Printers inks are actually powders that bond to appear solid. Use the liquid that forms on top of enamel metallics to rejuvenate. The acrylic inks so popular from the manufacturers are NOT printers inks. Thin with the manufacturer thinners.

Just to check Rod, yours are the type that thin with turps/spirits and smell a little like oil paint?

If they smell like oilpaint put a small amount of white spirit above it.
That trick I have from Stuart from Stormtroopers who sell the stuff to me.
It works great. I have them now for almost tree years.

Thats right marc.
It depends where you got them to be honest.
Mine were thinned with white spirit.
Due to the new postal legislation i am now looking at thinning them with another dilutant that can be sent by air mail.
If there mine they shud be ok if not ask the manufacturer

Thank you guys, once again for the help..

Yes I think I know what you mean, had the same thing back when I first got some printing ink from a friend to test out.
As I didn't know back then the thing to do is try to protect the ink from 'drying' in the first place. The drying process is really oxidation of the oil so it's air you want to prevent getting to it (even the air left in a small container when the lid goes back on has enough oxygen in it to be a problem*). If the ink isn't too liquid crazy as it sounds you could try covering it with water, that's not an ideal long-term solution but it can work well. A better fix might be to drape a bit of plastic** over the remaining ink, pressing it directly into the surface.
*They use spraycans of inert gas to spray into open cans to prevent this in a commercial setting.
**Food wrap might be enough, but some won't work for this.

The gum you are referring to Stuart is 'Gum Arabic' which, nowadays, has been replaced with a wholly synthetic resin in trade printing inks.
Anti-oxident sprays used to prevent skinning in modern inks are very similar to WD40 which, in itself, is actually a water repellent.
If you want to prevent trade inks skinning, you take a piece of strong paper similar to baking paper, and rub oil into and over it. It can be any oil of a machine type, not cooking oil, when the paper is saturated wipe off the excess on a piece of kitchen towel and lay this directly onto the surface of the ink. Once done, you should ideally put a lid on the container to prevent the oil drying out. This will in no way effect the ink, and will prevent skinning for years, as you can use the paper over and over after each time you have used the ink.
