MIS Associates has now put a light blue toner on its web page that clones the Canon pigment based toner I mix for my Glossy and Eboni Variable Tone inksets.

For the toner, go to the bottom of the MIS webpage at

https://www.inksupply.com/roarkslab.cfm .

(I allow them to use my name on their page as long as the inks are those I use or have tested. I receive no royalties.)

For a description of the latest version of the Carbon Variable Tone inksets, see http://www.paulroark.com/BW-Info/Glossy-Carbon-Variable-Tone.pdf

The MIS light blue toner is made with their color pigments and their amber base. I use Canon pigments and the amber base for my glossy compatible inksets. This same toner can also be used for the Eboni or other matte carbon variable tone inksets (like the Epson EcoTank carbon).

I have verified that the MIS toner works just like my Canon toner in terms of being plug compatible with the profiles I post.

I have not fade tested the MIS product. I assume (and I think MIS agrees) that it will have about the same characteristics as the previous MIS UT B&W inks. In my older fade testing the UT inks were competitive with other third party B&W inksets.

I will continue to use the Canon color pigments in my toner.

I hope the availability of a pre-mixed and reasonably priced toner is of use to the open source B&W market.

In the Yellow position, it is relatively easy to control the tone via Photoshop curves (blue curve controls Y-position toner), but as usual I prefer QTR.

Note that the MIS toner follows my more recent 25% color pigments to 75% base mix. In the initial Eboni VT inkset I used a 10% color to 90% base dilution. To adjust the profiles that used only 10% color pigs, divide the QTR ink load by 2.5. The ink load adjustment and the amount of color ink in the toner are (inversely) proportionate.

Note also that the MIS web page has an inaccurate color shown on its web page for the toner -- way too magenta. (They appear to have used a Lab A of 77 instead of the correct value of 7 for the image.) Also, their statement that what I use is just Canon blue is inaccurate. The toner I use is a combination of Canon blue and cyan.

So, if I use the MIS toner with the curves with VT in their name, I simply have to use this toner as is? I mean, I don't need to change its dilution at all? How do I know whether the profiles I'm using are the original 10-90 or the newer 25-75? (I mix my own, btw. using Eboni 1.1 and base b).

Thank you,
