水性油墨施工工艺流程
英文回答:
Water-based ink is a type of ink that uses water as its main solvent. It is widely used in various printing processes, such as flexographic printing, gravure printing, and offset printing. The construction process of water-based ink involves several steps.
Firstly, the ink needs to be prepared. This includes mixing the necessary pigments, binders, and additives together. The pigments give the ink its color, while the binders help to bind the pigments to the printing surface. Additives are also added to improve the ink's performance, such as its drying time and adhesion.
After the ink is prepared, it is then applied to the printing surface. This can be done through various methods, depending on the printing process used. In flexographic printing, for example, the ink is transferred to a printing
plate, which then transfers the ink to the substrate. In gravure printing, the ink is applied to the engraved cells on a cylinder, which is then transferred to the substrate. In offset printing, the ink is transferred from a rubber blanket to the substrate.
Once the ink is applied to the substrate, it needs to dry. This can be achieved through various drying methods, such as air drying, heat drying, or UV curing. The drying time can vary depending on the type of ink and the printing conditions. It is important to ensure that the ink is fully dried before further processing or handling to avoid smudging or smearing.
After the ink is dried, the printed material can undergo further processing, such as cutting, folding, or binding. The final product is then ready for distribution or use.

水性油墨是一种以水作为主要溶剂的油墨。它广泛应用于各种
印刷工艺,如柔性版印刷、凹版印刷和胶印。水性油墨的施工过程
涉及几个步骤。
首先,需要准备油墨。这包括将所需的颜料、粘合剂和添加剂
混合在一起。颜料赋予油墨颜色,而粘合剂有助于将颜料粘附在印
刷表面上。添加剂也被添加进去,以改善油墨的性能,如干燥时间
和附着力。
油墨准备好后,就需要将其涂在印刷表面上。这可以通过不同
的方法进行,具体取决于所使用的印刷工艺。例如,在柔性版印刷中,油墨被转移到印刷版上,然后再转移到基材上。在凹版印刷中,油墨被涂在刻有图案的圆筒上,然后再转移到基材上。在胶印中,
油墨从橡皮毯上转移到基材上。
油墨涂在基材上后,需要进行干燥。这可以通过不同的干燥方
法实现,如自然风干、热干燥或紫外线固化。干燥时间可能会因油
墨类型和印刷条件而有所不同。在进一步加工或处理之前,确保油
墨完全干燥非常重要,以避免污染或模糊。
油墨干燥后,印刷材料可以进行进一步加工,如切割、折叠或
装订。最终产品随后可以进行分发或使用。
