紙護角在倉庫中存放時間過長。 如果從倉庫中取出后立即用于制造，由于溫度和濕度不適合印刷車間，它也會收縮和收縮。 紙角的起點和印刷廠通常不在同一地區(qū)，因此溫度和濕度會有所不同。 如果印刷廠不對印刷車間的溫度和濕度進行相對調(diào)節(jié)，則紙角不可避免地會收縮和收縮，從而影響印刷產(chǎn)品的質(zhì)量。
The paper corner protector is stored in the warehouse for a long time. If it is taken out of the warehouse and used for manufacturing immediately, it will shrink and shrink because the temperature and humidity are not suitable for the printing workshop. The starting point of the paper corner and the printing plant are usually not in the same area, so the temperature and humidity will be different. If the printing factory does not adjust the temperature and humidity of the printing workshop, the paper corner will inevitably shrink and shrink, which will affect the quality of printing products.
印刷機內(nèi)部的溫度高于外部自然環(huán)境。 交付部分紙角的散熱條件不可能完全相同。 熱量更快，中間的散熱更慢。 這不僅會導致紙角膨脹和收縮不一致，還會繼續(xù)引起諸如紙角變形的問題。
The temperature inside the press is higher than that outside the natural environment. The heat dissipation conditions of the corner of the delivery part cannot be exactly the same. The heat is faster, and the heat in the middle is slower. This will not only lead to inconsistent expansion and contraction of paper angle, but also continue to cause problems such as paper angle deformation.
UV印刷也會引起紙護角的膨脹和收縮。 在此階段，禮品盒通常在進入后期生產(chǎn)過程之前經(jīng)歷各種印刷過程，例如UV膠版印刷，凹版印刷和絲網(wǎng)印刷。 在UV膠版印刷中，紙角保護器在整個膠印過程中吸收并吸收大量水。 將紫外線燈直接暴露在紫外線燈下后，紙角保護器的溫度將升高并損失一些水分。 經(jīng)過一遍潤濕和一遍干燥的整個過程后，紙角會膨脹和收縮，在生產(chǎn)和加工過程中可能會出現(xiàn)產(chǎn)品質(zhì)量問題。
UV printing can also cause the expansion and contraction of paper corner protectors. At this stage, gift boxes usually go through various printing processes before entering the later production process, such as UV offset printing, intaglio printing and screen printing. In UV offset printing, the paper corner protector first absorbs and absorbs a large amount of water in the whole process of offset printing. After the UV lamp is directly exposed to the UV lamp, the temperature of the paper corner protector will rise and some moisture will be lost. After the whole process of wetting and drying, the paper corner will expand and contract, which may lead to product quality problems in the production and processing process.
紙護角進入倉庫后五天內(nèi)用于印刷和制造，這樣它們就可以融入當?shù)貧夂?，而不會在打印前后使紙角顯得很大。 橫向伸縮。
The paper corners are used for printing and manufacturing within five days after entering the warehouse, so that they can be integrated into the local climate without making the corners appear large before and after printing. Lateral expansion.
同一制造商生產(chǎn)的不同批次的紙護角在膨脹和收縮方面會有差異。 如果此紙角與同一批印刷品混合在一起，將會給生產(chǎn)帶來的不便。 從倉庫發(fā)送到印刷車間的每批紙護角裝置都不太可能馬上用完，通常會剩下少量。 其余的紙角將與興鑫的紙角一起打印，以進行下一次打印，但是由于這兩批紙角的膨脹和收縮不一致，因此很可能會出現(xiàn)產(chǎn)品質(zhì)量問題。
Different batches of paper corner protectors produced by the same manufacturer have different expansion and shrinkage. If this paper corner is mixed with the same batch of printed matter, it will bring inconvenience to the production. Every batch of paper corner guards sent from the warehouse to the printing shop is unlikely to run out immediately, usually leaving a small amount. The remaining paper corners will be printed together with Xingxin's paper corners for the next printing. However, due to the inconsistent expansion and contraction of these two batches of paper corners, product quality problems are likely to occur.
通常情況下，在一個生產(chǎn)車間中不容易進行印刷和印后加工等制造過程。 一些印刷公司甚為每個過程開設獨立的生產(chǎn)車間。 由于每個過程中常用的機械設備必須排熱，并且加熱能力不同，這也將導致每個生產(chǎn)車間的自然環(huán)境溫度和濕度不一致，從而影響紙張的膨脹和收縮 角落。
Generally speaking, it is not easy to carry out the manufacturing process such as printing and post press processing in a production workshop. Some printing companies even set up independent workshops for each process. Because the common mechanical equipment in each process must discharge heat, and the heating capacity is different, it will also lead to the inconsistency of natural environment temperature and humidity in each production workshop, thus affecting the expansion and contraction of paper.
