Re: Light scatter or something.
Wendy, do you strip the etch resist before or after drilling?
Might be interesting to experiment with both conditions and see if it makes any difference.
I always (used to) drill before removing the etch resist as the higher contrast made it easier for me.
Varifocals and bifocals don't agree with me, so it is multiple glasses for reading or the computer. At this stage my distance sight is fine (ish).
