Producing 127 backing paper from 120 backing paper

Dimensions

The backing paper for using with a 127 spool and film can be cut down from 120 backing paper. 127 backing paper is smaller both in width and length. The dimensions for different makes of backing paper varies slightly. Try and choose a 120 backing paper that has light annotation. Examples of this type of paper are Kodak Portra and Ilford FP4 Plus.

Nominal Values are:-

  • 120 Backing Paper:-
    Width: 62mm; Length 1430mm
  • 127 Backing Paper:-
    Width 47mm; Length 1090mm

At each end of the 127 paper there is a tab and taper. The tab is 15mm x 15mm. The taper covers another 15mm. These are included in the overall dimensions above. Now cut the 120 paper to 127 size. Accuracy is important because if the backing is too narrow your images are prone to light leaks, if the paper is too wide then it won't roll properly on to the spool. Roll the backing paper neatly onto a 127 spool to check the dimensions of the new backing paper. Adjust if necessary.

Annotation

After cutting the 120 paper to size, you need to annotate the paper with guidelines for where the film attatches and the numbers that are seen through the red window.

Measuring from the start end of the paper make the following marks using something like a Sharpie or some other quick drying permanent marker. Do not use Biro as it takes too long to dry. If the ink is not perfectly dry it will transfer to the film when rolled.

Part of Finished Backing

Measure the distance between 'Start' line and the 'End' line. This is the length of film required. It will be about 61cm. Roll the backing paper neatly onto a 127 spool. Run the backing paper through the camera to check the position of the annotation.

Job Done

Now source some 127 film.
