What is UV DTF? What does UV DTF mean?

UV DTF, short for “Ultraviolet Direct to Film,” represents a cutting-edge sticker printing method. This technique employs UV-curable inks to directly print designs onto a specialized film, which can subsequently be applied onto different surfaces. Essentially, UV DTF integrates UV printing and DTF (direct-to-film) printing technologies. It functions as a form of transfer printing, utilizing Film A, such as PET film in DTF printing, as the carrier for designs, but unlike traditional methods, it employs UV light to solidify the ink instead of relying on hot melt adhesive powder and heat for the process’s completion.

What is uv dtf cup wraps?

UV DTF cup wraps are cup wraps created with UV DTF(Direct To Film) printing technique. Instead of using heat transfer to apply designs onto cups, UV DTF cup wraps usually work like normal stickers that require no extra devices for heat transfer process and users could wrap the sticker onto cups and peel off the covering film with bare hand. What’s more, UV DTF printer would also do varnish printing simultaneously while conducting color or white printing. This unique process not only makes the color looks more vibrant but also adds extra embossed effect which is perfect for logo or sticker printer in many occastions.

How to make UV DTF cup wraps, transfers and stickers?

To create UV DTF transfers, stickers, or wraps for cups and other drinkware, you’ll need a few essential items to get started:

  • UV DTF Printer: A special printer equipped with an LED UV lamp to print designs onto substrate or UVDTF transfer film.
  • Laminator: The machine to adhere the “A” film to the “B” film. (There are also printers like Aries 113 trying to make things simple and having printing and laminating done in one compact device.)
  • Film A: Where the designs are printed on and it is also the back of the design.
  • Film B: The film to cover the designs during curing process (also the front cover on design).
  • UV Ink: UV light curing ink includes CMYK+W and varnish.

Once you have everything prepared, it’s time to begin printing UV DTF transfers. Below is a step-by-step guide to help you through the process:

  • Create Design: While prepare the design for transfer, it is recommended to use high-resolution vector images that can be scaled infinitely without losing quality and is ideal for printing.
  • Design Creation: Use graphic design software like Adobe Photoshop or Illustrator to create your cup wrap design. Ensure that the design dimensions match the size of the cup you’re printing for.
  • Prepare the UV DTF Film: Before loading the film onto the printer, inspect the roll for any wrinkles, creases, or damage .Smooth out any imperfections to prevent printing issues and ensure consistent results.
  • Load UV DTF Film: Load a roll of UV DTF film onto the printer’s roll holder. Align the leading edge of the film roll with the printer’s roll holder or spindle. Make sure the film is centered and properly seated to prevent misfeeds or skewing during printing. Ensure that the film is loaded without any overlaps or twists. Overlapping film layers can cause printing errors and affect the quality of the final prints. If your printer has sensors for detecting film position or end detection, double-check their alignment before loading the film. Misaligned sensors can lead to inaccurate feeding and registration issues.
  • Adjust Printer Settings: Set up the printer according to the specifications provided by the manufacturer. This includes adjusting print settings such as resolution, ink density, and color management.
  • Perform Test Prints: Before printing your final designs, perform test prints to verify that the film is loaded correctly and the printer is functioning properly. Adjust settings as needed to optimize print quality.
  • Print the Design: Send the cup wrap design file to the UV DTF printer. Make sure the printer is calibrated correctly to ensure accurate color reproduction and registration. Print the design onto the UV DTF film.
  • Apply Adhesive: Apply an adhesive layer to the back of the film A using a heat press or laminating machine (For DTF Station printer, the laminating machine is integrated into the UV DTF printers, so no extra laminating is required ). Make sure the adhesive is evenly applied across the entire surface.

How to apply UV DTF cup wraps?

Applying UV DTF cup wraps to your glass tumblers, jars, mugs or cups could also be a very simple process and following is a quick guide to accomplish the work:

  • Step 1: Thoroughly wash and clean the cup, then dry it with a cloth.
  • Step 2: Cut out the UV DTF stickers according to your desired design.
  • Step 3: Remove a 1-inch width of backing from the edge of the UV sticker to expose the adhesive area.
  • Step 4: Carefully position the adhesive area on the cup, ensuring the design is straight.
  • Step 5: Roll the cup to gradually remove the backing of the sticker, ensuring the adhesive securely adheres to the cup until the entire wrap sticks.
  • Step 6: Apply pressure to the sticker for 3-5 minutes using your palm to activate the adhesive with body heat, facilitating easier peeling.
  • Step 7: Slowly peel off the cover sheet, gently pressing down any lifted parts and re-peeling if necessary.
