Part 1.
Since writing the article in WW1 Aero, No129, August 1990, the data has been revised, and a "new" five color upper day pattern was discovered. This new pattern has values and colors close the the upper 4 color pattern. So what now have in the German printed fabrics is:
1.Five color upper day pattern very dark.
2.Five color upper day pattern dark.
3.Five color lower day pattern.
4.Five color overall night pattern.
5.Four color upper day pattern.
6.Four color lower day pattern.
7.Three color Naval printed fabrics.
On several different aircraft in 1917, the Item 3, five color lower pattern fabric was used as a top fabric with plain unprinted linen used on the under surfaces. The Item 1 was used by Pfalz Flugzeugwerke as a top fabric on the Pfalz D.IIIa, D.VIII and the D.XII. In some instances plain unprinted fabric was used on the undersurface.
Item 2 above, was used on most aircraft in 1918 as a top fabric with item 3 lower printed fabric.
During my study of fabric sample from German aircraft, I found the fabric distorted, so I measured fabric samples loaned to me. Prior to any measurement being made I squared the sample on my drawing table to put the fabric sampled into the condition as it was when woven and printed. The purpose was to ensure the shape and location of the polygons were correct.
I made 1/12.5 scale patterns and full size patterns of the four and five color patterns. The polygons on the five color pattern were identified A through E,and 1 through 4 on the four color pattern.
