Can the black dye used on Elastic 50A resin?

I am using Elastic 50A resin in a FL3+; the resultant print is a clear.
Instead I want the print to be black/

Can I use the Formlabs BLACK in the color kit with Elastic Resin?
How much do I use??

Hi @alan1950,

The color kit pigments contain photoinitiators, which can result in suboptimal print results when used with resins other than Color Base. Instead, to dye Elastic 50A, you can use alcohol ink as described in our Guide to Dyeing, Painting, and Coloring SLA Parts. Dyeing the liquid resin may cause your print results to vary (especially dyeing black), but otherwise dyeing the parts after they are printed could be a good fallback option.
