How Hybrid Screening combines AM and FM for quality

How does Hybrid Screening combine AM Screening and FM Screening to optimize quality?

Hybrid Screening is an adaptive technique where the RIP software intelligently uses both AM and FM principles within a single image. It employs the regular, stable dot structure of AM Screening in the mid-tone areas to ensure consistent color and process stability, where the eye is highly sensitive to shifts. Concurrently, it switches to the finer, pseudo-random dots of FM Screening in highlight and shadow areas to maximize detail and texture reproduction, while eliminating Moire.

This targeted application minimizes the instability risks associated with pure FM, providing a stable press run while retaining the superior detail capacity needed for luxury projects. The technology, often branded as XM Screening, fundamentally offers a balanced solution, ensuring a soft visual transition between the stable AM grid and the high-fidelity FM dots, making it ideal for demanding commercial and packaging print jobs.
