Printing on glass surfaces can be a challenge due to their unique characteristics
Printing on glass surfaces can be a challenge due to their unique characteristics, including their smooth and non-porous surface . However, pad printing is an excellent method for achieving high-quality prints on glass surfaces. This method is highly effective in transferring ink to irregular or curved glass surfaces, making it a versatile solution for printing on various glass items.
To ensure successful pad printing on glass, it is crucial to use the right ink type and ensure proper adhesion. Farbaglass inks are the most commonly used inks for printing on glass surfaces as they are highly durable, scratch-resistant, and can withstand high temperatures without fading or smudging. Additionally, it's essential to clean the glass surface and remove any debris or oils that could interfere with ink adhesion. Pre-treating the glass with a specialized primer can also improve adhesion and ensure long-lasting prints. Sometimes post treatment with UV is also recommended when printing on glass. UV treatment helps to harden the ink, making it more resistant to scratching, fading, and other forms of wear and tear. It also enhances the overall appearance of the print.
The glass industry offers a range of printing methods, including pad printing, screen printing, spray coating, hot stamping, and foiling. EPIC pad printing machines, provided by Spinks World, are an excellent choice for achieving high-quality prints on various types of glass, including flat, round, patterned, toughened, and tinted glass.

Ques 6 : Can you name some key Farbatech ink series for glass printing and their benefits?
Answer:
- FarbaUV (Screen Printing): A UV-LED-curable, 2-component ink known for excellent resistance, strong initial adhesion, and sustainable UV-LED curing benefits.
- Farbaglass PT (Screen & Pad Printing): A 1-component, solvent-based ink with high demands on adhesion and chemical resistance for both glass and PTFE.
- Farbaglass (Pad & Screen Printing): A solvent-based, glossy 2-component ink, easy to use on various substrates with high chemical, mechanical, and dishwasher resistance.
- Farbajet GLM (Digital Printing): A UV-inkjet ink optimized for industrial single-pass printing on packaging and hollow containers, offering speed and efficiency.
- Farbatech APT 204 (Liquid Coating): A 2-component, UV-curable liquid coating with excellent adhesion and very high chemical and mechanical resistance on glass.
Ques 7 : Are there UV-curable or LED-curable inks available for glass printing?
Answer: Digital printing on glass with inks like Farbatech’s Farbajet series allows for direct printing on packaging and hollow containers. Its advantages include: Absolutely. Farbatech offers advanced UV-curable and UV-LED-curable inks for glass, such as FarbaUV and Farbatube. These inks provide excellent resistance and adhesion while offering energy, time, and space savings due to rapid curing.
Ques 8 : What is the purpose of a primer or liquid coating in glass printing?
Answer: A primer (like IJM/M1) is a liquid adhesion promoter used for pre-treating glass materials. It significantly improves the bond between the glass surface and the ink layer. Liquid coatings (like APT 204) are applied as a protective layer, offering very high chemical and mechanical resistance to the printed surface.
