When manufacturing camouflage sheets of substantial size, the camouflage pattern is normally printed or punched in repetitive consecutive steps so that a pattern repeat may be seen and impairs the camouflaging effect. The invention makes it possible to considerably increase the pattern repeat, i.e., the distance after which the pattern repeats itself on the sheet without increasing the size of the pattern, in that the sheet and the tool such as a printing plate are angularly displaced relative to one another in their own plane so that the pattern is repeated a number of times on the sheet such that adjacent areas of pattern are angularly displaced (turned) relative to one another. Thus, the pattern of each such area is in another angular position than the identical preceding pattern and the identical subsequent pattern.

DETAILED DESCRIPTION What I claim is: 1.
A method of manufacturing a camouflage sheet bearing an overall camouflage pattern composed of a plurality of contiguous component patterns having the general outline of a 3-, 4-, 6-, or 8-sided figure and each coextensive with a respective zone of the sheet, wherein the individual component patterns present the same irregular pattern features and the overall pattern is built up by separately applying the pattern features to the respective zones of the sheet and arranging for the pattern features of at least the majority of adjacent pairs of component patterns to be angularly offset relatively to one another by at least 45.
degree.
and at most 315.
degree.
.
2.
The method of claim 1, wherein the pattern element and the zones appurtenant thereto are square, immediately successive pattern elements being angularly displaced in relation to one another by 90.
degree.
or a multiple thereof.
3.
The method of claim 1, wherein the element intended for each zone has such patterning that at least a partial pattern match is effected between pattern elements occupying immediately successive zones.
4.
The method of claim 1, characterized in that every one of the several sheet portions is executed in the same shape as the zones and is furnished with its similar pattern element each and that these separate sheet portions are joined together and/or attached to a common under layer very close to one another with said mutual angular displacement to form the sheet thus composed of these sheet portions and, optionally, the underlayer.
5.
The method of claim 1, wherein the edges of the pattern elements are non-linear and have such shape that edge-matching is obtained between any of two successive zones, independent of their said mutual angular displacement.
6.
The method of claim 1, characterized by the steps of applying the pattern by means of a pattern template, and turning the pattern template and the sheet relative to one another after a zone is furnished with its pattern element and before the next zone is furnished with the same pattern element
