This special engraving type and specification delivers a high opacity white, while ensuring a smooth laydown due to eCell digitally generated cell configuration and advanced transfer properties.
A simple method is to take a printed white sample, place this over a calibrated black Leneta board, and measure the density of black through the white printed sample.
This is the simplest way to judge or compare before-and-after samples. Of course, there are more advanced scientific methods that can also be used in the field.
If we compare the visual samples in the image at the top of the page we can see a massive improvement with regards to transfer, density and opacity on Bopp Film. The image on the left shows the results from a conventional 60 degree Anilox (100L/cm @18,00 cm | 3m2 vol.), while the image on the right shows the results from an eCell (HD) HDLE White Anilox (110L/cm @ 16,30cm 3m2 vol.)
It’s also important to note that this has been achieved using a lower ink volume cell capacity, and ink viscosity.
“We have had many customers from around the world requesting an Anilox with the ability to produce a high density, low viscosity opaque white on various films,” says Paul Rich, CAE’s Technical Director.
“We have seen a good white makes a substantial difference to final print results, and our eCell for white has helped many customers meet this requirement with their preferred ink suppliers.”
