REEL CREATIONS™ Blue Screen and Green Screen Inks are specially designed for use on the skin to accommodate the Blue Screen or Green Screen digital post process. This Green Screen Ink is in the same basic formula as all the REEL Body Art Inks except that it is specifically formulated to work with and match the Blue Screen color processing. It is essential that the base coat of REEL White #8, included in the kit, be applied to skin before applying the Green Screen ink. This process will bring out the true chroma of the blue color when applied over the white, so the blue is an exact color for post production use. This product is best applied with an airbrush so you get a clean and smooth application, especially for large areas that need coverage. It can be applied by hand with a brush, but you must be extremely careful when applying one layer over the other so that they don't dissolve down. Allow layers to dry thoroughly, and seal the white layer first with Blue Aqua Sealer, before applying the Green Screen ink. Be careful not to over-saturate with Blue Aqua Sealer when applying, or you will dissolve down the layers. FOR PROFESSIONAL USE ONLY.
