Analysing Inkjet Ink For Better Print
Peformance
Using the Mastersizer 2000 particle size analyser, an inkjet ink manufacturer has succeeded for the first time in monitoring particle size reduction throughout the entire milling process.
Using the Mastersizer 2000 particle size analyser, an inkjet ink manufacturer has succeeded for the first time in monitoring particle size reduction throughout the entire milling process That is according to Malvern Instruments, the manufacturer of the Mastersizer 2000, which is claimed to have a broad measurement range of 0.02 microns to 2000 microns

The company added that the analyser can measure the size of agglomerates and primary ink particles equally well, which also enables suspension stability to be investigated.
Pigment based ink jet inks are being used increasingly for applications where durability and moisture resistance are issues.
They are produced by milling pigment dispersions.
The final particles must be 200nm, or less, in order to avoid blockages at the print head, defect formation within the printed film and inconsistent colour densities, said Malvern.
Data from the Mastersizer 2000 clearly showed the break-up of aggregates that were present initially, and the exponential reduction of particle size in the mill.
Confirmation that the final material met the required specification was also provided.
Longer term particle size monitoring showed that over a period of three days, potentially problematic agglomerates were formed.
The Mastersizer 2000 is a fully automated, SOP-driven instrument designed for the rapid analysis of either wet or dry samples.
Its measurement range can be accessed without making changes to the optical system, said Malvern. Request a free brochure from Malvern Instruments ...
