Before we answer “Why Plastisol Is Still the Best Screen printing Ink,” let’s first define what Plastisol Ink is. Plastisol Ink is a suspension made of Poly Vinyl Chloride and a liquid plasticizer. When it is heated, it flows smoothly like a liquid. It is used for screen printing purposes and as a textile ink.
Since its inception in the 70s, plastisol ink has revolutionized the screen printing industry. Its ability to produce a permanent glossy finish has made it the industry standard. Plastisol ink has been voted the best screen printing ink on the market.
It is made of PVC resin and plasticizers. Once the temperature reaches 325°F, the plasticizers react with resin to form a permanent glossy print that won’t wash off.
Plastisol is still the best screen printing ink
These are the top five reasons why Plastisol ink is the best for screen printing and the most desired by screen printers.
01. It creates vibrant prints:
Plastisol ink produces vivid, vibrant prints that no other ink can. It prints vividly, even on darker substrates. It layers on top of the substrate rather than absorb it into the fabric like other water-based or discharge inks. This allows you to create solid prints on any substrate.
02. Plastisol ink won’t dry out
Plastisol is not as fast drying as water-based inks. This is a benefit that screen printers who use water-based paints will appreciate. Plastisol must reach extreme temperatures to cure. It doesn’t stick to the screens, even during long press runs. It makes printing jobs easier. Print shops can also reuse the screens quickly, so you don’t have to clean them out between jobs. You can re-use the excess ink by putting it back into the bucket.
03. All Additives Acceptable
Many additives can be used with plastisol, making it possible to create any design you like on your t-shirt. Reducers can be used to thin the ink to make it easier to print. Soft-hand additives can be used to give your ink a lighter feel. To create special effects on your tee-shirt prints, you can use puff, suede, or glitter.
04. Printing made easy:
Plastisol is an easy-to-use choice for screen printers due to its many uses. You can print plastisol wet-on-wet. The printers place it under the base and flash cure it. They then print over quickly. They can also blast the pinholes quicker with a spotgun.
05. It’s easy to dispose of:
Plastisol ink does not require special attention to be disposed of. Plastisol ink that has been cured is not considered to be hazardous. You can cure any excess plastisol ink and get rid of it.
It produces bright, durable prints that are easy to use. Experts believe it will continue to be used in screen printing for many years due to its many advantages.
When they have a variety of printing jobs to do, printers will turn to plastisol. We believe that plastisol will continue to grow in popularity. We would love to hear your opinions on plastisol.
What temperature does plastisol cure at? Plastisol doesn’t cure at room temperature. Plastisol ink would need to be cured at temperatures between 145°C and 165°C or 300o F-330o F.
What’s the difference between plastisol inks and water-based ones? Plastisol can print apparel with a plastic-based dye, while we can use water-based ink for apparel printing and retail printing. The main difference between the two is that water-based ink will dye the fabric. It will completely replace the fabric’s color with its own. On the other hand, the plastisol ink creates a layer over the fabric that covers the particular area.
Is plastisol ink safe? Plastisol ink may be toxic or non-toxic depending on where it is made. However, most premium plastisol manufacturers make non-toxic, PVC- and phthalates-free ink.
Is it possible to print plastisol onto polyester? Yes, polyester and plastisol can be used together. This is why you can print on polyester with plastisol.
How can plastisol ink be harmful to your health? Plastisol inks can be made from polyvinylchloride, which reacts with other chemicals and forms dioxins. Dioxins, which are extremely toxic chemical compounds, can be dangerous to your health. Plastisol inks can be used safely if they are handled with care.
