* Bolder designs are recommended in order to prevent any unsatisfactory coloring caused by lines and figures that are too thin or too small and will require an additional silk-screen printing process.
* General enamel coloring requires a surrounding metal space to ensure good quality painting results. Therefore it is usually necessary to allow for a blank metal rim (0.3mm minimum). If you require full-piece coloring, a special printing process is necessary.
* The standard colors are based on the AOKI Cloisonne colour chart. For those who prefer Pantone colors, synthetic/ imitation enamel can be used instead. However, this is not as hard as real Hard Enamel but more shiny and clear in color.
