Re: [colorvision_group] BP and importing PS curves

2007-05-05 by Antonio Bayma Jr

Hi David and all,
Just to report the last experiments. My conclusion is that Epson R260/270 with dye inks (even with Epson ones) does produce shades with noticeable discontinuity and non-linearity on some glossy papers, at least on those four papers and with three different sets of ink I have tested. Epson R200 (maybe R220 neither) hadn't shown the same problem with those paper and dye ink combinations. Yesterday I purchased pigmented inks and after the very first attempt to print, all that distorced and clogged shadows were gone, although there were a bit of bronzing, not found on samples printed with those dye inks. Attempt to profile it gave me a perfect result. A whole new life.
So, what I would suggest is to avoid dye inks with those R260/270 (are they really the same printer?). The bronzing effect with the pigmented alternative is something undesirable, but it's the price to pay for not purchasing a more expensive printer (R800 or R1800) with glossy optimizer.
Wish I can help people with those information.
Best regards,
Antonio
Trying to beat a bad printer/ink/paper combination into submission
though profiling is not a very good choice; finding a printer/ink/paper
combination that performs well is a much better way to achieve good
results. Every so often I run up against someone just determined to
make some rather poor combination work by profiling it (almost always
to save money: on a low cost paper, on third party inks, or on an older
or low end printer). Inevitably they say they can get improvements, but
they still aren't satisified. They need to have some perspective about
this process: it isn't magic, it can make bad combinations better, and
good combinations excellent; but it can't necessarily make bad
combinations excellent.
