Lozenge decal test it for all

The piece on the left is external, the right side is internal.
It has less yellowing, possibly from lack of dope/varnish or age and exposure.
It has the "stained glass" look very prominently.
If I lose this it's because of a scheduled power outage.

I will close as the time approaches fast!

I have asked on another thread about the "stained glass" look, I don't believe that there was an answer. That image was off of ebay and I had never noticed this effect before.

I believe that the colors were very bright. I will have to go through my files and post it here.

Hello Gary Sewall,

Sorry about that!
I was in a hurry when I was creating this. I was editing and saving as fast as I could! Then repeating that process until I lost my connection. We were scheduled for a power outage from 10:00 P.M. to 4:00 A.M., but we were deceived.... Our power was not interrupted, but internet connectivity was within minutes of 10:00!
A lot of that has happened lately, whether it's due to the phone company tearing up the ground on our property recently while they lay fiber optic lines up and down our road or not. Any way it's very annoying!

Hi Doug,

I will do a search for images of original Flugzeugstoff. I don't have unlimited access to the internet and as I previously stated that it doesn't always work lately.

Keep up the good work, Jay

Hi Gary,

Thank you for posting the pictures of your fabric again. I can see almost the whole pattern, so the fabric was not cut lengthwise in production. For decals the spacing between seams is what we want. The part of the pattern hidden in the seam (10 - 20 mm on each side?) would not be seen.

We might be able to figure out how wide it was on the wing if we knew the rib spacing in the area of the cross. We could compare this to the spacing of the rib tapes to account for any shrinking since being removed from the plane.

Hi,

I did losenge pattern in vector graphic programm. I based on colors used by Doug (upper side) and colors by Mike Miller (down side).

Files are ready to print in scale 1/48 and by 300 dpi.

BTW, I thing the biggest problem is - to get the same colours on screen and by printing.

Wow Wojtek and Doug!
What an incredible resource you have both created! At this rate, we will never mourn the lack of retail decals again!

Cheers,

Hugh

Here are two more photos with slightly different contrast of my 90 year old, 5-color UPPER surface lozenge fabric for study. Note, there are NO "stained-glass" lines around the TOPside surface lozenge patterns, but there ARE lines visible on the BACKside surface patterns in the second photo. Also, in the second photo of the fabric BACKside, note the slight yellowing stain patterns. These stains are actually made from the Fokker D.VII's "V"-pattern plywood leading edge material.

For study, the ribs are exactly 300mm apart, but the fabric shown has not been pulled fully outward to stretch the fabric completely out.

On the TOPside surface, 15mm rib tapes are cut from 5-color UPPER surface lozenge fabric, typical of Fokker-built D.VIIs.

Per request, here are fine samples of original 5-color UNDERsurface lozenge fabric with two kinds of rib tapes - salmon and blue. Note the 'correct' colors! The last photo is of the fabric's BACKside. Here again, just like on the UPPER surface lozenge fabric, we see no "stained-glass" line effect on the TOPside surface lozenge patterns, but we DO see a slight line effect on the BACKside patterns.

Note, these colors may be slightly faded with time now. Also, I don't see much evidence of the final yellowing varnish coat applied to these UNDERsurface artifacts, so I wonder, if it wasn't applied, was it because the UNDERsurface fabric simply wasn't as exposed to the environmental elements as the UPPER surface fabric? Hmm...

And so look graphic files after printing.

Short version
I calculate that the spacing between seams on the wing is 1270 mm or 50 in. and recommend this as the basis for scale calculations.

Long version feel free to skip to "Does it make sense"
I looked at the photo with the tape measure. Though I could not read the numbersat the rib tapes, I could see them. By counting from the known positions (0 and 47 in), I determined that the number at the right edge of the first rib tape was 7 and the number at the right edge of the last (5th) rib tape was 52. This made four rib spaces 52 in - 7 in = 45 in. Thanks to Gary we know that this should be 4 × 300 mm = 1200 mm = 47.244 in. on the wing. The seam spacing is about 47.375 in. Setting up a proportion and solving results in (47.244/45) × 47.375 = 49.74 in (1263 mm) seam spacing on the wing.

I also measured it in pixels. From the right edge of one seam to the right edge of the other is 534 pxl. From the right edge of the first rib tape to the right edge of the fifth is 504 pxl. As above this would be 1200 mm on the wing. Again setting up a proportion and solving results in (1200 mm/504 pxl) × 534 pxl = 1271 mm (50.06 in)

The results are fairly consistent. The second method is probably more reliable, so I would round them to 1270 mm and 50 in.

Does this makes sense.
The seams are about 10 mm wide flat feld seams. If we assume that 15 mm is lost on each side in seams, then we have 1350 mm - 30 mm = 1320 mm. This would indicate a 50 mm (1320 - 1270) or 3.8% shrinkage to the doped cloth. Is this reasonable?

Any comments are welcome.

Gary,
Thank you again for providing photos and information. If you look closely at the area of overlap between polygons on your cloth, you will see that it is darker than either of the polygons. This is what they are trying to represent with the stained glass effect. It is just being overdone.

Those overlapping areas are often too prominent. In reality they where not really visible, or better, they are only visible when a light field was printed over/later than a darker field. The sample with tapes is the Halberstadt with the Silberstreif-Thiemeyer-Replicas, the sample without is an original, stored in perfect conditions since 1918 and dope-less, of course.

thank to you all for the help lower 5 color test 1 soon and i printed mine off with card stock and look at it with a magnafing glass { i spell that wrong} and no pixalation looking good
