Funnily enough I haven't built that many WW2 RAF fighters in standard camouflage, and those few I have "free-handed" with the airbrush. But with the sublime Tamiya Spitfire kit I decided to explore making camouflage masks. I scanned the colour A3 sheet provided with the kit then imported the image onto the Silhouette screen, starting with the wings:
I measured the distance from leading to trailing edge on the kit where the wing walk stripe goes, then scaled the image onscreen to match that distance (just draw a straight line the measured distance, rotate and move it over the wing image and drag that out to match the line size).
Once that was established it was very easy selecting the line "figure of eight" draw tool to (manually) trace the outline of the camouflage lines:
I had already put down a base coat of Ocean Grey so the masks for those areas were pulled off and carefully laid in place on the wings. It took no time at all to spray the Dark Green resulting in crisp lines when the masks were removed:
That was the easy bit done, then "3D fuselage would be a different matter. But first I decided to finish the upper and lower wings. Slight problem, unaccountable problem, with one roundel on which the blue lifted when the mask was removed, no idea why:
but the other was fine:
There was a potential problem with the under wings; the centre of the roundel coincides with a large fairing....."lump" to me, that no mask or decal for that matter is going to willingly conform to. I sliced around it carefully once the roundel mask was in place then used masking fluid to fill the gaps. Worked well enough:
Adventures with the fuselage: I wasn't sure of the best way to go about these masks - separate port and starboard ones or a one piece "wrap-over" one. Well after a few experiments the latter wasn't that practical. So I used the same technique as the wings - scanning, importing (and flipping one image), scaling, tracing:
which ended up something like:
(but this has now been revised and uploaded to this site.) Screenshots showing mask positions:
and after applying to the model, spraying and removing:
Drawing the fuselage masks involved a certain amount of trial and error, and there is still a little touch up to do but generally speaking it's been a successful exercise.
Please feel free to download the masks but please read the caveat with the masks.
When I do the fuselage and tail markings I'll add them to this thread.
