In the fast-paced world of DTF printing, perfection is the goal of excellence. But an annoying problem has came out: black DTF prints have unwanted shiny spots. As enthusiasts strive for perfection, these irksome spots can mar the final outcome. We’ll break down the issue, identify its causes, and provide you with the resources you need to get rid of those elusive, sparkling flaws in this tutorial. Stop worrying and let’s explore practical ways to make your black DTF prints perfect.

How to Fix Shiny Spots on Black DTF Prints

The Problem Explained

Alright, let me break it down. I’ve been employing the hot peel approach to experiment with DTF transfers. The issue is that these glossy areas scuff the pattern once they are pressed. It’s unusual because they resemble wet patches, but here’s the kicker — they’re dry. You can only notice them under certain lighting conditions, but they’re bothering me big time.

After explaining everything to the firm, they are just as perplexed as I am. They said my instructions were spot on. They added a suggestion, which I’m not quite believing into, that the transfers may have heated up a little during shipment. It’s like attempting to solve a puzzle; I’m trying to determine whether I pressed too hard or not hard enough.

Causes of Shining Spots on Black DTF Prints

Now, let’s get into the specifics of why your black DTF prints are displaying those bothersome glossy spots.

Problems with Ink:

  • Quality Is Important: Poor quality ink might cause uneven drying and glossy patches. Make sure the premium DTF ink you’re using is made for the particular printer you own.
  • Substrate-Related Issues: Surface Tension Issues: When ink settles unevenly, it might leave behind glossy patches due to unequal substrate tension or surface imperfections. Verify that your substrate is smooth, clean, and tensioned correctly.
  • Printing Environment Factors: Fluctuations in temperature and humidity during printing can influence ink curing. To prevent differences that might result in glossy spots, make sure your printing environment is constant.

Insufficient Drying Time/Temperature:

It is possible that the drying procedure was not completed in a timely or warm enough manner. The first step towards a good print is making sure it dries enough.

  • Incomplete Curing: Curing is the key to locking in your design. Problems can arise if it wasn’t given enough time or heat. Verify the curing procedure twice to ensure a complete setting.
  • Garment Permeability and Glycerin Humidity: Some clothing may not be compatible with the humidity of glycerin. The fabric’s permeability could have an influence on how well the DTF procedure works. Evaluate the garment’s characteristics to ensure compatibility.
  • White Ink Glycerin Dilemma: There are certain guidelines for using white ink. Glycerin is meant to prevent printhead clogs from occurring, but it takes time to work. To prevent any snags in the printing process, let it dry before proceeding with the important phases of adding powder and curing.

Humidity vs Undercuring Analysis:

Come along, let’s investigate. The culprits might be a covert humidity problem or undercuring. Place your bets on the latter or perhaps a hiccup in the timing of powdering and heating the film. For a perfect DTF performance, time and humidity must dance together, just as when you discover the appropriate beat.

When these adjustments are made, your DTF prints will be produced in a well-cured and dry environment, with humidity and undercuring being minor bumps on the road. Now, watch those vibrant prints come to life!

Boosting Pressure for Flawless Prints:

It all comes down to exerting a little bit extra pressure at times. Press harder while you’re pressing to boost the level of difficulty. This eliminates any possibility of inconsistent graphic transfer onto your clothing and guarantees a strong transfer.

Double Press for Extra Assurance:

If unsure, try again with a second round. Place a second piece of paper or an extra shirt on top after the first press and press one more. It’s similar to adding that last layer of confidence to your print and smoothing over any possible flaws.

Beware of Teflon Shine:

Teflon sheets could be cunning troublemakers, giving your prints an unwelcome sheen. If you want to preserve the organic look of your design, go with alternatives like paper or an additional shirt. It’s important about maintaining that genuine appearance without adding more shine.

Conclusion | Black DTF Prints issues

To sum up, learning the craft of DTF printing requires careful attention to detail. Vibrant, faultless prints are made possible by streamlining the curing procedures, enhancing storage settings, and resolving any issues.

Pay close attention to humidity, experiment with pressure, and never forget that a second press might work wonders for you. Take on problems like clothing compatibility and incomplete cure head-on. With these realizations, say goodbye to those bothersome bright spots on black DTF prints and hello to a brand-new age of flawless DTF inventions.


I’ve noticed shiny spots on my black DTF prints. Is this a common issue?

Shiny spots can occur, and while not uncommon, they can be addressed with some adjustments to your DTF printing process.

Could over pressing or under pressing be causing the shiny spots?

It’s a possibility. Evaluating and fine-tuning your pressing technique might help resolve the issue. Experiment with time, temperature, and pressure settings.

How can I refine the curing process to eliminate shiny spots?

Extend curing time and temperature to ensure thorough drying. Pre-powdering on a heated plate for around 10 minutes can also contribute to better results.

Can humidity be a factor in the appearance of shiny spots?

Yes, humidity can play a role. Keep your printing environment dry and consider investigating the timing of powdering and heating the film.

What if I’ve already followed the instructions accurately, and the issue persists?

If you’ve adhered to instructions and still face problems, consider adjusting environmental factors, such as humidity, and explore tweaks in the curing process.

Is it okay to double press or apply more pressure for better prints?

Yes, increasing pressure during pressing and opting for a second round, if needed, can contribute to a more solid transfer of the design onto your garment.

Are Teflon sheets causing unwanted shine on my prints?

Teflon sheets can introduce shine. Consider using alternatives like paper or an extra shirt to maintain the natural finish of your DTF prints.

Does the type of ink, especially white ink, contribute to shiny spots?

White ink, with its glycerin content, demands patience. Ensure it dries adequately before moving on to powdering and curing to prevent hiccups in the printing process.
