I guess that is true.. but

I must admit I never had a problem with undercutting, even when using
dual 12" tubes 4" away.. but then I don't do really fine traces..

Nowadays I almost exclusively use toner transfer and find it quicker,
easier, cheaper and more reliable.

The only time I don't use toner transfer is when milling.

I grind LEDs for a completely different application, for which it
works really well.
