Specifications

Screen printing is a printing technique that uses a woven mesh to support an ink-blocking stencil to receive a desired image. The attached stencil forms open areas of mesh that transfer ink or other printable materials which can be pressed through the mesh as a sharp-edged image onto a substrate. A fill blade or squeegee is moved across the screen stencil, forcing or pumping ink through the mesh openings to wet the substrate during the squeegee stroke. Basically, it is the process of using a mesh-based stencil to apply ink onto a substrate, whether it be t-shirts, posters, stickers, vinyl, wood, or other material.

Screen printing is also a stencil method of print making in which a design is imposed on a screen of polyester or other fine mesh, with blank areas coated with an impermeable substance. Ink is forced into the mesh openings by the fill blade or squeegee and onto the printing surface during the squeegee stroke. As the screen rebounds away from the substrate the ink remains on the substrate. It is also known as silkscreen, serigraphy, and serigraph printing. One colour is printed at a time, so several screens can be used to produce a multicoloured image or design.

In the past, specialty printing was limited to a handful of inks like high density, puff, glow and metallics. New inks are coming on to the market all the time and there are probably some new inks that can be combined to create an effect you’ve never imagined possible

Products

Screen printing materials

Caviar beads
    A caviar bead is a glue that is printed in the shape of the design, to which small plastic beads are then applied – works well with solid block areas creating an interesting tactile surface.
Cracking ink
    Cracking ink effect is when the ink produces an intentional cracked surface after drying.
Discharge inks
    Discharge ink is used to print lighter colours onto dark background fabrics, they work by removing the dye of the garment – this means they leave a much softer texture. The cons with this process is that they are less graphic in nature than plastisol inks, and exact colours are difficult to control. One of the pros of using this process is they are especially good for distressed prints and under-basing on dark garments that are to be printed with additional layers of plastisol. It adds variety to the design or gives it that natural soft feel.
Expanding ink (puff)
    Expanding ink, or puff, is an additive to plastisol inks which raises the print off the garment, creating a 3D feel and look to the design. Mostly used when printing on apparel.
Flocking
    Flocking consists of a glue printed onto the fabric and then flock material is applied for a velvet touch.
Foil
    Foil is much like flock, but instead of a velvet touch and look it has a reflective/mirror look to it. Although foil is finished with a heat press process it needs the screen printing process in order to add the adhesive glue onto the material for the desired logo or design.
Four colour process or the CMYK colour model
    Four colour process is when the artwork is created and then separated into four colours (CMYK) which combine to create the full spectrum of colours needed for photographic prints. This means a large number of colours can be simulated using only 4 screens, reducing costs, time, and set-up. The inks are required to blend and are more translucent, meaning a compromise with vibrancy of colour.
Glitter/Shimmer
    Glitter or Shimmer ink is when metallic flakes become an additive in the ink base to create this sparkle effect. Usually available in gold or silver but can be mixed to make most colours.
Gloss
    Gloss ink is when a clear base laid over previously printed inks to create a shiny finish.
Metallic
    Metallic ink is similar to glitter, but smaller particles suspended in the ink. A glue is printed onto the fabric, then nano-scale fibers applied on it. This is often purchased already made.
Mirrored silver
    Mirrored silver is a highly reflective, solvent based ink.
Nylobond
    Nylobond is a special ink additive for printing onto technical or waterproof fabrics.
Plastisol
    Plastisol is the most common ink used in commercial garment decoration. Good colour opacity onto dark garments and clear graphic detail with, as the name suggests, a more plasticized texture. This print can be made softer with special additives or heavier by adding extra layers of ink. Plastisol inks require heat (approx. 150 °C (300 °F) for many inks) to cure the print.
PVC and Phthalate Free
    PVC and Phthalate Free is relatively new breed of ink and printing with the benefits of plastisol but without the two main toxic components. It also has a soft texture.
Suede Ink
    Suede ink is a milky coloured additive that is added to plastisol. With suede additive you can make any color of plastisol have a suede feel. It is actually a puff blowing agent that does not bubble as much as regular puff ink. The directions vary from manufacturer to manufacturer, but generally up to 50% suede can be added to normal plastisol.
Water-Based inks
    these penetrate the fabric more than the plastisol inks and create a much softer feel. Ideal for printing darker inks onto lighter coloured garments. Also useful for larger area prints where texture is important. Some inks require heat or an added catalyst to make the print permanen
