Packing Off-Line Overprinting is a controlled process used to print required batch details on cartons and shippers outside the main packing line. Before starting, line clearance must be confirmed and the correct status label should be displayed. The approved stereo or printer message is then set for the required batch. Suitable ink is selected according to the carton surface. The first printed sample must be checked and approved by two Production Officers and one Quality Assurance Officer, and the approved sample is attached to the Batch Packing Record. If the stereo is changed, a fresh sample must again be checked and approved. At the end of printing, the last impression is also verified and recorded. Rejected or excess printed materials are destroyed after batch packing. Overprinted cartons and shippers must be kept under lock and key with proper identification to prevent mix-ups, wrong printing, and unauthorized use during packing operations.

Impact Assessment
The Packing Off-Line Overprinting procedure helps ensure correct and controlled printing of batch information on cartons and shippers. Line clearance before starting the activity reduces the possibility of mixing old and new packing materials. Using the correct stereo, printer message, and suitable ink helps maintain clear and accurate printing. The first printed sample is checked and approved by Production and Quality Assurance before further printing, which helps prevent printing errors.
If the stereo is changed, a fresh impression is again checked and approved. The last impression is also verified to confirm that printing remained correct until the end of the activity. Overprinted materials are kept under lock and key with proper status labels to avoid unauthorized use or mix-ups. Rejected and excess printed materials are destroyed and recorded. Overall, this procedure improves packing accuracy, traceability, documentation, accountability, and control of printed packing materials.
