Sigma Eco is a premium ink roller manufactured by Katsura, designed to work with environmentally friendly inks (non-aromatic and vegetable oil-based) as well as conventional oil-based inks.
When using eco-friendly inks, traditional rubber roller often face challenges such as diameter shrinkage, frequent nip adjustments, and shorter lifespan. Sigma Eco is engineered to overcome and minimize these issues, ensuring your printing process remains smooth and efficient.
Maintains size and shape over time, reducing the need for constant adjustments.
Provides consistent performance and resists the formation of glazing on the roller surface, which can disrupt ink transfer and reduce print quality.
Generates minimal heat during high-speed operations, preventing premature wear.
Ensures consistent nip width and ink viscosity, guaranteeing stable print results.
Resistant to commonly used roller cleaning solutions, extending the roller's lifespan.
Upgrade to Sigma Eco and experience a more environmentally friendly and efficient printing solution without compromising quality.
The HW Series is designed for compatibility with vegetable oil-based inks as well as conventional oil-based inks. These roller enable printing with stable water width over extended periods.
Environmentally friendly inks often have detrimental impacts on rubber roller, such as insufficient water supply, diameter shrinkage, frequent nip adjustments, and shorter lifespan. The HW Series addresses these challenges with its superior features.
Reduces diameter shrinkage, nip width changes, and hardness variations, leading to longer lifespan.
Does not require water dial adjustments from morning to evening, as it can maintain water supply stability over long periods.
Capable of absorbing impacts against the plate cylinder when used as a form water roller.
Offers excellent tensile strength, enhancing durability.
Improves the effectiveness of dampening water usage.
Choose the HW Series for a more reliable and environmentally friendly printing solution without sacrificing quality and performance.
