You spend a lot of time creating a detailed design or a complex logo, but after the transfer, the edges look blurry, small details disappear, and the image is not as sharp as expected.
This can make the finished product look less professional, especially when printing customer orders or detailed brand graphics with a DTF printer.
Blurry DTF prints are usually caused by:
- Low-resolution image files
- Incorrect print settings
- Misalignment between the PET film and fabric during heat pressing
How to Fix Blurry DTF Prints
Use a High-Resolution Image
Use an image file with a resolution of at least 300 DPI.
Avoid enlarging low-resolution images before printing. Making a small image bigger does not add detail and often creates blurry edges, pixelation, and unclear text.
Before printing, zoom in on the artwork and check that:
- Fine lines are clear
- Small text is readable
- Logo edges are smooth
- The image is not pixelated
Adjust the Print Settings
Check the printing speed and ink output in your RIP software.
A slower printing speed, such as 30–50 mm/s, may help improve sharpness and give the printer more time to place the ink accurately.
You should also turn off any ink-saving mode when printing detailed artwork. Ink-saving settings may reduce coverage and make fine details look weak or uneven.
Run a small test print before starting a full production batch.
Keep the Film and Fabric Properly Aligned
Before heat pressing, make sure the PET film is positioned correctly on the garment.
Use heat-resistant tape, alignment guides, or positioning tools to hold the transfer in place. This prevents the film from shifting when the heat press closes.
Even a small movement during pressing can create:
- Blurry edges
- Double outlines
- Misaligned details
- Distorted logos
Once the transfer is positioned, keep the garment flat and avoid moving it until the heat-press cycle is complete.
