Most of the sworls you will see are printed fabric.
I can't agree with this assertion. *The printed camouflage fabric was not used prior to the spring of 1918. *It was used only on Albatros D.III *of the later series 153 and series 253 and only in small batches averaging five to ten aircrafts.
There are exceptions as you have noted.
Many exceptions of well know aircrafts : Alb. D.III 53.27 flown by Fransz Gräser (Flik 42J) in october 1917, Alb. D.III 53.60 flown by Kurt Gruber (Flik 41J) in summer 1917, Alb. D.III 153.06 flown by
Godwin Brumowski (Flik 41J in august 1917, Alb. D.III 153.46 flown by Eugen Bönsch (Flik 51J in february 1918 and many others.
There are also examples of Alb DIII where an attempt is made to reproduce the printed pattern on some wooden parts of the airframe which are not fabric covered, notably the fin and fuselage spine. These vary in quality according to the ability of the painter and range from a close match to the cruder "sponging" already described. As most of these are field applications any "standard" is most unlikely IMO, and the sand or mustard yellow often quoted is as good an option as any assuming the availability of yellow pigment.
These references was given by Gotfried Banfield himself during an interview with Peter M. Grosz or Dr. Martin O' Connor (I can't find the reference now but I'm sure of this).
My main references on this subject are :
