Best UV Blocking Black Ink for Film Positives on Canon Pixma iX6820

Question:
I’m looking for UV-blocking black ink that can be used for printing film positives with a Canon Pixma iX6820. Can you recommend one of your products that would work well for this application?

Recommended Ink for Canon Pixma iX6820

For Canon printers, the best option we offer is our Premium 500 ml Black Dye Ink for Canon. You can find it here: Premium 500 ml Black Dye Ink for Canon (https://bchtechnologies.com/products/premium-500-ml-black-dye-ink-for-canon-id500k-ac?_pos=6&_sid=1b4a43542&_ss=r).

This is a dye-based ink, which is critical for film positives. Unlike pigment ink, which can sometimes scatter unevenly on transparency film, dye ink spreads and forms a smooth, even layer. That even coverage creates better density and results in stronger UV blocking, which is essential for high-quality screen printing or other film positive applications.

What If You Have an Epson Printer?

If you also use or have access to an Epson printer, an even better choice for UV blocking performance would be our Premium DTF Black Ink. You can see it here: Premium DTF Direct to Film Ink – 100 ml Black (https://bchtechnologies.com/products/premium-dtf-direct-to-film-ink-100-ml-black?_pos=1&_sid=5b7a4f72e&_ss=r).

This ink has the highest density and UV-blocking capability among the inks we carry. However, it is only compatible with Epson’s printhead technology and cannot be effectively used in Canon printers.

Why UV Blocking Matters

For film positives, UV blocking is crucial because it ensures that light does not pass through unintended areas during exposure. If the black ink isn’t dense enough, light leaks through the film, leading to weak stencils, blurred lines, or failed transfers. Choosing the correct ink type makes a significant difference in producing sharp, accurate results.

Addressing printer needs and troubleshooting can be a complicated affair because every setup and application can be slightly different. That’s why we don’t provide remote support or one-on-one troubleshooting for specific ink setups. However, we do offer in-person evaluations through our printer repair and service center (https://bchtechnologies.com/printer-repair-service). Demand for this service is high, so it operates on a first-come, first-served basis, and wait times can be several weeks. While our repair pricing may not be the most economical, we strongly encourage self-help options through online resources. A great place to begin is our YouTube channel (https://youtube.com/@bchtechnologies), where you can use the search icon on the channel’s homepage to locate videos specific to your needs. With over nine years of content, the search tool is the fastest way to find answers, and YouTube may also suggest helpful videos from other creators.

Thank you again for your question and for trusting BCH Technologies as a resource for your printing projects. We look forward to continuing to support the printing community with both supplies and knowledge.
