Ceramic Printed Glass



What is Ceramic Printed Glass?
Ceramic Printed glass also called Silk Screened glass has gained wide-spread for decoration and masking on building interior and exterior facades. Ceramic printing on glass is done with special enamels which are applied to glass before it is tempered. During the heating process in tempering or bending, this enamel fuses into the glass and becomes a monolithic construction.
This is as permanent as any printed ceramic like crockery at your home and all technical characteristics are same as that of unprinted glass. It is life long and does not deteriorate with weather, detergents, normal acids or alkali. The methods of applying these enamels before tempering are roller coating, screen printing, spray printing & direct on glass digital printing

Screen printed Glass:
Roller Coated Printed Glass:
Patterned Glass is a decorative and translucent glass with figuresroller coated glass
or patterns on one or both surfaces of glass. In addition to
diffusing light and obstructing visibility from the outside, the
figures soften the interior lighting. It is manufactured by a
method similar to float glass wherein the molten glass is passed
through rollers instead of floating on a molten tin bath. These metallic rollers are engraved with some patterns
or designs, which are cast into the formed glass and can be used
in most applications for lighting but no see through. This type
of glass is usually more brittle or fragile and less convenient to
clean.

Digitally Printed Glass:

Ceramic printing on glass is done with special enamels which are applied to ceramic 1
glass before it is tempered. During the heating process in tempering or
bending, this enamel fuses into the glass and becomes a monolithic
construction. It is thus, a permanent printing or coating and has all technical
/ mechanical characteristics of the unprinted glass. It is life long and does not
deteriorate with weather, detergents, normal acids or alkalis. The enamels
used are made of glass frit but the printed process is borrowed from printing
on ceramics, like bathroom tiles and crockery used at home.
The common methods of applying the enamel are :
1. Roller Coating : is best for printing solid colors and for applying only one
color.
2. Screen printing with ceramic frit: Is suitable for solid colors and normal ceramic 2
patterns like dots, squares, checks or lines in single color with repetitive
designs.

3. Direct on glass Ceramic Digital Printing: It is better suited when theceramic 3
printing design varies or changes from glass to glass and the final effect
required is one large image achieved by tiling of various glasses to make one
continuous image.
Certain areas of application make it important to mask a part or whole of glass for
privacy or hiding the background or enhancing the look of a product or for purely
aesthetical reasons. Silk screening was initially used in automobile windscreens
and backlite borders to hide the silicone smudges. It was then used in domestic
appliances. Lately it has been used in buildings, in curtainwalls, point fixed or
bolted glazing systems, shower installations, glass doors and partitions. The size, density and colour would
determine the opacity and shading, whereas the variety of dots, squares, checks and patterns will give many
design combinations to achieve the desired effect. There are however limitations on color choices, designs and
sizes, which may be confirmed before designing.
Ceramic printed or fritted glass is very safe and durable for architectural use for external and internal glazing
but is essentially a tempered glass, which has to be ordered to specific size and shape. Since it is processed at very
high temperature of about 7000C, there is a limitation on colors and brightness and is
not same as normal paints but is economic and technically sound option.
