Most nail art printers on the market today target the professional beauty market (specifically salons and retailers) and require nail tech involvement for the best wear. “Nailae’s nail designs look even more amazing if the client has started with a good manicure,” Nailae’s website explains. These brands encourage nail professionals to be the ones to prep the nail, apply the solid polish coat, apply the primer, position fingers appropriately in the machine, optionally add embellishments to the printed design, and apply top coat after. They are not intended to be self-service. With the nail tech expert on hand, these printers may avoid some of the user-error pitfalls that plagued Mattel’s printer.
