What You'll Learn
Inkjet printing on plastic
There are a few things to consider when inkjet printing on plastic. Firstly, it is important to choose the right type of ink. Solvent-based inks, for example, can provide a waterproof and scratch-proof print on plastic, but they are not compatible with regular inkjet printers. Instead, they are typically used on large-format inkjets. Regular inkjet printers that use water-based inks are not suitable for printing on plastic as the ink will not dry and will smudge. Some sources suggest that it may be possible to use a regular consumer inkjet printer with non-smudging ink, such as latex ink, but the quality may be poor. For this reason, it is generally recommended to outsource printing to a company that specializes in printing on plastic, especially if you require a small number of items.
Another consideration is the type of plastic being used. There are many different types of plastics, each with unique chemical structures and physical properties. The best ink formula for printing on plastic will depend on the specific material's makeup. For example, the ink used to mark PVC pipes would differ from the ink used on flexible LDPE wrap due to differences in surface energies and properties.
Additionally, pre-treatment of the plastic surface may be required to ensure proper ink adhesion. This could involve using a primer wipe or other pre-treatment methods such as flame, corona, or UV curing. The specific pre-treatment method will depend on the intended use of the printed plastic item.

Laser engraving
When it comes to laser engraving plastic, it is important to note that not all types of plastics are suitable. Some plastics are safe for laser processing, while others may release toxic gases or harmful fumes that can be hazardous to health. For example, plastics such as polyvinyl chloride (PVC), ABS, and polycarbonate should be avoided as they emit toxic and carcinogenic fumes, including hydrochloric acid, vinyl chloride, ethylene dichloride, dioxin, and cyanide gas. On the other hand, materials like acrylic, fluoropolymers, Mylar, and polyimide are suitable for laser engraving as they do not emit hazardous gases or particles.
To get started with laser engraving plastic, you will need to select the right type of plastic and the appropriate laser machine. CO2 laser machines are commonly used for plastic cutting and engraving and should have at least 40 watts of power for optimal results. Diode laser cutters are more affordable but have limited capabilities as they can only cut and engrave opaque plastic. Infrared lasers are also a good choice for engraving plastics, creating sharp and high-quality engravings.
Once you have selected the appropriate laser machine, you can prepare your design. You can either create your own design or choose from a library of free laser engraving designs available online. After importing your design into the laser engraving software, you can adjust parameters such as power, speed, and focus to achieve the desired depth and clarity of your engraving. It is recommended to perform a test on a scrap piece of the same material to fine-tune the settings before proceeding with your final product.

Wax thermal transfer
The wax ribbons come in different types, such as simple wax, wax-resin, and pure resin, each offering varying levels of durability and image quality. Simple wax ribbons are typically used for simple transfers on paper, while resin ribbons provide greater durability and resistance to abrasion. Wax-resin compounds offer a balance between the two, producing more refined images with increased durability compared to plain wax.
The thermal transfer printer uses a microprocessor-controlled printhead to determine which heating pins need to be activated to form the desired image. This process involves rapidly heating and cooling the selected pins against the wax ribbon, causing the wax to melt and transfer onto the substrate. The printer can be adjusted to suit the material being printed on and the desired image quality.

Digital printing pros and cons
Digital printing has gained popularity in the printing industry, offering a more efficient and cost-effective alternative to traditional offset printing. This method involves using high-tech machines like laser and inkjet printers to apply ink and toner directly onto paper or other materials. Here are some pros and cons of digital printing to consider:
Pros of Digital Printing:
- Cost-effective for small projects: Digital printing is ideal for small print runs as it eliminates the need for custom plates, making it cheaper than offset printing.
- Fast turnaround: With digital printing, there is no need to wait for custom plates, resulting in quicker print turnaround times.
- Flexibility: Digital printing allows for easy adjustments to the image during the printing process. It also accommodates variable data printing, such as custom codes and addresses.
- Short setup times: Digital presses have minimum setup requirements, making them suitable for short print runs and accommodating last-minute changes.
- Customization: Digital printing is perfect for customized or variable data jobs, offering greater personalization options.
- Material options: Digital printing can be used on a wide range of materials, including paper, plastic sheets, plastic film, and compostables.
Cons of Digital Printing:
- Expensive for large orders: Digital printing costs add up for large print runs, as the cost per print remains the same regardless of quantity.
- Image quality: Digital prints may not be as crisp as offset prints, and inkjet printing may smear in rare cases.
- Limited finish options: Digital printing has restricted finish options and printing effects, and some advanced coatings and techniques are not possible.
- Colour limitations: Digital presses may struggle to accurately reproduce certain colours, especially light colours or whites on dark papers.
- Not suitable for large sheets: Offset printing is generally preferred for larger sheets of paper.
Digital printing has revolutionized the industry, particularly for short print runs and customized projects. However, it also has some limitations, especially when compared to the advantages of offset printing for large-scale projects. Ultimately, the choice between digital and offset printing depends on factors such as print volume, quality requirements, turnaround time, and budget.

Preparing the plastic
Firstly, select the appropriate plastic material for your project. The type of plastic will depend on the desired outcome and the specific requirements of your image transfer. Common plastics used for digital image imposition include polyesters, polyvinyl chloride (PVC), and recyclable polyester sheets. Ensure that the plastic is clean and free of any dirt, dust, or other contaminants that may interfere with the image transfer. Use a clean, damp cloth to wipe the plastic surface if necessary.
Next, determine the method of image transfer. Several techniques can be used, each with its own unique requirements. For example, the dye diffusion thermal transfer (D2T2) method involves using heat to promote the diffusion of dyes into the plastic substrate. This method is suitable for materials such as polyesters and PVC. Other methods include laser engraving, wax thermal transfer, and indirect D2T2 transfer, which uses a laser to burn a monochrome image onto the plastic. If you plan to use the D2T2 method, prepare the dye donor ribbon by coating one side with panels of the three dye formulations (yellow, magenta, and cyan) mixed in a solvent.
If you are using a pre-printed image transfer method, such as the one developed by ICI Imagedata, prepare the recyclable polyester sheet by coating it with polymer coatings receptive to ink-jet inks containing sublimable colourants. Use aqueous ink-jet technology to print your desired image onto the prepared sheet. Ensure that the image is printed in reverse if it needs to be viewed from the opposite side.
For a simple and direct image transfer method, you can use a photocopy or laserjet print of your image. Place the print, image side down, onto the clean plastic surface and secure it with masking tape. Apply a blender pen, filled with special fluid, to the back of the print, using even strokes to avoid soaking the paper. Burnish the image onto the plastic using the back of a heavy wooden spoon, moving in a tight, circular motion to cover the entire image thoroughly. Finally, remove the masking tape from one corner to check the quality of the image transfer. If necessary, repeat the blender marker and spoon burnishing process for a clearer image.
It is important to note that printing on plastic can be challenging due to its tendency to repel paint and resist carving tools. However, with the right materials and methods, you can successfully impose digital images onto plastic surfaces.
