EPSON Ecotank printer, INK, official Driver on windows behavior

[ClarenceL]

Here is the patch sheet with 96 patches , I'm normally using it to profile small 4"x6" papers, but it's just fine for the fading tests since the the i1profiler software supports the data analysis - deltaE - averaging etc - with the data analyze tool so I don't need to run extra spreadsheets etc.
My version of i1Profiler does not let me create patch sheets with less than 400 patches, I was using the X-Rite Colorport software for the patch sheet definition long time ago which is very flexible in this respect, and you can export the patch sheet data in various formats -X-Rite compatible and import it into i1Profiler, and it accepts 96 patches - or more - or even less this way, I have an even smaller one with 50 patches which I tested against the Color Munki profiler kit.

There is a pretty nice, already rather old Java program, ColorInspector3D, which displays the color of an image file in various color spaces, this can show the distribution and the weight of the individual colors.
You can see that all colors and all outer edges are occupied by colors of the ptach sheet, and there is a pretty equal distribution long the surfaces and the inside of the RGB color space. You can play with other display options, and it displays in 3D. it does not allow you do overlays and does not support compressed .tiff files, but .png and other.

Thanks. The HP paper arrived.
It's almost the same how I use it in i1profiler. I just direct edit the txt patch files sometimes.

Prepared new test sets.
All dye inks, no any pigment. The 001/T502 K replaced by T673 K.
Only 1 printer this time: EPSON XP2101
The media type set to Matte STD.
Still tested on 3 papers, besides my original test charts by L365 driver.
Also Apply 96 patches version by WF2010 on HP Premium Plus photo paper Glossy.

That's another pretty large test you started here, I stated a few postings ago in one of my threads that my tests would be the last ones so I'm curious which results you'll get this time.

Print by XP2101 + T00V(T522) complete CMYK inks + EPSON Premium Semigloss 251gsm photo paper (4x6) SKU s041874
Compare between different drivers & media.
On matte paper media , the drivers designed for pigment black ink or DuraBrite Ultra always smaller gamut & lighter colors.
On EPSON Premium SemiGloss media (Besides L365 utilize K, others only CMY)
Worth to notice the ET-2800 improved K on Glossy but made browner greyscale.

I don't understand why even pigment K only driver also lighter on color inks when we select the matte paper.
So I always have some concern about using the driver designed for pigment ink on refill dye inks.

Also check on Epson Photo Quality Inkjet paper 105gsm (Presentation Matte)
Still lighter color on pigment based drivers.

Update the results after 30 days
It's the same ink, same paper & printer. But compare the driver & media type differences.

There are quite some variations in your measurements although I would have expected the overall results - measuring fading performance is a complex process and all variables - inks - paper - printer hardware and driver settings have an impact which cannot easily be anticipated and can make a difference at the end. There is a kind of hidden number set - the ratio of M/C changes in a very wide range for seemingly small changes in the starting conditions like printer type and driver settings

After 30days

I have another test on matte paper EPSON 720dpi(Low OBA) & another 3rd Party Paper(High OBA) start at the same date. Post results later.
The Evernew K seems works well on Low OBA paper only.
It's one of the reason why, on my previous tests the Evernew seems not so good.

The 82N Claria Photo(ink cartridge) & GI-73 still the best ink sets.

Seems a little strange on the K ink for T673 & 001+673K case, might be ink flush not enough when I switching the cartridge.
on Photo it's EPSON Inkjet paper on top, bottom for 115gsm Inkjet/matte paper.
Besides the worst 003 & 664 K, the high OBA paper seems get Evernew K visible color changed.
GI-73 seems the best ink here for different kind of the papers.
For balance between price & quality on different papers.
I would pick up the 673K + T502C + GI-73M + T502Y as a new sets for my general use.
Evernew should be fine to replace 664 & T522, but I would replace the K to 673.

Or even better, use the GI-73K to replace the 673K.

With all these variables - paper - OBC - ink brands - printer/driver etc you can create multidimensional matrices with the performance data , there are so many different papers on the market - many more than inks or printer models , testing all combinations could keep a test lab busy for a pretty long time but there is a trend when some tests are completed, and yes - the GI73 (53) inks are performing pretty good as well and you could - theoretically - combine inks - black from vendor A and cyan from vendor B , magenta and yellow from C which perform best on paper brand P , and you use another combination if you want to print on another paper type - o.k. - I won't go that far - I don't have enough space in the cabinet for that many different inks.

I have i1pro M0, could I identify the low OBA also based on the M0 reflexion?

If you build the UV source to shine on paper then read it by using the i1share app using light measuring mode, then you can see the bump of UV brighteners in the spectrum graph.

The hard part is to find suitable UV LED, and build super stable constant current analog source.

Here is a discussion about such LED constant current sources.
