Small dictionary of glass and decorations
Gauge-mark - firm marking of nominal capacity on the glass,
i.e. capacity measure (usually by screen printing or sand blasted)
Acceptable tolerance of the measure is ± 2-4% of nominal
capacity, depending on the size of glass. Usually the signature of
decorator responsible for the proper marking is put under the measure
Ceramic decoration - in terms of IMS technology decoration,
it is an on-glaze decoration
Pressed decoration - company emblems, customer's advertisement
emblems put on the glass surface transferred directly from the mould
Optical inks - symmetric structure inside or outside of the
glass surface interfering with the transparency of walls
Organic paints - paints with definitely wider range of colours,
less abrasion resistant, fired in temperature below 200°C
Colours conflict - we use it mainly in reference to screen
printed decorations; under strong influence of aggression of some
colours, i.e. red, blue or yellow towards precious metals a chemical
reaction takes place, which blurs sharp colour contours or introduces
additional boarder colours
Decoration margin - distance between side line of glass outline
and the edge line of decoration - at least 1 cm; by exceeding
the distance, the decoration moves to the field of the so called wallpaper
decoration
Electronic material - decoration design on a floppy disk, CD-ROM
or sent by e-mail as a file in vectorial form (curves), enabling quick
preparation of films for production of decals patterns or for preparation
of screens. The following formats are accepted: Adobe Illustrator 8.0,
Adobe Photoshop 5.0, Macromedia Freehand 8.0 and Corel Draw 8.0
Frosting - usually, acid processing of glass for the result
of milky colour of the outer surface
Decoration distance - at least 20 mm from the rim, as
the safe distance between decoration and the surface of physical contact
of a consumer with a glass
Moussier point - intentional violation of bottom structure
with a diamond drill or laser for getting the effect of 'bubbles'
directly from the point in carbonated drinks (sparkling wine, beer)
Direct screen printing - transfer of paints to glass by a printing
machine with the use of earlier exposed screen and a squeegee adjusted
to it
Indirect screen printing - transfer of paints to glass with
the use of a transparent film called the decal
Mouth-blown glass - glass usually produced in smaller quantities,
much more expensive than the automatically formed glass, showing less
dimension stability, however, in some cases irreplaceable by automatic
production for economic or technological reasons
Own moulds - some companies undertake additional financial
effort and buy specially designed moulds in factories, to get the
exclusive right for the given kind of glass. Often, the purchase of
a mould is the condition of starting the production of a new model
of glassware
Abrasion resistance of decorations - resistance measured with
the maximal number of washing cycles in gastronomic dishwashers which
do not influence the quality of decoration. Because of low hardness,
precious metals fade in the first place. Paints fade during washing
quicker or slower, depending on the degree of their resistance and
the technology of firing used. It is possible to influence the durability
of each decoration (check the leaflet concerning care information
included in every packing with glass decorated by IMS Glass Decor)
Brim - (s-rand) glass rim is heated-up in higher temperature
than the rest of glass, which results in local melting of glass increasing
the glass impact resistance
Ice decoration - transparent relief decoration
Fully resistant decoration - decal or screen printing decoration
with fully resistant paints, i.e. the most resistant to abrasion,
fired in temperature 630°C. Because of the firing temperature,
it is suitable only for thick walls glasses
Wallpaper decoration - decoration covering at least 50% of
the surface of decorated glass, usually more expensive both for decals
and for screen printing
Gold rim - decoration of rim with gold of concentration 8-12%
