1 Royal Ulster Rifles Printed Shoulder Titles

[sccollins07]

Does anyone know what the regulations were concerning the shoulder titles and divisional insignia worn by the 1 RUR within the 6th airlanding brigade? Some of what I've read seems to suggest that when the titles were officially adopted after Oct '43 as black on rifle green they were issued as printed rather than embroidered titles, which also seems to fit with other 6th airborne units like 1canpara but I've found what seems to be examples of both versions with 1RUR. The colour of rifle green is also a bit unclear, I assume it is the dark evergreen like colour but titles have faded and show everything from dark green through grey/olive drab looking titles; examples attached. Thanks!
