Abstract
Nonlinear transformation technological opportunities of hand-written documents' image brightness are investigated. It is shown that such transformation with use of computer allows to differentiate the initial text from forged fragment. The phenomenological treatment of virtual solarization effect and artifacts is offered. Utility of an applied graphics standard program package is appreciated. The original software is described.
