Method for electrostatographically producing master images for decoration of ceramic objects

An electrostatographic method for producing a master image for decorating ceramic, enamel or glass objects comprising the steps of:

• providing a temporary support having a surface with release properties,
• image-wise depositing at least two layers of charged toner particles, having a volume average particle size d.sub.v50t, such that 5 .mu.m<d.sub.v50t <15 .mu.m and including particles of a ceramic pigment, CP, having a volumetric particle size distribution such that 90% of said particles have a diameter lower than 2/3 times d.sub.v50t and
• providing particles of glazing material between said at least two layers of charged toner particles, said glazing material having a volumetric particle size distribution such that 90% of the particles have a diameter lower than d.sub.v50t, in said master image.
