dpi setting on inkjet printer?

I posted this in the 30x40 thread, but it got lost (right?).

 

I am interested in setting that others use on their printers.

 

I always use my Epson (currently a 2200) at the highest number of dots when I print final output.

 

When deciding on a PPI value I choose one that will divide evenly into the 1440 or 2880 of the printer DPI. I was making this choice based on not having to interpolate as a result of choosing a number that gives me a "left over."

 

So I use 180 or 360 rather than 300 or some other number with the wrong factor.

 

Is this sensible, or am I overlooking the fact that the printer is having to do math anyway no matter if I choose an even divider?

 

Thanks for any clarification.

I too have a 2200 and generally print at 300dpi and have been perfectly happy with the results. Perhaps I could eke out a slightly better print using a dpi which divides evenly into 1440 or 2880, but to my eye it's a matter of splitting hairs. I also always print at 1440; after doing tests on 8.5x11 and 13x19 paper using a number of different images the only thing thing that printing at 2880 did better than 1440 was increasing ink consumption.

Hi You got it right either 180 or 360 and it really is splitting hairs but why not!

If you can see split hairs in your shots then I'd say you have a mighty fine method right now

On the older UC ink printers, I found essentially no detectable difference between 300 and 360, but could see an advantage to 240 over 180. On my K3 ink printers, I can see a slight edge to 360 over 300, and hardly any difference between 180 and 240, so I routinely use either 360 or 180 with K3. Generally speaking, but not always, I use 360 up to 24"x and 180 for anything larger...
