畫(huà)冊(cè)印刷的品質(zhì)關(guān)重要，我們時(shí)常關(guān)注畫(huà)冊(cè)的紙張多厚、油墨多鮮艷、封面多氣派，但是，我們千萬(wàn)別忘了畫(huà)冊(cè)印刷的品質(zhì)還包括其牢固度，試想一下，如果讀者翻著畫(huà)冊(cè)的時(shí)候掉頁(yè)了，這樣會(huì)讓讀者產(chǎn)生怎樣的感受。所以濟(jì)南畫(huà)冊(cè)印刷的牢固度很重要。

The quality of the album printing is very important. We often pay attention to how thick the paper is, how bright the ink is, and how stylish the cover is. However, we must not forget that the quality of the album printing also includes its firmness. Just imagine how the reader would feel if the page fell when turning over the album. Therefore, the fastness of Jinan album printing is very important.

通常，畫(huà)冊(cè)印刷多數(shù)采用膠裝，其中的標(biāo)準(zhǔn)便是熱熔膠厚度應(yīng)符合畫(huà)冊(cè)封面和紙張品種的厚度要求，可控因素包括背面加工，熱熔溫度，背面膠的厚度，后蓋和壓實(shí)度的質(zhì)量等。不過(guò)重要的還是以下兩點(diǎn)。

Generally, most of the album printing adopts adhesive binding. The standard is that the thickness of the hot melt adhesive should meet the thickness requirements of the album cover and the paper type. The controllable factors include the back processing, the hot melt temperature, the thickness of the back glue, the quality of the back cover and compactness, etc. However, the following two points are important.

一、溫度的把握

1、 Control of temperature

在畫(huà)冊(cè)印刷過(guò)程中，操作工對(duì)熱熔溫度的把控需要十分注意。不同類(lèi)型的熱熔膠和粘合劑一樣，隨著溫度的升高，粘度越低。當(dāng)溫度過(guò)高時(shí)，熱熔性粘合劑作為主要成分的聚合物，其熱解聚可能發(fā)生，從而降低了熱熔融粘合性。如果溫度過(guò)低，膠的流動(dòng)性差，粘結(jié)牢度的影響。目前，畫(huà)冊(cè)印刷用熱熔粘接劑的優(yōu)選使用的粘度和潤(rùn)濕性，在170℃-185℃時(shí)，它是在使用以進(jìn)行持續(xù)地加熱并保持恒定。

During the album printing process, the operator should pay great attention to the control of the hot melt temperature. As with different types of hot melt adhesives and adhesives, the viscosity decreases with the increase of temperature. When the temperature is too high, the thermal depolymerization of the polymer with the hot melt adhesive as the main component may occur, thus reducing the hot melt adhesion. If the temperature is too low, the fluidity of the adhesive is poor and the adhesion fastness is affected. At present, the preferred viscosity and wettability of the hot-melt adhesive used for album printing is 170 ℃ - 185 ℃, which is used for continuous heating and keeping constant.

二、厚度的控制

2、 Thickness control

要控制好粘接劑層的厚度。熱熔粘接劑層的厚度增加，粘合牢度會(huì)增加。當(dāng)厚度增大到一定值時(shí)，其牢度開(kāi)始下降。所以，如果使用的熱熔粘接劑層過(guò)厚，這樣不僅會(huì)導(dǎo)致膠和粘合劑牢度的下降，而且還會(huì)使畫(huà)冊(cè)的整體結(jié)構(gòu)遭到破壞。

The thickness of the adhesive layer shall be well controlled. The adhesion fastness will increase with the increase of the thickness of the hot-melt adhesive layer. When the thickness increases to a certain value, its fastness begins to decline. Therefore, if the hot-melt adhesive layer used is too thick, it will not only lead to the decline of the fastness of the adhesive and adhesive, but also damage the overall structure of the album.

另外，當(dāng)畫(huà)冊(cè)印刷背面太粗糙時(shí)，膠水中的紙張不容易滲入，因?yàn)楫?huà)冊(cè)紙毛聚集后其表面與空氣接觸會(huì)干擾膠水和紙張。所以不利于膠水的滲入，這樣就會(huì)影響畫(huà)冊(cè)的粘合，后就會(huì)影響到畫(huà)冊(cè)的裝訂質(zhì)量，這樣也會(huì)影響到畫(huà)冊(cè)后的印刷效果。所以，畫(huà)冊(cè)印刷的牢固度很重要。更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站http://775828.cn咨詢(xún)！

In addition, when the back of the album printing is too rough, the paper in the glue is not easy to penetrate, because the contact between the surface of the album paper and the air will interfere with the glue and the paper. Therefore, it is not conducive to the penetration of glue, which will affect the binding quality of the album and the printing effect after the album. Therefore, the fastness of the album printing is very important. Come to our website for more relevant content http://775828.cn consulting service
