This phenomenon, known as Die Registration Drift, occurs due to a gradual misalignment between the cutting rules and the printed graphics. Several factors contribute to this shift, including intense machine vibrations at high speeds, thermal expansion of the steel rules caused by friction, and dimensional changes in the paperboard due to environmental humidity fluctuations. This drift results in visible white margins on one side of the product and compromises the dimensional accuracy of the final package.

To prevent this deviation, operators must implement periodic inspection protocols (e.g., every 500 sheets) and ensure that all chase locking mechanisms are secure. Utilizing intelligent registration control systems that provide real-time sheet positioning adjustments is the most effective solution for eliminating this error in high-volume production.
