Creating a Clean Slate - Addressing Metering Challenges of White Inks
All professional printers eventually come up against the metering challenges of white inks. Throughout the industry, white inks are notorious for being inconsistent and requiring frequent changing of doctor blades often. The longer a doctor blade lasts, the more expensive it is in many cases. Weighing the cost of a doctor blade vs. the cost of press downtime is as issue printers and coaters deal with constantly. The issue with metering white inks is actually a little more complicated than just buying the right blade.
GATHER PROFESSIONAL SUPPORT
First and foremost, ink, anilox, and doctor blade suppliers should all be consulted in a cooperative manner. When everyone knows the details of the scenario, a more comprehensive solution can be attained. Having end seal suppliers involved can also prove useful. Most people working in these industries are either printers themselves or have at least been involved in the print industry for some time - so they will most likely be able to relate to your specific challenges.
