Two primary types of ink are used for the printing of textiles. Printing ink and plastisol inks dependent on water. Each ink is discussed in detail as follows: water based ink uses dyes or pigments as solvent in a suspension with water. Water evaporation is needed to set or cure the ink. This treatment can take place either at room temperature or with a forced-air dryer according to the particular water-based ink used and the production speed or volume.

What is Plastisol?

Plastisol ink is a pvc-based device with no solvent at all. It is a 100% solid ink device. Plastisol is a thermoplastic ink because it is important to dry the printed ink film at a high enough temperature to activate the pvc resin molecules known as gelling and plasticizer that link and therefore reinforce or cure. Temperature at which most "plastisol" inks are available for textile printing at 160 ° c to 200 ° c.

How Plastisol works?

Plastisol is the choice ink for printing finished items like t-shirts, sweatshirts, jackets and tote bags. For printing yard goods, water-based tin is the option; either in piece form or on a roll. The technological advantages and drawbacks of both inks are for use in particular applications.

Plastisol ink often produces an ink film that you can feel with your hand on the surface of the fabric. The will the opacity, the thicker the film would be.

Plastisol inks can be left without interruption of the mesh in the screen for longer periods of time. It is ready to use more than 90 percent of the time out of the bag. Wet-on wet can be printed in most applications, allowing increasing production rates. It is available in formulations printable on light and dark fabrics.

Critical activities of plastisol tint

One of plastisol tint's most critical activities is to keep the tint clean. What this means is that it is highly helpful and cost-effective to prevent contaminating plastic isol colors with soil or even other inks. By ensuring clean shop activities, the loss of ink would be significantly reduced. The initial ink container can be returned for reuse with clean ink.

The consistency of plastisol does not degrade unless it is combined with other colors or polluted with foreign materials. Plastisol contaminated with other colors, for mixing with other waste inks, can still be maintained in a separate bottle. Sometimes this waste ink can be used to make new colors or be freshly pigmented to produce a dark color, such as black, which can be used for less important tasks.

If the plastisol is to be disposed of in an uncured condition, hazardous chemical laws refer to the handling of cured or uncured. In the screen and equipment cleaning measures, the greatest environmental threat in the use of plastisol. To emulsify the ink from windows, squeegees and other work surfaces for quick removal, a certain kind of solvent must be used. Waste ink and solvent must be properly disposed of to mitigate the effect on the environment.
