description	This research is to study different coating methods for burn mark accuracy in laser engraving process. The engraving process utilized Fiber laser machine. The raw material used for the specimen is Galvanized steel. There are four important parameters of laser engraving process that being recognised which are laser speed, laser power, laser frequency, and loop count. The coating materials used are spray painting, Polyvinyl Chloride (PVC) sticker, and Kapton film. Adobe Illustrator used to create the required design for engraving process. The experiment started with preparation of five Galvanized steel plate with required dimension. Each plate was coated with different coating material. Then the specimens were engraved by Fiber laser machine at the specified engraving parameters to obtain the finest burn mark on top of the plate. Then two testing were conducted which are surface roughness test and surface characterization. Surface roughness was conducted by using Mitutoyo Surftest SJ-301 stylus profilometer to obtain the roughness value (Ra). The best Ra value for uncoated metal is 1.17µm, for black spray paint is 1.09µm, for black PVC is 1.17µm, for red PVC is 2.84µm, and for Kapton film is 1.86µm. The worst Ra value for uncoated metal is 2.78µm, for black spray paint is 2.91µm, for black PVC is 4.29µm, for red PVC is 4.21µm, and for Kapton film is 2.90µm. Next, surface characterization was conducted by using a digital USB microscope. Good surface finish was generalized when there is no presence of burn marks, the coating material was fully eliminated, a complete square shape was produced, and no rusting appearance. Black spray paint and black PVC are the two coating materials that fulfilled the characteristics at all engraved fields.
