I am interested to know if you could print an image at 100dpi, so that when viewed at a distance of one metre, the image would be sharp and you could not make out each individual dot comprising the image.

I am basing this off my computer monitor which has 96dpi and when I view it at a distance of one metre, I can't see each individual pixel/dot making up the image.


I believe your ability to see each dot/pixel is determined by a 'circle of confusion' and the distance it is viewed at.


Is there a formula for this ?
