Dye-sublimation printing (or dye-sub printing) is a term that covers several distinct digital computer printing techniques that involve using heat to transfer dye onto a substrate. The sublimation name was first applied because the dye was thought to make the transition between the solid and gas states without going through a liquid stage. This ...
Also, when compared with dye sublimation techniques, heat transfers can be used on 100% cotton garments, whereas dye sublimation requires at least a 50/50 poly cotton garment. Iron-on transfer paper is available for use with computer printers. A number of inkjet, copier and laser printer toners have been developed to utilize this process.
Screen printing is a printing technique where a mesh is used to transfer ink (or dye) onto a substrate, except in areas made impermeable to the ink by a blocking stencil.A blade or squeegee is moved across the screen in a "flood stroke" to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact.
A sublimatory [1] [2] or sublimation apparatus is equipment, commonly laboratory glassware, for purification of compounds by selective sublimation. In principle, the operation resembles purification by distillation , except that the products do not pass through a liquid phase .
Selecting a nozzle based on the pattern and other spray characteristics that are required generally yields good results. [5] Since spray nozzles are designed to perform under many different spraying conditions, more than one nozzle may meet the requirements for a given application. Surfaces may be sprayed with any pattern shape.
The sublimation that occurs at the solid-gas boundary (critical sublimation point) (corresponding to boiling in vaporization) may be called rapid sublimation, and the substance sublimes rapidly. The words "gradual" and "rapid" have acquired special meanings in this context and no longer describe the rate of sublimation. [citation needed]
Pad printing (also called tampography) is a printing process that can transfer a 2-D image onto a 3-D object (e.g., a ceramic pottery).This is accomplished using an indirect offset printing process that involves an image being transferred from the cliché via a silicone pad onto a substrate.
Recommended water temperature for the dip tank is 90°F (32°C). The clear hydrographic film is water-soluble and should dwell on top of the water for 60-75 seconds. Safely using a fitted respirator, the film is then sprayed with an activator solution to dissolve the film and return it to its fluid state.
