Slitting machines have evolved from rudimentary manual-tension devices to fully digital, servo-controlled systems operating well above 300 m/min. In China, the progression has followed a distinct three-generation path — from what the ind...

Flexible Packaging Gravure Printing: Complete Technical Guide

06/04/2026

Gravure dominates China's flexible packaging industry — over 94% of all soft packaging printing equipment and 95% of converters use it. The technology delivers speeds above 300 m/min with cylinder life of 3–4 million impressions, produci...

Registration Drift in Gravure: Electrical, Mechanical, and Process Fixes

Registration fluctuation — where the print randomly jumps in and out of alignment during a run — is harder to diagnose than steady-state misregistration because the fault is intermittent. It comes from one of three domains: the electroni...

Gravure Press Tension Control: Taper, Inertia, and Setup Guide

05/29/2026

Gravure press tension control is the difference between registration that holds and registration that chases itself across the roll. The machine has five tension zones — unwind, infeed, printing, outfeed, and rewind — and each one impose...

Pharma Packaging Eye Mark Control: Tension, Friction, Setup

05/26/2026

When a pharmaceutical packaging line rejects an entire batch of composite film because the eye marks won't track, the problem almost always traces back to one of four things: tension history, thermal shrinkage, friction coefficient drift...

Film Gravure Registration Defects: Causes, Prevention, Fixes
