A vinyl cutter is a type of computer-controlled machine. Small vinyl cutters look like a desktop printer. Like a printer controls a nozzle, the computer controls the movement of a sharp blade over the surface of the material. This blade is used to cut out shapes and letters from sheets of thin self-adhesive plastic (vinyl). The vinyl can then be stuck to a variety of surfaces depending on the adhesive and type of material.
To cut out a design a vector-based image must be created in a software program (usually Adobe Illustrator or Corel Draw). It is then sent to the cutter where it cuts along the vector paths laid out in the design. The cutter is capable of moving the blade on an X and Y axis over the material, cutting it into any shape imaginable. Since the vinyl material comes in long rolls, projects with significant length like banners or billboards can be easily cut as well.
The one major limitation with vinyl cutters is that they can only cut shapes from solid colours of vinyl. A design with multiple colours must have each colour cut separately and then layered on top of each other as it is applied to the substrate. Also, since the shapes are cut out of solid colours, photographs and gradients cannot be reproduced with a stand alone cutter.
In addition to the capabilities of the cutter itself, the adhesive vinyl comes in a wide variety of colours and materials including gold and silver foil, vinyl that simulates frosted glass, holographic vinyl, reflective vinyl, thermal transfer material, and even clear vinyl imbedded with gold leaf. (Often used in the lettering on fire trucks and rescue vehicles.)
How it works
As vinyl film is supplied by the manufacturer, it comes attached to a release liner.
Computer designed images are loaded onto the vinyl cutter via cords or over wifi depending on the model. Then the vinyl is loaded into the machine where it is automatically fed through and cut to follow the set design.
The vinyl cutter uses a small knife to precisely cut the outline of figures into a sheet or piece of vinyl, but not the release liner. The knife moves side to side and turns, while the vinyl is moved beneath the knife. The results from the cut process is an image cut into the material.
The material is then 'weeded' where the excess parts of the figures are removed from the release liner. It is possible to remove the positive parts, which would give a negative sticker, or remove the negative parts, giving a positive sticker. Removing the figure would be like removing the positive, giving a negative image of the figures.
A sheet of transfer tape with an adhesive backing is laid on the weeded vinyl. A roller is applied to the tape, causing it to adhere to the vinyl. The transfer tape and the weeded vinyl is pulled off the release liner, and applied to a substrate, such as a sheet of aluminium. This results in an aluminium sign with vinyl figures.
The vinyl cutter is an entry level machine for making signs. Computer designed vector files with patterns and letters are directly cut on the roll of vinyl which is mounted and fed into the vinyl cutter through USB or serial cable. Vinyl cutters are mainly used to make signs, banners and advertisements. Advertisements seen on automobiles and vans are often made with vinyl cut letters. While these machines were designed for cutting vinyl, they can also cut through computer and specialty papers, as well as thicker items like thin sheets of magnet.
In addition to sign business, vinyl cutters are commonly used for apparel decoration. To decorate apparel, a vector design needs to be cut in mirror image, weeded, and then heat applied using a commercial heat press or a hand iron for home use.
Some businesses use their vinyl cutter to produce both signs and custom apparel. Many crafters also have vinyl cutters for home use. These require little maintenance and the vinyl can be bought in bulk relatively cheaply.
