Using modern, computer-aided screen printing machines, drinking glasses can be decorated in several colours in one printing process. The glass ceramic inks are fired at temperatures of 560 to 630oC.
Porcelain is fired at around 780oC in special decorating kilns. You can decide halftone and spot colours with reference to HKS or Pantone colour palettes.
A wide range of colours satisfies nearly every requirement. These colours offer high dishwasher and scratch resistance and so retain their brilliance over a long period.
Even direct printing is subject to limitations. If special requirements exist with regard to the decoration – for example, positioned very close to the handle, complex geometrical shapes, photo realistic images or the application of a decoration over an edge – glass ceramic decals must be used for decorating.
The motifs are applied to specially coated papers using screen or offset printing, and then individually applied to the item by hand by the water-slide decal method. The item is then fired at 560-820oC to make it dishwasher-safe.
Metallic colours in gold and silver are reasonably priced alternatives to decoration using precious metals. Compared with precious metals, metallic decoration also offers much better dishwasher resistance.
Transparent printing lends a unique quality to satinised glasses. Decorative elements can be rendered transparently on frosted glasses.
Special treatment of the glass surface can create a matt or frosted effect. A satin finish can generally only be applied to glass, and we can apply your decoration in addition.
Glass, porcelain or ceramic items can be coloured to suit your particular requirements. Transparent, matt or opaque colours are machine-sprayed onto the item.
Etched white decoration
Etched white decoration is a visual alternative to genuine engraving. Compared with engraving, etched white decoration offers a huge price advantage. It also ensures very good dishwasher and scratch resistance, even on glassware that can only be fired at very low temperatures due to its shape and glass mass.
Applying an effervescent point to the base of sparkling wine or champagne glasses causes the carbon dioxide dissolved in the drink to form into a bubble and to foam or effervesce as a result.
Precious metal printing
Precious metals such as gold, silver or platinum can be combined with other colours in a decoration or applied as a single colour. However, they are only dishwasher-proof to a limited extent.
