If you're not doing wet plate, what are you coating? What type of plate? Are you talking about the varnish coat or the emulsion coat? What do you mean by "printed"... Are these negatives? Need more information. Collodion will dry very fast, so if that's what you're talking about, something is wrong. Maybe you've used flexible collodion? Varnish should not be tacky after 2 days either.
