The present invention relates to a manufacturing method of an adhesive film for producing a light guide plate and a billboard and, more specifically, to a manufacturing method of an adhesive film for producing a light guide plate and a billboard, wherein each dot has excellent dimensional stability and the thickness of the light guide plate is uniform since a dot pattern is formed on an adhesive layer of a base sheet by forming a printing layer on a release paper and then laminating the printing layer on the adhesive layer, instead of a conventional gravure roll coating method. La présente invention concerne un procédé de fabrication d'un film adhésif pour produire une plaque de guidage de lumière et un panneau d'affichage publicitaire et, plus spécifiquement, un procédé de fabrication d'un film adhésif pour produire une plaque de guidage de lumière et un panneau d'affichage, chaque point ayant une excellente stabilité dimensionnelle et l'épaisseur de la plaque de guidage de lumière étant uniforme puisqu'un motif de points est formé sur une couche adhésive d'une feuille de base par la formation d'une couche d'impression sur un papier antiadhésif, puis la stratification de la couche d'impression sur la couche adhésive, au lieu d'un procédé de revêtement de rouleau de gravure classique. 본 발명은 도광판 및 광고판 제작용 점착필름 제조방법에 관한 것으로, 보다 상세하게는 기존 그라비아 롤 코팅 방식 대신 이형지에 인쇄층을 형성한 다음 기재시트의 점착층과 합지하는 방식으로 점착층에 도트 패턴을 형성하기 때문에 각 도트의 치수 안정성이 우수하고, 두께도 균일하게 형성할 수 있는 도광판 및 광고판 제작용 점착필름 제조방법에 관한 것이다.
