Can Inkjet Do Direct Mail?

There’s a perception that inkjet can’t do direct mail and achieve the necessary image quality. Is that true?
To answer that, I guess we have to start by asking…what is it exactly that direct mail is supposed to do?
There isn’t one answer, just like there isn’t one kind of direct mail. “DM” ranges from the piece I find in my mailbox that tries to convince me that Abraham Lincoln’s birthday is the only time any sane person would consider buying a new mattress, to the glossy Cadillac catalog the company sends to me every year.
