Colour reproduction analysis of portrait photography in cross-media system: image on the computer monitor–electrophotographic printing

Abstract

Photography is dominant illustration technique. Two-thirds of illustrations are realised in this technique most in commonly in the digital photography system. The portrait is one of the most present and most challenging photographic motifs which can be, in a technical sense, analysed primarily through monitoring of the changes in the skin colours. Modern publishing is characterised by increasing number of small circulations created in electrophotographic printing and, parallel, in electronic media. This paper deals with the portrait photography created on the computer monitor and with electrophotographic printing and the question if they can be, for consumers, considered to be the same. The evaluation was attended by the visual comparison based on the principle of memory harmonisation and ΔE₀₀ determination. The results point out satisfactory reproduction in the electrophotographic printing of colour portrait photography in comparison to the portrait defined on the computer monitor, although the reproduction results in colour changes for skin colours and primary and secondary colours of additive and subtractive synthesis.
