Zink prints are designed to last a long time, but how long they actually last depends on a number of factors. One important factor is how the prints are stored. Zinc prints should be stored in a cool, dry place out of direct sunlight. If they are exposed to too much light or heat, the colors may fade over time. Another factor is whether the print has been coated with a protective varnish. Varnishing can help protect the print from fading and other damage. Finally, it is important to handle Zink prints carefully to avoid damaging them. With proper storage and handling, Zink prints can last for many years. However, if you want your prints to last a lifetime, it is best to have them professionally framed. Framing will help protect the print from damage and extend its life.
