Paper topography and optical impression
emco IAS - Image Analysis System
All applications are based on the original algorithms of Dr. Praast. The image is obtained by the camera. The numerical results and the images are availible after seconds.
In addition to established products new evaluation methods for paper topography are developed in close collaboration with Dr. Hermann Praast and end users: greasiness/ calander mottling as well as marks of felt, wire and dandy roll.
The emco IAS Cocklingtester is used to determine local tensions (bubble content) and global tensions (waviness), which are permanently visible after wetting.
The emco IAS Scarredness Tester is used to determine and evaluate recessed areas in the paper which, as a result of the paper technology, influence the optical impression of the paper surface.
The emco IAS Press Marks Tester is the industry standard for detection and control of the embossing of cigarette papers.
The emco IAS Mottling Tester determines the optical inhomogeneity of printed and unprinted papers on an area of 30 mm x 30 mm. Mottling is the printing unevenness in solid tone areas.
The emco IAS Calender Blackening Tester is used to characterise the negative optical impression of SC papers caused by the supercalender.
The emco IAS Missing Dots Tester was designed to determine imperfections in halftone prints.
