Brian, Steve, Gareth,
Yippee! UT2 1290 using 1280 drivers is up and running I'm so
pleased. I managed to get a lovely, moody print using the carbon
curve last night as well. Thanks, Steve.
Thank you too, Brian, for your comprehensive advice I suspect this
will interest many list members. I have kept a copy of what you have
posted, but which I did not see until this morning at work. I did
not try the other printers but will do so tonight. Assuming they are
all working I shall probably leave well alone until the Gods do me
down again. (Is this because I live in Greece and can see Olympus on
a clear day from my lounge!)
From Saturday I'll be on leave in Blighty until after Easter but,
after that, if Paul wants info on where the jumps are in Pettit's
step wedges with my setup, I will try to document and post them, but
I don't have densitometer. Whether or not these will mater in real
images I don't know but, in some cases, I think I would want to open
up in the 8 or so steps leading up to Dmax.
Awhile back I installed a PCI card with USB 2. In real life, will
using this enable materially faster printing than using the USB 1.1.
socket to which the printers are currently connected?
Thanks again for all your help.
Colin
