This is for Steve. I am interested in either a canon i9100 or Epson 2100. All the reviews are very objective for most things but the image result is subjective. It is easy to technically evaluate a print but perhaps when doing comparisons of similar printers you could print the same image, same size from each printer compared. The ask say 100 members of the public to indicate which they think is the best print. Then publish a simple chart . Say there are 3 printers being compared you may get BEST PRINT A 7 B 13 C 80.
This indicates C to be the best option subject to other considerations like ink life, cost. speed etc. You may get a result like A3 B48 C49. This would indicate no disernable difference between B or C. Do you think it would be helpful.
