Re: "Black Only" at 1440 vs. 2880 dpi (Epson 1280)

2004-02-12 by Peter A. Klein

Thanks, Paul and Bob.

Judging from Bob's remark, it sounds like it may not be worth it.  I 
do remember using 2880 with the glossy paper samples that came with 
the printer, and not noticing much difference apart from it taking an 
eternity to print a humble color 4x6.  Anyway, I'll try it with a 
small print and see if the difference is worth the time.

The object of all this is to get the dots a little smaller.  At 1440 
dpi, I can just seem them, and some would find this objectionable.  
The dots actually improve some things, like a digital camera 
snowscape I printed this week.  But sometimes they make grainy Tri-X 
pictures look even grainier. It almost seems like the kind of grain 
aliasing you get when you scan grainy B&W at 2700 dpi.  

I'm hoping that smaller dots might get the grain/print dot ratio off 
the "sour spot," just as a 4000 dpi scanner did for
