Thanks.

Richard - IS inks are being sold by a participant in the Nifty-Stuff Forum
(Measekite will have a wonderful time with this info). His name is Mikling,
and he is very knowledgeable and helpful on the Forum. He NEVER makes a
sales pitch and only has this information in his signature at the end of his
posts.

I emailed him to ask a question about IS inks presumably being sold by MIS
and Computer Friends. He told me that as a vendor you must sell IS inks
exclusively or sign an agreement with IS to not advertise that you sell IS
inks. (This certainly eliminates the possibility that you don't know what
you are getting, one of our troll's ongoing rants.)
MIS has several interesting inks for Epson printers, including B\W sets with
shades of grey instead of color inks. Of course, they come with custom
profiles. This is probably the best way to get excellent B/W prints on an
inkjet. I know that they are a customer/vendor of IS inks, so I guess that
they can't identify their products as IS because they have other sources for
some of their ink sets.

The email address for Precision Colors is http://home.eol.ca/~mikling/

If you want different quantities or have to fill in individual colors you
can email him and arrange for a different order from what is on the web
site. I haven't bought ink from him yet as I still have an adequate supply
of MIS inks. I will probably make my next order with him as he is very
helpful with people asking questions on the Forum, and his prices are very
competative.

Your liking??? Just what the hell does that mean? You called them? You
couldn't understand what they were saying? You couldn't read their web site?
Certainly you never ever bought any after market inks so who cares
whether or not you like "them"...whatever in the hell "them" means to you.
Are you aware of the fact that you come off as a complete and total idiot?
Did you know that?
If you haven't figured that out by not you must be completely brain dead!

I don't want to argue against 3rd party inks because many are fine,
however, your test is very subjective and not necessarily something to
draw a lot of conclusions from. Any print under glass will last longer,
as glass filters most of the most harmful short wave UV light spectrum.

The light level you discuss is vague at best in terms of trying to
compare it to any other.

Visual memory is not the best way to test if something has faded. A
reasonable inkset will fade about evenly with each color, so the overall
"aged" print shouldn't shift in color greatly, but that doesn't mean a
great deal of color and depth haven't been lost. To do a test, make two
copies and store one in a dark and pollution free area, and compare it
to the one that was exposed to light for 13 months, and then determine
about how much loss in density has occurred.

Accelerated light tests do not imply inks will fade rapidly. They do
rank inks based upon how the inks respond and how they would likely
respond in a longer exposure environment, as a result. Only the very
worse inks or ink and paper combos result in severe fading in weeks or
months.

I printed a copy of a one-page magazine article about my father for his
funeral 13 months ago. The article included both text and a color photo.
I used an HP PSC 2110 printer, Kodak Premium Picture Paper, and HP ink
cartridges that I had refilled numerous times with aftermarket ink.
Since the funeral, the print has been hanging on our living room wall,
framed in a dollar store frame and behind glass. While it is a bright
room, the spot where the print hangs does not receive direct sunlight at
any time.

So far, there has been no discernible fading whatsoever. The print looks
as good to me today as it did the day I printed it. I fully expect it to
look good for years to come.

Accelerated tests of the type done by many labs and/or magazines would
have you believe that aftermarket ink starts fading practically before
it finishes drying. Nothing could be further from the truth. With just a
moderate amount of care, aftermarket ink can last a good, long, time.
With poor care, even OEM ink will fade quickly.

product to a less expensive media.

The logevity has more to do with care and feeding than the media use to
store the data.

Some original movie film from the teens up are a bit dangerous but even
there one can still see the images.

FWIW I have some of the original Army training films. Now those will scare
you straight.

Again you know this how? Have you EVER worked in a manufacturing
environment?

Many manufacturing decisions are made based on a little as 1/2 cent in out
the door cost. (Want to take any bets on which of the decisions win? )

I have our resident troll (and his alter egos) $hit canned in my kill
file. What he doesn't know is that I continually backup data to the
latest medium and continually keep backing it up to current technology.
I have multiple backups on all kinds of media from tape to hard
drives. I really don't care about what I have on tape now because
EVERYTHING that I have on tape is now on CD, DVD and hard drive backups.
EVERYTHING I currently have on hard drives will be transfered to the
next great medium that comes along. If our resident troll doesn't
transfer his data to newer media as it comes to market then it is he who
is misinformed and doesn't really know the facts. But then he has shown
this to be the case time and time again.

Bull****.

CD and DVD dyes may not last "forever", but they will last many decades.
Lots of attempts to estimate the lives of some of them come up with
numbers in the 150 year range. None of them, properly burned on good,
working equipment, has a life anywhere near as short as only a decade or
two. And that is for the least stable of the dye types. Just don't
expect "-R" (rewriteable) media to have decades of stability. And do
understand that some drives are defective (low power laser) and don't
burn with enough power to properly heat the media to the proper
temperature, but that is not the fault of the dye.

All the back ups in the world won't help in all cases (think Katrina). We
have a policy of backing up each studio at all the other locations. Paid
off as we have yet to find as much as the foundation of the studio outside
of New Orleans.

Broad comments such as yours below should come with the necessary
warnings that they lack accuracy because they simply do not properly
consider the full field.

Studies of the dyes used in -R CDs, as well as the metal coating and
lacquer coating technologies, have shown massively variable results. In
some tests, especially during the periods when manufacturers were having
difficulties maintaining enough product, just prior to recordable DVD
technology becoming commonplace, some CD-R media began failures in as
little as 6 months from use. Many of these were made in countries with
poor quality controls in their factories, and many of those products are
no longer being produced, but many can have them in their collections.

Although I have not researched this issue recently, when I last checked,
very few CD-R media had expected 150 year ranges. As of a few years
back only specific dyes and use of sputtered gold came even close to 100
plus years expectations.

At the time I did research, archivists and professional services,
including the Library of Congress, were suggesting 10-20 year cycling
for critical materials and 35-40 years for highly redundant data.

Simply put, -R recordable technologies rely on organic dyes which are
vulnerable to light damage, and with CDs, physical damage, since they
are poorly protected only on one side by polycarbonate. Detachment of
the metal layer, oxidation of the aluminum surface due to mishandling or
the lacquer coating having been poorly applied with either air bubbles
or moisture had been fairly common.

The technologies used in -RW materials is quite different, and face
other antagonists, but may ultimately be more stable than -R. DVD
writable technologies differ in that the data surfaces are sandwiched
between two layers of polycarbonate plastic. They may prove more or less
stable as a result, but are better protected against physical damage.

However, just to reiterate, 150 years is an overstatement, and yes, some
CD -R materials have degraded in months and years. They may be the
exception, but implying that CD materials are regularly safe from data
lose for over a century is probably as equal an exaggeration as to state
that all CD -R materials will fail in 5 years.

For those who are concerned about their data on CD media, I would
suggest reviewing your CD-Rs every year or two for possible loss of
data, use sputtered gold coated CD-Rs for best longevity, and recognize
that a bigger problem may be the burners and drive technologies design
changes making media difficult to read, which may also suggest that
reburning every few years may somewhat protect you from those changes if
you upgrade your burners. Loss of media reading devices is probably
even a bigger risk than the media failure, but both need to be considered.
