No there not pre dispersed, pre dispersed are pigment pastes which are very finely ground to very small micron sizes often around 1.5 - 2 micron or even smaller nano microns such as printer inks these are the colours which travel under the skin like the blacks that cant be used for lining, these pastes are usually industrial grade dispersions containing industrial grade surfactants or resins and preservatives then thinned down with water and alcohol and sold as tattoo inks the problem with these are the manufactures wont disclose the actual ingredients so you really dont have a clue what your putting in the skin. Our colours are dry pigments mixed with pharma / food or cosmetic grade ingredients then dispersed through a small bead mill to a larger micron size around 5 micron and supplied ready to use, hope this helps.
