[Hidden-tech] Question about Image Quality

Hi Chris,

Interesting dilemma.
I think it might depend upon how transparent the paper is, and how dark the ink is. The black card would still be an improvement, unless the ink bled through. Maybe you can also adjust the contrast of the scan so the writing from the back is less noticeable? 
Or experiment with a backing card the same color as the ink on the backside?

Let us know what worked the best.

Best,
Kimo

But since sometimes we don't live in an ideal world, I have had passable results from scanning a printed image at a really high resolution so that I can do some image correcting or color balancing in photoshop and then reduce the resolution to make a more reasonable file size.
