Hi Paul,
The black colouration from news ink is composed of fine carbon granules. It can be fairly easily removed with Prochem A217 Ultrapac Renovate., subject to the usual pre-testing. An acid rinse would be advisable due to the cotton content.
On the micro-splitting front, I imagine that Solutions Eco Spotter would be effective also, though I have yet to try it on this soiling. Try this first, agitating with cotton towel, as if effective, no neutralisation will be required.
