SJH water-based glow ink glows in the dark test: eco-friendly water-based system that keeps glowing in the dark - for kids products, toys, safety signs and creative items.
A full written description of the demonstration, so the content is readable without playing the video.
This video demonstrates SJH water-based glow ink: an eco-friendly water-based system that keeps glowing in the dark - for kids products, toys and safety signage.
The video shows the printing behaviour of water-based glow ink. Water-based systems use water as the dispersion medium, with markedly lower VOC content than solvent-based inks, low odour and a friendlier profile for operators - and better compliance with the environmental expectations for kids products and indoor items. This is the main reason to choose the water-based route.
The camera switches to a dark environment; the pattern begins to glow and shows its afterglow decay. The content and dispersion state of the phosphorescent pigment in a water-based system directly affect glow brightness; compared with solvent-based, brightness is usually somewhat lower, but for kids products and toys, environmental and safety priorities outweigh maximum brightness.
The video helps explain substrate suitability. Water-based inks perform better on absorbent stocks (paper, card) and need matching surface treatment or a dedicated formula on non-absorbent plastics to ensure adhesion and drying. Specify the substrate type and the actual use scenario so the right water-based system can be matched.
| System | Water-based dispersion, low VOC and low odour - better environmentally than solvent-based |
|---|---|
| Glow | Keeps glowing in the dark; brightness usually slightly below an equivalent solvent-based system |
| Substrates | Best on absorbent stocks; plastics need surface treatment or a dedicated formula |
| Typical use | Kids products, toys, indoor safety signage, eco packaging, creative items |
Water-based glow ink is the environmental-first choice: in kids products, toys and indoor signage - where people touch the product or spend long periods indoors - low VOC and low odour are often worth more than a small loss in brightness. Where brightness is a hard requirement (for example fire evacuation signage), a high-brightness solvent-based or purpose-matched system is preferable; we can advise by actual application.
