ABW fun with Epson SC-P7000,
« on: December 29, 2015, 05:02:31 am »

Having received my Epson SC_P7000 I am very busy finding optimum printer settings and doing profiling for all the different papers I do my Fine Art Printing on.
Note: It is clear that this new generation is much more linear when printing without any color management (using ACPU).

Specifically for the Ilford Galerie Prestige Gold Mono Silk  I decided not to approach it via de colour route, but went for the ABW approach.

Very interesting, to say the least.

It is known that using ABW one can achieve even deeper blacks than via the colour approach, with this paper it is definitely so: with colour profiling it tops at Dmax  ~2.5, with ABW I got Dmax ~2.8 !
And with an almost ruler straight L curve.
The paper is on the cool side, so the L*ab shows.

The prints are made via Lightroom 5.7.1, setting printer manages color and selected ABW in printer driver menu, ABW set to dark.


I also printed an b&w image of a customer and the details remain nicely visible into the deep black, overall the image gains in dimensionality. I wish I had larger sheets available, must be impressive on A2 size or bigger. ( I have only a couple of A4 to test)


Attached is the result of the 51 step grey wedge, a linear ramp in L dimension (51 patches step=2)made in Lab space , then converted to AdobeRGB.

Looks excellent :-)
I'm wondering what information about the paper is used in ABW mode? If like the Canon version the ICC profile selection is not available, is the driver still receiving some information that will determine the Dmax for the paper you are using? If not, it would seem unavoidable that a choice of paper unable to support a Dmax of 2.8 will result in a plateau of density and so a vertical section of the L* plot at the lower left...

Have you tried the same experiment on a matte paper yet?

It looks like they added a bit of a negative bump (change of slope) down at the very bottom (92->98)

The printer settings are in the string at the top of the screen copy.
Trial and error needed to find an appropriate media type and setting of color density(aka Max ink limit).
Approach should be the same with canon.

I would not know. Like Keith Cooper describe on his website northlight-images.Co.uk you can make it even more lineair by using the icc create with the qtr tool.
ABW assumes gamma 2.2 and that matches quite nicely with this paper.

Hi George,

ColorDensity = 0

Let me know your results ;-)

Hi Jan
I didn't had enough time,to print more than 2 test prints A4 on VFAP matte paper.
The results, using the VFAP EPSON profile, were not satisfactory (dark and over
saturated) but I am not sure if this was my fault or not...
I will wait then,until a demo printer arrives at the Epson representative in Athens so
I can test much more.

Hi George,

On matte papers i find you need to reduce the color density to -8 or more.
I did a production on Innova IFA14 using Enhanced Matte Paper media type, with ColorDensity on -8%, and another on -12%
Nice blacks, lots of detail.
But i am still working on the matte papers, a difficult one to get under control.

Note: i make my own profiles.

Which printer did you buy?

I have not bought any printer yet.The test I have done was on a colleagues SC_P9000, thats why I didn't have enough time.I have just replaced the 9900 print head for the 6th time and i will wait 3-4 months to see what will happen with  the new SC_P9000.In the mean time ,I hope to have the opportunity to test it at the Epson representative in Athens ,when it arrives and of course read some reports on the behaviour of the printer.I am not in hurry any more!
My best wishes for the New Year! :)
