Believe it or not sometimes WD-40 will lift out ink.... try it in s small place then wash with mild detergent.
I had a carpet cleaner tell me this when I asked him what was he using in the can that was covered with duct tape.... and also from the auto store, an engine cleaning product you spray on and rinse it quicklie... Yes, that was the 2 products he had tapped with the duct tape....I was so surprised and now when I have a stain I use it and it works!!!Especially if it is a petrolium based ink!! just try a small spot first... its worth a try than having to rid the quilt....
