The ink and is porous enough to permit good ink penetration.

Plastisol inks do not color the fibers like a dye.

Instead the ink wraps around the fibers and makes a mechanical bond with the fabric.

For this reason, they will not adhere to non-porous substrates such as plastic, metal, and glass.

Store plastisol inks at room temperature. Prolonged exposure to temperatures above 90º F (32º C) can cause the ink to start to cure while it’s still in the container.

Curing plastisol inks is a matter of exposing them to the proper amount of heat for the correct length of time.

Correct curing of plastisol ink is extremely important.

The most common problem encountered with plastisol inks is poor washability.

In almost every case, this is due to incomplete ink cure.

When plastisol is heated, the resin particles absorb the surrounding liquid plasticizer .

swell, merge with each other and form a tough, elastic film.

It is generally impossible to overcure direct prints because the overcure temperature is above the scorching point of the garment.

However, it is not recommended that you heat the ink layer above 350º F (176º C).

Above this temperature puff inks fall like a cake .

When you slam the oven door, and problems with dye migration are greatly increased.

If the entire thickness of the ink is not brought to the correct curing temperature the ink will be under-cured .

The resin has not absorbed all of the plasticizer and the ink will crack and flake off the garment when washed.

Finally sunlight stencils will reach out to you.
