喷墨应用包括小型办公室和家庭打印机（SOHO），用于广告和图形艺术的大型打印机，以及用于标记，编码和标记的大批量工业打印机。喷墨墨水的着色剂必须满足严格的质量标准。墨水可以在墨盒中储存几个月，然后在热或机械应力下通过微小的敏感喷嘴，以形成限定尺寸和形状的液滴。主要要求是：
- High surface tension to provide reliable droplet formation and ink flow
- Low viscosity for consistent ink flow
- 优异的过热性降至0.2μm过滤孔
- Extremely low salt content to protect printer heads and nozzles from corrosion
- 缺乏二价阳离子和重金属，用于长期储存稳定性
除了打印过程之外，着色剂是打印和图像耐用性的必要因素，并且必须提供：
- 可见光和紫外线辐射的牢度
- 臭氧和其他氧化空气污染物的牢度
- Fastness to humidity and mechanical abrasion
文具通常包括写作所需的所有物品。典型的应用程序正在为日常使用写作器具，例如钢笔，圆珠笔，铅笔，毡尖笔和FineLiner钢笔。其他物品更有可能在办公室中找到，例如亮点，白板标记，永久性和非永久性标记以及邮票垫。文具着色剂的许多质量要求与喷墨应用和需求类似的性质和质量标准非常相似。此外，写作器具和印章垫需要为特殊墨水系统显示特殊功能，例如防伪油墨，隐形油墨和可擦除墨水。具体要求是：
- High color strength, especially for black and blue inks
- 全球遵守环境安全产品的规定以及缺乏敏感的副产品
- High surface tension and low viscosity for consistent ink flow
