Basic DTF Printing Terms

The following DTF printing glossary terms cover the foundational terms in the DTF printing process, helping you get started.

How to Use/Maintain

1. DTF Printing

DTF printing, or Direct-to-Film, is a straightforward approach that involves printing designs directly on film and transferring them to cloth using heat.

It is the primary technique employed for custom garment printing without prior treatment—an excellent option for bright, full-color designs.

2. PET Film

A heat-resistant plastic sheet, commonly referred to as PET film, forms the foundation for DTF printing equipment.

Have it facing the matte side up when printing; this will prevent the ink and powder from being retained while it is being handled.

3. Heat Press

Linking printed film to cloth using a controlled temperature and pressure device.

The final transfer depends on this; therefore, adjust temperature and pressure based on your fabric and film type.

4. Curing

Heating the adhesive powder with heat in the ink.

Good curing is essential for longevity and effective transfer; thus, it is crucial.

5. Transfer

The process of heat pressing and glue application of the printed design from PET film onto clothes.

Use a heat press to transfer the design from the PET film onto the garment. 

6. Gang Sheet

A technique incorporating multiple designs on one film.

Best utilized for mass DTF production, it lowers material loss.

7. Hot Peel

Immediately after pressing Hot Peel, you remove the PET film.

Fast but requires exact timing for liquid movements. Ideal for fast workflows. Peel gently after removing the heat press.

8. Cold Peel

Let the PET film cool before removing it; this enhances adhesion and clarity, particularly for intricate patterns.

Peel 15 to 30 seconds after pressing; often, better results are possible.

9. Pre-treatment

Pre-treatment refers to the application of a special chemical before the process. 

Proper pre-treatment is crucial to help the adhesive powder adhere properly. 

10. Peel Test

A peel test is a quality check that ensures the design has adhered perfectly. 

Better adherence requires edge lifting; press for a few seconds more, then softly peel a corner to test. 

Ink & Powder-Related Terms

Inks and powders are essential materials for DTF printing. Choosing the right one ensures long-lasting designs.

How to Use/Maintain

11. DTF Ink

Special pigments made just for DTF. 

Shake the ink bottles before use to prevent pigment from settling. Store away from sunlight.

12. CMYK

Cyan, Magenta, Yellow, Black—the classic squad. Essentially, these four inks are your best bet if you want anything even close to decent color on your shirts.

CMYK inks should be filled and loaded correctly in the printer. 

13. White Ink

This is the secret sauce. Lays down a solid white base, allowing colors to show up (especially on black tees). 

Not suitable for dark shirts. Always start with white, then stack your colors. 

14. Adhesive Powder

Sprinkle this magic dust on your fresh print, then heat it so it melts and adheres your design directly to the shirt.

Always add it carefully without sprinkling too much, which can result in glued prints.

15. Powder Shaker

This shakes the powder for you, making it ready to apply.

Best suited for mass production. 

16. Powder Oven

Old-school but reliable. It bakes that powder in, so your design sticks. 

Perfect for newbies or anyone running a not-so-high-tech setup.

17. Over-Powdering

You apply the powder too heavily, resulting in lumpy prints or items peeling off.

Dust, then tap off the excess before baking—less is more.

18. Under-Powdering

Skimp on powder and your print might flake, peel, or just wash off after one wear.

Check for full coverage. Missed a spot? Hit it again.

19. Powder Shelf Life

Powders that are past their shelf life may not produce a vibrant result. 

Keep it airtight after use and discard if the expiry date has passed.

20. Ink Flow

This is how smoothly ink runs through your printer. If it’s off, expect streaks, faded colors, or prints that don’t exceed expectations.

Show your printer some love—clean it out if you see lines or weird gaps.


Printer and Equipment Terms

The following terms encompass the hardware and software required for successful DTF printing techniques, from start to finish.

How to Use/Maintain

21. DTF Printer

It’s a printer to apply DTF ink on PET film. Some models even come with built-in white ink channels and a heater.

Wipe it down inside and out, keep it dust-free for accurate results.  

22. RIP Software

This software takes your picture and converts it into a format that your printer can use. It controls aspects such as the amount of ink used, the colors displayed, and the sharpness.

Keep your software up to date. Tweak those settings if your prints look wonky or colors are off.

23. Printhead

The business end of your printer that ejects the ink. If it gets clogged, your prints may look rough.

Clean it every day—no joke. Use the auto-clean feature if you’re lazy, but flush it with cleaner if things get gnarly.

24. Nozzle Check

Think of this as a quick test to see if the printhead is doing its job. A destructive pattern means trouble (usually a clog).

Run this test before every print session. See gaps or weird lines? Time to clean the printhead—don’t wait.

25. Print Resolution

Essentially, the sharpness or crispness of your image. Measured in DPI (dots per inch). More DPI = more detail, but also takes forever to print.

Choose your resolution based on what you’re printing—high detail for artwork, and lower for bulk items. Find your sweet spot between quality and speed.

26. Ink Tank

The place where your DTF ink hangs out before making its big debut. Most setups utilize refillable tanks to reduce costs.

Only fill with the correct ink. Clean out the tanks once a week, shake gently before use (no one likes settled sludge).

27. Head Strike

This is where the printhead smacks right into the film—it usually happens if the printhead’s too low or the film’s wrinkled. It can damage your print and your gear.

Always set the right head height. Don’t use curled or bent film. 

28. Film Feed

This is how your PET film moves through the printer. If it’s off, you’ll get smudges, crooked prints, or straight-up jams.

Load the film straight and check the rollers. Then, do a test run before proceeding.

29. Maintenance Routine

Keeps things running smoothly and saves you from expensive repairs.

Create a weekly checklist—clean the printhead, ink lines, sensors, and the entire system. Back up your printer settings just in case.

30. Heating Platform

Some printers have a warm-up feature to dry the ink a bit before you apply the powder. Helps stop smears and makes the powder stick better.

Maintain a reasonable level of heat. Use an infrared thermometer if you want to be extra cautious.


Design & Output Terms

In this section, we will cover terms that are crucial for a successful DTF transfer process, from creating to finalizing your DTF designs.

How to Use/Maintain

31. Ghosting

This is the faint double image after pressing, like a shadow. Usually happens when the film slides around during the heat press.

Just tape the film down tight so it doesn’t move during the process. 

32. Cracking

Usually, it means your powder didn’t cure properly, or the powder itself was of poor quality.

Stick with steady heat and time. 

33. Peeling

When your design starts lifting off the shirt—that’s peeling. Uneven pressure, excessive or insufficient powder, or inadequate pressing time can all disrupt the process.

Make sure the pressure’s even and you’re pressing long enough. Don’t rush it.

34. Staining

Random weird colors or splotches on the fabric after pressing. It could be a dirty film, the heat cranked up too high, or just the ink going wild.

Keep your film clean and control the heat. 

35. Banding

Those horizontal lines across a print? Classic banding. It’s what you get when the nozzles are clogged or your printer settings are whack.

Run a nozzle check and adjust your settings as needed. Don’t just hope for the best.

36. Moisture Control

Humidity's the sneaky villain here. It messes with powder and film, making prints unpredictable.

Store everything somewhere dry. Silica packs are best for this purpose. 

37. Washing Instructions

Want those prints to last? Flip garments inside out, wash in cold water, skip the bleach, and keep the dryer on low.

Proper care = prints that don’t look like they went through a war.

38. Quality Control

Inspect every print thoroughly before and after pressing. Smudges, crooked designs, patchy ink—catch ‘em before shipping.

Double-check everything before shipping. 

39. Pressure Setting

Pressure setting defines the print quality. 

Check for optimal pressure, typically around 25-35 PSI (1.7-2.4 kg/cm²).

40. Consistency

The not-so-secret ingredient to nailing DTF printing every single time.

Use settings that work, stick with good materials, and keep up with maintenance.
