The shelf life of silkscreening inks can vary depending on the specific type of ink and storage conditions. Generally, water-based inks can last anywhere from six months to a year when stored properly, while plastic inks may have a longer shelf life of up to two years. It is important to keep the inks in a cool, dry place, away from direct sunlight and extreme temperatures, as these factors can degrade the quality over time. It is also advisable to tightly seal the containers to prevent oxidation and contamination from moisture.
