Question: Is it possible to please describe how dye sublimation printing works? What sort of printer is utilized? Is it similar to heat transfer printing?
Answer: Wow! All very good and related inquiries to the dye sub and also heat transfer printing of fabric, among my favorite approaches to print fabric and other items, even if this answer will deal mostly with polyester fabric.
First, there are 2 forms of sublimation paper roll. One uses ribbon so transfer color to a transfer paper, along with the other is identical basic printing method as digital printing except there are actually differences between ink and dye. And the same printers can be used, however, not interchangeably because of the differences between dyes and ink.
Inkjet printing uses, typically, what is known as the “four color process” printing method. The four colors may also be known in shorthand as CMYK ink colors. CMYK is short for Cyan-Magenta, Yellow, and Black, which in virtually any combination will print almost any color, excluding neon colors or metallic colors, but a majority of colors in the photo spectrum.
Due to the limitations of CMYK inks, additional colors are already put into some printers that are now known as 6 color digital printers, having added a light cyan and a light magenta to achieve a few of the harder colors to generate inside the printing process. Some printers have even added orange and green cartridges as well.
Dye sublimation printing is slightly different. The dyes used act like ink, however with some differences. The ink set for dye sub printing can be another four color process (also known in shorthand as 4CP), but the shorthand version this is CMYO, or cyan-magenta-yellow-overprint clear. Where is definitely the black, you could possibly wonder? It might be hard to make a full color spectrum without black!
To describe in which the black went, or rather more accurately, where it comes from in CMYO dye sublimation printing, I have to delve into the remainder of the way it works. As mentioned previously, a regular 4CP laser printer is necessary to print dyes also, but the dye needs to be printed on a treated paper cleverly named “transfer paper.”
A picture is printed in reverse (or mirror printed) in the dye sublimation ink. The paper is matched to a part of fabric. The fabric cannot be an all-natural fiber due to the process which will be explained momentarily. The material typically used more often than not is polyester since it is an adaptable fiber that could be made to look like anything from an oil canvas to some sheer fabric to a double-sided knit material that could be made in to a double-sided flag or banner.
As soon as the paper is matched for the fabric, it is run through heated rollers at high pressure. The rollers are heated to simply under 400 degrees Fahrenheit or 210 degrees Celsius. As the fabric goes through the heated rollers, a couple of things happen. First, the pores or cells of the poly-fabric open, while simultaneously the dye on the paper is changed into a gaseous state. The gas impregnates the open cells which close as they leave the heated rollers. This results in a continuous tone print which cannot be achieved utilizing an computer printer as a result of dot pattern laid down through the inkjets.
If an item for example plastic or aluminum is coated with a special polymeric coating, these items can even be printed. Besides banners and posters and flags, other things which are commonly dexupky33 with dye sublimation heat transfer printing are clothing items such as T-shirts, table covers, sportswear, ID cards, and signs.
Some benefits to heat transfer film is the fact that image is an element of the fabric, therefore it doesn’t peel off like ink on top of fabric or some other materials and may not fade for many years. The dye cannot build-up on fabric like t-shirts either. Everyone had worn a printed shirt the location where the ink felt want it was very stiff on the outside from the material, as well as over time that it will start to flake off. This will not occur with dye sublimation.
Other advantages are that this colors may be more brilliant than other kinds of printing because of the process of dye sublimation as well as the continuous tones which are achieved once the dye converts to a gaseous state. Because in printing garments the material is printed ahead of the shirt or jacket is constructed, the picture can proceed to the edge of the fabric which happens to be not achievable typically with screen printed shirts.
