Direct-to-film printing is an innovative method of printing apparel with vibrant prints, custom transfers of logos, quotes, or favorite landmarks. Many people now diverted their attention from old methods of screen or letterpress printing to DTF printing because this is more versatile. However, like any other printing process, DTF printing also has its own challenges. If you are also one of those tired of certain issues, this guide can help!
Common DTF Printing Issues & Their Solutions
DTF printing is basically a process of printing on fabric and the process involves the direct transfer of a design from a PET film to a fabric via heat press. The specialized companies like dtfvirginia.com can help you get your designs in now time.
Here are some issues that hinder the printing process and prevent damage to the fabric. Let’s find your issue and get a solution. Here you go!
Ink Smudging or Bleeding
Ink usually smudges usually during or after the transfer process or when the fabric does not handle it or spreads around the intended area. It usually happens due to excessive ink application, low-quality film, incompatible ink, or incorrect curing temperature. No worries we have got the solution right here!
- You can reduce the ink saturation in your design software to avoid oversaturation.
- By using high-quality PET film, you can avoid this issue.
- If you keep the curing temperature between 150-170°C or 300-340°F, this will not happen because over-curing can cause smudging.
Poor Adhesion of Transfers
If your printed design does not stick properly to the fabric or peels off after washing, it is due to improper heat press settings, whether it is temperature, pressure, or time. Sometimes, the print does not stick due to poor-quality adhesive powder or incorrect fabric type. For this, you need to:
- Correct the settings; the temperature should be 160-180°C, and pressure should be applied even for 10-15 seconds.
- You can use TPU DTF powder, which has been specifically created for better adherence.
- Choose a compatible fabric like this DTF, which works best on cotton, polyester, and blends. Test on new fabric types before full production.
Faded or Dull Colors
After printing if you find out the prints appear washed out or lack vibrancy compared to the original design. Then it might be due to low-quality ink or film, incorrect color settings in the design software, or the print must be under-cured. You might opt for dye sublimation transfers which is also an efficient printing method.
- Use premium sublimation or solvent-based inks that deliver better color accuracy and longevity.
- Make sure you are using the correct ICC color profiles for DTF printing.
- Follow proper curing time and temperature to lock in vibrant colors.
Ink Clogging in the Printer
Is your ink clogged in the nozzle, and are you getting frequent uneven prints or white streaks? It is probably due to infrequent printer maintenance, the use of low-quality or incompatible inks that dry out in the nozzle, or maybe you are using your printer after so long.
- You need to clean the printhead regularly and perform nozzle checks.
- Stick to manufacturer-recommended inks to prevent clogging.
- Print a small test image whenever you use the printer after a long time to keep the ink flowing.
White Ink Issues
White ink does not print or appears patchy, and it impacts the color balance and opacity. The reason is ink settling in cartridges, printhead misalignment, or low ink levels. To solve this issue:
- You need to shake white ink cartridges daily to keep the pigment mixed.
- Test the alignment to ensure accurate printing.
- Keep a close eye on white ink levels to prevent interruptions during printing.
Ghosting or Double Imaging
After getting the DTF print does your fabric have another faint duplicate image beside the main design and ruin the print quality? The issue is with the movement during heat pressing or incorrect film alignment.
- Simply use heat-resistant tape to hold the film in place during pressing.
- Ensure the fabric and film do not shift when closing or opening the heat press.
Final Thoughts
DTF printing offers incredible results, but a few little mistakes can ruin the complete design. However, it is important to learn from the mistakes and overcome these common challenges to produce high-quality, durable designs. Learn to keep your printer in good condition and follow proper printing and curing processes. I hope these solutions help you!
