Dugraf Form Rollers
Greater cost-effectiveness, durability, and print quality for your process Dry Offset
DUGRAF Form Rollers are designed for consistent ink transfer, operational stability, and high performance in industrial metal printing applications.
-
In Dry Offset printing, the consistency of ink transfer directly affects the quality, productivity, and final cost of the operation.
DUGRAF Form Rollers were developed to deliver consistent performance in demanding industrial processes, contributing to sharper image definition, greater print uniformity, and fewer adjustments required during production.
Made of polyurethane (PU), these rollers combine durability, stability, and precision to meet the demands of high-speed and metal printing applications.
-
Cost-effectiveness
The roller's performance should be evaluated in addition to its purchase price.
Properly specified form rollers help reduce downtime, adjustments, waste, and replacement frequency, thereby improving the total cost of operation.
Durability
With elastomeric properties designed to provide mechanical strength and wear resistance, DUGRAF Form Rollers were developed to withstand demanding production cycles.
Print quality
The continuous transfer of ink contributes to greater density stability, uniformity of solids, color accuracy, and improved definition in printed materials.
Faster cleaning
The uniform roughness and controlled finish facilitate cleaning during shift changes, reducing setup time.
Customization
Sizes are 100% customizable based on demand, equipment, and specific application scenarios.
