            為了保護不干膠標簽的印刷圖案,提高標簽的質量,目前不干膠標簽印刷后很多都選擇了覆膜、上光、燙金等表面處理。
            In order to protect the printing pattern of adhesive labels and improve the quality of labels, many of them choose coating, polishing, bronzing and other surface treatments after printing.

            上光技術主要應用于鏡面涂布紙、涂布紙類標簽的表面涂布,其目的是增加其表面光澤度,并達到防污、防潮、保護圖案。按加工方法,標簽材料上光分為單張紙上光和卷筒紙上光,其中卷筒紙是標簽印刷工藝中較常用的方法。
            The polishing technology is mainly applied to the surface coating of mirror coated paper and coated paper labels. Its purpose is to increase the gloss of the surface, and to achieve anti-fouling, moisture-proof and protection patterns. According to the processing method, label material polishing can be divided into sheet paper polishing and web paper polishing, among which web paper is the most commonly used method in label printing process.

At present, the universal application of UV polishing technology is that the printed pattern surface is evenly coated with a layer of UV polishing. Flexographic label with water-based ink is an indispensable process for lightweight printing.

            二、UV上光工藝應注意以下事項:
            2. The following points should be paid attention to in UV polishing process:
            1、對油品質量進行驗證
            1. Verification of Oil Quality
            UV上光,有一定的存儲周期,和環境有一定的要求,所以使用前四川應該檢查玻璃的顏色和量化涂層干燥后,和添加劑的匹配,還注意觀察與油墨是否有反應。一般要求先進行上光試驗,然后投入正常生產。

            UV polishing has a certain storage period and certain environmental requirements, so before use, Sichuan should check the color of glass and quantitative coating after drying, and the matching of additives, and pay attention to whether there is reaction with the ink. Generally, it is required that the polishing test be carried out first and then put into normal production.
            2、關于油的厚度
            2. On the Thickness of Oil
            UV清漆性能不如溶劑型清漆好,如果涂布量過大會使表面出現淺色條紋,影響光的反射效果。涂布量過大會使上油干燥不徹底,只會使表面干燥,造成復卷后粘連。
            The performance of UV varnish is not as good as that of solvent varnish. If the amount of varnish is too large, light stripes will appear on the surface, which will affect the reflection effect of light. Excessive coating will not dry the oil thoroughly, but will only dry the surface and cause adhesion after rewinding.
            3、關于油的粘度和表面張力
            3. On Oil Viscosity and Surface Tension
            其粘度對其流平特性、干燥速度、表面光澤度都有影響。根據不同的紙張,調整適當的粘度。在控制粘度的同時,還要注意油的表面張力的變化。使清漆的表面張力小于油墨層的表面張力,這樣,清漆就能完全濕潤表面,避免出現針孔、條紋等質量問題。
            Its viscosity has an effect on its leveling characteristics, drying speed and surface glossiness. Adjust proper viscosity according to different paper. In addition to controlling the viscosity, we should pay attention to the change of oil surface tension. Make the surface tension of varnish less than that of ink layer, so that the varnish can completely wet the surface and avoid pinholes, stripes and other quality problems.
            4、速度、涂膜量、壓力、干燥溫度
            4. Speed, Film Volume, Pressure and Drying Temperature
            上光涂布速度、涂布量、壓力和干燥溫度四種因素相互制約,根據紙張表面的不同對其潤濕、吸收、合理調節三者之間的關系。
            The four factors of polishing speed, amount of coating, pressure and drying temperature are mutually restrictive. According to the different surface of paper, the relationship among wetting, absorption and reasonable adjustment is discussed.
            5. 定期檢查紫外線干燥設備
            5. Regular inspection of ultraviolet drying equipment
            UV燈在UV干燥裝置中隨著使用時間的延長,有效功率逐漸降低,一般UV燈的有效時間為1000小時。生產中應定期檢測有效功率,當使用時間接近1000小時時更換有效功率。
            The effective power of the UV lamp in the UV drying device decreases gradually with the prolongation of the use time. The effective time of the general UV lamp is 1000 hours. Effective power should be periodically tested in production and replaced when used indirectly for nearly 1000 hours.
