Anyone willing to etch some PCBs?

Hi Jonewoo,

I would add that a laser does not replicate accurately due to the way in which the laser printers work, one is liable to notice "bands" of distortion aligned down the printing process. Noticeable if one prints an image at 90deg to another and overlays them on paper.
This may cause an issue depends on requirements, but I would always go for an ink jet printing in photo mode using paper treated with highly absorbent seaweed.

Basis test is pick up image and if you can see the sun through the ink then............

Ive been using the borrowed lazerjet. Its giving much better results than anything i tried on an inkjet. I have been using special PCB paper for both printers and the lazerjet is quite old but its still doing a better job.

Ive also changed the developer/water ratio and started using the orange acid. these have helped improve the PCBs too
