1. Ink Smudging or Bleeding

Problem:

Ink spreads beyond the intended design, causing blurry or messy prints.

Solution:

● Ensure you’re using the correct film and ink combination.

● Reduce ink saturation in your RIP software settings.

● Allow prints to dry properly before applying adhesive powder.

2. Poor Adhesion of Powder to Ink

Problem:

The adhesive powder does not stick properly to the ink, leading to weak transfers.

Solution:

● Check that the ink is wet enough before applying the powder.

● Store adhesive powder in a dry place to avoid clumping.

● Use a curing oven or heat press at the right temperature to melt the powder evenly.

3. Film Jamming in Printer

Problem:

The DTF film gets stuck in the printer, disrupting the printing process.

Solution:

● Ensure the film is properly aligned and loaded.

● Regularly clean the printer rollers to prevent dust buildup.

● Use high-quality DTF film that matches your printer specifications.

4. Dull or Faded Colors

Problem:

Printed colors appear washed out or lack vibrancy.

Solution:

● Use high-quality DTF inks for better pigment retention.

● Adjust color profiles and saturation levels in your RIP software.

● Perform regular printhead cleaning to prevent ink clogs.

5. Prints Peeling Off After Washing

Problem:

Designs start peeling after a few washes, reducing durability.

Solution:

● Ensure proper curing time and temperature.

● Use high-quality adhesive powder for strong bonding.

● Advise customers to wash garments inside out with mild detergent.

6. Ink Clogging the Printhead

Problem:

The printhead gets clogged, leading to streaks or missing colors.

Solution:

● Perform regular printhead cleaning cycles.

● Use genuine, high-quality DTF inks to prevent residue buildup.

● Keep the printer in a dust-free environment to avoid contamination.

7. Poor White Ink Opacity

Problem:

White ink appears transparent, affecting color vibrancy.

Solution:

● Shake white ink cartridges regularly to prevent pigment settling.

● Increase white ink density in your RIP settings.

● Use a double-pass white ink layer for better opacity.

8. Film Curling or Warping

Problem:

DTF film curls up, making it difficult to feed through the printer.

Solution:

● Store film in a dry, flat place away from heat and humidity.

● Preheat the film slightly before printing to flatten it.

● Use a film holder or guide to keep it steady.

9. Powder Residue on Garments

Problem:

Excess adhesive powder remains on the fabric, causing rough textures.

Solution:

● Shake off excess powder before curing.

● Use a brush or air blower to remove loose powder.

● Adjust curing temperature to ensure complete melting of powder.

10. Misalignment in Multi-Color Designs

Problem:

Layers of different colors don’t align correctly.

Solution:

● Calibrate the printer for accurate registration.

● Use precise design alignment settings in your software.

● Print test samples before mass production.
