 Re: Shelf life for waterbased ink
To be honest I've never even considered scraping off the mould and using it anyway. I would with cheese, so I suppose it might be okay.
The shelf life of waterbased ink is generally measured in months. If it's not sealed properly I've seen it go mouldy in a shorter timeframe (weeks), and it can potentially last longer, but somewhere around one year is a good rule of thumb (for opened ink... I imagine unopened ink from the manufacturer could last longer).
