High temperatures in summer pose a real challenge for the storage and use of DTF (Direct-to-Film) inks. The core principles are temperature control, moisture protection, and light avoidance, with special attention given to white ink.
📦 Storage: Giving Your Ink a Stable "Home"
Control Environmental Temperature & Humidity
Unopened ink should ideally be stored at a temperature between 5°C and 30°C, with humidity levels between 40% and 80%. When indoor temperatures rise too high in summer, it is recommended to use air conditioning to cool the environment, and keep the storage area cool, dry, and well-ventilated.
Strictly Avoid Light Exposure
Direct sunlight can raise the temperature of the ink, affecting its performance and shelf life. The safest practice is to store ink in light-proof cabinets or in their original cardboard boxes.
White Ink Needs Extra Care
White ink contains titanium dioxide as its main component, which makes it more prone to sedimentation than color inks. If left unused for long periods, it can affect print quality. It is recommended to invert unopened ink cartridges once every two weeks to help slow down pigment settling.
🖨️ Usage: Keeping Ink in Optimal Condition
Workspace Environment Matters Too
The optimal operating environment for your printer is a temperature between 15°C and 30°C, with humidity maintained between 35% and 65%. Low humidity can cause static electricity issues, while high humidity may negatively impact print quality.
Shake White Ink Thoroughly Before Use – This is the most critical step! After prolonged storage, white ink must be shaken thoroughly and evenly before use. For best results, use a professional ink shaker to ensure the pigment is evenly distributed.
Pay Attention to "Post-Opening Shelf Life"
Always seal the bottle cap tightly after each use, and try to use the ink within 15 days of opening to prevent contamination and performance degradation.
✨ A Note for Bbtransfer M1630 Pro Users
