1L Custom Ink Dtg Printheads I3200 F2000 F2080 White Base Ink

This white DTG ink is our core product specifically developed to address the challenges of printing on dark garments. It features a high-concentration pigment formula that provides excellent opacity, forming a pure and durable white base on black or dark cotton fabrics. This creates a solid foundation for vibrant color prints. The ink is designed for smoothness and stability, making it compatible with popular DTG printers like Epson, reducing the risk of clogging during production and ensuring reliable continuous printing. After proper curing, this white base will tightly bond with the fabric, ensuring the overall design is wash and wear-resistant.

This white DTG ink is primarily designed as base ink for printing on dark garments. Its ideal printing medium is pure cotton fabrics, such as black, navy, or dark gray cotton T-shirts and sweatshirts, where it creates a clean, high-opacity white base.

It can also be used on cotton-polyester blend dark fabrics. However, it’s important to note that if the fabric contains a high percentage of synthetic fibers (like polyester), it may affect the adhesion and final whiteness of the white ink. Therefore, for high-demand orders, it is recommended to prioritize dark fabrics with a higher cotton content.

The most crucial point is: This white ink is mainly used as a base layer. Before printing color designs on dark garments, you must first print and cure this white base layer. Its purpose is to allow the subsequent color inks to appear vibrant and clear on dark fabrics, solving a key challenge in DTG printing. Before use, be sure to shake the ink thoroughly to ensure even opacity.

Frequently Asked Questions about DTG White Ink

• Q: Why do you emphasize that this white ink is mainly used as a "base layer"? Can I print white designs directly with it?
  A: Of course, you can print pure white designs directly. However, its core design is intended as a base layer: first print it on dark garments to create a white base, and then layer color designs on top. This ensures that vibrant colors like red and yellow appear bright and clear on black T-shirts. When used alone, it can also print full, solid white designs.
• Q: What does "high opacity" mean for the white ink? Will it show through when printed on black clothing?
  A: "High opacity" refers to the ink's ability to cover the underlying fabric color (such as black). Our formula is designed to create an opaque white layer with a single print pass, effectively blocking the dark fabric color from bleeding through and preventing any grayish shadows. To be absolutely certain, for pure black fabric, we still recommend using a double white base pass for key areas.
• Q: After printing the white base layer, do I need to fully cure it before printing color on top?
  A: Yes, this is a critical step. After printing the white base layer, it must be fully cured using heat press or a tunnel dryer to ensure it is completely dry and securely bonded before printing color designs on top. If the white base is not fully dried before printing color, it may cause muddiness, blurry designs, and potentially damage the printhead.
• Q: The white ink becomes very thick and even can't be squeezed out after sitting for a while. Does this mean it's bad?
  A: This is not a sign that the ink is bad. The high pigment density in the white ink causes it to naturally settle and thicken over time, which is a normal physical phenomenon. Before use, make sure to shake the ink bottle vigorously for at least 2-3 minutes, or use a dedicated mixer until it returns to a uniform liquid state. This is essential to ensure smooth printing and proper opacity.
• Q: Can white ink be used in the same printhead as color inks?
  A: Yes, this is the standard operation for most DTG printers. The key is following a proper cleaning process. When switching from long-term white ink printing to color printing, we recommend performing a "Strong Cleaning" and printing a test page to ensure no white pigment residue is left that could affect the purity of the colors. The printer's automatic cleaning function is usually sufficient to maintain smooth switching between inks.
