The idea of converting the Epson L1800 printer to use UV ink is gaining traction, as users seek to expand the capabilities of their machines. A recent conversation sparked curiosity about the possibility of curing UV ink after the paper is fully printed, rather than instantly during the printing process. This article explores this query and addresses concerns related to potential issues such as ink spreading and unintended curing.
UV Ink Curing: Post-Printing Possibilities
The initial question revolves around the feasibility of curing UV ink after the paper is fully printed, as opposed to the conventional method of curing during the printing process. This approach presents a unique perspective that could have practical applications, especially when dealing with various substrates.
Ink Spreading Concerns: One user raised concerns about ink spreading, particularly when printing on plastic. The fear is that if the curing process is delayed until after the paper is fully printed, the ink may spread, resulting in a compromised print quality. This concern is valid, as UV ink typically requires immediate curing to prevent unwanted spreading and distortion on certain materials.
UV Lamp Setup: Addressing Compatibility and Substrate Challenges
Another user expressed admiration for a UV ink setup and sought information about the specific UV lamp being used. This user plans to print on Oracal or 3M vinyl, materials known for their diverse applications. The user highlighted their success with dye and pigment inks on uncoated media and questioned whether UV ink would exhibit similar behavior.
UV Lamp Selection: The choice of a UV lamp is crucial for successful UV ink curing. While the specific UV lamp model used in the admired setup is not disclosed, it is essential to select a lamp that suits the printing requirements. The concerns raised about water-cooled lamps suggest a need for efficient cooling solutions, especially when dealing with extended printing sessions.
Compatibility with Uncoated Media: The user's past experience with dye and pigment inks on uncoated media raises questions about UV ink's behavior on similar substrates. While dye and pigment inks may not bond well with uncoated media, UV ink characteristics may differ. Understanding the unique bonding properties of UV ink is essential for achieving optimal results on specific substrates.
Addressing Concerns: UV Light Exposure Risks
The conversation also touched on concerns about the unintended curing of components outside the printing area. The user worried about UV light from the lamp potentially curing the wiper, capping station, and, worst of all, the printhead over time.
Mitigating UV Exposure Risks: To address these concerns, careful consideration must be given to the placement and direction of the UV lamp. Shielding sensitive components from direct UV exposure is crucial to prevent unintended curing. Additionally, exploring UV-blocking materials or coatings for vulnerable components can provide an added layer of protection.
Further Exploration
The prospect of converting the Epson L1800 to UV ink and exploring alternative curing methods opens up new possibilities for users seeking versatility in their printing capabilities. While challenges such as ink spreading and unintended curing risks need careful consideration, a well-thought-out UV ink setup, coupled with strategic precautions, can lead to successful outcomes.
