How to Do Perfect Sublimation Printing? & How to Avoid Humidity in Printing?

Hello, good afternoon, my dear friends. Today is nice day in Nanjing, now I want to talk about how to do perfect sublimation printing. During sublimation transfer printing, we should care for many problems, then we can get a beatiful patten. Please read my this article, I will share you some tip during printing process.

In addition to being mindful of moisture in pressing, you should also focus on your work environment. High humidity levels usually contribute to moisture issues. A dehumidifier can help control these issues, but reducing it too much can have negative effects on the inks and your equipment.

It’s wise to invest in a hygrometer and take some readings. The ideal operating conditions for sublimation are 59°F – 77°F or 15°C to 25°C with above 35% relative humidity (no condensation).

• Keeping Your Heat Press Clean

It is important to protect the rubber pad that is attached to the lower section of the heat press. The same is true for the rubber pad found in a mug press. Covering the pad with a protective sheet of paper, a paper towel or a Teflon sheet will prevent sublimation ink from being absorbed into it.

If You Use Paper: Choose an inexpensive white bond paper or a roll of white paper (cut as needed), and discard after each pressing. Unprinted newsprint paper is also a good choice.

If You Use a Paper Towel: Choose an inexpensive, white, non-textured brand (the texture will leave a pattern on the substrate), and discard after each pressing
If You Use a Brown Teflon Sheet: Clean it with alcohol after each pressing

• Preventing Ghosting

Sublimation requires a tight connection between the transfer page and the blank product when under heat. For the best results, as the inks gas and dye the product, you must ensure that the sublimation paper doesn’t shift. If the transfer page moves during the sublimation process, this could result in a blurry image or ghosting, which resembles a shadow effect.
To prevent this, always fix the transfer paper to the product itself using heat-resistant tape or repositionable (temporary) spray adhesives.

• Hard Substrates

When decorating hard substrates, use heat-resistant tape to attach the transfer page to the product. Do not tape across the image area, as this can often damage the image quality. Press the product normally, and then remove the transfer carefully. Heat tape can be purchased from your distributor.

• Soft Substrates

One of the most common difficulties in working with soft substrates is having dust, lint and other fibers from the air imprint into the fabric when pressing. This will leave little blue marks on the fabric, which can detract from the quality of your print.
The best way to reduce this to use a sticky lint roller before each press. A simple tape-based roller that you buy at the local grocery store will lift most of the particles that you can see, and many others that are invisible to the naked eye. It’s a good idea to get into the habit of lint rolling fabrics before placing the transfer paper.
To use spray adhesive, spray a light mist on the image side of the transfer paper from about 12”/30cm away. Do not spray the product. Then, simply press the transfer paper to the product. If you position it incorrectly, you can lift it off and reposition it.It is difficult to tape to soft substrates, like t-shirts and mousepads. Instead, you can use a repositionable adhesive spray to tack the transfer paper to the product.

Press the product normally and remove the transfer. Ask your dealer about suitable adhesive sprays.
