New Uncoated UV Dataset and Profile
Printing United Alliance just released a new dataset and profile for UV curable inks on Uncoated paper, it’s called “Alliance_UC_UV”. This is significant as it fills a void in the current North American specifications. We currently have Character Reference Print Condition #3 (CRPC3), aka GRACoL2013UNC_CRPC3, which is for traditional solvent-based inks on Uncoated paper but there was no standard for UV Inks.
The difference in color gamut between traditional offset process printing inks and UV inks arises from their distinct formulations, drying mechanisms, and the way they interact with substrates. Here’s an overview:
1. Traditional Offset Process Printing Inks
- Drying Mechanism: These inks typically dry through absorption into the substrate and oxidation, which can limit the type of materials they are compatible with.
- Color Gamut:
- Traditional offset inks often have a narrower color gamut compared to UV inks.
- Absorption into porous substrates can cause slight dulling or loss of vibrancy, reducing the color intensity.
- The range of colors achievable may vary depending on the ink’s formulation and the substrate’s brightness or finish.
2. UV Printing Inks
- Drying Mechanism: UV inks dry or cure instantly upon exposure to ultraviolet light. This eliminates the need for absorption and allows the ink to sit on the surface of the substrate.
- Color Gamut:
- UV inks tend to have a wider color gamut due to their ability to remain on the surface of the substrate.
- Vibrancy and intensity are enhanced because there is minimal interaction with the substrate that could dilute or alter the pigments.
- The UV curing process also supports higher pigment loads, enabling richer and more saturated colors.
- UV inks can produce consistent results across a variety of substrates, including non-porous materials, which helps maintain a broader color range.
Key Takeaway:
- Traditional Offset Inks: Narrower gamut, more suited to paper substrates, and colors may lose some vibrancy due to absorption.
- UV Inks: Wider gamut, more vibrant and consistent colors, especially when printing on non-porous or coated substrates.
If maximizing the color gamut is a critical concern, UV printing often offers superior performance. Our parent company, Great Western Ink, makes both. Contact us for more information at: [email protected]
