent natural disinfectant. For both outdoor and indoor use.
gin up eh :)
