Hi guys,
Firstly, for a person brought up on metric, what is a 'mil'??
Secondly, I believe my hp 1022 is also a 1200dpi native resolution
what sort of minimum trace widths should I really expect to reliably
obtain?
Third, photo paper consists of good quality paper coated
in "something". Soaking seems to remove this coating where toner is
adhered (copper -> toner bond stronger than toner -> coating -> paper)
What would people comment on problems they have observed with photo
paper TT?
regards, PK
