Jinan label printing also has the characteristics of corrosion resistance, aging resistance, bright color, small shrinkage and expansion rate. If the corrosion resistance is poor, it is easy to age and fade, and the label made is not durable, it will affect the sales and use of the goods. If the shrinkage and expansion rate are large, it will not only affect the overprint accuracy, but also make the label deformed in use, affecting the sales and use of goods. In particular, the label of high-end goods should try to avoid the embarrassing situation that the goods have not expired, and the label has aged (label aging includes plastic aging, ink fading and other reasons). If necessary, the plastic or label shall be tested for aging resistance and its performance.

　　不干膠標簽材料外觀質量四點

　　Four aspects of appearance quality of self-adhesive label material1. 檢查不干膠標簽材料是否有毛邊，滾筒不干膠標簽材料邊緣是否光滑、清潔、無損傷，確保不干膠標簽印刷質量。

　　1. Check whether there is burr on the label material of self-adhesive and whether the edge of the label material of roller self-adhesive is smooth, clean and undamaged to ensure the printing quality of the label.

　　2、粘接劑材料在分切時，刀具調整或刀片不夠鋒利時，粘接劑材料棉紙或紙端會出現裂紋，檢查拉出的纖維將是一種粘接劑棒。裂紋可以是連續的，也可以是隨機的，膠粘材料可能出現在滾筒的一側，也可能出現在滾筒的兩側。所以膠料在上一臺印刷機上，仔細檢查打底紙和棉紙，看是否有小裂縫。然后拿一卷紙，在紙的再把它剝下來，檢查下面的紙和下面的紙是否有裂縫。由于裂縫有時非常小，只有底部的紙被分開，可以找到組織。值得注意的是，油墨和不干膠在打印過程中會逐漸積累，直到打印機的導輥，也會引起不干膠材料的邊緣裂紋。所以，即使它已經開始印刷，上面的問題也不容忽視。

　　2. When the adhesive material is cut, when the cutter is adjusted or the blade is not sharp enough, the cotton paper or paper end of the adhesive material will crack, and the fiber pulled out will be a kind of adhesive rod. The cracks can be continuous or random. The adhesive material may appear on one side of the drum or on both sides of the drum. So rubber material on the last printing machine, carefully check the backing paper and cotton paper to see if there are small cracks. Then take a roll of paper, peel it off at the end of the paper, and check whether there is any crack between the paper below and the paper below. Because the cracks are sometimes very small, only the paper at the bottom is separated and tissue can be found. It is worth noting that ink and adhesive will gradually accumulate in the printing process until the printer's guide roller, which will also cause the edge crack of adhesive material. So, even if it has started printing, the above problems can not be ignored.

　　3、不干膠材料邊緣是否粘連，背襯片水硅氧烷涂布，在邊緣或背襯紙不干膠材料附著涂層區域的部分硅油滲漏，在印刷過程中會造成紙張排氣光滑斷裂，不能正常生產。因此，印品上約有1米的材料粘接，另一方面在剝離前很長時間看邊緣或其他部位的剝離都沒有順利進行。通常,組織和紙粘附的底部邊緣的粘合劑材料發生在整個輥式涂布切削體積,并且通常只發生在外層7 - 10米,所以,遇到鼓膠粘劑材料的切割邊緣附著,不立即斷言,整個卷紙這個問題。

　　3. Whether the edge of the adhesive material adheres or not, the backing film is coated with hydrosiloxane, and the part of silicone oil in the edge or the coating area of the adhesive material of the backing paper leaks, which will cause the paper to exhaust smoothly and break during the printing process, and cannot be produced normally. Therefore, there is about one meter of material bonding on the printed matter. On the other hand, the peeling of edges or other parts did not go on smoothly for a long time before peeling. Generally, the adhesive material at the bottom edge of tissue and paper adhesion takes place in the whole roll coating cutting volume, and usually only takes place in the outer layer of 7 - 10 meters. Therefore, when the cutting edge of drum adhesive material is adhered, it is not immediately asserted that the whole roll of paper is a problem.

　　4、檢查滾筒不干膠材料分切端面是否平整，收卷松緊是否一致，如果滾筒不干膠材料分切端面不均勻，不僅會影響印刷登記，而且會由于模切位置的改變和廢料排放困難;收卷不一致會造成印刷時紙張張力的變化，不均勻的張力也會造成印刷質量問題。

　　4. Check whether the cutting end face of the roller self-adhesive material is flat and whether the winding tightness is consistent. If the cutting end face of the roller self-adhesive material is uneven, not only the printing registration will be affected, but also the change of the die-cutting position and the waste discharge will be difficult; the inconsistent winding will cause the change of the paper tension during printing, and the uneven tension will also cause the printing quality problem.
