Shrink film, often known by the brand name Shrinky Dinks, is a crafter's dream. This magical material allows you to print or draw a design, cut it out, and then bake it in the oven, where it shrinks down to a small, hard plastic charm. It’s perfect for creating custom keychains, jewelry, zipper pulls, and unique gift tags.
While you can draw on shrink film with permanent markers, printing directly onto it opens up a world of creative possibilities. You can use intricate digital designs, photographs, or any image you can find online. However, getting a perfect print requires a few specific steps and materials.
This guide will walk you through everything you need to know about how to print on shrink film. We'll cover the right type of film to buy, how to prepare your printer and designs, and the step-by-step process for printing, cutting, and baking your creations for a professional-looking finish every time.
Shrink film is a special type of plastic sheet made from polystyrene. When heated, the plastic shrinks significantly and becomes thicker and more rigid. Before heating, the sheets are flexible and can be cut with scissors or a craft knife.
There are several types of shrink film available, but not all are suitable for printing. The most important distinction is between regular shrink film, which is best for drawing, and printable shrink film, which is specifically designed to be used with an inkjet printer. Printable versions have a special matte or rough coating on one side that absorbs the printer ink and prevents it from smudging.
When you're shopping for materials, make sure you purchase "printable shrink film" or "inkjet shrink film." Using regular, non-printable film in your printer can lead to messy, smeared ink and might even damage your equipment.
Before you get started, gather the following materials. Having everything ready will make the process smooth and enjoyable.
Printable Shrink Film: Choose a brand that is compatible with inkjet printers. They often come in various colors like white, clear, or frosted.
Inkjet Printer: You must use an inkjet printer. Laser printers generate heat that can melt the shrink film inside the machine, causing serious damage.
Computer and Design Software: Use any program you're comfortable with to create or edit your designs, like Canva, Adobe Photoshop, or even Microsoft Word.
Scissors or Craft Knife: For cutting out your printed designs.
Baking Sheet: To place your shrink film pieces on for baking.
Parchment Paper or Aluminum Foil: To line the baking sheet and prevent the film from sticking.
Oven or Toaster Oven: For the shrinking process.
Hole Punch (Optional): If you plan to make keychains, charms, or tags.
Sealant (Optional): A clear acrylic spray or resin can protect the finished pieces.
Follow these instructions carefully to achieve the best results with your shrink film projects.
First, decide on the images you want to print. You can create your own digital art, use photos, or find designs online. Keep in mind that the shrink film will shrink to about 20-50% of its original size, and the colors will become much more vibrant and concentrated after baking.
To account for this, you'll need to adjust your images. Lighten the colors in your design software by reducing the saturation or opacity by about 50%. What looks pale and washed out on the screen will appear bright and bold on the final product. If you skip this step, your baked pieces may look too dark.
Also, be mindful of the final size. If you want a keychain that's one inch tall, you'll need to print it at a much larger size. Check the instructions on your shrink film package, as it will tell you the exact shrink ratio.
Load a single sheet of printable shrink film into your inkjet printer's paper tray. It's crucial to identify the printable side of the film. This side usually has a rougher, matte texture, while the other side is smooth and glossy. The ink needs to go on the rough side to be properly absorbed.
Next, adjust your printer settings. In the print dialog box, select a setting for photo paper or glossy paper. This tells the printer to use more ink and print at a higher quality, which is ideal for the non-porous surface of the shrink film. Choosing a "plain paper" setting may result in a faint or incomplete print.
Once your printer is ready, send your lightened designs to print. It’s a good idea to print a single test sheet first to see how the colors turn out and to ensure you have the sizing right.
After printing, carefully remove the sheet from the printer without touching the inked areas. The ink will still be wet and can easily smudge. Set the sheet aside on a flat surface and let it dry completely. Drying time can vary depending on your printer and the humidity, but allow at least 15-30 minutes. Some crafters even let it dry for a few hours to be safe.
Once the ink is dry, use sharp scissors or a craft knife to cut out your designs. If you want a clean border, leave a small white or clear edge around the image.
If you're making a keychain, charm, or tag, now is the time to use a hole punch. The hole will also shrink in the oven, so make sure it's large enough for your intended use. A standard 1/4-inch hole punch works well for most projects.
Preheat your oven or toaster oven according to the package instructions, usually around 300-350°F (150-175°C). Line a baking sheet with parchment paper or aluminum foil.
Place your cut-out shrink film pieces on the prepared baking sheet, leaving some space between them. Make sure the printed side is facing up.
Put the baking sheet in the preheated oven and watch the magic happen! The pieces will curl up, shrink, and then flatten out again. This process usually takes only 1-3 minutes. Keep the oven light on and watch closely, as over-baking can cause the pieces to warp.
As soon as the pieces have flattened out, carefully remove the baking sheet from the oven. If any of the pieces are still slightly curled, you can flatten them by pressing down on them with a spatula or another flat object while they are still hot. Work quickly, as the plastic hardens in seconds.
Let the pieces cool completely, which only takes a minute or two. Once cooled, your shrink film creations are finished! If you want to protect the printed surface from scratches or water, you can apply a clear sealant. An acrylic spray sealer or a thin coat of UV resin will create a durable, glossy finish.
Printing on shrink film is a fun and rewarding way to turn digital designs into tangible, custom accessories. While it might take a little practice to get the colors and sizes just right, following these steps will set you up for success. By choosing the right materials and carefully preparing your designs and printer, you can create beautiful, professional-looking pieces that are perfect for gifts, jewelry, or just for fun.
