Has anyone here used Positive Photo Resist for etching?
I want to use a technique like this to make small decorative details, but I can't find Positiv 20 in the US.
I did find PC197 from http://www.injectorall.com/photoresist.htm but it's very expensive.
I also looked into toner transfer paper but that's not cheap either and I don't know if it works with ink jet printers.
Is there another liquid or spray that would work as shown in the YouTube video?
Thanks
Have you taken a look at Micro Mark etch kit?

Yes. It's $139 USD. It's ridiculously expensive and with the technique in the video you don't need the laminating machine.
Apparently you didn’t look further down the page. Isn’t this what you are looking for?

Thanks but that requires a laminating machine, which I do not have.
Might work just to put it under a sheet of glass rather than laminating. I guess it's worth a try.
I just re-watched Luke Towan's video for the Micro Mark stuff, and the video that I posted.
One big difference is that the Micro Mark method requires that you start with a negative image, so I would have to see how to convert my images to negative. The other process starts with a positive image, which is easier.
I also want to use the sodium hydroxide / ferric chloride method rather than the hydrochloric acid method because the chemicals are less noxious.
I'm going to have to look into this further. There may be a way to combine the two techniques. Thanks for the info.
