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.
Unlike a spirit duplicator master, a hectograph master is not a mirror image. Thus, when using a spirit duplicator master with a hectograph, one writes on the back of the purple sheet, using it like carbon paper to produce an image on the white sheet, rather than writing on the front of the white sheet to produce a mirror image on its back.
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.
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.
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.
A thermal printer Bills and receipts are typically printed on thermal paper. [1]Thermal printing (or direct thermal printing) is a digital printing process which produces a printed image by passing paper with a thermochromic coating, commonly known as thermal paper, over a print head consisting of tiny electrically heated elements.
