How to Heat Press Our DTF Prints | Drop Of Colour
Press It Right. Peel It Clean. Make It Last.
Ordering a high-quality DTF transfer is only the first part of creating a professional printed garment. The final result also depends on how the transfer is applied.
Incorrect temperature, insufficient pressure, trapped moisture or peeling the carrier film incorrectly can cause a DTF print to lift, bubble or fail to stick properly.
This guide explains how to heat press Drop Of Colour DTF prints onto T-shirts, hoodies, workwear, sportswear and other suitable garments.
Recommended DTF Heat Press Settings
Use the following settings as a general starting point for Drop Of Colour DTF transfers:
Temperature: 150°C to 160°C
Pre-press time: 3 to 5 seconds
Main press time: 12 to 15 seconds
Pressure: Medium-to-firm
Peeling method: Follow the instructions supplied with your order
Finishing press: 5 to 8 seconds
These settings are a starting point. Different heat presses, fabrics and garment coatings may require slight adjustments.
Always test one garment before beginning a large production run.
What You Need Before Heat Pressing
Before starting, make sure you have the correct equipment and a clean working area.
You will need:
A reliable heat press
Your Drop Of Colour DTF transfer
A clean and suitable garment
A lint roller
A ruler or garment alignment tool
Heat-resistant tape when required
A pressing pillow or suitable foam pad
Silicone paper, parchment paper or a suitable finishing sheet
A household iron is not recommended for professional DTF application.
A household iron normally cannot provide consistent temperature and pressure across the entire design. This can cause sections of the transfer to stick while other sections remain loose.
Important: Always test heat-sensitive, waterproof, coated or synthetic garments before completing the full order. Some materials may scorch, melt, discolour or develop permanent press marks.
Step 1: Inspect the Garment
Inspect the garment before placing it onto the heat press.
Check for:
Dirt
Oil
Lint
Loose fibres
Wrinkles
Moisture
Stains
Buttons
Zippers
Thick seams near the print area
Use a lint roller to remove dust, loose fibres and pet hair from the pressing area.
Lint trapped underneath the transfer can create bumps, weak spots or visible marks in the finished print.
Check the Garment Care Label
Read the garment care label before applying heat.
Some polyester, waterproof and coated garments may require a lower temperature or shorter pressing time.
When you are unsure, test the garment before completing the customer’s full order.
Step 2: Prepare Your Heat Press
Switch on the heat press and allow it to reach the required temperature.
Do not begin pressing immediately when the display reaches the selected temperature. Allow the platen a little extra time to heat evenly across the entire surface.
Check that the lower platen is:
Clean
Flat
Secure
Free from adhesive residue
Free from damaged padding
Free from old ink or transfer marks
The upper platen should also be clean and free from any residue that could transfer onto the garment.
💡 Drop Of Colour Pro Tip: The temperature displayed on your heat press may not always match the actual platen temperature. If transfers repeatedly fail in the same area, check the platen for cold spots or inaccurate temperature readings.
Step 3: Set the Correct Pressure
Pressure is one of the most important parts of applying a DTF transfer.
Heat activates the adhesive, while pressure pushes the melted adhesive into the fibres of the garment.
If the pressure is too light, the print may:
Remain on the carrier film
Lift around the edges
Stick in some areas but not others
Peel after washing
If the pressure is too heavy, it may:
Leave visible press marks
Damage heat-sensitive fabric
Flatten thick garments excessively
Push adhesive beyond the edge of the design
Use medium-to-firm pressure as a general starting point.
On a manual heat press, you should feel firm resistance when closing the handle. The press should not close without effort, but it should not need to be forced dangerously.
Step 4: Pre-Press the Garment
Place the garment flat on the lower platen.
Pre-press the print area for approximately 3 to 5 seconds.
Pre-pressing helps to:
Remove trapped moisture
Flatten wrinkles
Warm the garment fibres
Create a smooth pressing surface
Improve the final bond
Fabric can hold moisture even when it feels dry.
When the heat press closes, that moisture turns into steam and can push upward against the adhesive. This may cause bubbling, pitting, lifting edges or patchy adhesion.
Important: Never skip the pre-press during humid weather or when garments have been stored in a cold or damp area.
Step 5: Position the DTF Transfer
Place the DTF transfer onto the garment with the printed side facing the fabric and the carrier film facing upward.
Take your time and make sure the design is positioned correctly before pressing.
Check that:
The transfer is straight
The design is centred correctly
The printed side is facing the garment
The transfer is not upside down
The design is positioned at the correct height
No seams or zippers are lifting the print area
General DTF Print Placement
Full-front print: Position the design below the collar with enough space between the collar and the top of the artwork.
Left-chest logo: Position the logo over the wearer’s left chest rather than directly between the collar and sleeve.
Back print: Position the artwork below the back collar and check that it is centred.
Sleeve print: Keep the design away from thick seams and folds.
Neck label: Position the transfer inside the garment below the collar seam.
Use a ruler, T-shirt alignment guide or other garment-positioning tool when pressing several garments that need consistent placement.
💡 Drop Of Colour Pro Tip: Fold the garment lightly from side to side and pre-press it for one or two seconds to create a temporary centre line. You can also fold the carrier film gently to find the centre of the transfer without creasing the printed design.
Step 6: Check for Seams, Zippers and Buttons
The heat press must apply even pressure across the entire transfer.
If a collar, seam, zipper, pocket or button sits higher than the print area, the platen may rest on that raised section instead of pressing the design evenly.
This can cause one part of the transfer to stick while another section remains loose.
Use a Pressing Pillow
Place a heat-resistant pressing pillow or suitable foam pad underneath the print area.
The seams and raised sections can sink into the pillow while the design remains elevated and flat.
Pressing pillows are useful for:
Left-chest logos
Zipped hoodies
Pockets
Sleeve prints
Children’s garments
Workwear
Garments with buttons
Step 7: Complete the Main Press
Once the transfer is positioned correctly, close the heat press.
As a general starting point, press at approximately 150°C to 160°C for 12 to 15 seconds using medium-to-firm pressure.
Keep the garment and transfer still throughout the pressing cycle.
Do not:
Open the press before the timer ends
Move the transfer during pressing
Allow the garment to bunch or fold
Press over thick seams without support
Use a dirty protective sheet
When the timer ends, open the heat press smoothly.
Avoid pulling or dragging the garment while the adhesive is still hot.
Step 8: Peel the Carrier Film Correctly
DTF carrier films can be:
Hot peel
Warm peel
Cold peel
Always follow the peeling instructions supplied with your Drop Of Colour transfer.
Hot-Peel Film
Hot-peel film is removed shortly after opening the heat press.
Waiting too long may make the carrier film more difficult to remove.
Warm-Peel Film
Allow the transfer to settle briefly before peeling.
The transfer should be warm rather than extremely hot or completely cold.
Cold-Peel Film
Allow the garment and transfer to cool before removing the carrier film.
Peeling too soon can cause sections of the design to remain on the carrier.
💡 Drop Of Colour Pro Tip: Peel the carrier slowly and smoothly at a low angle across the garment. Avoid pulling the carrier straight upward.
What to Do if the Design Starts Lifting
If part of the design starts lifting with the carrier film:
Stop peeling immediately.
Place the carrier film back into position.
Cover the transfer with a suitable protective sheet.
Press it again for a few seconds.
Allow it to reach the correct peeling temperature.
Try peeling again slowly.
Do not continue pulling when the design is visibly lifting.
Step 9: Complete the Finishing Press
After removing the carrier film, cover the exposed design with silicone paper, parchment paper or a suitable finishing sheet.
Press the design again for approximately 5 to 8 seconds.
The second press is also called:
The finishing press
The post-press
The final press
The finishing press helps to:
Strengthen the adhesive bond
Embed the transfer into the garment fibres
Improve the print texture
Reduce lifting around the edges
Improve wash durability
Important: Do not skip the finishing press. A transfer may appear secure after peeling but still have a weaker bond if the final press is not completed.
Choosing a Finishing Sheet
Different finishing sheets can slightly change the appearance and feel of the completed print.
They may produce:
A smooth finish
A matte finish
A slightly glossy finish
A more fabric-like texture
Always use a clean finishing sheet that is suitable for heat pressing.
A dirty or damaged finishing sheet can transfer marks, adhesive or ink onto the garment.
Step 10: Allow the Garment to Cool
After the finishing press, place the garment on a clean, flat surface and allow it to cool.
Do not immediately fold, stack or package the garment while the transfer is still hot.
A hot transfer may stick to:
Another garment
Plastic packaging
A printed surface
Another section of the same garment
Allow the garment to cool completely before folding, packing or supplying it to the customer.
Pressing Different Garment Types
100% Cotton
Cotton can hold moisture and may shrink slightly under heat.
Pre-press the garment thoroughly and use the standard settings as your starting point.
Polyester
Polyester may scorch, develop press marks or experience dye migration.
Test the garment first and consider using a lower temperature or shorter pressing time when necessary.
Cotton-Polyester Blends
Blended garments vary according to their fibre percentages.
Use the standard settings as a starting point and test one garment before completing the full order.
Hoodies
Hoodies may have thick seams, pockets, drawstrings and zippers that cause uneven pressure.
Use a pressing pillow and make sure the print area is flat.
Workwear
Heavy fabrics, coatings and thick seams may affect transfer adhesion.
Test the garment and adjust the pressure carefully.
Sportswear
Stretch fabrics and synthetic fibres may be sensitive to heat.
Use cautious settings and confirm that the garment can handle the required temperature.
Tote Bags
Handles and seams may prevent the heat press from applying even pressure.
Move the handles away from the print area and place a pressing pad inside the bag.
Waterproof or Coated Garments
The coating may resist the adhesive or become damaged by heat.
Always complete a test before producing the full order.
Common DTF Heat Press Problems
The Design Remains on the Carrier Film
Likely cause: Insufficient heat, pressure or pressing time.
Solution: Place the carrier back down and press the transfer again for a few seconds using firm, even pressure.
The Edges Lift During Peeling
Likely cause: The carrier was peeled at the wrong temperature or the pressure was too light.
Solution: Stop peeling, repress the transfer and confirm the correct peeling method.
The Print Peels After Washing
Likely cause: Weak initial adhesion, incorrect heat settings or no finishing press.
Solution: Verify the heat press temperature and always complete the second press.
Bubbles Appear in the Print
Likely cause: Moisture was trapped inside the garment.
Solution: Increase the pre-press time and make sure the garment is dry.
Only Part of the Print Sticks
Likely cause: Uneven pressure, a thick seam or a cold spot on the heat press.
Solution: Use a pressing pillow and inspect the heat press platen.
A Rectangle Appears Around the Transfer
Likely cause: Excessive heat, excessive pressure or a heat-sensitive garment.
Solution: Reduce the heat or pressure and test the garment before pressing another item.
The Garment Changes Colour
Likely cause: Scorching or dye migration.
Solution: Reduce the temperature or pressing time and test a spare garment.
The Design Looks Too Shiny
Likely cause: The finishing sheet or pressing pressure changed the surface of the design.
Solution: Test another finishing sheet and reduce the pressure slightly.

Frequently Asked Questions
What temperature should I use for Drop Of Colour DTF prints?
Approximately 150°C to 160°C is a suitable general starting range. Always follow the instructions supplied with your order and test heat-sensitive garments first.
How long should I press a DTF transfer?
Approximately 12 to 15 seconds is a general starting point for the main press. Complete a second finishing press for approximately 5 to 8 seconds after removing the carrier film.
What pressure should I use?
Use medium-to-firm, even pressure. Pressure that is too light can prevent the adhesive from bonding correctly with the garment fibres.
Do I need to pre-press the garment?
Yes. Pre-pressing for 3 to 5 seconds removes moisture, flattens wrinkles and warms the garment before the transfer is applied.
Do I need to press the print a second time?
Yes. The finishing press helps strengthen the adhesive bond, improve the print texture and increase wash durability.
Should I peel the DTF transfer hot or cold?
Follow the instructions supplied with your order. Different DTF carrier films may be hot peel, warm peel or cold peel.
Why is my DTF transfer not sticking?
The most common causes are insufficient heat, pressure that is too light, trapped moisture, uneven pressure or peeling the carrier at the wrong temperature.
Can I use a household iron?
A heat press is strongly recommended. A household iron does not normally provide consistent heat and pressure across the complete transfer.
Can I press DTF transfers onto polyester?
DTF transfers can be applied to many polyester garments, but polyester can be sensitive to heat and dye migration. Test the garment first and adjust the settings when necessary.
Get Professional Results With Every Press
Professional DTF printing still requires correct application.
The best results come from controlling the four main parts of the process:
Temperature
Pressure
Pressing time
Peeling method
Do not change every setting at the same time when troubleshooting.
Adjust one setting, complete another test press and check the result. This will help you identify the actual cause of the problem.
Once you understand your heat press and follow a consistent process, you can achieve strong, professional and repeatable DTF prints.
