Richard, thanks for the explanations. I always assumed that the first number refered to the horizontal resolution and the second one to the vertical resolution. Then, what does the first mean?
Thanks,
Ray
"At the PhotoRet III setting, my camera shop told us to acheive a 300 ppi for our particular brand
of printer. Given your equation, I would end up having to send a file of resolution between 600 (x1)
and
780(x1,3) ppi."
Nope.
1200/4 x 1 = 300
1200/4 x 1.3 = 400
This is the range of PPI for optimal printing. IF the resolution of the printer truely is 1200 dpi. In the resolution, take whichever is lower, not higher. so a 720×2400 printer is really 720.
300 is right, and some claim the numbers for inkjets can go as low as .75. I am not going to vouch for that. 1-1 would seem to be the lowest I am comfortable with as you don’t get more detail in an image just by picking a different printer.
Clearer?
Thanks,
Ray
