Does anybody have any idea as to why ACR is set to 240 ppi by default? Isn't 300 ppi the optimum setting for printing purposes? Is there a good reason, or reasons, why Adobe chose 240 ppi as the default setting?
I'd like to know if it is advisable to change ACR's settings from this default 240 ppi to 300 ppi. I know any perceived difference, when it comes to printing images, may be negligible, but why not, if it is just a matter of simply changing it to 300 ppi permanently?
I am uneasy about changing this, however, until I find out a lot more about it, as I want the best quality, and if there are undesirable consequences by changing ACR to 300 ppi that I am not aware about, and, therefore, why Adobe have it set it to 240 ppi, then I'll leave it at the default setting.
