How To Prepare & Apply Supacolor Blocker Transfers

As simple as they may seem, polyester fabrics can actually be delicate to customize at times. This is most evident when applying a heat transfer onto sublimated or patterned polyester, which more often than not results in dye migration on the transfer itself.

If you’re looking to add more to such polyester items, Supacolor Blocker transfers bring the familiar high quality and smooth results of their Wearable transfers to a sublimation and pattern-friendly print. We’ll be showing you how Supacolor Blocker transfers are prepared and applied onto a patterned polyester shirt.

As with Supacolor Wearable transfers, transfer prep is as simple as choosing your size, indicating apparel specs, then sending your vector graphic art to HPN, either in the AI, EPS, or PDF format. You can also send high-quality image files in the PNG or JPEG format that’s at least 300 DPI.

We particularly recommend transparent PNG files if your image requires no background. With your art sent to HPN, it’s then sent to Supacolor to be printed accordingly, which is returned to you once completed. With your Blocker transfer ready, all it takes is applying it onto your sublimated or patterned item.

Turn on your heat press and set it to 8 to 10 seconds, at 290 degrees Fahrenheit with medium-firm pressure.

Once your machine reaches temperature, add your item to the lower platen, then you may optionally pre-press it for 2 seconds to clear out wrinkles and moisture. Pre-pressing won’t be required for items that are 100-percent polyester. After this, add your Blocker transfer where desired, cover your items with a protective sheet and press.

When the machine is done, open it and peel the Blocker transfer hot from a corner with smooth, consistent motion.

Then cover your items again to press for another 2 seconds.

After the second press, your Supacolor Blocker transfer has now been cleanly applied to your polyester fabric. You can learn about Supacolor Blocker transfers and more on our YouTube channel, or at HeatPressNation.com.
