Filtration in Graphics Ink Manufacturing

Optimize Filter Performance at Every Stage of Your Process to Deliver Products for High Quality Printing

Pigmented Inks

Our filters remove large particles and agglomerates and contribute to the mixing process assuring full dispersion of pigments. Filtration also prevents printhead clogging to deliver consistent, high-quality printing. 


Solvent-Based Inks

Critical Process Filtration products with multiple media materials are compatible with the production of non-aqueous, solvent-based inks. Our filters remove oversize particles and disperse colorants, so you deliver great printing results.


Dye-Based Inks

Print performance depends on dyes free of particles and organic contaminants. Our filters are used to remove undissolved dye components, gels and bacteria that may clog printheads.


UV Curable Inks

Our filters allow the production of consistent, high-quality inks with UV-curable elements. We work with you to choose the right media to manage system pressure drop so you can deliver bright, long-lasting images.

Quality Assurance and Standards

Critical Process Filtration filters are designed for use in cGMP compliant processes. Our state-of-the-art manufacturing facility and quality-management system both meet ISO 9001:2015 standards. Each operation from assembly and test to cleaning, drying, and packaging is done in appropriately rated clean rooms, and each filter is assigned a lot code to ensure the traceability of manufacturing data and materials. A sophisticated MRP system collects and processes real-time data from manufacturing centers and inspection points.
