Mediums specially formulated for dyes) used on the crstal glass mosaic surface are ideal for screen printing, roller printing and spray methods. These mediums developed by FARPER CHEMICALS are divided into two sections as green solvent (oil) and water based; used with diluents adjusted depending on the type of the product. They are applied to the glass surface along with dyes in compliance with the printing method which possess the feature of drying rapidly. Medium series through its effective formula; viscosity and density of the dye remain stable all throughout the production. Perfect color transfer is accomplished onto the glass while colors and tones achieved during the production remain stable. No sedimentation is observed in the dye even during long storage periods.
