IP5 upgrade for 2880 matte papers

IP5 upgrade for 2880 matte papers

2003-01-12 by jim hayes <jimhayes@frii.com>

Since I'm still working with getting rid of mottling on Eclipse paper 
with IP5 profiling, they e-mailed me the brand new driver which now is 
supposed to handle 2880dpi for matte papers, although I don't think 
any profiles exist yet.

Apparently the color printing is also improved somewhat. The confusing 
catch is that with the new driver, dated 12/24/02, if you want to 
print COLOR using the photoblack cart (PK as opposed to mk) at 1440dpi 
, not 2880, you have to download new profiles under the Epson 
2200-->PK folder. And I saw only three papers profiled there. These 
new profiles have a suffix "b" on them, thus the profile might be 
called for example 2200b_luster....you get the idea.

Or maybe not. It is confusing. Printing color at 2880 or greyscale at 
1440 (since no profiles for grey yet exist at 2880) are not affected.

The 95%ink reduction curve for Eclipse Satine BW paper which now 
exists cures 90% or more of the mottling. I may ask them to do a 90%k 
profile after another day or two of test strip drying. Otherwise I 
can't tell hardly any difference between the 100% ink and 95%ink 
reduction curves- side by side the output has been adjusted 
beautifully. The gradient change is nice and even, with the exception 
of some tone compresion around darker than maybe 94% or so.
