A dye-sublimation printer (or dye-sub printer) is a computer printer which employs a printing process that uses heat to transfer dye onto materials such as a plastic, card, paper, or fabric. The sublimation name was first applied because the dye was considered to make the transition between the solid and gas states without going through a liquid stage.
This understanding of the process was later shown to be incorrect. Since then, the process is sometimes known as dye-diffusion, though this has not eliminated the original name. Many consumer and professional dye-sublimation printers are designed and used for producing photographic prints and so on.
These are not to be confused with dye sublimation heat transfer imprinting printers, which use special inks to create transfers designed to be imprinted on textiles, and in which the dyes do indeed sublimate. Some dye-sublimation printers use CMYO (Cyan Magenta Yellow Over coating) colors, which differs from the more recognized CMYK colors in that the black is eliminated in favour of a clear over coating. This over coating (which has numerous names depending on the manufacturer) is also stored on the ribbon and is effectively a thin layer which protects the print from discoloration from UV light and the air, while also rendering the print water-resistant.
Wide Format Printing
Wide format or wide format printers are generally accepted to be any computer-controlled printing machines that support a maximum print roll width of between 1.2m and 2.6m. Printers with capacities over 2.5m wide are considered Super Wide or Grand format.
Wide format printers are used to print banners, posters, trade show graphics, wallpaper, murals, backlit film, vehicle image wraps, electronic circuit schematics, architectural drawings, construction plans, backdrops for theatrical and media sets, and any other large format artwork or signage.
Wide format printers usually employ some variant of inkjet technology to produce the printed image; and are more economical than other print methods such as screen printing for most short-run (low quantity) print projects, depending on print size, run length (quantity of prints per single original), and the type of substrate or print medium. Wide format printers are usually designed for printing onto a roll of print media that feeds incrementally during the print process, rather than onto individual sheets.
Lithographic printing is well suited for printing both text and illustrations in short to medium length runs of up to 1,000,000 impressions. Typical products printed with offset printing processes include:
- General commercial printing Quick printing
- Newspapers Books
- Business Forms Financial and Legal Documents
- Offset Lithographic Printing Process Overview
Lithography is an “offset” printing technique. Ink is not applied directly from the printing plate (or cylinder) to the substrate as it is in gravure, flexography and letterpress. Ink is applied to the printing plate to form the “image” (such as text or artwork to be printed) and then transferred or “offset to a rubber “blanket”. The image on the blanket is then transferred to the substrate (typically paper or paperboard) to produce the printed product.
Digital printing refers to methods of printing from a digital-based image directly to a variety of media. It usually refers to professional printing where small-run jobs from desktop publishing and other digital sources are printed using large-format and/or high-volume laser or inkjet printers. Digital printing has a higher cost per page than more traditional offset printing methods, but this price is usually offset by avoiding the cost of all the technical steps required to make printing plates. It also allows for on-demand printing, short turnaround time, and even a modification of the image (variable data) used for each impression. The savings in labor and the ever-increasing capability of digital presses means that digital printing is reaching the point where it can match or supersede offset printing technology’s ability to produce larger print runs of several thousand sheets at a low price.
we have created from the beginning of time.
At Moleko Printers we design and print to perfection. Although our printing services are separated into four main categories,
Digital Printing – Wide Format Printing – Litho Printing – DYE Sublimations
we want our clients to know what these categories actually represent.
