Water-Based Color Concentrates 
Water-based color concentrates are supplied for use in dispensing and dosing systems, allowing the required color to be prepared and adjusted.
Water-Based Ink Additives 
Water-based ink additives are used to adjust ink performance and improve final print quality. The dosage of each additive should be determined according to the ink type, printing press conditions, and desired result.
| Additive Name | Maximum Addition Rate | Application and Usage Notes |
|---|---|---|
| Defoamer | 1% | Helps prevent foaming in the product. Exceeding the recommended dosage may cause tiny bubbles on the printed surface. |
| Abrasion Resistance Improver | 10% | Improves abrasion resistance of the printed surface. Exceeding the recommended dosage may reduce gloss and produce a matte finish. |
| Drying Retarder | 10% | Helps prevent the ink from drying too quickly when printing with high-line-count anilox rollers. |
| pH Adjuster | 1.5% | Used to bring ink pH into the desired range and should be added in a controlled manner. Excessive use may affect the ink formulation and structure. |
Water-Based Overprint Varnish (OPV) 
Water-based overprint varnish (OPV) is used to protect the printed surface and enhance its gloss.
Choosing the Right Product
Selecting the right water-based ink requires considering the substrate, printing press specifications, anilox type, printing speed, and expected resistance properties together.
SunColour specialists are available to provide consultation and technical support for product selection and optimizing printing conditions.
