Replace from step 9:
9) Paste the content of a clipboard: Edit - Paste.
10) Layer>Anchor Layer (Ctrl-H)
11) Layer>Duplicate layer (Ctrl-Shift-D) set to multiply
12) Export (no need to merge, this is done when you export).
But IMHO for strictly the same results (assuming you start from JPEG):
1) Select background
2) Edit>Clear [Del] (this replace the background by pure white)
3) Possibly duplicate/multiply
4) Export
However both techniques rely on the hypothesis that there exists a threshold level for "Select by color" where the whole background (white and see-through characters) is selected, without selecting anything in the good text. They can be improved by reducing th threshold and, after an initial simple click, shift-clicking in several places to add the missing bits. But there can be easier solutions, just post an image (or a representative extract) so that we can work on real data.
