    • The present invention relates to a manufacturing method for a printing roll by anodizing and to a printing roll manufactured thereby. The present invention is characterized by comprising: a preparing step of preparing a metal roll; a metal membrane forming step of coating the surface of the metal roll with a metal membrane; an anodization treating step of using the metal roll as a positive electrode, putting the positive electrode and a negative electrode corresponding to the positive electrode into an electrolyte and forming pores by performing anodization treatment on the metal roll; and a widening step of putting the metal roll into an acidic aqueous solution. The present invention is able to form the pores of mesh shapes in fine patterns of nanosize by performing optimal anodization and widening treatment on the surface of the printing roll and is able to markedly improve the light transmittance of a transparent electrode since the pores are able to be uniformly and easily arranged.

    • 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.

    • PURPOSE: A producing method for a rotary screen is provided to form a continuous pattern of various designs. CONSTITUTION: A resist is sprayed on a mother roll. Herein, the mother roll is formed by plating nickel on an iron roll. A negative film of a screen shape is exposed on the mother roll for being developed. Nickel is plated on resist grooves on the mother roll to form a first plate unit. Then, the resist is displaced from the mother roll. The resist is sprayed on an upper portion of the screen of the first plate unit. Then, a pattern negative film of forming patterns is exposed on the resist to develop. Nickel is plated on the mother roll to form a second plate unit. Then, the resist is displaced from the mother roll. Heat is applied to a precipitate for replacing the precipitate from the mother roll.
