Table 1
Scoring key for comparing the results of tape lifted and control halves on the ESDA lift.
| Score | Result |
| -2 | Significant improvement of/for the top (tape lifted) half relative to the lower (control) half |
| -1 | Marginal improvement of/for the top (tape lifted) half relative to the lower (control) half |
| 0 | No difference between the two halves |
| 1 | Marginal degradation of/for the top (tape lifted) half relative to the lower (control) half |
| 2 | Significant degradation of/for the top (tape lifted) half relative to the lower (control) half |
Figure 4
Images of the ESDA lifts of page 2, i.e., the page located directly under the original handwritten page. Here the difference between the two halves can be easily observed.
Figure 5
Image of the ESDA foils of page 3 in the stack. Here indentations can be seen on the lower half, but not on the top half.
Figure 6
Mirror image of the ESDA® foil of the reverse side of page 2, i.e., the page located directly beneath the original page.
Figure 7
Images of damage caused to the paper due to the tape lifting process (shown at 4x magnification). Here the top surface of the paper has been lifted and torn.
Figure 8
Image showing the effect of the tape lifting process on the paper fibers (at 8x magnification). In the upper half of the image (Section A) the paper has a mottled appearance whereas the fibers sit flat in the lower half of the image (Section B).
Figure 9
These images depict the differences observed in the indentations in office paper under oblique light (at 2x magnification). The image on the left is the tape lifted half and the image on the right is the control half.
Figure 10
These images depict the differences observed in the indentations in notepaper under oblique light (at 2x magnification). The image on the left is the tape lifted half and the image on the right is the control half.
