The best way to choose a white screen printing ink is to first decide what type of material you will be printing on. There are three main types of materials: fabric, paper, and plastic. Each type of material has its own unique benefits and drawbacks. Once you have decided on the material you will be printing on, the next step is to choose the right type of ink. There are two main types of inks: water-based and plastisol. Water-based inks are great for printing on fabric because they allow the fabric to breathe. Plastisol inks are ideal for printing on paper and plastic because they provide a durable, long-lasting print.
