A gravure coater test apparatus includes a gravure roll and a backup roll which are circumscribed to each other, a motor which drives the gravure roll partially submerged in a water-based pressure-sensitive adhesive for coating, a controller which adjusts the rotational speed of the motor, a doctor blade which is selected from a plurality of types to scrape the water-based pressure-sensitive adhesive from the surface of the gravure roll being rotated, and an infrared analyzer which allows at least one of the type of the water-based pressure-sensitive adhesive corresponding to the selected doctor blade, the uniformity of the coating surface, and the amount of the coated water-based pressure-sensitive adhesive to be confirmed.
