However, if these come from a scanner, then the Brightness/Contrast control of the scanner software can often do a better job (because it has more data to work with). And if these receipts are shot with a smartphone, the better the shot (good an uniform lighting), the easier it is to work on (otherwise increasing contrast will also increase the defects) but the smartphone camera app may have some brightness/contrast control itself.
For more details, we need a sample receipt (or anonymized extract thereof).
Thanks for your response. I have several faded receipts (none of which is really confidential...there's just a bunch of them with varying levels of faded print, so hard to provide a one size fits all example), and I've tried the contrast / brightness scanner settings - contrast seems to work best, but the faint print on the receipts still doesn't always get picked up. I'll try taking a picture with my phone as you've suggested - it has a pretty good camera. Thanks again.
You can also try the Threshold tool, but a frequent result is that it threshold cracks, folds and spot in the paper at about the same time it thresholds faint print, so the result isn't always very readable.
