低溫天氣對印刷紙張的影響!

印刷生產中,紙張是對環境溫濕度要求極高的耗材之一,紙張為多孔物質,其基本結構是由植物纖維和輔料組成,具有較強的親水性,若環境溫濕度得不到良好控制,會導致紙張變形,影響正常印刷。因此,保持適宜的環境溫濕度是提高紙張印品品質和提高生產效率的關鍵。
In printing production, paper is one of the consumables which have high requirements for environmental temperature and humidity. Paper is a porous material. Its basic structure is composed of plant fibers and accessories, which has strong hydrophilicity. If the environmental temperature and humidity are not well controlled, it will lead to paper deformation and affect the normal printing. Therefore, to maintain the appropriate environment temperature and humidity is the key to improve the quality of paper printing and production efficiency.
普通紙張對于環境溫度的要求不那么明顯,但當環境溫度低于10℃時,普通紙張就會變得很“脆”,印刷過程中墨層在其表面的附著力就會下降,容易造成脫墨現象。
The requirement of ambient temperature for ordinary paper is not so obvious, but when the ambient temperature is lower than 10 ℃, ordinary paper will become very "brittle", and the adhesion of ink layer on its surface will decrease in the printing process, which is easy to cause deinking phenomenon.
金銀卡類紙張通常是以銅版紙、白板紙、白卡紙等為基材,然后再復合PET膜或鋁箔等材料生產而成。金銀卡類紙張對環境溫度的要求更高一些,這是因為金屬和塑料材質對于溫度的變化都非常敏感.
Gold and silver card paper is usually made of coated paper, white board paper, white card paper, etc., and then compounded with PET film or aluminum foil. Gold and silver card paper requires higher ambient temperature, because metal and plastic materials are very sensitive to temperature changes
當環境溫度低于10℃時,將大大影響金銀卡類紙張適性,當金銀卡類紙張的儲存環境溫度在0℃左右時,從紙庫運送到印刷車間后,其表面就會因溫差而出現大量水汽,影響正常印刷,會導致廢品出現。如果遇到上述問題,而且交貨期緊張,工作人員可先打開UV燈管讓紙張空跑一遍,使其溫度與環境溫度相平衡后再正式印刷。
When the ambient temperature is lower than 10 ℃, the suitability of gold and silver card paper will be greatly affected. When the ambient temperature of gold and silver card paper is about 0 ℃, when it is transported from the paper warehouse to the printing workshop, a large amount of water vapor will appear on its surface due to the temperature difference, which will affect the normal printing and lead to waste products. If you encounter the above problems, and the delivery time is tight, the staff can first turn on the UV lamp to let the paper run again, so that its temperature is balanced with the ambient temperature before formal printing.
此外,低溫干燥,相對濕度低,紙張與空氣進行水分交換,紙張變干燥,變翹,收縮,會造成套印不好。
In addition, low temperature drying, low relative humidity, paper and air moisture exchange, paper drying, warping, shrinkage, will cause poor overprint.
