[Health-related requirements for the print design of illustrated texts in publications intended for children].
The fact that there are essential differences in the volumes of texts for continuous reading in the belles-lettres and those for episodic reading (encyclopaedias, comic books, etc.) and marked differences in the area of the type pages intended for illustrations made it necessary to substantiate differential requirements for these groups of publications. Hygienic requirements were corrected by using the data obtained from 150 experiments covering 36 secondary-form pupils. Based on the well-known data on temporary visual fatigue thresholds (TVFT) and on the experimental findings, the authors defined the ratio of higher TVFT to the actual time of reading the texts of different volumes. A complex of print design indices to be hygienically regulated varies with the multiplicity that is in fact a safety factor.
