Dry transfer is a term used to describe decals which can be applied without the use of water or other solvent. Sometimes they are called rub-ons or rubdowns due to the method of application. The decal itself is on a backing material such as paper or plastic sheeting. The backing is placed, decal side down, on the surface to transfer to, and then it is applied by rubbing with a stylus, ballpoint pen, pencil, etc.
Example situations: rubbing off drytransfer letters, tracing designs onto a new surface with carbon paper, and hand embossing.
In various instruments this method may be used instead of a pen for recording as it has the advantage of being able to operate over a wide temperature range, does not clog or dry prematurely, and has very small friction in comparison to other methods.
These characteristics were useful in certain types of early seismographs and in recording barographs used in determining sailplane altitude records.
Powdered toner particles become charged and are then attracted to the drums, and are transferred and fused to a medium (paper or plastic sheeting).
Color laser printers usually use four drums, one for each process color (cyan, magenta, yellow and fl), the medium being sequentially fed to and from each drum assembly.
lithography A process of printing by transferring an image drawn with an oil-based material on stone or metal plate to paper or other medium.
