I have to admit, I'm not likely to invest in the Optimist inks. However, I have been curious about them so I appreciate you sharing what you're doing. I do have some really pretty Sennelier shellac inks. That isolation layer is giving me all kinds of ideas for other things to try as well.
Wonderful video. As a gel printer I appreciate your tips for using these inks. I’m still on the fence about purchasing these. I wondered could you use a gloss medium instead of the matte medium?
