Why does it take 12 days to produce heat transfer film?

Below is a detailed breakdown of the process, focusing on cylinder making, printing, drying, gluing, quality control, die-cutting, packaging, and shipping:

3

1. Cylinder Making (Engraving) – 1–2 Days
Gravure Cylinder Engraving: The printing pattern is
laser-engraved onto metal cylinders (for gravure
printing).
Precision Required: High-resolution designs need meticulous engraving to ensure color accuracy.
Testing & Adjustment: Cylinders must be checked for defects before printing.

2. Printing – 2–3 Days
Multi-Layer Printing: Each color is applied separately using engraved cylinders.
Registration Alignment: Colors must align perfectly to avoid misprints.
Slow Drying Inks: Some specialty inks (metallic, fluorescent) take longer to set.

3. Drying the Ink – 1–2 Days
Controlled Drying: Prints pass through drying tunnels (infrared/UV curing).
Preventing Smudges: Insufficient drying leads to sticking or color bleeding.
Humidity & Temp Control: Rushing drying can cause warping or poor adhesion.

4. Glue (Adhesive) Coating – 1–2 Days
Hot-Melt or PU Glue Application: A uniform adhesive layer is coated.
Drying/Curing: The glue must fully dry to ensure proper transfer later.
Thickness Control: Uneven glue affects bonding strength.

5. Quality Inspection – 1 Day
Adhesion Testing: Checks if the film bonds correctly to fabrics/substrates.

Color & Print Defects: Manual/automated inspection for flaws.

Heat Resistance Test: Ensures durability during hot pressing.

6. Die-Cutting (if needed) – 1 Day
Precision Cutting: Shapes/kiss-cuts are made for easy application.

Waste Stripping: Excess material is removed.

Final Check: Ensures cuts align with design specs.

7. Packaging & Shipping – 1 Day
Rolling/Slitting: Film is wound into rolls or cut into sheets.

Labeling & Boxing: Prepared for bulk or custom orders.

Logistics Coordination: Shipping time depends on destination.
