Under the same conditions of paper and ink, due to the problems in the operation process, the gloss of the finished product after printing is often quite different. How to improve the gloss of Shandong packaging printing without considering the post press polishing treatment? Let's take a look at it.

1.改進(jìn)酸性潤濕液。我國沿用幾十年的酸性潤濕液，以鉻酸、磷酸為主，雖經(jīng)沖淡，但PH值仍在3.5~5.6之間。酸性越強(qiáng)，對(duì)油墨連結(jié)料和顏料的分解力、腐蝕力越大，致使印跡膜面粗糙，降低了光澤。

1. Improve the acid wetting solution. The acid wetting solution which has been used for decades in China is mainly chromic acid and phosphoric acid. Although diluted, the pH value is still between 3.5 and 5.6. The stronger the acidity, the greater the decomposition and corrosion of ink binder and pigment, resulting in rough surface of imprinted film and reduced gloss.

2.降低油墨乳化度。山東包裝印刷中的油墨乳化過度大都是操作中水大墨多造成的，印跡看上去墨層很厚，但油墨分子成了水包油的狀態(tài)，干燥后光澤性極差，而且還會(huì)產(chǎn)生一系列其它故障。水大墨多是山東包裝印刷中犯忌的做法，要改變這種狀況。    3.正確使用燥油。對(duì)于高級(jí)的亮光快干油墨，在溫、濕度正常的情況下，自身已有足夠的干燥能力。如遇以下情況應(yīng)加放燥油：一是在冬季溫、濕度偏低的情況下；二是油墨內(nèi)須添加防粘劑、去粘劑、薄調(diào)墨油等的情況下，都應(yīng)加放燥油。在山東包裝印刷操作中，正確地使用燥油，對(duì)于成品形成光澤非常有利。這是因?yàn)榧垙埼者B結(jié)料需要一定的時(shí)間，在此過程中，盡快使連結(jié)料凝聚，直至結(jié)膜干燥，是成品光澤好的關(guān)鍵。

2. Reduce the emulsion of ink. The excessive emulsification of ink in Shandong packaging printing is mostly caused by too much water and ink in operation. The ink layer appears to be very thick, but the ink molecules become the state of oil in water. The gloss after drying is very poor, and a series of other faults will occur. Water and ink is the most taboo practice in Shandong packaging printing. We should change this situation. 3. Use dry oil correctly. For advanced light fast drying ink, under normal temperature and humidity, it has enough drying capacity. In case of the following circumstances should be added dry oil: first, in the winter temperature and humidity is low; second, the ink must be added in the case of anti adhesion agent, anti adhesion agent, thin inking oil, etc., should be added dry oil. In Shandong packaging printing operation, the correct use of dry oil is very beneficial to the gloss of finished products. This is because it takes a certain time for the paper to absorb the binder. In this process, it is the key to make the binder agglomerate as soon as possible until the conjunctiva is dry.

4.注意噴粉。噴粉同油墨一樣，也會(huì)產(chǎn)生凝聚，特別是密封不好的袋裝或桶裝，噴粉受潮后，凝聚成較大的顆粒，噴到濕墨印跡上，使墨層表面結(jié)膜粗糙，降低了原有的光澤，因此噴粉要注意防潮。另外，噴粉裝置的機(jī)構(gòu)上有加熱裝置，在使用噴粉時(shí)應(yīng)加以檢查，加熱裝置是否失靈。

4. Pay attention to powder spraying. Like ink, dusting can also produce condensation, especially in bags or barrels with poor sealing. When the powder is damped, it will agglomerate into larger particles, which will be sprayed on the wet ink imprint, making the surface of the ink layer rough and reducing the original luster. Therefore, attention should be paid to moisture-proof in powder spraying. In addition, there is a heating device on the mechanism of the powder spraying device, which should be checked when using the powder spraying device to see if the heating device fails.

5.正確調(diào)節(jié)機(jī)器。山東包裝印刷的印跡墨層厚度是否達(dá)到標(biāo)準(zhǔn)，對(duì)于光澤也有影響。例如壓力調(diào)節(jié)不良，網(wǎng)點(diǎn)擴(kuò)大率高，墨層厚度達(dá)不到標(biāo)準(zhǔn)，成品光澤就稍差。因此，要把壓力調(diào)整好，使網(wǎng)點(diǎn)的擴(kuò)大率控制在15%左右，所印的產(chǎn)品墨層既厚實(shí)，層次又拉得開，光澤也有了。

5. Adjust the machine correctly. Whether the thickness of imprinted ink layer of Shandong packaging printing meets the standard also has an impact on the gloss. For example, poor pressure regulation, dot expansion rate is high, ink layer thickness can not reach the standard, the finished product luster is slightly poor. Therefore, to adjust the pressure, so that the dot expansion rate is controlled at about 15%, the ink layer of the printed product is thick, level and open, luster also has.

6.加凡立水（0號(hào)油）。這種油粘度很大，本身稠厚，可調(diào)節(jié)山東包裝印刷的油墨濃度，使稀墨變稠，增加印品光澤度。

6. Garfanlishui (No.0 oil). This kind of oil is very viscous and thick. It can adjust the ink concentration of Shandong packaging printing, thicken the thin ink, and increase the gloss of printed matter.

7.加入亮光漿。亮光漿由光澤度很高的原材料加工而成，可增加油墨的光澤，但用量不宜過大，否則會(huì)降低油墨的干燥速度，出現(xiàn)粘臟、拉絲現(xiàn)象，影響光澤度。

Add light to the light. Glossy paste is processed from raw materials with high gloss, which can increase the luster of ink, but the dosage should not be too large, otherwise it will reduce the drying speed of ink, sticky dirty, drawing phenomenon, affecting gloss.

8.加入撤淡劑。當(dāng)一些油墨顏色太深不符合專色印刷的要求時(shí)，需要將其調(diào)淺一些，這時(shí)不但可使油墨變淺，同時(shí)還能提高印品光澤。

8. Add diluent. When some inks are too dark to meet the requirements of spot color printing, it is necessary to lighten them, which can not only make the ink lighter, but also improve the luster of the printed matter.

9.加入19#樹脂油。當(dāng)油墨流動(dòng)性與轉(zhuǎn)移性能不好時(shí)，可直接調(diào)入19#樹脂油，這時(shí)不但能提高油墨光澤，且不影響多色套印印刷的進(jìn)行。

9. Add 19% resin oil. When the fluidity and transfer performance of the ink are not good, the 19 ? resin oil can be adjusted directly, which can not only improve the ink gloss, but also do not affect the multi-color overprint printing.
