The paper corner guard 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 plant does not adjust the temperature and humidity of the printing workshop, the paper angle will inevitably shrink and shrink, which will affect the quality of printing products.

印刷機(jī)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(huì)導(dǎo)致紙角膨脹和收縮不一致，還會(huì)繼續(xù)引起諸如紙角變形的問題。

The temperature inside the press is higher than that in the external environment. The heat dissipation conditions of the paper corner of the delivery part cannot be identical. The heat is faster and the heat in the middle is slower. This will not only lead to inconsistent expansion and contraction of paper corner, but also continue to cause problems such as paper corner deformation.

UV印刷也會(huì)引起紙護(hù)角的膨脹和收縮。 在此階段，禮品盒通常在進(jìn)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(hù)器在整個(gè)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(hù)器的溫度將升高并損失一些水分。 經(jīng)過一遍潤(rùn)濕和一遍干燥的整個(gè)過程后，紙角會(huì)膨脹和收縮，在生產(chǎn)和加工過程中可能會(huì)出現(xiàn)產(chǎn)品質(zhì)量問題。

UV printing can also cause the expansion and contraction of paper corner guard. At this stage, gift boxes usually go through various printing processes, such as uvoffset printing, gravure printing and screen printing before entering the later production process. In uvoffset printing, the paper corner protector first absorbs and absorbs a large amount of water in the whole offset printing process. After the ultraviolet lamp is directly exposed to the ultraviolet lamp, the temperature of the paper corner protector will increase and some moisture will be lost. After the whole process of wetting and drying, the paper corner will expand and shrink, and product quality problems may occur in the process of production and processing.

紙護(hù)角進(jìn)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(dāng)?shù)貧夂?，而不?huì)在打印前后使紙角顯得很大。 橫向伸縮。

Paper corner guards are used for printing and manufacturing within five days after entering the warehouse, so they can blend 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(hù)角在膨脹和收縮方面會(huì)有差異。 如果此紙角與同一批印刷品混合在一起，將會(huì)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(hù)角裝置都不太可能馬上用完，通常會(huì)剩下少量。 其余的紙角將與興鑫的紙角一起打印，以進(jìn)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(huì)出現(xiàn)產(chǎn)品質(zhì)量問題。

The expansion and shrinkage of corner guards of different batches produced by the same manufacturer will be different. If this paper corner is mixed with the same batch of printed matter, it will bring inconvenience to production. It is unlikely that each batch of paper corner guards sent from the warehouse to the printing shop will be used up immediately, usually a small amount will be left. The rest of the paper corners will be printed together with the paper corners of Xingxin for the next printing. However, due to the inconsistent expansion and contraction of the two batches of paper corners, product quality problems are likely to occur.

通常情況下，在一個(gè)生產(chǎn)車間中不容易進(jìn)行印刷和印后加工等制造過程。 一些印刷公司甚為每個(gè)過程開設(shè)獨(dú)立的生產(chǎn)車間。 由于每個(gè)過程中常用的機(jī)械設(shè)備必須排熱，并且加熱能力不同，這也將導(dǎo)致每個(gè)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。

In general, it is not easy to carry out printing and post press processing in a production workshop. Some printing companies even set up separate workshops for each process. Due to the fact that the mechanical equipment commonly used in each process must exhaust heat, and the heating capacity is different, this will also lead to different natural environment temperature and humidity in each production workshop, thus affecting the expansion and contraction corner of paper.
