PP Printing Box's printing quality control is a key link to ensure product quality and meet customer needs. The following are the key steps of PP Printing Box's printing quality control:
Pre-printing quality control:
Original selection and processing: According to printing needs and expected effects, select the appropriate original type, such as reflective original or digital original. Evaluate the quality of the original, including resolution, color, level and clarity, to ensure that the quality of the original meets the printing requirements.
Color calibration: Perform color calibration on the printing equipment to ensure that the equipment can accurately restore the color of the original. This usually includes the use of professional color management tools, such as printing densitometers, to measure and adjust the color output of the equipment.
Plate selection and inspection: According to the printing process and substrate characteristics, select the appropriate plate type, such as CTP plate. Check the quality of the plate, including the flatness of the plate surface, the firmness of the coating, etc., to ensure that the quality of the plate meets the printing requirements.
Quality control during printing:
Ink adjustment: According to the printing process and ink characteristics, adjust the viscosity, dryness and other parameters of the ink to ensure that the ink can be evenly and stably transferred to the substrate.
Printing position and size inspection: During the printing process, regularly check whether the position and size of the printed matter are accurate to avoid deviation or misalignment.
Quality sampling: During the printing process, quality sampling is carried out to check whether the color, clarity, ink adhesion and other aspects of the printed matter meet the requirements. If problems are found, stop the machine and adjust them in time to ensure stable product quality.
Post-printing quality inspection and evaluation:
Finished product inspection: Conduct a comprehensive inspection of the printed PP Printing Box, including appearance quality, dimensional accuracy, color consistency and other aspects. Mark and isolate unqualified products to prevent them from entering the market.
Customer feedback collection: Actively collect customer feedback on the product, including product quality, performance and other aspects. Improve and optimize the problems reported by customers to improve customer satisfaction.
Continuous improvement and establishment of customer feedback mechanism:
Regularly review and improve the printing quality control process to adapt to market changes and changes in customer needs.
Establish a customer feedback mechanism to collect and handle customer feedback issues and suggestions in a timely manner, and continuously improve product quality and customer satisfaction.
Through the implementation of the above key steps, the printing quality of PP Printing Box can be effectively controlled and the product quality and competitiveness can be improved.
