There are many ways to transfer images onto a plastic cup. Some methods involve using decal paper, Mod Podge, gel medium, or contact paper. For decal paper, you print your desired image on waterslide decal paper, cut it out, and wrap it around the cup before applying heat. Mod Podge is a simple and affordable method where you apply a layer of Mod Podge to the cup, place the printed image on top, and smooth out any bubbles. You can also use gel medium, where you brush the medium onto the image and lay it onto the cup before burnishing. Another option is to use contact paper, where you print your design, place it face down on the contact paper, rub to transfer the design, and then stick the contact paper onto the cup.

What You'll Learn
Print image on decal paper
One of the easiest ways to put images on a cup is by using printable decal paper. Waterslide decal paper is a special material that allows you to print an image at home and transfer it to your cup. You can use any image you like, but clear images with less detail tend to transfer better.
First, select the image you want to use and upload it to a program of your choice. You can use any program that allows you to edit, resize, and print images, such as Photoshop, Word, Silhouette Studio Software, Design Space, or Inkscape. Resize the image to fit the cup, leaving a small border of about 1 inch (2.5 cm) around it.
Next, print the image onto the waterslide decal paper. Make sure to print on the glossy side of the paper and set your printer settings to "glossy photo paper." If you're using an inkjet printer, remember to seal your inked image after printing. You can do this by using an acrylic-based clear spray paint and applying three coats, allowing each coat to dry completely before applying the next.
Once your image is printed and sealed, cut it out, leaving the small border around it. Now, you're ready to apply the decal to your cup. Carefully place the decal on the cup, smoothing out any bubbles or wrinkles.
For a more durable and professional-looking finish, you can use a method called sublimation printing. This process requires a sublimation printer, sublimation ink, and sublimation paper. After printing your image, wrap it tightly around the cup and secure it with heat-resistant tape. Place the cup into a mug press or wrap it with a heat blanket, applying heat at around 400°F for 3-5 minutes. Finally, carefully remove the cup from the press and peel off the sublimation paper to reveal your transferred image.

Sublimation printing
To start, you will need a sublimation printer, sublimation ink, and sublimation paper. Print your chosen image, mirrored, onto the sublimation paper using the printer and ink. Before printing, ensure your image is in reverse, as it will transfer that way. Cut the image to size, allowing for a small border to ensure complete coverage of the cup.
Next, wrap the image around the cup, securing it with heat-resistant tape. This tape will prevent the image from shifting during the heat transfer process. Place the cup into a mug press or wrap it with a heat blanket. Apply heat at around 400°F for 3-5 minutes, following the specific instructions provided by your press manufacturer.
Once the heat application is complete, carefully remove the cup from the press and peel off the sublimation paper to reveal your transferred image. The sublimation process transforms the ink into gas, allowing it to penetrate the plastic and create a lasting image. This method results in vibrant, full-colour designs that become a permanent part of the cup, making them long-lasting and dishwasher-safe.

Mod Podge method
Mod Podge is a popular method for transferring images to plastic cups, among other things. It is a unique glue, sealer, and finish that can be used to transfer images to a variety of surfaces, including plastic. Here is a step-by-step guide on how to transfer an image to a plastic cup using the Mod Podge method:
Step 1: Prepare the image
Choose the image you want to transfer and size it to fit the plastic cup using photo editing software. It is important to note that the image will appear reversed once transferred, so be sure to mirror the image before printing. Also, make sure to print the image on plain paper, as photo paper will not work for this project.
Step 2: Apply Mod Podge to the image
Once you have cut out your image, apply a thick layer of Mod Podge to the front of the image using a sponge or foam brush. Make sure the layer is thick enough so that you cannot see the image through it.
Step 3: Place the image on the cup
Carefully place the image onto the plastic cup, exactly where you want it to go. Use a roller or a smooth, hard object (such as a credit card) to flatten the image and remove any bubbles or bumps.
Step 4: Let it dry
This is the most challenging part of the process—waiting for the Mod Podge to dry. Leave the project untouched for several hours or even overnight to ensure that the Mod Podge is completely dry.
Step 5: Remove the paper
Once the Mod Podge is dry, it's time to remove the paper. Dampen a sponge and gently rub the paper in a circular motion until it starts to come off. Continue until all the paper is removed, and you are left with your transferred image on the plastic cup.
Step 6: Seal the image (optional)
If desired, you can apply a final coat of Mod Podge, gloss varnish, or sealant spray to seal and protect your image. This step is optional but will help to ensure the longevity of your project.
And that's it! You have successfully transferred an image to a plastic cup using the Mod Podge method. This technique can also be used on a variety of other surfaces, including wood, glass, canvas, and fabric.

Use contact paper
Using contact paper is a great way to transfer images onto a plastic cup. Here is a step-by-step guide on how to do it:
Prepare the Image
First, you need to create or choose the image you want to transfer. You can use a computer program to design your image or transfer a photo. It is important to resize the image to fit the cup, leaving a small border. If you are using words, images with higher contrast will transfer better. Once you are happy with the size and design, print your image onto regular printer paper.
Contact Paper Setup
Now, you will need to get your contact paper ready. Take a sheet of clear contact paper and carefully peel off the backing to expose the adhesive side. Place the contact paper on a flat surface with the adhesive side facing up.
Transfer the Image
Place your printed image face down onto the adhesive side of the contact paper. Ensure that the image is positioned correctly and rub over it with your finger to transfer the image. You can use simple tools like a bone folder, the back of a spoon, or a plastic handle to help with this process. Go over the image a few times, especially in areas with more ink, to ensure a good transfer.
Trim and Apply to Cup
After the image has been transferred to the contact paper, trim away any excess white paper around the design. Cut the contact paper to size, making sure the image will fit nicely onto your cup. Now, carefully pick up the contact paper and align it against the cup's side, with the adhesive side still facing up. Smooth out any air bubbles or wrinkles, and you're done!
Drying and Removal of Contact Paper
Allow the contact paper to dry completely before removing it. The adhesive will become stickier as it dries, helping the image stay in place. Once dry, you can carefully peel off the contact paper to reveal your transferred image on the cup. If needed, dip your fingers in water and rub the edges of the paper to remove it more easily.
With these steps, you can successfully transfer images onto plastic cups using contact paper. Enjoy customising your cups with your favourite designs and photos!

Acrylic gel transfer
To begin the acrylic gel transfer process, take your chosen image and apply a generous coat of acrylic gel to it. You can use any clear acrylic medium, such as Golden Extra Heavy Gel or Liquitex's Gloss Heavy Gel Medium. Make sure to cover every part of the image that you want to transfer. Once the gel is dry, cut away any unused portions of the paper or image.
Next, prepare your plastic cup by ensuring its surface is clean and dry. Apply another coat of gel to the image and, while the gel is still wet, place the image face down on the cup. Use your hand or a burnishing tool to rub the back of the paper firmly, creating a tight seal. Allow the gel to dry completely, preferably overnight.
After the gel is completely dry, it's time to soak the paper in lukewarm water to dissolve it. Fill a tray, dish, or bucket with lukewarm water—be careful not to make it too hot, as it may soften the acrylic, and not too cold, as it will be difficult to dissolve the paper. Soak the paper for around 10 to 15 minutes. Gently scrub the paper fibres off the gel, then give it a final rinse in fresh water to remove any remaining residue. Allow the gel to dry completely.
Once dry, your transferred image will be ready to use. You can add acrylic paint during the process to incorporate colour. Keep in mind that the transferred image will be translucent, so the colour of the cup or any underlying layers will show through. Additionally, you can trim the transferred image to avoid any "halo" effect created by the thick acrylic gel.
