Does your realUV LED Floodlight properly expose a standard size silkscreen?
Could you tell me if your 20W 395nm UV-led flood light will properly expose a standard size 20"x24" silkscreen? If so, could you tell me what brand of emulsion is for solvent-based or plastisol-type inks? I can't find any info on your site that says it will work or won't work. Are the 395nm UV-led strips effective in the same application? Approximately how far apart should the strips be and approximately how far away from the screen?
Unfortunately, we do not have any test or reference data for silkscreen exposure applications. Several customers who have used our products have reported success using the 365 nm wavelength variant of our LED strip lights. The exact requirements are likely to depend on the emulsion product and variations among manufacturers and formulations. If you have any additional information on peak wavelength sensitivities or irradiance requirements, we may be able to provide some additional guidance here.
For your reference, below is an example of a customer who successfully used the 365 nm UV LED strips to produce a similar solution:
We do apologize that we do not have any readily available literature or data on silkscreen UV applications. As we enter the new year we do hope to be able to provide additional information for this specific application as we have seen quite a bit of interest in this area.
In the meantime, we would perhaps recommend testing and taking advantage of our free returns policy. If for whatever reason you find that the LED strips are not going to work for your project, we would be more than happy to pay for return shipping and offer a full refund. All we ask is for you to keep the LED strips in their original condition, meaning that the adhesive liner must not be removed and that the LED strips must not be cut into any shorter sections or otherwise altered.
