Thanks for the image and the exact measures;
so, here is the issue:
- your image (scan) size is: 3000 x 674 pixels ==> the aspect ratio of your Label image is: 3000 / 674 = 4.45
- your measures (228.6 x 50.8 mm) however indicate a different aspect ratio of you Label: 228.6 / 50.8 = 4.5
The different aspect ratio will make the Target Manager reject your image, when you try to upload it, as it is geometrically inconsistent with the real shape.
Now, it could be that your real measures are exact but the image (in pixels) is somewhat vertically stretched, or maybe missing some part (e.g. have you cut away some part of the original label when unwrapping it from the bottle ?)
Or, vice versa, it could be that your image scan is correct, but for some reasons your bottle measures are incorrect.
So, whichever is the error (real bottle measures or image scan), you need to make your image consistent with your expected dimensions, so that the aspect ratio matches (must be one of 4.5 or 4.45 for both the image and the real label)
For example, I was able to upload your image JPEG successfully, by correcting the dimensions as follows:
Your measured width: 228.6 ==> Corrected Width: = 50.8 (height) x 4.45 (instead of 4.5) = 226.06 (instead of 228.6)
Then I entered these values in the Target Manager:
- Height: 50.8
- Diameter = 226.06 / PI = 71.957
And this worked flawlessly, see attached image.
