Re: [Digital BW] Re: BO 4000 Dither Pattern

Peter,

Is this at all printer dpi's? I ask this as my 1290 has a far superior
'micro-appearance' (=dither?) at 2880 dpi than at 1440dpi. I've not done a
detailed comparison of my 2100 yet at different dpi's.

As I said, I used to write inkjet drivers.  The obvious difference
between the 2200 and the 4000 is that the 2200 produces very obvious
patterns, which increase the visibility of the dots, and the 4000
does not.   There are essentially 2 kinds of dithers: random dithers
and patterned dithers.  The 2200's patterns don't look like a
patterned dither, they look like a badly done random dither.  So I'm
surmising that that's what needs to be fixed.
