Are you one of those DTF shops that orders “just enough” ink, film, and powder to get through the week?
While it may seem cost-efficient, this approach can lead to damaged consumables, expensive repairs, and production delays—especially during seasonal temperature extremes.
I’ve managed operations for one of the largest DTG print-on-demand companies in the U.S., overseeing 36 Kornit Avk printers across three locations. The biggest lesson I learned? Proper supply planning saves money, protects equipment, and keeps production running smoothly.
The Cold Truth About DTF Ink Storage
No water/glycol-based DTF ink is truly freeze/thaw stable. Even when manufacturers claim it is, none of my industry partners have ever guaranteed it.
When ink freezes, its physical composition changes—sometimes permanently—causing:
- Printhead clogs
- Inconsistent ink flow
- Loss of color quality
Tech Guru Tip: In colder months, order enough DTF ink for at least 90–120 days before temperatures drop. This prevents shipping or storage in dangerous cold conditions.
Heat Damage and DTF Film Performance
High temperatures are just as dangerous for DTF transfer film. In testing, film exposed to over 90°F (32°C) for more than 3 hours showed:
- Tracking and feeding issues in the printer
- Poor powder adhesion
- Weak or uneven transfer quality
If your shop operates in hot climates, order film before peak summer heat to maintain consistent print quality.
Best Practices for Ordering and Storing DTF Supplies
Follow these steps to protect your DTF consumables year-round:
- Avoid extreme temperature exposure – Never store supplies below 45°F (7°C) or above 85°F (29°C) and avoid if you can shipping in the extreme temperature as well.
- Plan quarterly, not weekly – Large POD (Print-on-demand) shops should forecast supply needs for 3–4 months.
- Log supply quality issues – If print quality suddenly drops, check if recent shipments were temperature-compromised.
- Choose reliable suppliers – Work with vendors who refuse to ship during unsafe weather conditions.
The Real Cost of Poor Supply Planning
Temperature-damaged ink and film usually fail during peak production seasons, creating:
- Missed order deadlines
- Emergency re-order costs
- Reduced customer trust
Being proactive with your supply strategy is far cheaper than replacing printheads or reprinting damaged orders.
Final Word: Protect Your Shop Year-Round
Whether you run a small custom DTF shop or a large POD facility, don’t gamble with your consumables.
Order in bulk before temperature extremes, store products in climate-controlled conditions, and partner with suppliers who understand the importance of protecting your business.
Your printheads, customers, and bottom line will thank you.
