In a major and significant new development, a patented and reportedly unique photopolymer capillary film has been produced for close tolerance work and critical thin and thick film applications. The film results in stencils with exceptional resistance to both water based UV and solvent based inks. Designed and manufactured by Murakami, available from Coates Screen, and known as MS-WR, it was specifically produced for enhanced performance with water thinnable, water based, conventional UV and solvent based inks (Plate 6).

MS-WR is particularly suitable for UV 4-colour process printing, where the 15 micron grade is ideal for the very much finer meshes used.

Particular features of Murakami MS-WR film are its shorter exposure times than needed with diazo types, its superior definition and resolution, its flexibility and adhesion to polyester and stainless steel meshes, and its excellent durability.

Coates Screen is adding this new product to its range of UV and process printing products at a time when many see conventional technologies as reaching their limits and industrial applications are setting still higher requirements. The company quotes Murakami's chemists, who indicate the potential of SBQ technology for widening the performance of screen printing.
