It can enhance the resistance of ink to chemical and mechanical contact. However, it should be noted that the ink should be printed within 8 to 16 hours after the hardener is added. H1 will not make the ink yellow. It has a relatively flexible ink layer, long shelf life and slow drying, so it is suitable for outdoor use. H2 will form a hard and tough ink layer, It is fast drying and has a shorter shelf life than H1. H2 will turn yellow when exposed to UV radiation (outdoor use), and can show colors like varnish, white or other light colors mixed with white
