Sublimation printing, also known as heat transfer or paper print, it is one of the most popular processes in the industry due to the following advantages.
No screen set up costs
No minimums (d
epending on producer)
Ease in creating panel prints due to small press machines
Highly detailed prints can be achieve
Known as CIS or Bulk Ink System, it is a sublimation ink kit designed to fit a certain model of printer and is supported by software to calibrate colour settings.
Inside a dye-sublimation printer, is a long roll of transparent film that resembles sheets of red, blue, yellow, and gray coloured cellophane stuck together end to end. The print head heats up as it passes over the film, causing the dyes to vaporize and permeate the glossy surface of the paper before they return to solid form
• The heat from the thermal printing head causes the atoms of the dye in the ribbon to excite. The amount of energy from the heat exceeds the amount of energy needed for the dye to move from the solid phase to the liquid phase, and the dye turns directly to gas (sublimates).
• The transfer paper typically is placed into a heat press with the substrate and exposed to temperatures from 350 to 400 degrees Fahrenheit. This allows the ink and transfer material to move into the gas state.
• Once the ink and transfer material are in a gas state, they permeate the fibers of the substrate material.
• When the heat is removed from the transfer paper and substrate, the ink that has permeated the substrate fibers solidifies and is locked permanently into place by the transfer material.
• Assuming the procedure has been performed correctly, the image should never be subject to deterioration beyond that of the substrate itself.
• There is an alternate method for dye sublimation printing where the ink is applied directly to a substrate that has been coated. Ink bonding is achieved by exposing the fabric to heat.
