On Board Printer Filtration

The digital print industry is driven by image quality and repeatability. Although most ink jet inks are filtered well during formulation, filtration on-board a digital printer is necessary to capture any degradation by-products, environmental contaminants and residual printer component debris.  Without removing these contaminants, print quality suffers and becomes unrepeatable leading to downtime and print defects. 

Filtration on-board a printer is most effective when two filters are used: a bulk filter followed by a last chance filter. The bulk filter has the capacity for high flow and retaining contaminants, and is commonly a self-contained, disposable capsule filter. The last chance filter is positioned very close to the ink jet printhead for point-of use filtration. Its purpose is to protect the printhead from contamination by debris, which can cause catastrophic failure.

Our filtration technology offers advancements which helps ink jet printer manufactures achieve repeatable print quality. With the wide variety of ink jet ink chemistries used today, several different filtration technologies are available to achieve superior image quality. From next generation capsule filter designs to self contained filters developed for larger digital printing systems, our solutions provide the following benefits: 

• Enhanced image quality
• Reduced nozzle blockages and increased printer uptime
• Printing repeatability and consistency
• Reduced ink formulation costs     

Our solutions are suitable for the following applications: 

• Pigmented ink
• Dye based ink
• Solvent based ink
• UV curable ink
• Pigmented solvent-based ink
