Direct thickness measurement of doctor-bladed liquid film on gravure roll surface [PDF]

open access: yes, 2015
We provide experimental evidence that the liquid film remaining on a doctor-bladed gravure roll surface significantly influences the liquid transfer from the engraved roll surface to a moving substrate.

Use of the Vandercook Proof Press to Predict Rotogravure Print Quality [PDF]

open access: yes, 1970
The object of this thesis is to investigate a new idea in predicting printability for rotogravure printing. Present proof presses in the gravure industry are clumsy, expensive, and in most cases, impractical for regular use.

Printed dose-recording tag based on organic complementary circuits and ferroelectric nonvolatile memories. [PDF]

open access: yes, 2015
We have demonstrated a printed electronic tag that monitors time-integrated sensor signals and writes to nonvolatile memories for later readout. The tag is additively fabricated on flexible plastic foil and comprises a thermistor divider, complementary ...
