Using a stencil: screen printing is ideal for larger designs and high-quality applications
Screen printing is a popular method for printing on plastic, especially for larger designs and high-quality applications. It is a versatile technique that can be used on various surfaces, including plastic, fabric, wood, glass, and more. To get started with screen printing using stencils, you'll need some basic equipment and a few simple steps to follow.
Firstly, choose the right stencil material. Newsprint is a popular choice as it is thin yet strong enough to withstand the ink. You can also use Impress Stencil Film, a durable and flexible plastic film that can be washed and reused. Create your design, leaving white spaces or bridges to hold the stencil together. Then, cut out the design with a craft knife or trace it with a permanent marker if it has multiple components.
Next, prepare your screen. Place your stencil on the screen, ensuring the image is centred. Secure the stencil with low-tack tape, and then apply spray mount adhesive to the front, following the instructions for the specific adhesive you are using. You can also add a border of masking tape at the back of the stencil for added stability.
Now you're ready to start printing! Place your plastic item on a flat surface and position the screen over it. Apply ink to the screen and use a squeegee to push the ink through the mesh and onto the plastic. Apply firm pressure and move the squeegee up and down to clear the screen of ink. Carefully lift the screen and remove your printed plastic item. Set it aside to dry.
Screen printing with stencils is a straightforward process that can be done at home with the right tools and preparation. It's perfect for larger designs as it's less time-consuming than other methods, and the same stencil can be used multiple times. With screen printing, you can achieve high-quality prints on plastic, making it ideal for applications such as packaging, labels, and product graphics.

Inkjet printing: using latex inks and decal sheets or outsourcing for the best quality
Inkjet printers are a more affordable option for printing on plastic than laser printers, but they may not always produce the highest quality prints. When using an inkjet printer, it is important to use the right type of ink and paper. For example, if you want to create your own decals, you will need to use decal film that is specifically designed for use with inkjet printers, such as Experts-Choice® Decal Film. This film is available in clear and white sheets, allowing you to create decals with a transparent or opaque background. You can use your own colour inkjet printer or laser printer to print on the decal film, but be sure to select the correct type of film for your printer. Inkjet printers use liquid inks, so it is important to use decal paper with a special coating that prevents the ink from beading. If you are printing onto plastic, you will also need to choose the right type of plastic for your project, such as PVC, polycarbonate, or PETG, each with its own advantages and disadvantages.
When creating your artwork, you can use computer software, dry transfers, previously printed designs, or even pen and ink. If using colour artwork or colour photos, it is recommended to print them on white decal paper so that the white component is preserved. You can then print your artwork onto the glossy side of the decal paper using a medium resolution setting. After printing, you must apply a thin coat of Microscale Liquid Decal Film to seal the printed image.
If you are looking for the highest quality prints on plastic, you may want to consider outsourcing your printing to a company that specialises in this type of printing. Outsourcing can be more cost-effective than in-house printing, as you don't need to invest in expensive printing equipment and technologies that require frequent repairs. Additionally, printing companies often have high-quality design departments that can create sophisticated designs that may be beyond the capabilities of an internal design team. By outsourcing your printing, you can also save time and focus on your core business operations.
Another option for printing on plastic is to use a 3D printing service. 3D printing is becoming increasingly accessible, with local service providers offering outsourcing services for manufacturing work. This can save on transport costs compared to traditional manufacturing processes done abroad. 3D printing is also environmentally friendly, reducing material wastage and improving fuel efficiency through the use of lightweight parts.
