The best tip for all ink systems is, in a word, ‘lids’. All ink is supplied with a lid and the lid should always be used.
In water-based ink systems, the lid is essential to prevent the moisture in the ink from evaporating. With plastisol inks, the lid is just as important to avoid contamination from all the airborne contaminants that are found in an average print shop. These can, and invariably do include: tired wasps, glitter from that job you did two years ago, and the missing screw from the back of the radio remote, not to mention the fluff and bits of cotton found inside 3,000 blue shirts! This creates a carpet on the top of the ink, blocks the screen and can alter the colour and consistency of the end product. Replace the lid!
