Digital BW, The Print

As follow-up note on this Canon experiment, I'm now getting quite smooth
results with the printer.  The base needed more wetting agent.  About 3%
Photo Flo seems to work well.

 

I'm not 100% sure what the head arrangement is on the i9100, but some Canon
head information I've seen indicates that they use very small nozzles (1 pl
droplets) for half the inks, and larger ones (like 4 pl) for the others.
I'd guess that is what the i9100 has.  The light ink positions (Y, LC, LM)
don't tolerate the typical Epson viscosity at all.  However, the dark ink
positions are not having all that much trouble with Eboni.  They can't pump
much volume, so the dmax even with the M and C both loaded with Eboni is
down about 0.04 density units from what I'd expect with a modern Epson
printer.

 

It'll take some time to see if the system is reliable with this Eboni-based
inkset.  Aside from the somewhat modest dmax, however, it's putting out some
nice prints now.

A generous forum member loaned me this Canon to see how an Eboni-based
inkset might work on it. This is a dye-based hextone printer. In many ways
it is very similar to Epson printers like the 1280. 

The bottom line is that it also feels like going back to the 1280 in terms
of some of the dye-pigment problems, with a bit more print quality problems
than a good 1280 would have. It can make B&W prints that look very good at
a distance. However, it has a bit too much banding, at least with this
first test inkset. 

The paper transport seems better than Epson's.

I set it up to print with the Canon driver, curves and Create ICC. The dmax
with a double Eboni MK in the M and C spots is up to 1.65 on EEM, with the
average more like 1.63. A single Eboni cart in the K position can hit about
1.50. I used an Eboni-LLK in Y and 2 Eboni-LK densities in LC and LM. The
base was a glycerol 10 to water 25, with 0.5% Photo Flow, which gives a
viscosity that matches the Canon inks for the midtones. 

With respect to documentation, the printer is not quite up to the Epsons.

Note that this says very little if anything about the modern Canon pigment
printers. They are apparently a major advance for Canon. 

Happy Holidays,

Paul
