Hi Darrell,
I have some scrap layout on non-premium HP transparencies that I can
send you to try transferring. Did you change the printer settings
to dark and max dpi when printing? I too noticed that most office
supply stores are only carrying the premium, and they usually come
in 50 packs at about a dollar each...
I've had good success with the non-premium HP inkjet
transparencies. I tried some Compusa last weekend, but am not
getting as good of a transfer. With HP, I usually only touch up
fills and accept minor pitting on traces. With the Compusa, I'd be
inclined to touch up some traces and that's too much work. I'll
keep working on my technique with those to see if I can get them to
work.
I'd like to try the premium inkjet transparencies. I can trade you
a few sheets of my transparencies. If they don't work for you, it
might be your printer.
I've had good transfers with an HP Laserjet 8100DN and a Lexmark
Optra E+ (with refilled toner cart).
The Compusa printed very well and while I was transferring, I
noticed fewer pin holes in the fill areas. But, I was disappointed
when I peeled the transparency. Too much toner remained on the
transparency. I'll experiment with heat, pressure, and peeling temp
to see if that makes a difference.
Low toner adhesion on the transparency shouldn't be an issue as long
as it doesn't get rubbed off before you transfer. Low adhesion
seems like it would be beneficial... Unprinted areas could be a
printer/toner problem because I haven't had that problem with either
inkjet transparency I've tried. I also tried Phaser wax
transparencies; they worked better than laser transparencies, but
not as good as inkjet.
Regards,
Dennis
