How can we help you?

To prevent clumping, store your powder in an airtight container within a climate-controlled environment, ideally keeping relative humidity below 50%. Using silica gel desiccants inside your storage containers is highly effective at absorbing lingering moisture.

Iron-on patches typically have high production constraints, including large minimum order quantities (often 50–100+ pieces) and long lead times of several weeks. Additionally, they cannot render fine photographic details or color gradients, making them less suitable for designs that require high visual complexity.

It is generally recommended to perform a quality check if a container has been open for more than 90 days, especially in humid conditions. Before starting a large production run, always perform a press test on scrap fabric to ensure the adhesive still provides consistent coverage and bond strength.

Professional calibration focuses on precision over volume. First, build a custom ICC profile for your specific film and fabric to ensure color accuracy. Second, use the ink limit settings in your RIP software to cap total coverage between 160–220%, and finally, verify that your white ink underbase is appropriately set to 85–90% rather than oversaturating.
