Setting, or curing, ink is a critical step to ensure it dries properly, adheres to the surface, and becomes durable. The method required to set ink is not universal; it depends entirely on the type of ink and the material (substrate) it is applied to.
All inks need to be set or cured in some form to achieve their final properties. This process transforms the liquid ink into a solid state, fixing it permanently onto the surface.
Common Ink Setting Methods
Based on different ink types and applications, various setting methods are used. Here are some examples:
- Heat Curing: Required for certain fabric inks.
- Air Drying: Suitable for inks on specific non-porous surfaces.
- Kiln Firing: Necessary for ceramic inks.
- UV Curing: Often used for solvent-based inks.
Let's look at the specific examples mentioned in the provided information:
Specific Examples of Ink Setting
| Ink Type | Substrate | Setting Method | Details/Conditions |
|---|---|---|---|
| Water based Aquatex Fabric inks | Fabric | Heat | Requires the application of heat. |
| Aqua inks | Metal/Plastic | Air Dry | Dries naturally over time. |
| Ceramic inks | Ceramic | Kiln Firing | Must be fired in a high-temperature kiln. |
| Solvent inks | Various (often non-porous) | U.V. Flash Curing | Typically requires exposure to UV light. |
As highlighted, water based Aquatex Fabric inks require heat for setting. Other inks have different requirements, such as air drying (like Aqua inks for metal/plastic, which air dry in 48 hours), firing in a kiln (for ceramic inks), or UV flash curing (generally for solvent inks).
Choosing the correct setting method is crucial for the longevity and appearance of the printed design. Using the wrong method may result in the ink not curing properly, leading to smudging, poor adhesion, or lack of durability.
