Disclosed is a substrate treating apparatus. The substrate treating apparatus may include a stage including an accommodation area, onto or from which a substrate is loaded or unloaded, and a treatment area, in which the substrate is treated, a liquid discharge head that supplies a treatment liquid to the substrate, and a liquid receiving part that receives the treatment liquid pre-discharged by the liquid discharge head in the treatment area.

A printing apparatus applies ink to a surface of a printing plate in the shape of a predetermined pattern and then transfers the ink to a substrate. The printing apparatus includes: an image recording section that applies the ink to the surface of the printing plate; a plate surface observation unit that acquires information about the surface of the printing plate; a storage section that stores information about a reference shape serving as a reference of the surface of the printing plate; and a determination section that compares the information about the reference shape stored in the storage section with the information about the surface of the printing plate, which is obtained by the plate surface observation unit, and determines whether or not the surface of the printing plate to which the ink has been applied is present in a predetermined range of the reference shape.

A ceramic ink may include about 20% to 80% by weight oxide frit, wherein the oxide frit is particles of at least one compound selected from silica, titania, alumina, zirconia, a compound having fluoride ion, bismuth oxide, zinc oxide, boron oxide, potassium oxide, sodium oxide, calcium oxide, barium oxide, lead oxide, lithium oxide, phosphorous oxide, molybdenum oxide, strontium oxide, and magnesium oxide; about 10% to 40% by weight infrared or near-infrared transmissive or reflective inorganic pigment; and about 10% to 40% vehicle.
