I thought a custom profile would solve any print quality issue, such as Tiny white specks, correct color variations etc in a printed photo. Media is Domtar Nekoosa Lenin weight and thickness is within Canon specks. I read theres more than one type of profile or custom profile. Which do I need, I'm looking for quality prints without flaws such as the tiny specks, on my test prints thus far. The colors are not the same seen on the monitor, nor are they as bright. Looking for answers can anyone help? KSG
