Analysis of the Causes of Printing Defects in Label Products in The Quality Control Section at PT. XYZ with Fishbone Method

This study aims to analyze the factors that cause printing defects in label products in the Quality Control section of PT. XYZ. Data collection is carried out through observation of the production process, operator interviews, and analysis of inspection results. The analysis methods used include fishbone diagrams and the 5 Why approach. The results of the study show that the most dominant print defect in PT. XYZ is the result of blur printing (40%), followed by color mismatch (30%) and register inaccuracy (15%). The main causative factors come from human, machine, material, and inconsistent work methods. Recommendations for improvement at PT. XYZ includes regular engine calibration, improvement of operational standards, and operator training to reduce recurring defects. This research is expected to be a reference for companies in improving the quality of label production in a sustainable manner.
