Visual assessment

Microscopy:

WhatTo visualise certain aspects of the substrate a stereo microscope is in place (up till and including enlargement of 165 times). Light sources available are direct -and chafing light.
WhyTo look into reasons causing e.g. piling, printing disturbance, surface pollution, crease problems etc. To illustrate we can make a photograph with a Canon SC30 digital camera, mounted on top of the microscope.

Docucenter:

WhatTo visualise certain aspects of the substrate a Docucenter is in place (up till and including enlargement factor 8) Light sources available are chafing light, transmitted light, direct light in D50, D65, UV, infra-red and fluorescent light and optional use of several filters (different wavelengths)
WhyTo look into reasons causing e.g. piling, printing disturbance, surface pollution, crease problems etc.; to show surface differences (e.g. roughness), to show sheet formation (cloudiness) or safety elements like watermarks, holographic features, filaments. To illustrate we can make a photograph with a built-in camera with split screen possibilities.

Light booth:

WhatTo quickly check certain aspects of the substrate or printing ink a light booth is in place, with light sources D65, D50, Tungsten and UV.
WhyTo check e.g. on OBA content or metamerism. Metamerism is the phenomenon that two objects under certain circumstances seem to have the same colour, whereas under different circumstances a difference in colour is visible. The spectra of two different light sources are metameric when the colour of those sources are the same to the human eye.
