Hey there! I'm a supplier of 80gsm Sticky Sublimation Paper, and I know how important it is to have water-resistant prints on this paper. Whether you're using it for arts and crafts, commercial printing, or any other application, water resistance can make a huge difference in the longevity and quality of your prints. So, let's dive into how you can achieve that.
Understanding the Basics of Sublimation Printing
Before we get into the water-resistant part, let's quickly go over how sublimation printing works. Sublimation printing uses heat to transfer dye from the sublimation paper onto a substrate, like fabric or ceramic. When the heat is applied, the dye turns from a solid to a gas, skipping the liquid phase, and then bonds with the substrate. This process creates a vibrant and long-lasting print.
But here's the thing — the standard sublimation print on 80gsm Sticky Sublimation Paper isn't always super water-resistant. That's because the dye bonds with the substrate, but it can still be affected by water if not properly protected. So, what can we do to make it more water-resistant?
Choosing the Right Inks
The type of ink you use plays a huge role in the water resistance of your prints. There are two main types of sublimation inks: water-based and solvent-based.
Water-based inks are more environmentally friendly and produce bright, vivid colors. However, they're not as water-resistant as solvent-based inks. Solvent-based inks, on the other hand, are more durable and water-resistant. They penetrate the substrate better and form a stronger bond, making the print less likely to fade or run when exposed to water.
When choosing an ink, look for ones that are specifically designed for water resistance. Some manufacturers even offer inks with added UV protection, which can also help prevent fading over time.
Heat Press Settings
The heat press is where the magic happens in sublimation printing. Getting the right settings is crucial for a water-resistant print.
First, make sure your heat press is calibrated correctly. An inaccurate temperature or pressure can result in a poor-quality print that's not as water-resistant. The ideal temperature for sublimation printing on 80gsm Sticky Sublimation Paper is usually between 380°F and 400°F (193°C and 204°C), but it can vary depending on the ink and substrate you're using.
The pressure is also important. Too little pressure, and the dye won't bond properly with the substrate. Too much pressure, and you could damage the paper or the substrate. Aim for a medium to firm pressure, and make sure the heat press is evenly distributing the pressure across the entire print area.
The time you leave the print in the heat press is another factor. Most sublimation prints require between 45 seconds and 2 minutes of pressing time. Again, this can vary, so it's a good idea to test different settings on scrap material before doing a full print.
Post-Printing Treatments
Once you've printed your design, there are a few post-printing treatments you can do to make it more water-resistant.
Laminating
Laminating is one of the most effective ways to protect your print. There are two main types of laminates: hot and cold. Hot laminates are applied using a heat press, while cold laminates are applied using pressure.
Hot laminates tend to provide better adhesion and water resistance, but they can also be more expensive and require special equipment. Cold laminates are more affordable and easier to apply, but they may not be as durable.
When choosing a laminate, look for ones that are specifically designed for sublimation prints. They'll have the right properties to bond with the dye and provide a protective layer.
Coating
Another option is to apply a water-resistant coating to your print. There are several types of coatings available, including spray-on coatings and brush-on coatings.
Spray-on coatings are easy to apply and dry quickly. They're also great for covering large areas. Brush-on coatings, on the other hand, allow for more precise application and can be used on smaller or more detailed prints.
When applying a coating, make sure to follow the manufacturer's instructions carefully. Apply the coating evenly and allow it to dry completely before handling the print.
Substrate Selection
The substrate you choose can also affect the water resistance of your print. Some substrates are more absorbent than others, which can make the print more prone to water damage.
For example, natural fabrics like cotton are more absorbent than synthetic fabrics like polyester. If you're printing on cotton, you may need to take extra steps to make the print water-resistant, such as using a more water-resistant ink or applying a coating.
On the other hand, synthetic fabrics like polyester are less absorbent and tend to bond better with sublimation dyes. They also have better water resistance on their own, so your print is more likely to stay looking good even when exposed to water.
Testing Your Prints
Before you start using your prints in a real-world application, it's a good idea to test their water resistance. You can do this by spraying the print with water or soaking it in a shallow dish of water for a few minutes.
After the test, check the print for any signs of fading, running, or damage. If the print holds up well, you're good to go. If not, you may need to adjust your printing process or try a different treatment.
Other Considerations
There are a few other things to keep in mind when trying to make your prints on 80gsm Sticky Sublimation Paper more water-resistant.
Storage
How you store your prints can also affect their water resistance. Make sure to store them in a dry, cool place away from direct sunlight. Exposure to heat, humidity, and sunlight can all cause the print to fade or lose its water resistance over time.
Handling
Be careful when handling your prints, especially when they're wet. Rubbing or scratching the print can damage the dye and reduce its water resistance. Use a soft, dry cloth to clean the print if necessary.
Conclusion
Making the print on 80gsm Sticky Sublimation Paper more water-resistant takes a combination of the right inks, heat press settings, post-printing treatments, and substrate selection. By following these tips, you can create prints that are vibrant, long-lasting, and able to withstand exposure to water.
