Abstract
Substrate treatment apparatus, printers, and methods to treat a print substrate are disclosed. An example apparatus includes a first roller having a rigid surface to receive a treatment fluid from a reservoir, a blade to apply a first pressure to the first roller to adjust an amount of the treatment fluid present on the first roller, and a second roller having a non-rigid surface to apply a second pressure to the first roller, to receive an adjusted amount of the treatment fluid from the first roller and to apply the treatment fluid to a substrate, the first pressure and the second pressure being selected such that the second roller applies the treatment fluid to the substrate in an amount resulting in a layer of treatment fluid less than about 0.4 micrometers thick on the substrate.
