Digital BW, The Print

Hi Carl,

 

Since I've been using QTR, I'm not sure how Epson has its driver set up, and
I'll defer to Roy with respect to QTR. 

 

I have not had a chance to see what I can do with the Epson driver and 260,
but I'll try that first with that printer.

 

I suspect there is more to be had from these drivers and learning how to
better control the dither pattern and dot size.  There is actually a chance
that dot size control might give some tone control.  I feel that I'm sort of
just scratching the surface now.

Paul,

Do you know what the dot size distribution is across the tonal scale 
for these "1.5 pl" printers? Epson describes the new printers, not 
as 1.5 pl printers, but rather Dx5 variable drop size. I'd assume 
that the smallest drop size (1.5pl) is used only in the highlights, 
but I don't really know that. Here is Epson's blurb:
"With DX5 (droplets x 5 sizes), each nozzle has advanced capabilities 
to discern and adjust the ink droplet size based on the needs of your 
print job."

Can you look at a 21 step printed grayscale and actually see 
different drop sizes on the print? Could also be resolution 
dependent where smallest drop sizes are only used at highest printing 
resolution.
