Pingchangxin: Why is color registration on the gravure printing press always unstable — jittering and slow to respond? Is it poor mechanical performance or a problem with the computer system? Zhou of Hangzhou Chaoyang Color Printing: Turn off automatic color registration. If there is no fluctuation, then it is a precision issue with the color registration controller; if the fluctuation is large, then check the guide rollers, bearings, locating pins, etc., and it is best to have the manufacturer inspect it. But what a printing press is really all about is tension — remember that tension and temperature must be moderate and must never be too high. Pingchangxin: I

[China Packaging Network news] Before you know it, one third of 2016 has gone by with a 'duang'.

Printability of Common Food Flexible Packaging Materials PE film has poor ink adhesion and requires corona treatment to improve it. Wetting tension is commonly used as an indicator to judge the quality of corona treatment. Generally, LDPE and LLDPE films are optimal at 38~420mN/m, and HDPE film at 40~44mN/m; polyamide inks are commonly used for printing. LDPE film has low tensile strength and high tensile elongation, making color registration adjustment difficult. Therefore, when printing
