摘要： The present invention relates to a manufacturing method of a gravure print roll by using high velocity oxy-fuel spraying method and the gravure print roll. The method comprises a pretreatment step preheating the surface of a roll cylinder up to 80-100 °C to remove moisture and metal-working fluid; a step of grinding the surface by blasting the surface of the pretreated roll cylinder with iron or grit; a step for designing print patterns on the surface of tungsten carbide alloy being coated on the surface of the roll cylinder; a step of coating the surface of the roll cylinder with WC-cermet by high velocity oxy-fuel spraying method; a step of primarily polishing the surface of the roll cylinder with coated tungsten carbide alloy; a step of secondarily polishing the surface for removing polishing strain and obtaining gloss by a supermicro finishing method; a step of embossing the polished surface of the tungsten carbide with the print patterns by laser; and a step of removing burs generated from the printed patterns. A superhard coating layer is formed on the surface of the roll cylinder by using high velocity oxy-fuel spraying method from a tungsten carbide alloy superhard powder, the print patterns are formed by a laser processing method, after fine polishing steps, impurities are removed, and the surface is densified so the hardness of the printed surface and the abrasion resistance is improved, thereby remarkably improving print quality and the lifetime of the gravure print roll. [Reference numerals] (AA) Completing a gravure print roll; (S100) Pretreatment step of preheating a processed roll cylinder up to 80-100 째C to remove moisture and working fluid; (S200) Step of grinding the surface by blasting the surface of the roll cylinder; (S300) Step of designing print patterns on the surface of tungsten carbide alloy being coated on the surface of the roll cylinder; (S400) Step of coating the surface of the ground roll cylinder with tungsten carbide alloy by a high velocity spraying method; (S500) Step of primarily polishing the surface of the roll cylinder coated with tungsten carbide alloy by a grinder; (S600) Step of secondarily polishing the surface primarily polished with the grinder; (S700) Step of forming print patterns by graving uneven shapes on the surface of the tungsten carbide alloy by laser process; (S800) Step of removing burs remaining on the printed patterns
