Re: Epson 1400 vs 1800

Yes. Thanks again. I think I see what you are saying and it would
effectively be the same. I was looking for a way to have some control,
however slight, over the dottiness factor with BO as well as achieving
an enhanced d'max with uncoated papers. It's apparent that I still
have a long way to go in learning the intricacies of a rip and it's use.
