i'm new here, and new at printing as well. so far i have my eye on the epson 4800. knowing that it is impossible to get exact numbers, i looked around the web to get an idea of how much ink would cost per print, and found two sources that suggest the following:
$2.25-2.75 for 8x12in
$3.00-3.50 for 12x18in
$7.50-8.00 for 16x24in
are those figures roughly correct?
Wow - for ink alone, those figures appear quite high. About 2 years ago, I did a detailed analysis based upon the figures that my Epson 7600 reported averaged over a batch of 8 x 10 prints and using an ink cost of $0.50 per ml of ink. (That is $110.00 per 220 ml cart - so, if anything, it is a little high). According to my calculations at the time, each print consumed a total of 0.665 ml of ink which would place the ink cost at $0.33 per 8 x 10. If you include cleanings and waste, I would figure no more than $0.50 per 8 x 10.
While I am now using an Epson 7800 and have not done a detailed analysis, I cannot imagine that the ink cost factor is much more, if any. And, I cannot imagine that the Epson 4800 is laying down that much more ink.
Perhaps the cost figures that you were looking at included paper costs?
