I've been following this thread and now ICM has linked this solicitation fm RR in another thread.  I don't understand the request of 300dpi if  there is no corresponding finished image size constraints.  Or am I still losing out on the dpi debate?

Will not a 300 dpi render that is 3000x3000 result in a 10inch x 10 inch print that was printed at 300dpi?

Will not a 100 dpi render that is 3000x3000 result in a 3.3 in x 3.3 in print that was printed at 300dpi?

Will not a 100 dpi render that is 3000x3000 result in a 10in x 10in print but be of a lesser quaility?

If my assumptions are correct, should the 300dpi requirement not need a finished image size stipulated also?
