What makes UV-curable inkjet technology a good fit for Label Printing?
This blog is the first of a three-part series discussing the positive attributes of UV-curable ink technologies as presented in a panel discussion at IT Strategies’ Digital Packaging Summit by Mike Barry, Fujifilm Product Marketing Manager – Digital Solutions.
How does UV-curable inkjet technology work?
The basic make-up of UV-curable inks consists of four components: monomers, oligomers, pigments and photoinitiators.
The monomers provide a building block of the ink and can contribute certain properties such as softness/hardness of the ink when cured as well as flexibility or elongation characteristics of the ink for varying types of applications. Monomers also help control ink viscosity which is essential to jetting reliability.
The oligomers in the ink formulation consist of reactive resins and uniquely formulated adhesive components for printing on particular substrates.
The pigments provide the color. However, the pigment dispersion is a critical component of the UV ink make-up as the particles need to be ground to less than 200 nanometers (one-fifth the size of a human nerve cell process) to fully develop color, with each nano particle coated to prevent agglomeration (clotting). Particles that are too large or agglomerated would compromise jetting accuracy, resulting in unacceptable print quality. Essentially all inkjet inks, whether UV or aqueous, need to be nano-sized to jet reliably and provide precise drop placement to optimize print quality.
“The R&D and quality control in the manufacturing of inkjet ink is crucial to achieve the incredible color consistency and print quality delivered by today’s digital presses.” […]
A recent article by IT Strategies consultant Marco Boer in Printing Impressions (“Marco Boer Forecasts Growth for Production Inkjet Printing Market”, Printing Impressions, March 22, 2017) firmly establishes production inkjet as a viable printing tool for any printer interested in profitable growth.
“Inkjet technology co-exists with other printing technologies, but […]
InfoTrends author Frank Romano showcased recently in an article (The Next Big Thing, InfoTrends InfoBlog, November, 2016) how the existing wide format inkjet technology in most print shops opens the doors for PSPs to participate in a new and growing category: Industrial Printing. The ability of flatbed UV presses […]
