Why Need 100% Print Inspection in High-Speed Printing

1. Ensuring Consistent Quality Across Every Print

Sectors like packaging, labeling, and security printing stake a reputation on the quality of printing, which in turn influences the performance of the final product. Minor imperfections, such as a misplaced logo or an ink smudge could be grounds for a complete batch rejection. Traditional method of manual inspection where only a small samples of prints undergo quality control checks can be flawed. In contrast to manual method, 100% print inspection systems provide a consistency that is unattainable through manual processes. They guarantee that each and every print is quality checked and no defective prints reach the customer. Quality control systems, which allow the inspection every single print runs, ensure consistency and quality to a degree that no other method can offer.

2. Minimizing Waste and Operational Cost

An important advantage of 100% print inspection is a decrease in waste. In high-speed printing, if a defect is not caught at an early stage, defective prints may run in large quantities before the issue is noticed. This wastes raw material, and needlessly increases expenses related to reprint and error correction. Automated systems inspecting everything in real time while defecting are avoided early in the process. Waste-materials and re-doing work on a large scale re-issue are substantial over time.

3. Increasing Production Efficiency

High-speed printing presses are constructed to run rapidly, creating thousands of prints each minute. The challenge of sustaining quality at such rates is to guarantee that each print is exhaustively verified, and that the process is not slowed down.
