Abstract
Traditional methods used for paper surface characterization, such as smoothness, roughness or porosity determination, generally do not enable objective and accurate analysis. An appropriate measuring technique has to be direct and at the same time extremely precise, as it should provide quick and accurate characterization in micrometer measuring area while analyzing large sample area (minimum 10 cm in x-y direction) and its depth (100 microns in z- direction). Microscopic methods tested so far are limited primarily by their low surface area that can be analyzed while profilometric techniques suffer from limited sensitivity and have problems analyzing extreme samples (sensitive coatings, very rough papers, etc.).Basic goal of our project is development of the method, which will enable quick and efficient surface analysis, primarily determination of smoothness, roughness, micro/macro porosity, gloss non-uniformity and other undesirable phenomena, having especially detrimental effects in printing. Sample preparation should also not be too much time consuming. Apart from the established indirect air-flow measuring methods, newer techniques will be tested and developed based on microscopy, profilometry and interferometry.
