Sign Making Vinyl

Presure sensitive self-adhesive graphic vinyl film used for the creation of signs.

Terms used to describe the manufacturing processes.

Rolls are normally purchased in 3 sizes and available in lengths normally up to 50mtrs.

  1. 380mm (15inch)
  2. 610mm (24inch)
  3. 1220mm (48inch)

Vinyl is either printed or cut on a plotter, when plotted the vinyl requires weeding and then application tape is used to prepare the graphic before applying to the surface.

Vinyl that is printed sometimes is laminated to improve the durability and lightfastness of the graphic.

Manufacturing process

Calendered

The process of passing vinyl through a set of rollers, this makes a smooth even and gloss finish. This is how production of good quality vinyl is made which is reflected in its lower cost.

Cast

The process of mixing up the ingredients and then pouring onto a running conveyer system, this then gets baked to form a strong material, you could consider the process similar to baking a cake, the material is far more forgiving for shaping and made much thinner.

Makeup of the Vinyl

Monomeric

Monomeric - A monomer is small molecules that may chemically bond to other monomers, this forms a polymer. It is generally considered to be the shortest term of useage for a vinyl and the cheapest.

Polymeric

Polymeric - A polymer is a substance composed of molecules with large molecular mass composed of repeating structural units, or monomers, connected by covalent chemical bonds. Most calendared vinyls are polymeric, this is used for vinyls up to say 7 years.

Terms

Plasticizers

These are liquids that are add during the process of making vinyls. They add flexibility to the final film. They soften the feel to the hand.

Gatorboard ®

A Multi layer composite of extremely dense and durable Polystyrene foam that resists crushing and denting. Topping the core are several Thicknesses of plastics, papers and adhesives, creating a moisture-resistant layer that helps form a rigid board that is resistant to bending or warping. The smooth paper finish offers ideal ink coverage and needs little or no preparation for mounting and laminating. It's free of toxic chemicals such as chlorofluorocarbons (CFCs) and formaldehyde

Exceptional rigidity, surface quality and durability make it the mounting board of choice for photographers and photo Mount, screen printing, signs, acrylic and oil painting and Water Colorist. The typical applications of Gatorboard is mounted photos, cut out letters, screen printed graphics, backing boards, temporary walls, parade floats, blueprint, charts, and graph mounting, and costumes.

Class A rated (combustible) asbestos-free panel, and is dimensionally stable and lighter than plywood.

Gatorboard Graphic Arts Board is claimed to be the toughest laminated foam panel you can buy. If the job calls for a rugged, durable board that resists dents and punctures, you’ll want Gatorboard and nothing else.

The exceptionally hard, smooth surface is uniform and blemish free. Photo Mounting, artists, designers, sign painters, exhibit builders, and engineers have counted on it for years.

Gatorboard has a light, durable core of polystyrene foam, bonded on both sides to patented Luxcell ® facings.

These wood fiber veneers are impregnated with a proprietary resin for integrity, durability, and moisture-resistance. Ideal for indoor or outdoor use. Sheet must be painted and sealed. Black Gatorboard not recommended for outdoors.

Gatorboard requires only standard woodworking tools for cutting and shaping. Make straight or curved lines easily with any saw — it won’t tear, chip, or shred. And you can cut angles and bevels easily. For smooth, clean irregular cuts and shapes, a standard router is all you need..
