Firstly, it is important to clean the surface of the ABS plastic with alcohol and a lint-free cloth. This will ensure the removal of any dust, dirt, grease, or fingerprints that may compromise the quality of the print. Subsequently, dry the surface with a hairdryer or an air gun to prevent any moisture or condensation from interfering with the curing process.
Priming and Masking
The next step is to prime the surface of the ABS plastic with a primer spray. This step will enhance the adhesion and durability of the ink. You have the option of choosing between a clear or colored primer, depending on your desired outcome. After priming, mask the areas of the ABS plastic that you do not want to print on with masking tape. This will protect those areas from unwanted ink exposure.
Printer Settings and Loading
Now that the ABS plastic is prepared, you can proceed to choose the appropriate printer settings. Adjust the parameters such as ink type, resolution, speed, and temperature according to your specific requirements. Once the settings are finalized, load the ABS plastic into the printer tray or bed, ensuring that it is flat and secure. If needed, you can use clamps or magnets to hold it firmly in place.
Image Alignment and Preview
Before initiating the printing process, align your image with the ABS plastic using software or a manual guide to ensure correct positioning. Most printers also offer a preview function, allowing you to visualize how your image will appear on the ABS plastic before printing.
Final Preparations
At this point, you are almost ready to begin printing. Simply cure your ink with UV light, and you can proceed to print on the ABS plastic. The UV light will instantly cure the ink, eliminating the need for drying or coating.

Choosing the right printer settings
When selecting the appropriate printer settings, consider the following parameters:
- Ink Type: Choose an ink specifically formulated for ABS plastic, such as the Natron TP pad printing ink, which offers high opacity, excellent adhesion, and high gloss.
- Resolution: Determine the desired resolution or image quality for your print. ABS plastic is capable of producing sharp and well-defined prints due to its smooth surface.
- Speed: Adjust the printing speed according to your requirements. Keep in mind that slower speeds may be necessary to prevent melting or cracking of the ABS plastic.
- Temperature: ABS plastic requires careful temperature control. Printing at too high a temperature can result in a rough texture, while a slightly lower temperature may improve the print quality. Adjust the temperature incrementally to find the optimal setting for your specific printer and ABS material.
- Pressure: When using a pad printing machine, adjust the pressure to achieve the desired opacity. With high-quality ink, you may only need one pass to achieve the desired result.
It is recommended to perform a test print before finalizing your settings. This allows you to assess the quality and accuracy of the print and make any necessary adjustments to the printer settings. Additionally, ensure that the ABS plastic surface is properly prepared and clean before printing, as contaminants like dust, oil, or grease can affect ink adhesion.
