Hi

I'm evaluating trial PrintFab XXL for windows. There is statement in manual that Multi Black Cartridge is "also helpful to disable one or more cartridges if ink is low or if certain print heads are clogged." - That is my case, I would like turn off orange and green inks. But regerdless settings it still uses orange ink. I'm attaching screenshots...

How can I disable certain ink channels?

Hello,

unfortunately it is not possible to disable the orange cartridge when printing color images.

Only in screen printing mode (black & white with halftone raster), when printing with mutiple black cartridges (setting "Halftone Screen Mode"="Multi Black") it is possible to disable each cartridge individually.

In regular color printing mode it is possible reduce or completely disable light colored inks (light cyan, light magenta, grey, light grey) with the slider "Photo Inks" in the PrintFab driver settings, tab "Ink Ctrl".

So statement in your manual I have cited is completely untrue? (https://www.printfab.com/en/Printfab%20Manual.pdf page 54) Or is untrue only regarding to Epson 7900? Please let me know...

The statement in the manual that you cited is in the section "Special settings for screen printing" and it is correct, but it only applies to screen printing (printing black&white films).

Please let me know if questions remain.

So are you consider enabling that feature for color printing? It would be very useful for reviving old printers...
