Application of printed fabrics.

[Dan_San_Abbott]

Ladies and Gentlemen;
Steve Lawson and I have had a discussion of printed ribs tapes. Steve believes that dark rib tapes can be applied to the upper and lower surface of wings. I have stated the upper surfaces had the dark printed rib tapes and the under surface had light colored printed fabric rib tapes. Idflieg was very specific about what went were in the regard to the dark and light fabric, and I quote from Flugzeugmeisterie Adlershof document dated 21 April 1917, it states in the third paragraph:
"The dark colored printed fabric is for all upper wing surfaces of the aircraft, and the sides of the fuselage, on the contary, the light fabric isonly intended for under surface of the wings and the under surface of the fuselage."
The dark patterned rib tapes are for the upper surfaces and the light pattern rib tapes are only for the under surface of the wings (and tailplane).
Blue skies,
Dan-San
