Removing a varnish coating from an intaglio or planographic print is a potentially hazardous procedure. Difficulties are compounded if the ink contains additives and adulterants or the print has been hand-coloured with solvent sensitive media. In the case of seriously discoloured and damaged artefacts the risks involved in removing any varnish may be justified. Traditionally the paper conservator's choice of options has been rather limited which heightens the potential risks. Solvent poultices and gels may offer certain advantages over more traditional approaches and, although fears as to the long-term implications of residues have yet to be fully researched, current experiements look encouraging.
