In intaglio printing the pressure between the engraved cylinder and the paper is very high. From this the printed paper can have a certain deformation: the paper has been embossed. There can be a difference in embossing between types of paper and types of plastic film.
A printing disc with a certain groove in it is rolled off against the substrate under standard conditions. The embossing is measured with a profile measurement system
Method of operation
• It is recommended to execute the test in the standard atmosphere; to most standards it is 23.0 ± 1.0 °C (73.4 ± 1.8 °F) and 50 ± 2% rh.
• For the operation of the AIC2-5T2000 and Global Standard Tester follow the instructions of the manuals, IGT information leaflet W100 and the displays accurately.
• Handle the samples carefully.
