The term was later also applied to the indirect sublimation transfer printing process, which uses a standard ink-jet printer to deposit sublimation-capable ink onto a transfer sheet. The printed transfer sheet is then pressed with the substrate with heat, transferring the dye to the substrate, such as plastic or fabric, via sublimation.
This ink is dried and hardened later during the heating process. The second section of the process is a vacuum system that removes excess powder from areas of the sheet that were not printed. [1] The third section of the process conveys the product through a radiant oven where it is exposed to temperatures of 900 to 1300ºF (500-700ºC). [2]
The special aniline dyes for making the master image came in the form of ink or in pens, pencils, carbon paper and even typewriter ribbon. Hectograph pencils and pens are sometimes still available. Various other inks have been found usable to varying degrees in the process; master sheets for spirit duplicators have also been pressed into ...
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.
Since the early 1990s, inkjet technology and specially developed water-based ink (known as dye-sublimation or disperse direct ink) have made it possible to print directly onto polyester fabric. This is mainly related to visual communication in retail and brand promotion (flags, banners and other point of sales applications).
Hard-copy proofing usually involves ink-jet printing or other technologies (i.e. Laminate Proof [6]) to produce high-quality one-off copies of the production artwork. Soft proofing usually involves highly color accurate wide-gamut computer displays. "The printed proof is a dispassionate simulation of the ultimate output – a CMYK press sheet.
The disperse direct ink is a ‘stronger’ ink than the dye-sub kind, and this is very important for outdoor use, such as for fence fabric, flags and banners: artwork will last longer. Another benefit of aqueous-based sublimation ink is the absence of hazardous components as found in UV-curable, solvent and, even, in latex inks.
The ink is deposited on these high-release inkjet papers, which are used for the next step of the sublimation printing process. After the digital design is printed onto sublimation transfer sheets, it is placed on a heat press along with the substrate to be sublimated. [citation needed]
