dpi and ink usage

dpi and ink usage

2008-01-17 by Richard Smallfield

Hi,
I'm printing some fliers for an exhibition and wondered what the relationship is between dpi and ink use.

I tried printing some at 720dpi and after a gamma adjustment was surprised at how good the quality is. Would that save me some ink for these prints where quality is not crucial?

thanks,
Richard

Richard,

I never tried 720, but I know that 2880 lays down more ink than 
1440.  Using a profile designed for 1440, and printing at 2880 
results in a print that is too dark, due to more ink being laid 
down.  I assume 720 uses less ink than 1440.

Different printers have different characteristics.   A particular profile
may printdarker or lighter depending of the physical drop sizes.  There is
no general answer.
But if you are comparing a certain density of black ink the resolution
doesn't make
any difference.  In other words for particular print density its the same
amount of
whether you put lots of smaller dots (high res) or less bigger dots (low
res).
