Re: You haven't increased the resolution....

For example, it's been said that the human eye can't discern much more than 300 dpi resolution. On the other hand, many can immediately discern the difference between a 300 dpi laserjet text print and a 1200 dpi laserjet text print. Why is this so if we can only discern 300 dpi?

Because that laserjet doesn't have a 1200 dpi color resolution in the first place, it uses dithering and therefore needs a lot more than 300 dpi in order to produce actual detail of 300 dpi.
