In some printing processes, dye-sublimation printers have replaced inkjet and laser printers. Advanced equipment gives a better image due to a different operating principle. So, inkjet sublimation printer in pakistan technology prints with liquid ink, and laser – with dry powder.
New hues are created by superimposing points of four primary colors: cyan, yellow, magenta, and black. These dots can shift, blur, which degrades the picture quality. In an inkjet printer, ink often dries up, in a laser printer, there is a problem with mixing powders.
The dye sublimation printer does not have these disadvantages. For printing, special ribbons with a dye of three colors (cyan, magenta, yellow) are used. Under the influence of temperature (the device is equipped with a heating element), the dye changes from a solid to a gaseous state. In this case, the stage of transformation into a liquid is excluded.
The process is called sublimation, hence the name of the technique using this technology.
The higher the heating temperature, the richer the pattern. The pores of the material open more, the dye penetrates deeper into it. To obtain a subdued, light-colored image, you need to lower the temperature.
The gaseous “cloud” consists of three colors of dyes. They are mixed in the right proportion using a diaphragm, which acts as a kind of filter, eliminating unnecessary vapors. The selected shades are transferred to the working material.
A sublimation printer in pakistan prints at a resolution of no more than 300 dpi, but the colors are very realistic, since the mixing does not take place on paper, but in the device itself under the influence of temperature.
A dye-sublimation printer can print the brightest pictures
Scope of use
The equipment is used in printing houses, photo studios. It can be used to print advertising brochures, souvenirs, magazines, photographs, posters, plastic cards. The applications of dye-sublimation printers are varied due to the versatility of the devices and the ability to work with different materials.
The dye sublimation printer is suitable for printing on a variety of media. This could be:
paper;
the cloth;
plastic;
ceramics;
glass;
metal and so on.
However, there are some limitations. So, sublimation ink does not adhere well to natural fabrics. At the same time, they are ideal for synthetics. When working with glass or stone, preliminary surface treatment with a special polymer is required.
Advantages of dye sublimation printers
Sublimation devices are quite expensive, but their purchase is justified by the following advantages:
Printing of durable images – the dye penetrates deep into the material, the protective layer seals the pattern, prevents fading, abrasion.
Better image quality at lower resolutions when compared to laser and inkjet devices. This is possible by mixing the colors before hitting the work surface.
Ease of use. Most models are equipped with displays on which operating information is displayed.
Ability to work with different materials.
The devices are not without flaws. For example: the high cost of both the device itself and consumables. Some time ago, the sensitivity of the dye to ultraviolet was considered another disadvantage of sublimation printers. Today, manufacturers use special formulations that protect the ink from sunlight, so the printed image remains bright for a long time.
Printer review: from history to modern times
The creator of sublimation printer in pakistan, as a type of printing, is considered the Frenchman Noel de Plassé. As an employee of a textile company, he noticed that some dyes are capable of converting from solid to gaseous without passing into a liquid intermediate state. This happened when the ink was heated to 190 degrees Celsius.
The discovery dates back to 1957, but it brought practical benefits only 20 years later, when personal computers began to spread around the world. At the same time, the first sublimation printer appeared.
Mass production of devices was launched in the USA. Following them, Europe and Japan joined the process. The first dye-sublimation printers printed with graphite dyes. The price of the equipment was very high, and only large companies could afford such a purchase. Today this technique has improved significantly. The range is presented by amateur and professional models. For printing, special film is used, the size of which matches the size of the media.
Sublimation equipment comes in different formats. Images are printed on it in sizes A4, A5, A6. The main printer manufacturers are Mitsubishi, Epson, Canon and Sony. The first two are focused on professional equipment for the corporate segment. Sony products are primarily suitable for private use. Canon’s portfolio includes both professional and hobbyist devices.
Let’s consider several popular models:
Canon Selphy CP910. The printer is suitable for printing photos – it takes 47 seconds for one shot. It implements the “borderless printing” option. Photo paper is used as a consumable. The maximum format is A6. The model is equipped with a Wi-Fi module, a slot for MMC and SD memory cards (you can print directly from the media). It is compact and can be powered by a built-in battery. Among the disadvantages are few opportunities for image editing, high cost of consumables.
Epson SureColor F7170. Professional printer. The maximum resolution is 720×1440 dpi. Works with DS Transfer Adhesive Textile and Multipurpose consumables. Suitable for drawings on textiles, interior printing , clothing.
Sony DPP-FP67. It is positioned as a home appliance, but its characteristics are sufficient for use in a small office. The device is mobile, compact – weighing 1 kg. Borderless printing, virtually silent. It takes about 63 seconds to create one image. The main drawback of both this and other Sony models is the difficulty in purchasing consumables.
Mitsubishi Electric CP-D90DW . Professional desktop type device. The maximum print format is 15.2×22.9 cm, the resolution is 300×300 dpi. The printer can print a 10×15 image in less than 8 seconds. Among the disadvantages is the high cost.
Outcome
A dye sublimation printer in pakistan does not print with ink or dry powder, but with a special dye on the film.
The technology is based on the property of solids to turn into gases, bypassing the liquid stage.
This technique is used in the advertising industry, in the production of souvenirs, clothing, prints, photographs, and so on.
Printing costs decrease as turnover increases. This is especially true for low-power models.
