Colour Wheel





Colour Wheel and Complimentary Colours


  • "red and green
  • blue and orange
  • yellow and violet
The complement of each primary color (red, blue, or yellow) is roughly the color made by mixing the other two in a subtractive system:
  • red complements (blue + yellow) = green
  • blue complements (red + yellow) = orange
  • yellow complements (red + blue) = violet
When two complements of opaque paint are mixed, they approximate black. For example, a little bit ofultramarine mixed with orange, produces a dark variation of black. Placed side by side as tiny dots, in partitive color mixing, they produce gray. As colored light projected on a white screen, in additive color mixing, they produce white.
The use of complementary colors is an important aspect of aesthetically pleasing art and graphic design. This also extends to other fields such as contrasting colors in logos and retail display. When placed next to each other, complements make each other appear brighter. On an artistic color wheel, complementary colors are placed opposite one another. "

Lazertran and Fabrics


Lazertran and fabric

LAZERTRAN IRONED ONTO FABRIC.
1. Copy your image in reverse then place the Lazertran face down on the cloth.
2. Set iron to hot and iron onto the cloth until it is well stuck.
3. Wet the backing paper and peel off. Wipe away gum from image and allow to dry.
4. Place baking parchment, not greaseproof paper, over image and iron. Allow to cool then peel off baking parchment and repeat until the image sinks into the cloth.
This method can be used for needlepoint canvas and tapestry canvas as a guide.

LAZERTRAN SILK

Have your own design, image from a book or even patterns from magazines copied, in reverse onto Lazertran paper. Then follow the instructions below.

Instructions for use.
1. Iron silk flat.
2. Set iron hot enough for the toners to stick to the silk.
3. Lay silk over your image and iron until the silk is stuck to the image.
4. Place the silk in clean warm water, paper down and leave until the paper falls off.
5. Lift the silk carefully from the water, lay the image face down and lightly iron with a cool iron till dry.
6. When dry, place a sheet of silicon baking parchment over the image.
7. Iron through the baking parchment then allow to cool. Peel off.
This method produces a beautiful result and can be rinsed in warm water but will not take a vigorous wash. Always iron with low setting through silicon baking parchment.

LAZERTRAN SILK NEW METHOD

Lazertran Silk can now be used to put images onto almost any surface using 3M Photo Mount Spray. Just copy your image onto lazertran Silk in reverse or mirror, cut to size and then spray an even coat of Photo mount onto the image. Press onto the surface and make sure it is well stuck. Iron with a medium heat iron if using on cloth. Wet backing paper, allow to soak for about one minute and slide off.
This method can be used on Voile, plastics, wood and in decoupage to put images down without thickness. It is also very good for interior decoration on walls etc.

FOR THICKER FABRICS LAZERTRAN CAN BE IRONED ON

This method can be used for cotton, needlepoint canvas and tapestry canvas as a guide.

1.Place Lazertran face down on the cloth.
2. Set iron to wool/cotton and iron onto the cloth until it is well stuck.
3. Wet the backing paper and peel off. Wipe off gum and allow to dry, or place, paper side down in a tray of water and allow the paper to fall off. Wash off any gum.
5. Place face down and iron lightly from the back until dry, lifting when cool each time to avoid the image sticking to your ironing surface.
4. Turn over and place silicon baking parchment over image and give it a good ironing. Allow to cool, peel off silicon sheet and repeat till the image sinks into the cloth.

Lazertran - difficult surfaces, curve, etch resist, metal foil.


PURE TURPENTINE METHOD.
TO FIX LAZERTRAN TO PAPER, WOOD, WAX, STONE, PLASTER, PVC, AND DIFFICULT SURFACES WITHOUT ACRYLIC.


1. Trim your image to size and lower, wide edge first, into clean water. Allow to soak for a minute or so.
2. Lift the Lazertran out of the water and make sure you have wiped away any excess moisture.
3. Soak your receiving surface with pure turpentine and slide the transfer onto the surface.
4. For paper, carefully roll flat with a soft roller moistened with pure turpentine and leave overnight. The transfer will melt and migrate into the surface. Do not over work the transfer, as it will smudge. Any bubbles will disappear overnight.
5. For surfaces other than paper, for instance rough wood, the melting of the image into nooks and crannies can be helped by brushing the image with pure turpentine. Do not force into holes or curves, as it will do this itself overnight.
6. For putting over existing oil paint, wipe the painting or brush over with pure turpentine. Then lay transfer onto the surface. If too much turpentine is used the image will break up. Always lay flat until dry. n.b. Turps substitute or white spirit will not work.

TO TRANSFER A STAMPED IMAGE ONTO A DIFFICULT SURFACE OR CURVE USING LAZERTRAN

Stamp your image directly onto a sheet of Lazertran using waterproof stamping ink. Dry using a heat gun or iron then apply to surfaces using craft glue or any of the above methods.
You can also use embossing powder with Lazertran. Use an iron through the backing paper or heat gun to set. When using embossed image you cannot use the pure turpentine method it is best to use craft glue to apply the stamped or embossed transfers.


LAZERTRAN ON METAL FOIL.

Simply iron onto the foil. Turn over and iron again to make sure it is well stuck. Immerse in water and remove backing sheet. When dry the foil can be reheated to make sure of full adhesion.

LAZERTRAN AS AN ETCH RESIST.

1. Copy image in black and white and negative using a colour photocopier onto a sheet of Lazertran.
(Now you should make sure the toners have been melted onto the Lazertran properly by putting the sheet into a hot oven In a short time the black toner will go shiny. This will avoid bubbles forming later in the process). Now cut to the size of your etching plate.
2. Soak in water for a minute or so, then place the transfer, image side down, onto the degreased plate, slide off the backing paper, then, using a soft rubber squeegee, expel all air bubbles, creases and moisture.
3. Put in a domestic oven and increase the temperature from zero as slowly as possible up to 170 degrees C until the transfer melts and becomes sticky, then allow to cool. This will take at least half an hour. The first 100 degrees are crucial and must not be rushed as this can cause bubbling.
4. Place the plate in a bath of pure turpentine and wash away the decal, leaving only the toners on the plate. All traces of the slimy decal must be removed. A soft brush can be used. This will take about 20 minutes.
5. Lift out and carefully wash off turpentine in warm soapy water.
An aqua tint can now be applied.
You are now ready to etch.

Before printing remove toners with solvent, nail polish remover or wintergreen oil or heat until melted and wipe off with rag and white spirits
Note. This method can also be used on glass and metal if you want a full colour image and wish to remove the decal.

Lazertran on Paper, Canvas, Turpentine, glass, Ceramic, Foils, Metal

Lazertran

Lazertran is a water slide decal paper that allows you to transfer your own full colour images onto almost any surface including, paper, canvas, fabric, wax, ceramic tiles, glass, sheet metals and foils, plaster, wood and stone. It can also be used as an etch resist and to make stamped and embossed decals and as a way to put images on to vacuum forming plastic.


TO FIX TO GLASS, CERAMIC TILES AND SHINY SHEET METAL AND FOILS.

For non-absorbent shiny surfaces, no glue other than the gum on the back of the transfer is required. Simply soak Lazertran in water and slide the transfer onto the carrier. Expel all air bubbles with a rubber squeegee and allow to dry for 24 hours. The image can be varnished for protection with either acrylic or oil based varnish.






TO BAKE ON CERAMICS, METAL AND GLASS TO GIVE A HARD, WATERPROOF FINISH.


1. Print your image on the shiny side of a sheet of Lazertran in reverse.

2. Put the printed sheet in a hot oven for a minute or so, or use a heat gun to make sure the toners are completely fused on the paper. The image should go very shiny. This will ensure you do not get any tiny bubbles in the image later in the process.
3. Cut the image to size and soak in luke warm water until the transfer loosens on the backing sheet.
4. Place the transfer face down onto the surface and slide the backing sheet off. Wash away any gum as this may go brown later on during the baking then squeegee flat to remove any excess water and air bubbles.
5. Put into a domestic oven at the lowest possible heat setting with the door open for 15 minutes.
6. After this close the door for a further 15 minutes.
7. Now increase the temperature very slightly and continue to do this over the next 45 minutes until the transfer becomes shiny like a glaze.
This will happen at about 200 degrees C or 420 degrees F.
As domestic ovens are not very accurate, rely on the look of the transfer rather than temperature.
The image will now be protected by the clear transfer.


INSTRUCTIONS FOR USING WATER BASED ADHESIVE METHOD FOR PAPER OR CANVAS AND FOR DECOUPAGE.

1. Stretch your paper or canvas over a flat board. Prime canvas with acrylic primer. For paper, seal with clear acrylic medium, or craft glue to avoid cockling and increase mobility of the transfer. Allow to dry.
2. Trim your image to size and lower, into clean water. The paper will roll up. Allow to soak for a minute or so.
3. Using a short haired roller or brush, apply a fresh coat of acrylic onto the area to which you wish to fix the image,
4. Lift the Lazertran out of the water and partly slide the transfer off the backing sheet.
5. Lay the Lazertran onto the wet acrylic. Position and slide out backing sheet from under the transfer.
6. Position your image, then carefully expel air bubbles with the roller.
7. Allow to dry flat overnight. Matt acrylic medium can then be applied to give a matt finish.
The application of overlays and decoupage is as above.
To apply images over oil paint see Fixing with pure turpentine.




Using real turpentine to melt the decal into the surface

This will melt the decal into absorbent surfaces such as wood, making the image part of the surface.
1.     While soaking the image in water
2.     Paint the wood etc. with a good coat of real turpentine (white spirit or substitutes will not work).
3.     Apply the damp decal, image side up, onto the turpentine painted wood, carefully removing any air bubbles.
4.     Leave for several hours.
Finishing
After application the decal will dry with a white background. To make this clear and show the surface colour and texture below, apply 2 or 3 coats of any oil/spirit based varnish. Good ones are polyurethane, and sprays like Holts Clear Car Lacquer all applied in fine coats until the finish is shiny.

For more Lazertran products with different applications please see the Lazertran website, which has instructions and other information.

Lazertran - How to use.


Lazertran

Lazertran is a water slide decal paper that allows you to transfer your own full colour images onto almost any surface including, paper, canvas, fabric, wax, ceramic tiles, glass, sheet metals and foils, plaster, wood and stone. It can also be used as an etch resist and to make stamped and embossed decals and as a way to put images on to vacuum forming plastic.



How to use Lazertran Inkjet


1.     Print your image on to the smooth, white, eggshell/chalky side of the paper. Do not use too much ink as this will cause the image to bleed. For Epson printers set to plain paper. Go into custom and then advanced and select a high DPI setting such as 1440 or as high as a quality as is available. Now click off high speed to avoid putting on too much ink. For basic HP's draft is a good setting.
2.     Allow the ink to dry for at least 30 minutes.
3.     Cut to size and soak in 3water until te decal releases from the backing sheet, about 60 seconds.
4.     For a smooth nonabsorbent surfaces such as glass, glazed ceramics and metal there will be enough gum on the back of the decal to fix the decal on to the surface. A good trick to get really good adhesion is to apply a little Methylated Spirits (Alcohol) to the surface and apply the wet decal onto this. The alcohol will stop any edges curling when drying and will make the decal soft enough to be stretched around any doubles curves. But be careful, not too much!
5.     For more absorbant surfaces such as wood or plaster extra glue will be required.

Brush Care


Brush Care


Before using for the first time.
If brush's hair is fixed by a protective substance Before using the brush, put it into a glass of water with a temperature less than 50 C (122 F) for 5-10 minutes.
After that rinse it out in clean water.

After-Painting Care
After painting, rinse a brush thoroughly trying to remove all the paint.
Use an appropriate solvent.
Type of paint
Solvent
Brush can be left in the solvent for no longer than
Oil paints
White spirit
Turpentine
1 hour
1 hour
Acrylic paints, Water Colours, or Gouche
Water with temperature 45-55 C (113-131 F)
1 hour

Do not leave brushes in solvent for any longer than stated above as this could result in a hair loss. After taking the brush out of the solvent rinse its hair in the water and dry it out at room temperature.

Keeping The Hair Shape
Don't leave brush's hair in the contact with a bottom of the glass with a solvent even for a short time. Hair might lose its shape forever. Use a glass with a special brush's holder to prevent the hair from contact with the walls or bottom of the glass.
Hair of a dry brush could also lose its shape. Keep a brush horizontally or on the handle
(hair up).
When using acrylic paint rinse your brushes regularly in water, this helps to stop paint drying on the brush. Acrylic paints dry out fast especially near a ferrule and the paint is difficult to remove afterwards.
Sometimes if hair has lost its shape you might recover the shape by putting the brush into water at a temperature of 80-90 C (176-194 F) for 2-3 minutes.

The Other Recommendations
Don't press on a brush while picking up a paint, painting or rinsing the brush
(Especially, if it has a soft hair).
Always rinse a brush in the water after using a solvent.
If you don't use a brush for a long time keep it in a closed box.

Colour Shapers

Colour Shapers are highly versatile painting tools, with a silicone tip.
