1. A printed board comprising:
a substrate; and
a printed pattern formed on the substrate,
wherein the printed pattern comprises one or more printed lines,
wherein the printed line comprises a polymer binder, a colorant, and a fluorine-based surfactant,
wherein the colorant is a black pigment or dye, or mixtures thereof,
wherein the colorant is comprised in a ratio of 25 to 85 parts by weight relative to 100 parts by weight of the polymer binder,
wherein in the printed line, the polymer binder is comprised 50 to 70 parts by weight relative to 100 parts by weight of the printed line, and
wherein the printed line has thickness uniformity, a difference between the maximum thickness and the minimum thickness, of 0.6 μm or less and an edge top deviation, an absolute value of a difference between an average thickness of the printed line and thickness of an edge portion of the printed line having the average thickness, of 0.55 μm or less.
