For individuals that are trained in the science of color, the definition of
the word is well understood. Having the marketing department of printer
company redefine or misuse the word doesn't help anyone. On one hand CDT's
use of quotes was quite proper, on the other hand, it might have been more
beneficial, to those without his experience, to explain why he chose to use
quotes. I was asked by a number of readers of this group to subscribe and
participate. They saw my writing in a newsgroup that is predominated by
color scientists. I made the following point to one person that often
commented erroneously on that group:
"If you are going to pretend to be a color scientist, then
at least pretend to be a competent one."
I was reading something that Charles Poyton had written and it occurred to
me that he was quite gifted and some of the CONTRIBUTORS to this group
should follow his example. In a particularly nasty exchange on the
sci.eng.color news group, with the offender mentioned above(the offender was
NOT Charles or CDT, of course!), Poyton acknowledged that HE wasn't a color
scientist, but the basis of what he wrote was based upon consultation and
review by color scientists and other engineers. His role was to reduce a
very complex subject to a format that is readable and understandable to
people who have no formal training. He does this very well and I have found
that he is extremely careful in his use and explanation of technical jargon.
His technical ethics lend great credibility to his words.
I suspect that there are a great many people who come to this group for
information and help: Some just read to learn, some request very specific
information, others ask for recommendations about equipment such as is
Product A better than Product B? This is a completely open forum and one
should expect some irrational exuberance and strong opinions to be
expressed. I recently saw one of my competitors get lambasted by a well
respected contributor. My business side was smirking, but my technical side
was cringing. My company could have (and often has) been on the receiving
end of such criticism. In this particular case involving the competitor, the
contributor cited two tests which indicated a visual problem. That's
completely valid criticism. My competitor probably would have appreciated
those test results in a message off line. If they didn't listen or respond
to that critique, then they deserve whatever they get. Getting useful
feedback is a problem for all companies. Many companies use Sequel
technolgies in their own products, hence, we don't always get informed in a
timely fashion, that there is problem. One of the reasons that I and other
members of my staff, look at this group is to monitor potential problems
that never get back to us through the distribution chain.
Those who contribute to this group do a great service when they measure
their words with fact rather than opinion and teach us all with their
experience, rather than emotions. Those who read this group should remember
the openness of the forum contributes both positively and negatively to its
utility to the end user. When you enter here, it is definitely "Reader
Beware", but hey, that's all part of the fun!
