Vacuum-formed graphics
Material
Special plastic foil formed in heated conditions.
Special technology
Thermoform – a machine which facilitates the heating of a foil laid upon a matrix, and the siphoning off of air from its other side by vacuum pump.
Preparation of source materials
-
Relief matrix made of a material resistant to the temperature of the thermoform.
-
May be prepared by hand or printed out via 3-D printer – it is limited in height (maximum of ca. 2.5 cm) and in size (A3).
The production process
-
Preparation of a relevant matrix with respect to the principles of tactile graphics.
-
Printing the matrix upon a foil – in the heated thermoform, the foil will be placed upon the matrix, and subjected to very high temperature, subsequently the air between the matrix and the foil is siphoned off – this accomplishes strong adhesion of the foil to the matrix.
Advantages
-
the possibility of creating multi-layered graphics, and higher relief in general
-
the resultant graphic is very distinctive and pleasant in concern to perception; based on the weight of the foil used it is also quite durable
-
relatively low cost of the operation of the thermoform (low cost of foil)
-
the graphics are easy to be maintained in good condition
Disadvantages
-
relatively high cost of the thermoform
-
matrix preparation is demanding time and technology-wise
-
based on materials used, the matrix may deteriorate
-
archiving of matrices is difficult
