Methods, systems and produced printed substrates are provided, which include substrates composed of one or more materials which are treated by an intermediate layer for normalizing surface energies and a digitally printed formulation adapted to the normalized surface energies. Surface energy normalization may be carried out by physical processes or by selective chemical processes. In an example, a self-assembled monolayer is applied to the surface of a printed circuit board to control ink jet dots by reducing copper surface energy and to improve ink adhesion. The self-assembled monolayer binds via an α group selectively and covalently to the copper on the board and binds via a hydrophobic co group to solder mask ink that is applied to the board. The co group participates in the solidification process of the ink. |
