Plastisol. A plastisol is a colloidal dispersion of small polymer particles, usually polyvinyl chloride (PVC), in a liquid plasticizer.When heated to around 180 °C (356 °F), the plastic particles absorb the plasticizer, causing them to swell and fuse together forming a viscous gel.
Screen printing is a printing technique where a mesh is used to transfer ink (or dye) onto a substrate, except in areas made impermeable to the ink by a blocking stencil.A blade or squeegee is moved across the screen in a "flood stroke" to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact.
The invention of plastisol in 1959 provided a more durable and stretchable ink than water-based inks, allowing much greater variety in T-shirt designs. Very few companies continue to use water-based inks on their shirts; the majority prefer plastisol because it allows printing on varying colors without the need for color adjustment at the art ...
Plastisol or water-based inks are applied to the shirt through mesh screens which limits the areas where ink is deposited. Threadless printing techniques include gradients and simulated process, UV color change, oversized printing, puff, belt printing, vinyl, super glow, flock, embroidery, suede, metallic, blister, foil, and high density.
PVC was synthesized in 1872 by German chemist Eugen Baumann after extended investigation and experimentation. [12] The polymer appeared as a white solid inside a flask of vinyl chloride that had been left on a shelf sheltered from sunlight for four weeks.
