In trying a demo model at CompUSA it fed a whole stack of paper through on 1 print pass. Not
particularly impressive. But I have seen the Tiger on glossy paper - WOW~!
I'd appreciate your feedback. thx

Stay tuned.. there's a fix for the Epson's slow speed, at least on Macs.
Details forthcoming. LJ

I've been using lots of different papers in ES II and haven't had any
problem with multi sheet feeds. Zip. Nada. This includes long print runs of
10 to 30 hours straight.
Now if I could just convince it that PM6 and Powerpoint weren't enemy
applications ....

>I've observed multi sheet feeds with the Epson, have you seen that problem?
I've not had much problem with this. Seems to help to have a decent sized
stack of paper in the feed hopper. LJ
You've hit on one of the key points here - color matching is not absolute.
With the exception of the production graphic arts crowd, most users don't
actually want the exactly "right" color, they want their print out to
look good - which may be quite different than the original. For example,
on most monitors, green is pretty much a pastel. If I'm printing a business
chart, I want a nice, deep, solid green, not a pastel. In images, the
sky needs to be blue and the grass needs to be green - even if the original
is not very blue or not very green.
: What it boils down to is that color matching methods (i.e. Pantone,
: ColorSync 2.0, ICM [Win95 standard]) drivers need to be written still for
: all devices, the best scenario being having color matching (CM) support
: built-in to the OS. So, when it comes to CM support, Pantone currently is
: the hands down winner, even though its an application-specific
: implementation (i.e. Photoshop, Pagemaker etc., support Pantone), with no
: operating system support. ICM and ColorSync on the other hand, are OS-based
: APIs for color matching, but as of now, few software companies write to that
: spec.
True, but even when all of this software gets squared away, we won't
"be there" yet. The reason is the different color gamuts - some colors
can't be displayed on some/other devices. Most monitors can display
colors most printers can't print, and most printers can print colors that
most monitors can't display. In addition, even when a printer/monitor
can display a color, they will display/print some colors better than
others (i.e., on most color printers, very light colors show pronounced
dithering artifacts). If we shoot for a "perfect match", we have to
figure out what to do with out-of-gamut colors (a non-trivial problem)
and we need to figure out how to make it look good. Often, real
users prefer something non-matched to something matched due to the
marking/display technologies involved, which isn't going to be solved
by software.
: So what does all this babble mean? Well, easy to use, cheap color
: matching is still far away. The most practical solution is Pantone-based
: Color Matching Software (CMS), with the other OS-based CMS's, like ICM and
: ColorSync, hopefully right around the corner. So next time when it comes to
: color, look at the results of test printouts from computers at stores to see
: how close they match. And remember, colors still may not match when you use
: it with your home system. Despite the marketing hype of 'true color,' the
: likes of HP's ColorSmart mostly emphasizes certain primary colors that are
: used a lot (i.e. red, blue) to give the illusion that colors look closer to
: what's on the monitor. Although that's not color matching, I guess that it's
: better than nothing. But be forewarned, 'results may vary.'
Actually, ColorSmart does a variety of things (many of which are proprietary).
It does, however, do full color/gamut matching, but the goal isn't necessarily
an exact match. Rather, it attempts to make good looking images - instead
of technically "correct" but poor looking images. It also works with ICM
on Windows and ColorSync on the Macintosh to handle "true" matching, but
tests I've seen have said that most users actually prefer the output
with ICM/ColorSync off. Graphics arts professionals need an exact match,
but most consumers neither need nor want this. This is why, in an
industry that supposedly has this all figured out, Fuji & Kodak films
give substantially different color - they're trying to optimize the way
their films look, but not necessarily get the exactly perfect color
balance.
: I still like indicators like resolution and platform support as the
: primary reasons to buy, vs. any promise by a salesperson that a printer will
: print out the colors that you see on the screen. With color macthing for the
: average home consumer, it's relies on plain luck, although more than likely,
: most people will be satisfied with the colors they get from their printers.
: But a few may be disappointed.
Although it's used widely, dot placement resolution (which is what most
companies advertise) is a pretty poor metric, but it's unfortunately the
one most people jump to. Most 24-pin dot matrix printers are theoretically
360DPI in color - but you'd have a hard time convincing me they provide
better color print quality than a 300DPI (in color) DeskJet 855C. The
resolution is a factor, but others such as dot size/shape (note that very
few of the "720 DPI" printers on the market have a dot size that would
be correct for 720 DPI), ink compostion, ink interaction with paper,
color matching technology, halftoning technology, etc...
A good analogy is a sports car. When buying a sports car, should you
buy the one with the engine with the highest RPMs? If so, my chain
saw is a screamer. What you really do is drive the car - since the
performance of the car is actually a fairly complex interaction between
engine performance (which is partly max RPM, but also depends on the
torque curve, turbo vs. normally aspirated, etc.), the transmission,
the tires, the suspension, aerodynamics, etc.. Picking any one on which
to base your decision would be a mistake - just as it would be in
picking a color printer.
: So next time you think about color matching, just remember, whether the
: printer is an HP, EPSON, or whatever doesn't count.
I guess I'd have to disagree with you on that one ;-)
: You still have to see it
: with your own eyes to make sure.
:
This I'd agree with - but most retailers make this pretty difficult. The
ideal would be printing the same image on each printer in similar print
settings (best vs. normal vs. draft, etc.) on the paper you expect to use
most of the time. For most people, this a copier paper or a bond. If
you're going to print primarily on special papers, use the appropriate
special paper from each manufacturer. In general, I think you'll find
that most look pretty good on their special papers, but all but a few
( :-)) drop pretty substantially on plain papers.

I think that reaffirms the theme of my posting that color is still a matter
of preference. Unless it's a true color match to what's on the screen, it's
hard to expect a sizable majority of customers to 'like' a particular color
printout. Anotherwords, some people will worship ColorSmart; some won't.
Once a customer is satisfied with what he/she has created on-screen,
including an image's color selection, it should be the goal of the printer
to reproduce that as close as possible, not add color enhancements which
'certain' people prefer. Color matching should be the goal, giving consumers
the ability to find the colors they like best on-screen, instead of using
various (and conflicting) driver manipulations to attain a 'truer' color.
Ultimately, if a customer is satisfied with the appearance with the image
on-screen, the printer should be able to print it. So far that hasn't
materialized, but I'll wait just a while longer.
Glad I could be of help.

Actually, the vast majority of people do - it's through extensive real
user testing that we've determined what people prefer - and it's rarely
an exact match to their screen. For a small percentage that are very
color knowledgeable and particular, they prefer an exact match. For
the majority of consumers, they want something that looks good, and
they typically don't even know how to adjust an image so it looks
good on their monitor. If it looks good on their monitor, they want
it to look good on the printout - if it looks bad on the monitor, they
still want it to look good on the printout. They rarely care that
it looks the "same", just that it looks good.

For the small segment of the market that goes to the trouble of creating
images that they really care exactly what the colors are, this is true.
For the majority of customers, they want "the looks good thing". Full
system-based color matching will help, but users will typically want
the thing that looks good rather than the thing that is "right". Think
about it from an audio standpoint - most people actually don't like
their stereos "flat" - they want the bass cranked up and the treble
singing the cymbals, because it sounds "good". A lot more people want
boomboxes than high end, perfectly flat audiophile systems. That
doesn't mean that either are the wrong answer - only that different
people prefer different results. While you may be an "audiophile",
most people aren't - and any company that tries to sell "audiophile"
equipment to the mainstream market will likely lose in the marketplace.
: Ultimately, if a customer is satisfied with the appearance with the image
: on-screen, the printer should be able to print it. So far that hasn't
: materialized, but I'll wait just a while longer.
If the majority of customers ever get sophisticated enough to manipulate
images so that they are always "good" on screen - and they are always
able to deal with colors that may not look "good" on a printer that look
"good" on the screen - then maybe this will be true. For quite a while,
though, people are going to care more about "good" than "right" - and
for the purposes of making customers satisfied, right is by definition
whatever the customer prefers. I recently had a discussion with a
salesman at a high-end video store who mentioned that, for the few
discriminating customers who cared, they had to readjust the vast
majority of TV's they sell. This is because TV manufacturers crank
the color balance/vibrancy of most TVs, since this is what comsumers
prefer. It isn't "correct", but it is the right answer for most
customers.
