Re: QTR with MIS UT14 (PK & BO) rubs off?

2012-06-23 by jffelinik

I will see if I have the time during my summer leave in August, until then there's no way I will be able to dig into this. I started printing some months ago and I am not that familiar with everything, yet, but I have an IT/Computer background so with the tech stuff I'm quite a geek and savvy, but time is a constraint....

So for now the UPGPP ICC will be good enough, even though I do like the black only profile results better, though the "customer" (a friend, ie. non paying, I can't charge until I know what I am doing...), wants album prints and not framed prints, this will have to do.


Best,

Cheers,
J.F. Felinik
