Method for preparing flexographic matrixes for printing cylinders, typically for decorating ceramic tiles, disposable flexographic matrixes obtained thereby and modular printing cylinders equipped therewith
A method for preparing flexographic printing matrixes, characterised by the following operative stages: providing a form comprising a thin-walled rigid cylindrical sleeve provided with two outer circumferential end shoulders, and locking it in an upright position at an injection station; creating about said sleeve a first annular forming chamber extending between said shoulders; filling said first chamber with a first fluid elastomeric material which on termination of curing is soft and elastically deformable; creating about said first material, when cured, a second annular forming chamber narrower than the preceding; filing said second chamber with a second fluid elastomeric material which on termination of curing is flexible and non-deformable; and removing the piece formed in this manner from said station when said second material is
