I'm trying to get PrintFab to get down to the level of black that the epson driver hits using Cone Color Pro Inks. Currently tried up to 150-200 saturation by modifying the printer tpm file. Also tried the built in profile of epson premium glossy with everything maxed up and GCR at max. I believe that oddly enough with this ink it is "blacker" when it is not mixed with c or m or y.
Epson Lab L value 4
Printfab Best L value 5.6 (with lots of ink pooling when printing blue)
Any advice?

Hello,
please excuse the delay. When creating your own profile, please folow these instructions:

If you suspect that it is better to use more black and less cmy, please select "Set ink saturation limit =200" when setting up the profile entry.
You can also increase black and leave cmy in the .tpm file
An L-value of 5.6 is still very good if you look at this table
of course, if you can reach L=4 with the Epson driver it should also be possible with PrintFab.

Code: Select all
[5760dpi]
Channels=k,c,m,y,c2,m2
Gamma=550
Saturation=50
Saturation_Y=40
Saturation_K=70 ;you can experiment with this value
...
Code: Select all
The following table lists the L-Value in the Lab system (100=white 0=black)
Canon Pro-10 Pro-100 Epson SC-P600 / P800
Plain Paper 27 38 Plain Paper 25 (Matte Black)
Matte HR-101 20 17 Matte Inkjet Paper 23
Matte MP-101 21 18 Archival Matte 16
Fineart FA-PM1 19 16
Glossy PT-101 8 6 Premium Glossy 3 (Glossy Black)

Re: Artisan 1430 (1500W) Black vs Epson Driver w/Cone Pro Inks
That was helpful I'm getting closer now. Printing in CMYK I'm trying to improve the gray balance of cmy to better match K (right now it's very cyan-green, even with m and m2 set to saturation 200) but it seems that light magenta is coming in too early in that combo. I see some other posts where people talk about modifying the built in curves. I see the sets of numbers under the entry you pointed out, but I'm not sure how they work. Could you provide a little info and also how the changeover from M to M2 (magenta to light magenta) happens?

Please excuse my delayed response.
Unfortunately, it is not possible to adjust the changeover from magenta/cyan to light magenta/light cyan - it is computed from the density tables.
You could try to switch off light cyan & light magenta by modifying the .tpm file. If this makes a big difference, it makes sense to measure the actual density curves for the Cone Color Pro inks (you would have to create and send in a linearization test chart).
