A method for depositing a first coating on a top major surface of a glass sheet, and a second coating on a bottom major surface of the glass sheet, the method comprising: a) providing a coater having downward coating equipment, upward coating equipment, and a substrate support defining a path of substrate travel extending through the coater, the downward coating equipment being mounted above the path of substrate travel, and the upward coating equipment being mounted below the path of substrate travel; b) conveying a glass sheet along the path of substrate travel in a generally horizontal orientation wherein the top major surface of the glass sheet is oriented upwardly and the bottom major surface of the glass sheet is oriented downwardly; c) operating the downward coating equipment to deposit upon the top major surface of the glass sheet the first coating including a first film region comprising a first material and a second film region comprising a second material, the first material being different from the second material, the first film region being closer to the glass sheet than the second film region; and d) operating the upward coating equipment to deposit upon the bottom major surface of the glass sheet the second coating including a first film region comprising said first material and a second film region comprising said second material, the first film region being closer to the glass sheet than the second film region; wherein the first coating and/or the second coating including at least one further film region such that the first coating and the second coating are different; wherein the first film region of the first coating and the first film region of the second coating are deposited simultaneously in a shared chamber of the coater, and the second film region of the first coating and the second film region of the second coating are deposited simultaneously in a shared chamber of the coater. a) providing a coater having downward coating equipment, upward coating equipment, and a substrate support defining a path of substrate travel extending through the coater, the downward coating equipment being mounted above the path of substrate travel, and the upward coating equipment being mounted below the path of substrate travel; b) conveying a glass sheet along the path of substrate travel in a generally horizontal orientation wherein the top major surface of the glass sheet is oriented upwardly and the bottom major surface of the glass sheet is oriented downwardly; c) operating the downward coating equipment to deposit upon the top major surface of the glass sheet the first coating including a first film region comprising a first material and a second film region comprising a second material, the first material being different from the second material, the first film region being closer to the glass sheet than the second film region; and d) operating the upward coating equipment to deposit upon the bottom major surface of the glass sheet the second coating including a first film region comprising said first material and a second film region comprising said second material, the first film region being closer to the glass sheet than the second film region; wherein the first coating and/or the second coating including at least one further film region such that the first coating and the second coating are different; wherein the first film region of the first coating and the first film region of the second coating are deposited simultaneously in a shared chamber of the coater, and the second film region of the first coating and the second film region of the second coating are deposited simultaneously in a shared chamber of the coater.
