如果在市場上看到的一些光澤粗糙的產(chǎn)品，是因為沒有做提高光澤的工作，所以要想產(chǎn)品更好就要適當(dāng)提高光澤度，下面來講幾種方法。

If you see some products with rough luster in the market, it is because you have not done the work to improve the luster. Therefore, if you want to improve the product, you should appropriately improve the gloss. Here are several methods.

正確調(diào)整機器

Adjust the machine correctly

印刷的壓印墨層厚度是否符合標(biāo)準(zhǔn)也會影響光澤度。比如壓力調(diào)節(jié)不好，網(wǎng)點膨脹率高，墨層厚度不達(dá)標(biāo)，成品光澤度稍差。壓力要調(diào)好，使網(wǎng)點的膨脹率盡量控制在15%左右。

Whether the thickness of the imprint ink layer meets the standard will also affect the gloss. For example, the pressure adjustment is not good, the dot expansion rate is high, the ink layer thickness is not up to standard, and the gloss of the finished product is slightly poor. The pressure should be adjusted so that the expansion rate of the dot is controlled at about 15% as far as possible.

改進(jìn)的酸性潤濕液

Improved acid wetting solution

酸性潤濕液主要是鉻酸和磷酸。雖然已經(jīng)稀釋，但pH值仍然在3.5到5.6之間。酸性越強，油墨結(jié)合劑和顏料的分解和腐蝕能力就越大，造成壓印膜表面粗糙，光澤度降低。

The acid wetting solution is mainly chromic acid and phosphoric acid. Although diluted, the pH is still between 3.5 and 5.6. The stronger the acidity, the greater the decomposition and corrosion ability of ink binder and pigment, resulting in rough surface and reduced gloss of embossing film.

注意除塵

Pay attention to dust removal

除塵粉末會像墨水一樣結(jié)塊，尤其是在密封不良的袋子或桶中。噴粉受潮后會結(jié)塊成較大的顆粒，噴在濕墨跡上，使墨層表面粗糙，縮小原尺寸。有些光澤，所以噴涂時要注意保濕。噴粉裝置的機構(gòu)上有加熱裝置。使用噴粉裝置時，應(yīng)檢查加熱裝置是否有故障。

Dust removal powder will agglomerate like ink, especially in poorly sealed bags or barrels. When the powder is wet, it will agglomerate into larger particles and spray it on the wet ink, making the surface of the ink layer rough and reducing the original size. Some luster, so pay attention to moisturizing when spraying. The mechanism of the powder spraying device is provided with a heating device. When using the powder spraying device, check whether the heating device is faulty.

正確使用干性油

Proper use of dry oil

對于明亮快干的油墨，在常溫常濕下，具有足夠的干燥能力。在冬季低溫低濕的情況下，如需在油墨中加入防粘劑、脫粘劑、薄墨光油等，應(yīng)加干性油。

For bright and fast drying ink, it has sufficient drying capacity under normal temperature and humidity. In the case of low temperature and low humidity in winter, if it is necessary to add anti adhesion agent, debonding agent, thin ink varnish, etc., dry oil should be added.

山東印刷包裝認(rèn)為，在印刷操作中，正確使用干性油對成品光澤的形成是非常有利的。這是因為紙張吸收粘合劑需要一定的時間。在這個過程中，粘合劑盡快凝結(jié)，直到結(jié)膜干燥，這是成品光澤度好的關(guān)鍵。

Shandong printing and packaging believes that in the printing operation, the correct use of dry oil is very beneficial to the formation of finished product luster. This is because it takes time for the paper to absorb the adhesive. In this process, the adhesive coagulates as soon as possible until the conjunctiva is dry, which is the key to good gloss of the finished product.

所以如果要提高印刷光澤度可以從以上幾個方面入手嘗試，當(dāng)然也要注意有沒有問題的存在，做好預(yù)防工作很重要。更多信息就來網(wǎng)站775828.cn看看吧。

Therefore, if you want to improve the printing gloss, you can try from the above aspects. Of course, you should also pay attention to whether there are problems. It is very important to do a good job of prevention. For more information, please visit www.xinfengyinhua.com Let's have a look.
