If you're looking to take your screen printing game to the next level, then screen printing on plastic could be just the challenge you need. With its smooth surface and endless creative possibilities, plastic is a popular choice for everything from promotional items to packaging. But before you dive in, here's everything you need to know to get started.
First, you'll need to choose the right type of plastic for your project. Some plastics, like polyethylene and polypropylene, have a low surface energy which makes them difficult to print on. Others, like polycarbonate and acrylic, have a higher surface energy and are easier to work with. You'll also need to consider the color and thickness of the plastic, as these factors can affect your printing results.
Next, you'll need to prepare your artwork. When designing for plastic, it's important to keep in mind that ink may appear differently on plastic than it does on paper or fabric. Bright colors tend to work well, as do bold, simple designs. You may also need to adjust your screen mesh and ink viscosity to achieve the best results.
Once you have your artwork and plastic in hand, it's time to set up your screen printing plastic station. Make sure you have a clean, flat surface to work on and that your screen is properly tensioned. Apply a thin layer of emulsion to your screen and allow it to dry completely before exposing your design.
When it comes time to print, take your time and work carefully. Plastic can be slippery, so you'll need to use a light touch to ensure your print doesn't smudge or shift. Consider using a low-tack tape to hold your plastic in place, and experiment with different types of ink to find the one that works best for your project.
With a little practice, screen printing on plastic can be a rewarding and profitable venture. Whether you're printing on cups, bags, or other plastic products, the possibilities are endless.
