Perfect for your Sublimation Needs
Color: BCMY
If you're into sublimation printing—whether as a hobby or a small business—the Hiipoo Sublimation Ink Refill Bottles are a must-have. This ink performs exceptionally well with a variety of Epson inkjet printers (like the WF-7710, ET-2760, ET-2720, ET-15000, C88, C88+, etc.) and delivers consistently vibrant, professional-looking results across different substrates. The color vibrancy is outstanding. Blacks are deep and rich, and the cyan, magenta, and yellow are true-to-shade. The ink produces clean, detailed images on all kinds of sublimation blanks—from mugs and T-shirts to mousepads and phone cases. Whether you’re pressing on polyester fabrics or coated surfaces, the prints come out sharp and vivid. The bottles are designed for easy refilling, especially with EcoTank models—they fit well and fill smoothly with little to no mess. For other compatible Epson models like the WF series, the process takes a bit more care, but it’s still user-friendly.
This ink has worked flawlessly with heat press transfers on a variety of materials. Once heat-pressed, the colors stay strong—no bleeding, fading, or smudging.The sublimation transfers hold up very well over time. After several washes (for shirts and fabric items), the prints remain intact and bright. It’s also a plus that the ink doesn’t clog the print heads if used regularly and maintained properly. Hiipoo Sublimation Ink is a top-tier choice for both beginners and experienced crafters. It’s affordable, reliable, and produces beautiful results across a wide range of sublimation projects. Whether you’re customizing T-shirts, mugs, or phone cases, this ink brings your designs to life.
Rating: 5/5 – Excellent performance, vibrant colors, and professional results. Highly recommended.

Good ink
Color: BCMY
I like this ink, it has never failed me. You do have to be careful when using it or it will make a mess. It is hard to remember which needle was used for the color, the second time they are used. Washing them out still leave a small amount of color but not so much that it will change the color.

Excelente tinta para sublimación. Los colores salen vivos y muy bonitos en las impresiones. Las botellas son fáciles de rellenar y compatibles con mi Epson EcoTank. Hasta ahora la calidad me ha gustado mucho y las impresiones quedan nítidas y profesionales. Muy recomendada para comenzar en sublimación
