What Is This UV Machine For Photopolymer
This UV nail-type machine works as a compact exposure unit for curing photopolymer plates, mainly used in stamp making, like Toyobo BF95.
It emits ultraviolet light at 365 nm, a wavelength particularly suitable for the controlled hardening of solid photopolymers. This type of lamp is commonly used as a cost-effective and efficient alternative to industrial exposure units when working with small and medium formats.

UV Curing For Photopolymer Stamps
The curing process depends on the type of photopolymer and the positives used. As a general guideline, exposure times typically range between 5 and 8 minutes.
This machine allows the process to be repeated consistently, which is especially important in educational environments, craft workshops or small-scale production.
To fully understand the complete stamp-making process, recommended exposure times and correct use of photopolymer, it is advisable to consult the technical tutorial available on the Rittagraf blog about making photopolymer stamps using UV nail-type machines.
This resource expands on the information provided in this product page and helps optimize results, particularly in educational or beginner contexts.
Recommended Use And Limitations
This compact exposure unit is specifically designed for curing photopolymer used in stamp making.
It is not intended for exposing screen-printing screens or for work requiring large exposure areas. In such cases, higher-power UV LED lamps or dedicated exposure systems for screen printing are recommended.
Compatibility With Stamp-Making Kits
This UV machine is used as the exposure system within the Rittagraf photopolymer stamp-making kit, a complete solution that includes the materials and tools required to carry out the entire process from start to finish.
It is particularly suitable for users looking for a practical, compact and reliable solution for working with photopolymer without the need for industrial equipment.
FAQs About The UV Machine For Making Photopolymer Stamps
Can I use a UV nail machine to make photopolymer stamps?
Yes. This type of UV machine emits light at 365 nm, which is suitable for curing photopolymer plates used in stamp making.
How do I use this UV machine and what exposure times are required?
Using this UV machine is straightforward, but exposure times may vary depending on the type of photopolymer, the opacity of the photomask and the glass used. As a general guideline, exposure time is usually around 8 minutes.
For a detailed step-by-step explanation, it is recommended to consult the technical tutorial on making photopolymer stamps with UV nail-type machines on the Rittagraf blog.
What is the maximum stamp size that can be made?
Approximately up to 8 × 8 cm.
Is it suitable for screen printing?
This machine is intended for photopolymer and stamp making, not for exposing screen-printing screens. Although it is not the most recommended application due to size and wavelength, it could be used with careful testing of exposure times.
Does it include a timer?
Yes, it includes a 120-second timer or a direct on/off switch, depending on the version.
