Decal APPLICATION
Instructions:
The design(s) are printed on a specially coated paper, a
carrier (cover-coat, which disappears during the
firing process) is printed over the design that allows the print to
slide off after wetting.
- For best results clean the ware to be
decorated before applying the Waterslide Decal
transfers.
The
decorating surface must be clean and free from any grease, dust or dirt
particles. This is to ensure proper firing and bonding between the decal
and the surface/substrate. Any dust, dirt or chemical on your
substrate will have an unwanted effect on the fired product.
- Carefully cut around the printed design
(if provided on a full sheet) OR each decal will slide off the paper
individually.
- Fully immerse the decal transfer
in a shallow pan of clean cool water and soak
for about 10 -15 seconds, so the paper is
completely wet. Remove from the water and wait for 60 - 90 seconds (or until the decal can
be released from the backing paper.)
Warm
water can be used for moulding the decal on irregular surfaces. The decal
should easily slide away from the paper -
avoid soaking the
decal too long, otherwise it may release itself from the backing paper and
float in the water, making it difficult to handle.
The soak water should be changed
frequently to reduce impurities and water soluble gum that builds up in
the water.
- The decal can now be applied to the
ware (as printed, face up) in a couple ways.
Method #1:
(For Very Large Decals) Apply decal over the object face-up, and slip out
the backing paper from underneath. Adjust the positioning of the decal on the
ware/substrate and remove water using a rubber squeegee.
(We recommend using a squeegee with a medium flex.) This is
accomplished by patting down from the center toward the outer edges until
all excess water has been removed and wrinkles and air bubbles have been
smoothed out.
Finish by wiping the
top of the decal with a damp lint-free cloth(or paper towel) to remove any residual
water. This is a very important step because water
can leak back down under the decal. Using an external heat source, (ie a
heater) can help with a quick dry time, and less chance of water sneaking
back under the decal. When properly applied, a decal will not
slide around on the ware; check thoroughly for air or water bubbles to avoid
blowouts during firing. Using an external heat source, (ie a heater) can
help with a quick dry time
Method #2:
Remove 10 to 12 decal sheets from the pan and place them face-up on a coupe
plate or shallow dish. Slide decals off the paper with a finger (do not
“pick”) and apply each individually to the ware. Straighten the decal and
remove water as described in Method #1.
When all of the decals
from the top sheet have been removed from the backing paper, discard the
backing paper and begin using the decals from the next sheet.
- Allow decorated pieces to dry
thoroughly.
Allow to dry for
at least 2 hours in a warm area
or overnight before firing to allow all moisture to evaporate as
any moisture left behind will cause blowouts in the design during firing.
- The transfer is now ready for firing.
Allow sufficient spacing between your wares, to allow heat to circulate.
FIRING Temperature:
Lower firing is for glassware applications. 560 - 620º C (1040 - 1120ºF) or Cone 022 / 021
Holding peak temperature 10 – 20 minutes (longer depending on conditions and
equipment)
Higher firing is for ceramic/porcelain
applications. 735 - 770ºC (1360 - 1420ºF) or Cone 017.
Holding peak temperature 10 – 20 minutes (longer depending on conditions and
equipment)
For best results, allow decorated ware to
thoroughly dry before firing. These temperatures are by no means absolutes
and we therefore suggest that you
request samples to try on your wares under
your conditions. Firing conditions and substrates
will vary and will have varying results.
Under optimum conditions, the firing cycle
should be slow and well ventilated.
Please note that we cannot take
responsibility for the lead and cadmium levels of the ceramic/glass decals
when fired. Unless otherwise stated please DO NOT
decorate on surfaces that come in contact with food or drink.
Please see
our regulations
page. We also will be stocking Lead-Free colors in the near future.
If decals are used on food-bearing surfaces,
we strongly suggest that the products be tested to comply with FDA
and state rules.
STORAGE of Decals:
One of the greatest problems in the storage of decals is sticking of the wax
paper to the decal.
We recommend storage of the decals in
air-conditioned rooms (humidity 55-65% moisture) and on the decal paper's
EDGE. Decals should
be stored at a constant room temperature of approximately 68-74ºF. With
proper storage, the decals have a shelf life of 1 - 2 years. Some colors may
be effected over a longer period of storage.
