Re: PCB etching

It's easier to remove the transferred imagine using acetone, which is what you would do after finishing the etching.
After [laser jet] printing on glossy magazine pages, etc. and having to transfer the image several times to get a complete transfer, I was never satisfied with the remaining copper because it always had pitting and sometimes narrow traces with a very fine break in the conductor (open circuit).
I found some fantastic materials on the internet that absolutely provides a perfect transfer the first time and additional materials that fills the teenie-tiny pores in the laser jet transfer and eliminates the pitting in the remaining copper.
Check out the materials at -
You can purchase packages of the individual materials (transfer paper, toner reactive foils [seals the transfer], and a white trf foil to apply a "silkscreen" looking image on the component side of the board to label component locations, etc. or they sell a kit with all the materials including several sheets of copper clad material, the kit is called PCB Fab-in-a-box.
The kit does not include etching chemicals.
