[split] Jorge's Retracer Thread: darker ink, retracing of text and drawings

[Jorge_Stolfi]

would you consider this evidence for MIO and against MRT if this defect follows the same distribution of ink shade variation as the main text?

I would have to look at that case and see whether it is indeed incompatible with MRT and/or supportive of MIO.

But, again, the evidence for MRT is not a single case of apparent retracing, or the mere existence of two or more shades of ink on a page.  Any such instance can be explained in several ways that do not require retracing.  It is the sheer number of such instances -- typically dozens on practically every page -- that makes MRT the simplest and most likely explanation.  

And then there is also the fact that, on almost every page, one can find text and parts of figure outlines that have faded to near invisibility.  How do you explain that other text or outlines on the same page, right next to those cases, is still dark and sharp?   A batch of defective ink could be the explanation if it happened on only a few pages.  But not on practically every one...

All the best, --stolfi
