What You'll Learn
Preparing the plastic surface
Firstly, it is important to clean the surface of the ABS plastic thoroughly. Using alcohol and a lint-free cloth, wipe down the plastic to remove any dust, dirt, grease, or fingerprints that may hinder the print quality. This step ensures that the ink adheres evenly and effectively to the plastic surface.
Once the surface is clean, proceed to dry it completely. Use a hairdryer or an air gun to eliminate any moisture or condensation. This step is crucial, as any remaining moisture can interfere with the curing process of the ink.
Next, apply a primer spray to the surface of the ABS plastic. This step is essential to enhance the adhesion and durability of the ink. You can choose between a clear or coloured primer, depending on your desired outcome. The primer will also help create a consistent base for the ink to adhere to.
After priming, carefully mask off any areas of the ABS plastic that you do not want to be printed on. Use masking tape to cover these sections, ensuring that only the desired printing areas are exposed. This step protects the rest of the plastic surface from unwanted ink exposure.
Additionally, if your ABS plastic has any unique features, such as buttons or holes, carefully consider how you will work around them. Depending on the complexity of the shape, you might need to create a custom jig or screen jig that allows you to print effectively on the desired surface area.
Finally, it is recommended to perform a test print on a similar plastic surface or a scrap piece of ABS plastic before proceeding with your final print run. This will allow you to adjust any necessary settings, such as ink type, resolution, speed, temperature, squeegee angle and pressure, to ensure optimal results on the actual ABS plastic surface.

Choosing the right ink
ABS plastic has a smooth and glossy surface, which is well-suited for screen printing. The ink should be able to adhere well to the ABS surface, without easily smudging or running, resulting in sharp and well-defined prints. Inks with good adhesion properties, such as those specifically designed for pad printing on ABS, are ideal.
Additionally, the ink should have suitable viscosity for screen printing. The ink should be fluid enough to pass through the mesh screen but not too thin, as it may lead to excess ink transfer and affect the quality of the print. The exposure time and mesh count also play a role in ink selection, as they have an inverse relationship. As one increases, the other decreases, impacting the ink transfer and curing process.
When printing on ABS plastic, it is also important to consider the preparation of the surface. Cleaning the surface with alcohol and a lint-free cloth ensures the removal of any contaminants that may affect ink adhesion. Drying and priming the surface further enhance the adhesion and durability of the ink.
For screen printing on ABS plastic, a few specific ink types can be considered. Vinyflex solvent ink, a multipurpose ink compatible with Pantone®, is commonly used. Other options include Cellulosique STJ, Plastic Fluo, Plaxolor, Selectacryl, Urethal, Glossy Vinyl, and Mat Vinyl. Each of these inks has unique characteristics and properties that should be evaluated based on specific requirements and compatibility with ABS plastic.

Printing methods
Printing on ABS plastic requires a different approach from printing on materials like cloth or paper. This is because the plastic surface does not have the porosity to absorb ink like paper. Therefore, the surface of the plastic must be processed before printing to improve ink adhesion.
The most common printing methods for ABS plastic are pad printing, screen printing, and UV printing.
Pad Printing
Pad printing is a popular choice for printing on ABS plastic due to its smooth and glossy surface, which allows for consistent ink adhesion and transfer, resulting in high-quality prints. ABS also offers good adhesion properties for inks used in pad printing, and its durability ensures that the printed images or markings won't easily wear off or become damaged.
Screen Printing
Screen printing is another option for printing on ABS plastic. This method involves transferring an image or information onto a plastic product using a printing screen. The screen printing screen, squeegee, ink, printing plate, and substrate are the five major elements of screen printing. The ink is poured at one end of the screen, and the squeegee is used to press and slip the ink to the other end, transferring it through the screen mesh onto the plastic substrate. The exposure timing, squeegee angle, pressure, and hardness may vary depending on the desired outcome.
UV Printing
UV printing is a versatile method that can produce high-quality images with vivid colours and sharp details on ABS plastic. Before UV printing, the ABS plastic surface must be cleaned, dried, primed, and masked to ensure proper preparation. The printer settings can then be adjusted, and the ABS plastic is loaded into the printer tray or bed. The image is aligned with the plastic, and the ink is cured with UV light during the printing process.

Curing the ink
Before curing the ink, it is important to prepare the ABS plastic surface. This includes cleaning the surface with alcohol and a lint-free cloth to remove any dust, dirt, grease, or fingerprints that may affect the quality of the print. The surface should then be dried with a hairdryer or an air gun to remove any moisture or condensation that may interfere with the curing process.
Once the surface is prepared, the ink can be cured using UV light. UV printing technology uses ultraviolet light to cure ink on various surfaces, including ABS plastic. The UV light will instantly cure the ink, and no additional drying or coating is needed. This method produces high-quality images with vivid colours and sharp details, and it can also resist fading, scratching, water, and chemicals.
Another option for curing the ink is to use a curing oven. The printed part can be placed in the oven to cure, or it can be left overnight to air dry and cure. At room temperature, the ink will cure in 3 days.
It is worth noting that the choice of ink is also important for the curing process. Pad printing inks, such as the TP series, are specifically designed for ABS plastic and provide high-quality pigmentation, allowing for precise and accurate transfers of the design with minimal ink waste.
