In today's metal signs or non-metallic standard plate screen printing, more printing ink can be used, but it is not easy to choose the suitable ink (coating). The commonly used inks for signboard screen printing are as follows:
1、烘烤瓷漆：
1. Baking enamel:
是一種單液型配方，當受熱時發生交聯，存儲性能較好?？纱娣?個月一年。具有良好的光潔度，耐磨、耐化學和耐候性能，因而使用普遍。醇酸、丙烯酸和聚酯具有這些特性。環氧樹脂有斷裂和粉化的傾向，一般不在戶外使用，但它干燥快，有良好的耐化學腐蝕特性。醇酸瓷漆具有平衡的物理特性，如耐化學性和耐候性、可成形性、硬度和光澤，被廣泛地使用著。
It is a kind of single liquid formula. It crosslinks when heated and has good storage performance. It can be stored for 6 months to one year. It has good finish, wear resistance, chemical resistance and weather resistance, so it is widely used. Alkyd, acrylic and polyester have these properties. Epoxy resin has the tendency of fracture and pulverization, which is not used outdoors, but it dries quickly and has good chemical resistance. Alkyd enamels are most widely used for their balanced physical properties, such as chemical and weather resistance, formability, hardness and gloss.
2、空氣干燥瓷漆：
2. Air drying enamel:
常用醉酸制成，得用空氣中的氧氣，經過反應實現固化。醉酸瓷漆的性能由使用油的類型和數量而定。油干燥時間越長，瓷漆的干燥時間就長。當以干燥速度為條件時，干燥時間長的油漆一般都有良好的表面耐用性能。這些漆多用于室外金屬標識牌。
It is usually made of drunken acid, which needs oxygen in the air to realize solidification through reaction. The performance of acid enamel depends on the type and quantity of oil used. The longer the oil drying time, the longer the enamel drying time. When the drying rate is taken as the condition, the paint with long drying time generally has good surface durability. These paints are mostly used for outdoor metal signs.
3、溶化揮發油墨：
3. Dissolving volatile ink:
只依靠溶劑揮發以實現干燥。涂層終的性能根據配制成液體之前聚合物中所固有的物質性能定。此類聚合物中含有熱塑性丙烯酸。以揮以性為主份的絲網印刷油墨通常會常受到溶解的損害。有一些不溶于汽油和酒精的丙烯酸，其中膜面可與接觸，因而，以熱塑性丙烯酸、乙烯和其它可溶的聚合物為主份的油墨大多用在塑料基材上。
Drying is achieved only by solvent evaporation. The final performance of the coating depends on the properties of the material inherent in the polymer before it is formulated into a liquid. These polymers contain thermoplastic acrylic acid. The volatile silk screen printing ink is usually damaged by dissolution. There are some acrylic acid which is insoluble in gasoline and alcohol, and the film surface can be contacted. Therefore, the ink mainly composed of thermoplastic acrylic acid, ethylene and other soluble polymers is mostly used on plastic substrate.
4、雙液型油墨：
4. Double liquid ink:
常見的是環氧樹脂或聚氨酯，盡管還有其它許多種。經常在材用的雙液系統是節省能源的明智的選擇，其涂層質量高，但混合不方便。此外也要要根據產品的用途來選擇，如果產品可能用在戶外，而且還要注有某些柔性，那么選用以脂肪族烴為主體氨基甲酸乙酯油墨。雙液型環氧樹脂油墨與烘烤型瓷漆的使用性能相同，但成形性不夠好。
The common ones are epoxy or polyurethane, although there are many others. The dual liquid system, which is often used in wood, is the most sensible choice for energy saving. Its coating quality is high, but the mixing is not convenient. In addition, we should also choose according to the use of the product, if the product may be used outdoors, but also note some flexibility, then choose aliphatic hydrocarbon as the main body of ethyl carbamate ink. The performance of double liquid epoxy resin ink is the same as that of baking enamel, but the formability is not good enough.
5、油墨添加劑：
5. Ink additives:
與其他油墨一樣，金屬用絲網印刷油墨也含有添加劑，這是生產時中進的少量化學劑，以改善墨膜的性能，有些能加速固化或引發固化，而另一些可使氣泡破裂、墨質均勻，減少結膜可能性。生產廠家根據具體的配方交添加劑與油墨混合在一起，印刷者所需的是將油墨調稀適合印刷的稠度。
Like other inks, metal screen printing inks also contain additives, which are a small amount of chemicals introduced in the production process to improve the performance of the ink film. Some can accelerate the curing or initiate the curing, while others can break the bubbles and make the ink quality uniform, reducing the possibility of conjunctiva. According to the manufacturer's specific formula, the additive is mixed with the ink. What the printer needs is to dilute the ink to the consistency suitable for printing.
