Inkjet prints are not carbon prints no matter how much carbon is in the ink sets. Carbon prints are carbon prints. The are made pursuant to a specific historical process. Let's not try to made inkjet prints something they are not. I call my inkjet prints pigment ink prints to distinguish them from dye ink prints. I eschew the term archival pigment prints. I don't know how archival they are.

I don't know how much carbon is in a P600 OEM ink print. So, I avoid referring to the P600 prints as "carbon prints."

In my B&W inksets and pirnting, I use as much carbon as possible to achieve the print tone I want. That, plus the best possible color pigments to pull the carbon warm hue to neutral, has historically been the best way to get the most archival, lightfast B&W inkjet print. The inkset I currently use is described here -- https://www.paulroark.com/BW-Info/7800-Glossy-Carbon-Variable-Tone-2016.pdf -- and follows that approach.

A 100% carbon print is warm on most papers -- about half way to sepia on glossy paper (which can be nice for old photo reproduction). That said, I can also make a 100% carbon print that is neutral enough on some matte papers, like Arches watercolor paper, that (with the right profile emphasizing the more neutral, higher density pigment dilutions) it can look neutral when displayed in normal lighting.. So, in my 7800 and 9800 I can print 100% carbon on matte or glossy paper. But I usually print neutral, using a color "toner" that uses the best color pigs I can buy.

MIS does still make its carbon pigments available. They set up a page with what is supposed to be what I use. See https://www.inksupply.com/roarkslab.cfm. The MIS or https://www.inksupply.com pre-mixed blue toner uses third party color pigments. I do not use these. I mix my own toner, which MIS does not sell. (It cannot make a profit using Canon retail-priced pigments.)

I have not done a comparative test between my P600's ABW mode neutral print and the variable-tone inkset I mix. I assume the ABW formula is very good, but since I generally don't use my P600 for the prints I sell or display, it's a moot point for me. With the 7800 variable-tone inkset (link above), using MIS carbons and Canon C and Blue, I'm sufficiently confident in the inkset performance to focus on other aspects of photography.

I was in the same situation and bought the Epson p600. However, for the foreseeable future I'm keeping OEM color inks in it. I need a color printer. That said, I assume the dedicated B&W inks that are available would work fine in it -- with some caveats. You might need to linearize profiles yourself. Also, I do not know about the quality of empty, refillable carts.

Hi all!

It's been a while since my last post... Life, familly and job, keep me quite away from my digital lab.

However, my old Epson SP 1400 died this week, so I need a new printer for my Eboni inks and I need your help folks... Which one should I choose? I had a quick look to Epson product line, and considering the fact that I9;m on Ebony, and that I' might move to Piezo HD one day, I saw 2 potential candidates: SC-P400 and SC-P600. P600 is listed by QTR, not P400.

> Is the P400 a good choice? Or is there any good reason to go to P600 (more expensive, of course)?

Thank you for your expertise and experience,

Have a good day.
