Offset Ink Proofer SEMY-225
The Ink Proofer is one of the core products of Senming Equipment, specifically designed for the printing, packaging, advertising design, and ink R&D industries. It precisely simulates the color rendering effects of ink on different substrates to ensure color consistency. Through a standardized proofing process, it helps users predict ink hue, optimize production quality control, and reduce rework costs.
