I have previously written that the instructions for Epson Sure Color
P-800 recommend that with Photoshoop CS3 or later, All LR and also PS
Elements 6 or later - the printer should manage colours. I have
confirmed that with CC LR having the printer manage colors gives a
vastly superior result when using Epson Premium Glossy paper. I may
now have discovered why this should be.

Epson in conjunction with the Rochester Institute of Technology have
taken color management to new levels. The problem appears to be that
while with 8 colors there are a zillion ways to blend them to achieve
a particular color there is only one best way. Apparently the
mathematics are complicated but are vastly simplified by use of a
massive Look Up Table (LUT). Presumably all this is built into the
driver.

Down loading the driver results in about a dozen ICC paper profiles
being installed in Windows\System32\spool\drivers\color but these can
only be used with LR and the like. They cannot be loaded into the
driver which reports that they are incompatible (or some such).

My suspicion is that the LUT is available only when the printer
manages colors. I don't know why this should be but that's what it
seems to be. Apparently Epson's larger printers have been using this
for a while and it is now moving to smaller models.

http://factor.bg/epson/SP9900/Maximu...r_fidelity.pdf is a blurb
which doesn't really tell you much.

https://www.youtube.com/watch?v=egLCg3GiXIE is also a blurb but gives
more information.

Whatever the explanation I am banging my head on the wall waiting with
great impatience for a version of the driver which incorporates the
profile for Archival Matte paper.

I suspect that your observation may be the result of a mistake somewhere.

The photo you posted the other day of flower in a vase, I was going to
comment on. I didn't see any issue with it viewed on screen, and it
was also totally within gamut (R3880) on gloss/pearl papers. I viewed
the photo on a large TV with laptop connected, yet that had no problem
displaying the colours without any obvious posterisation or other
issues. I didn't look on my calibrated system.
I'm confident it would print fine using "printer manages colour" and
default settings for Epson paper stock.
But a problem exists if using non Epson paper... Probably not too bad
in some cases though, as for example, I've printed using "printer
manages colour" with Ilford papers and Epson settings for similar
papers, and the result is probably close enough for most people.
However on matte papers, it's a different story, some of the reds were
definitely out of gamut. Sure - you could try it out and see, but I'll
stick with soft-proofing and adjustment and a colour managed print
process to ensure that I get WYSIWYG screenrint matches - rather than
a lottery.
I guess with Epson matte/fine art papers, those adjustments to avoid
out of gamut and to tweak colour could be used by editing while
soft-proofing, then send to the printer and allow the printer to manage
colour. With non-epson papers or custom profiles - then no, it won't
work.

Ilford has icc profiles for their papers and most printers.
http://www.ilford.com/printer-profile-list

I would be suprised if they have one for the Epson LUT technology. I
suspect Epson may be reluctant to let others use it.

It's not specific to the Epson technology, it fits the
ICC standard.

Waiting for Epson to supply a larger variety of profiles
is never likely to be productive! They have not done so
for many years, and are unlikely to change any time
soon. This is not an issue that just surfaced recently
or only for the printers you are looking at.

Perhaps the reason is obvious too, though I personally
don't think this should ever apply to consumer printer,
and don't even much like it for commercial photo
printers either! But the fact is that buying a Color
Monki and making your own custom profiles is a vastly
better solution. At the commercial level that is
extended to the point that a new batch of ink or a new
batch of paper (never mind just a new type or brand) is
cause to generate a new ICC profile. Note that some of
the commercial printers even come with spectrograph
hardware pre-installed.

Yes, all that's true. The problem is that if you do that all you would
produce is but another external profile which cannot be loaded into
the driver. You then do not have access to 'Printer Manages Color' or,
presumably, the LUT and associated software. You will see why I do not
want that from the two scanned images to the right of:
https://dl.dropboxusercontent.com/u/...%20compare.jpg

Then there is the matter of getting right:
Color Density
Drying Time per Pass
Paper Feed Adjustment
Paper Thickness
Print Quality Level
Print Quality
Speed
Finest Detail On/Off
Edge Smoothing On/Off
Colour Adjustment
Gamma
Setting

All of this comes in with the Epson profile. Otherwise you have to
work it out and set it yourself.

I'm not familiar with your printer or the driver, but I
doubt that comes from the profile (other than gamma).
The "profile" is an ICC profile. The rest of it is just
the set of options built into the driver (and regardless
of who wrote the driver, they are specified by Epson,
and available in the service manual for each printer).


When printing for fine art photography, there are some differences that
cannot be accounted for in any profile. The lighting conditions under
which the print will be viewed is one of them. I know one Nat Geo
photographer, who goes so far as to discuss how the image will be viewed
prior to printing. Obviously his prints sell for hundreds dollars for an
unmounted 12 x 18. For my camera club competition prints a make
adjustments for CC viewing conditions. e.g. a print that looks great
hanging on a wall, with normal room lighting, would look washed out in a
CC light box.

I can assure you that all Epson drivers I have had anything to do with

I don't yet know about the P800 but with my 3800

The driver has more options that just which ICC profile.
Options such as paper thickness are not part of a

They are not part of an ICC profile. But they are part of the file

I've never explored those files but I do know how they behave.

I must be older than you. I remember the days when hardwired meant

Those were the days when wires meant wires.

Even if it doesn't do it now (and I don't know that it doesn't), the
setting for 'Media Type' in the driver control panel used to select
the profile provided by Epson, also set up set the paper thickness as
well as other things. This was the case irrespective of whether you
used the profile in the driver or the spool directory.

Typical Eric, totally wrong... but still argues in circles that go round
and round in circles.

The profile is about *color*. It has nothing to do with anything
other than color variations between paper types and ink.

The rest of it is printer configuration, not a profile. There
are a number of preset configurations *hardwired* into the print
driver, all using information available in Epson service manuals.

If you need an analogy: it's like JPG file which contain a compressed

it cannot be easily modified, as opposed to data in some

variable that a user or hacker can easily modify.

Try also http://www.thefreedictionary.com/hard-wired

hard·wire or hard-wire (härd'wir')
tr.v. hard·wired, hard·wir·ing, hard·wires or hard-wired or
hard-wir·ing or hard-wires
1. To connect (electronic components, for example) by electrical
wires or cables.
2. To implement (a capability) through logic circuitry that is
permanently connected within a computer and therefore not
subject to change by programming.

which shows that printing with colour management via the printer
produces a result vastly superior to printing with LightRoom managing
colors. The 'Printer Manages Colours' is hard to distinguish from the
cut and paste from the original file.

LightRoom uses the external profile for the paper, as stored in the
\spools directory. The Printer managed version uses the profile in the
printer. Clearly there is a difference and from what I have read it is
more than just a basic color profile.

Ilford has icc profiles for their papers and most printers.

.... and I responded:

I would be suprised if they have one for the Epson LUT technology. I
suspect Epson may be reluctant to let others use it.

.... and you replied.

It's not specific to the Epson technology, it fits the
ICC standard.


To continue: as I have previously written, I would not be surprised if
Epson was reluctant to let competing paper manufacturers have the data
which enables them to create profiles which use the LUT technology
which seems to require that they can be loaded into the driver. I have
already established that whatever is in those profiles, they are not
compatible with the profiles loaded in the \spool directory.
