CUSTOM DECALS
Decal Specialists has
invested in state of the art digital printing technology, enabling the
production of Custom Ceramic Decals from original artwork, with a minimum
order of one A3 sheet. If only one sheet is ordered, it may consist of
multiple units of one piece of artwork or a number of different pieces
of artwork. It’s possible to mix and match
and literally ‘fill up’ each A3 sheet.
ARTWORK DELIVERY
Original digital artwork can be efficiently uploaded to the Decal Specialists
website. An artwork upload ‘link’ is located on the Home
Page. All technical specifications are noted on this link, but in simple
terms, image resolution of 600dpi is recommended (300dpi minimum) and ‘tiff’ files
are preferred.
If digital artwork does not exist, Decal Specialists can arrange for
artwork to be scanned or created.
Custom Decals can be produced from original photography, illustrations
and typography.
DECAL STORAGE
Custom Decals are supplied with an interleaving sheet between each decal
sheet to ensure that the decals do not stick together. It is recommended
that the decal sheets be stored on edge and that interleaving sheets
are removed only when the decals are to be used. Ideal storage conditions
are 15 to 18°C in a relatively dry environment.
DECAL APPLICATION
Custom Ceramic Decals are usually applied on fired, glazed finishes.
Most of these surfaces are white, ivory or pastel.
It is most important that application and firing instructions (supplied
by Decal Specialists with every Custom Decal order) are followed to the
letter and if possible, proper application equipment is used.
Custom Ceramic Decals should be applied to a ceramic piece as follows:
1. Cut the motif (decal) from the A3 sheet.
2. Place the decal in a container of lukewarm water until the paper curls.
3. Remove the decal from the water and leave for approximately 20-30
seconds until the decal slides free from the backing paper (this method
prevents the adhesive from dissolving away in the water and minimises
water take- up into the decal). Adding a drop of washing up liquid to
the water can help reduce surface tension and may also assist in making
bubbles easier to remove.
4. Ensure your ceramic piece is not cold and that the area to be decorated
is wet.
5. Slide the decal from the backing paper, face- up onto the wet finished
ware, and proceed to squeeze out all the water making sure no moisture
or bubbles remain underneath. Take extra care over dark areas as water
is
harder to remove. The decal should be held
in place with the finger of one hand whilst water and air are removed from
beneath the decal with
firm, deliberate strokes of a squeegee
(if possible). Move outwards from the centre of the motif.
Please note: incorrect or poor application may produce poor fired results.
Decal application tools, such as a rubber squeegee and lint-free absorbent
cloth, are recommended.
DECAL APPLICATION TOOLS
Although it is not essential to use special equipment to apply decals,
optimum speed, quality and efficiency can be achieved by using application
aids such as:
1. Rubber squeegee – a range is available to suit different applications
2. Rubber roller – for large areas or all-over motifs
3. Lint-free absorbent cloth.
TIME TO DRY
Wait at least 24 hours for the decal(s) to dry. Colder climates or higher
humidity obviously increase drying time. The acid test for dryness
is to set a small kiln at 200°C and insert a decorated piece for
5-10 minutes. If wet, the decal shows water blisters and if dry, it
stays flat and appears shinier.
BEST TO TEST
If multiple ceramic pieces are to be decorated, it is strongly recommended
that decal(s) be applied to one piece and fired to ascertain whether
any kiln temperature ‘tweaking’ may be required.
Optimum firing cycles depend on factors such as the type of kiln, the
shape and thickness of the ware and the comparative size of the load.
This is normally determined by experience. It’s best to test.
FIRING
Kilns may be electric or gas-fired. Venting to allow free access of air
for complete burn off of the organic materials in the decal is recommended.
Avoid draughts that could cause excessive temperature variations.
Fire slowly up to 200°C to allow any remaining moisture to evaporate,
and then up to 790-820°C. The recommended firing cycle is as follows:
1. 0 to 450°C in 180 minutes
2. 450 to 600°C in 30 minutes
3. Hold 15 minutes
4. 600 to 790-820°C in 30 minutes
5. Hold 15 minutes
6. Turn off.
