提高印刷品光澤度的方法

來源:http://www.703248.com/   發布時間:2021-06-16
對于印刷來說是個技術活,除了按時按量的完成所有的印刷產品,印刷質量是為重要的,在檢查印刷質量的重要標準就是印刷產品的光澤度,在同樣紙張、油墨的條件下,由于操作工藝中存在問題,往往印刷后成品光澤相差較大。優良的印刷廠我們總結了幾種方法來提高印刷產品的光澤度:
For printing, it is a technical activity. In addition to completing all the printing products on time and in quantity, the printing quality is very important. The important standard for checking the printing quality is the glossiness of the printing products. Under the same paper and ink conditions, due to the problems in the operation process, there is often a big difference in the gloss of the finished products after printing. Excellent printing factory we have summarized several methods to improve the glossiness of printing products
1、改進酸性潤濕液。我國沿用幾十年的酸性潤濕液,以鉻酸、磷酸為主,雖經沖淡,但PH值仍在3。5~5。6之間。酸性越強,對油墨連結料和顏料的分解力、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 used for decades in China is mainly chromic acid and phosphoric acid. Although diluted, the pH value is still below 3. 5~5。 6. The stronger the acidity, the greater the decomposing power and corrosive power of ink binder and pigment, resulting in rough imprinted film surface and reduced gloss.

2、降低油墨乳化度。膠印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,干燥后光澤性差,而且還會產生一系列其它故障。
2. Reduce ink emulsification. The ink emulsification in offset printing is mostly caused by the large amount of water and ink in the operation. The ink layer looks very thick, but the ink molecules become oil in water state. After drying, the gloss is poor, and a series of other faults will occur.
3、油墨中適當地加放輔助劑。在油墨中加放適當的輔助劑,可以調節油墨的印刷適性,以便順利印刷。絕大部分輔助劑對于成品光澤都會帶來不利影響。
3. Add auxiliary agent properly in ink. Adding appropriate auxiliary agent in the ink can adjust the printability of the ink for smooth printing. The vast majority of auxiliaries have adverse effects on the gloss of finished products.
4、正確使用燥油。對于高 級的亮光快干油墨,在溫、濕度正常的情況下,自身已有足夠的干燥能力。
4. Use dry oil correctly. For high-grade bright quick drying ink, in the case of normal temperature and humidity, it has enough drying capacity.
5、注意噴粉。噴粉同油墨一樣,也會產生凝聚,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,噴粉裝置的機構上有加熱裝置,在使用噴粉時應加以檢查,加熱裝置是否失靈。
5. Pay attention to dusting. Dusting, like ink, will also produce condensation, especially in bags or barrels with poor sealing. When dusting is damped, it will condense into larger particles and spray on the wet ink mark, making the conjunctiva on the surface of the ink layer rough and reducing the original luster. Therefore, dusting should pay attention to moisture-proof. In addition, the mechanism of the powder spraying device has a heating device, which should be checked when using the powder spraying device to see if the heating device fails.
6、正確調節機器。印跡墨層厚度是否達到標準,對于光澤也有影響。例如壓力調節不良,網點擴大率高,墨層厚度達不到標準,成品光澤就稍差。因此,要把壓力調整好,使網點的擴大率控制在15%左右,所印的產品墨層既厚實,層次又拉得開,光澤也有了。
6. Adjust the machine correctly. Whether the thickness of imprinted ink layer meets the standard also has an impact on the gloss. For example, poor pressure regulation, dot expansion rate, ink layer thickness does not meet the standard, the finished product gloss is slightly poor. Therefore, it is necessary to adjust the pressure, so that the dot expansion rate is controlled at about 15%, the ink layer of the printed product is not only thick, but also open, and the luster is improved.
7、加凡立水(0號油)。這種油粘度很大,本身稠厚,可調節油墨濃度,使稀墨變稠,增加印品光澤度。
7. Garfanlishui (No.0 oil). This kind of oil is very viscous and thick. It can adjust the ink concentration to thicken the thin ink and increase the glossiness of printing products.
8、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,否則會降低油墨的干燥速度,出現粘臟、拉絲現象,影響光澤度。
8. Add the glossy paste. Glossy paste is made of raw materials with high glossiness, which can increase the luster of the ink, but the dosage should not be too large, otherwise the drying speed of the ink will be reduced, and the phenomenon of sticking and drawing will appear, which will affect the glossiness.
9、加入撤淡劑。當一些油墨顏色太深不符合專色印刷的要求時,需要將其調淺一些,這時不但可使油墨變淺,同時還能提高印品光澤。
9. Add the diluent. When the color of some ink is too dark to meet the requirements of spot color printing, it needs to be lightened, which can not only lighten the ink, but also improve the gloss of the print.
10、加入19#樹脂油。當油墨流動性與轉移性能不好時,可直接調入19#樹脂油,這時不但能提高油墨光澤,且不影響多色套印印刷的進行。
10. Add 19% resin oil. When the ink fluidity and transfer performance is not good, 19? Resin oil can be directly added, which can not only improve the ink gloss, but also do not affect the multi-color overprint printing.
