Printing German WW1 Lozenge Camouflage onto Tissue
by Bill Brown
It all started when my flying mate, Pete Iliffe, built a Siemens Schuckert DIII.
He came round one Saturday afternoon and asked if I would draw him a template on my computer
for masking his wings so that he could spray the lozenge pattern. ‘No problem’ sez I
(mouth open - brain off) and some time later it was done, and Pete said ‘Great, do me
five copies. After that it was all my own fault!
I said ‘Why don’t we colour it in and see what it looks like?’ So we did and
printed it out, changed the colours, printed it again, changed the colours, etc., etc.,
etc., until we finally ended up with something we both liked.
Then we decided to print it onto tissue to see what it came out like. When
Pete saw it he wet himself with excitement and all thoughts of spraying went out of
the window, and the phone was ringing! Pete’s wife wanted to know where the **** he was
and didn’t he know the supermarket was closed in an hour and if he wanted food next week
he’d better move his backside, quick! Of course we’d only done the upper surface colours,
so the next day we went through it all again with the under surface colours.
That got Iffy off my back for a while so I decided to have a go at the naval
lozenge pattern, which is all hexagons - easy on Autocad. That turned out OK so I built
a peanut scale Zeppelin (Dornier) floatplane so that I could use it.
Things quietened down for a while then, but not for long. Albatros published
their Fokker D VI Datafile, Iffy’s favourite plane!
This one needed the four colour pattern. Here we go again!
How it Was Done
I have a book on the restoration of an Albatros D Va which contains an accurate drawing of
the five colour lozenge pattern (they actually had some rolls of cloth screen printed in
Germany). This was plotted in Autocad using X & Y co-ordinates. A separate layer was created
for each of the five colours. In Autocad these layers can be turned on and off.
One drawback in using Autocad in this application is that the colour palette is
limited to 256 colours, so we had to experiment with those available to give the
best effect. The chosen colours were then applied to the individual lozenges. This
basic pattern was then repeated until we had suitable length for printing. This was
then copied, turned upside down and placed next to the original length, this being
the way the original cloth was used. This double width was then repeated until we had
enough width to fit the printing area. The next step was to turn off the layer containing
the pattern drawing leaving the coloured lozenges, otherwise it would have printed with a
black outline to all the lozenges, definitely not scale! The big advantage of doing this
in Autocad is that it can be accurately scaled to any size without loss of quality.
If you want a scale of 1:37.2 you can have it - spot on.
The next job is to print it onto the tissue. I used Jap tissue and printed it
onto the matt side, but first you have to attach it to a support sheet. There have been
several ways of doing this published, but the way I prefer is as follows. Take a sheet of
ordinary A4 paper and lightly spray around the edges with Spraymount. Tape your tissue,
shiny side up, to a flat surface, stretching out all the wrinkles. Lay the A4 sheet onto
the tissue and lightly press into place. Now trim the tissue to the A4 sheet leaving about
3mm proud at one end only. This the trailing edge of the sheet when inserted into the
printer. The printer should be set to print at 1200dpi on normal paper, which gives the
best results. When printed remove the tissue immediately by peeling the proud edge back
on itself. You should now have a sheet of lozenge tissue, but there is a very important
fact to bear in mind when using it. The ink is NOT waterproof! You can attach the tissue
using dope or paste, or you can use my favourite method which UHU Pen adhesive, which
comes in a tubular container with a gauze pad at the end, which you wipe around the
framework to be covered. The adhesive is a gum, which grabs but allows plenty of time
for stretching out wrinkles. Once firmly attached and trimmed the tissue will need
shrinking, and the only way to do this is by lightly steaming. With Jap tissue I have
found this to be quite adequate. The ink is impervious to dope so you can carry on as
normal from this point.
The zip files at the link below below contain 1/24 scale lozenge patterns in .dxf format which will print
out on A4 size sheets and also a new set of revised 5 colour patterns in pdf format.

As well as Bill's dxf and pdf files, I am pleased to say that the page linked above will also allow you to download
a new set of JPEG files for sheets of 4 and 5 colour lozenge created by Rich Weber. These will
be useful for those who have trouble reading and manipulating DXF files.
Please note that these files are placed here free of charge for the benefit of the scale model community so please don't use them for commercial purposes.
