Screen printing inks vary by type, and their safety depends on the specific formulation: Plastisol inks do not contain solvents but can contain PVC and plasticizers. They are safe to handle but must be properly cured and disposed of. Water-based inks are generally low-hazard and eco-friendly, though some pigments may require protective handling. UV-curable inks are more sensitive; uncured UV components can be irritating to skin or eyes. Overall, screen printing inks are not considered dangerously hazardous when standard safety practices are followed—such as wearing gloves, ensuring good ventilation, and proper curing to avoid exposure to uncured chemicals.
Water-based inks reduce harmful solvents and VOC emissions, offering a safer and more sustainable alternative to traditional plastisol inks. They are easy to clean, biodegradable, and compatible with various textiles, making them ideal for eco-conscious screen printing.
Modern reclaiming solutions, degreasers, and stencil removers are formulated to be biodegradable and low-toxicity. Using these chemicals minimizes environmental impact while maintaining high-quality screen preparation and cleaning results.
Switching to PVC-free and phthalate-free plastisol inks eliminates chlorine-based chemicals and harmful plasticizers. This reduces environmental hazards and ensures safer products for consumers without compromising print durability.
Using LED UV exposure units, energy-efficient flash dryers, and optimized curing systems reduces power consumption and environmental footprint. Efficient equipment also lowers production costs and contributes to sustainable printing operations.
Eco-friendly screen printing is not only about inks and chemicals—it also requires responsible disposal. Collecting chemical waste, filtering solids, and complying with local environmental regulations ensures that water and soil are not contaminated, supporting overall sustainability.
