Surface Preparation
I need to ink over a pencil sketch on gesso. When I did this before I found that ink would sometimes "spread' as the gesso is a bit absorbant. I do need the ink lines to show through the paint (hence the use of ink) Is there anything I can add to the gesso to make it a better surface for ink. Medium perhaps? or actual paint? I have also considered a fixative (spray) over the pencil, then a fixative again over the ink.
This is a bit of a difficult one - hopefully I've understood your question. From what you have said, you have prepared your piece with Gesso, and then created a pencil sketch on this surface. You now want to ink parts of this sketch, but the ink bleeds a little into the texture of the gesso?
You can use a clear varnish such as MM6 Polymer matt varnish over the top before inking; however, depending on how heavily you have applied your pencil, you will find that the graphite will repel the varnish over any heavily applied areas of pencil. Also, there would be a good chance that the graphite may be moved over the page by the brush/varnish as well.
This is because the graphite from the pencil does not penetrate the surface and form a bond, like paint does which means it simply sits on the top of the gesso without any adhesion. Excessive amounts of pencil will be able to be moved on the paper if you brush any sort of sealer over it.
Using thinned down Matisse Flow Formula paints may work better than the inks as they have more binder and body - just thin them to a slightly thicker consistency than ink and use a fine brush.Further information can be found at www.derivan.com.au
