    • PURPOSE: Provide is a method for manufacturing a gravure-transfer-coated steel plate, which is capable of transferring a pattern from a gravure-transfer sheet over a metal plate without any additional adjustment for processing conditions of a general PCM color line, thereby producing a gravure-transfer-coated steel plate having a beautiful appearance and a high workability. CONSTITUTION: The method for manufacturing a continued gravure-transfer-coated metal plate by transferring a pattern over a continued metal plate wound in the form of a coil using a gravure transfer sheet, comprises the steps of: coating, over the metal plate, a primer coating material essentially consisting of 20 to 40% of a polyester resin having a number average molecular weight of 5,000 to 20,000 while exhibiting a glass transition temperature of 10 to 50 C, 4 to 15% of a melamine resin, 1 to 10% of a urethane resin, 0.3 to 3% of isocyanate, 15 to 35% of a pigment, 30 to 50% of a hydrocarbon and ester-based mixed solvent, and 1.5 to 3% of additives; heating and setting the primer coating layer in a hot-air-blowing dry oven, thereby forming a lower coating layer; thermally pressing a gravure transfer sheet, printed with a desired pattern on a base film layer thereof, onto the lower coating layer; releasing the base film of the gravure transfer sheet from the lower coating layer, thereby transferring the pattern, as a transfer coating layer, to the lower coating layer; coating, over the transfer coating layer, an upper coating material selected from the group consisting of a thermosetting fluorine resin, a thermosetting polyester resin, and an ultraviolet-thermosetting polyurethane acryl-based resin; and heating and setting the upper coating layer or radiating ultraviolet rays onto the upper coating layer, thereby forming an upper coating layer.

    • PURPOSE: A method for manufacturing a non-clear gravure transfer printed steel sheet is provided which not only has various superior physical properties compared with a general printed steel sheet but also omits top clear coating process without any separate adjustment for the working conditions of a general PCM color line. CONSTITUTION: The method for manufacturing a non-clear gravure transfer printed steel sheet comprises the steps of forming a chromate layer for preventing rust on the plating layer when a base steel sheet or a plating layer is formed; roll coating primer paint on the chromate layer, heating and drying the primer paint coated chromate layer so as to form a primer coating layer; transferring the gravure transfer paper using heat and pressure after putting a gravure transfer paper in which a thermosetting resin layer and a printing layer are sequentially formed on a base film layer of the primer coating layer; and releasing the base film layer of the gravure transfer paper, wherein the thermosetting resin layer is practically cured when the gravure transfer paper is transferred on the primer coating layer.
    • 目的:提供一种用于制造不透明凹版印刷钢板的方法,其与普通印刷钢板相比不仅具有各种优异的物理性能,而且省略了顶部透明涂布工艺,而无需对一般工作条件进行任何单独的调整 PCM色线。 构成:制造非透明凹版印刷钢板的方法包括以下步骤:当形成基底钢板或镀层时,形成用于防止镀层上的生锈的铬酸盐层; 辊涂底漆在铬酸盐层上,加热干燥底漆涂层铬酸盐层,形成底漆涂层; 在将底漆涂层的基膜层上依次形成有热固性树脂层和印刷层的凹版印刷纸之后,使用加热和压力转印凹版转印纸; 并释放凹版转印纸的底膜层,其中当将凹版转印纸转印到底漆涂层上时,热固性树脂层实际上固化。
