MGMT 1050 Tutorial 8 Notes – Thermal Wax Transfer and Dye Sublimation Printers
Introduction
• The preferred methods are thermal wax transfer and dye sublimation.
• The mechanisms for both types are similar.
• The paper is fed into the printer and clamped against a drum.
• A print head provides a row of dot-sized heating elements.
• Between the paper and the print head, the printer feeds a roll of film that is
impregnated with either colored wax or dye.
• The film is made up of page-sized sections of magenta, cyan, and yellow colors
• Sometimes an additional section of black is also included.
• Each rotation of the drum exposes the paper to a different color.
• The heat from the print head melts the wax or dye onto the paper.
• Thermal wax can be applied to ordinary paper.
• To improve quality, some printers pre-coat the paper with clear wax.
• This compensates for slight imperfections in the paper so that the wax may be applied
more uniformly.
• Different colors are produced in the same way that black-and-white printers produce
gray scales.
• The dye sublimation technique differs slightly, in that transparent dyes diffuse in the
paper, so that the dots of color actually blend.
• Furthermore, it is possible to control the amount of dye by adjusting the temperature of
individual print head elements.
• Thus, dye sublimation can print continuous color tones. Unfortunately, the dye
sublimation technique also requires higher temperatures
• Therefore, special paper must be used.
• Users use a variety of devices to interact with the computer.
• The paper and the print head, the printer feeds a roll of film that is impregnated with
either colored wax or dye.
