Cailang paper packaging color printing in thick paper printing and thin paper printing, there is a big difference, when printing thick paper, of course, to choose thick paper for printing machines such as Manroland, KBA, etc., should be printed thin paper Choose suitable for thin paper printing machines such as Heidelberg, Lee Youby and so on. The so-called thin paper generally refers to the following 300 grams of paper, the products commonly used in the enterprise album, books and magazines, color pages and other posters, and so on, the paper is often used in the packaging,

Offset printing paper, there are some suggestions:

1) When printing tissue paper, thin paper and thick paper (100 ~ 350g / ㎡) method is not the same, thin paper knock on the paper evenly knocked on, smooth, knock the paper interval even smaller, the best spacing, so as to avoid Causing wrinkles. Generally on the eager to machine on the printing of paper, only dragging the tip, so that the mouthpiece to keep flat, in order to smooth paper.

3) Feeding wheel as far as possible to adjust the light to the paper through the paper wheel can be successfully rolled to reduce the resistance to prevent paper curl.

4) for the light control system better machine, such as KBA, Komori series offset press, etc., to clean up the dry mouth of the paper dust, the best time to clean a time, so as not to affect the light control sensitivity, resulting in the machine for no reason to stop The Because, for thin paper printing, light control function is more important.

5) printing workshop temperature and humidity to be consistent with the paper library to prevent the paper from the side of the lotus or contraction, affecting the overprint and feeding smoothly. Conditional enterprises, the use of air conditioning or air humidifier can achieve better results, if no conditions can be taken to sprinkle and dry paper and other means to improve the paper printability.

6) printing thin paper, the printing speed is slightly better, delivery system and delivery system will be more stable. In general, the highest speed of 10,000 printing / hour machine, the speed is set to 6500 Indian / hour or so better; 15,000 Indian / hour high-speed machine, printing speed set at 9500 print / hour better
