為什麼加濕......為印刷業

Improve print productivity with optimum humidity! In the extremely competitive print market, humidity control is essential to maintain productivity at all stages of production and avoid machine downtime and waste.

紙

在暴露於幹燥空氣時，紙張迅速損失水分。紙張和卷筒紙紙通常生產和包裹，以保持在50±5％RH的濕度下的空氣平衡。當環境濕度低於該級別時，紙張從暴露的表麵下降到環境，改變其形狀，尺寸和物理性質。

Below 40%RH, the movement of paper on paper and other surfaces generates electrostatic charges, which cause it to stick together, attract dust and become difficult to handle.

Sheet Fed Offset

Unwrapped paper in a dry press hall will lose moisture from any exposed surface. Tight edges result, making the paper curl, causing misfeed, misregister, dot doubling and creasing as the paper passes between blanket and impression cylinders. Misfeed also occurs due to electrostatic build-up, making stacking difficult. Printed work awaiting another pass continues to change shape, resulting in misregister.

在整理過程中，具有低水分含量的紙張將沿著褶皺裂縫，從而產生較少的優質產品或增加的浪費。在新聞界和粘附中保持50-55％RH的相對濕度解決了這些問題。
