Question: Are you able to please describe how dye sublimation printing works? Which kind of printer is used? Is it the same as heat transfer printing?
Answer: Wow! All very good and related inquiries to the dye sub as well as heat transfer printing of fabric, certainly one of my favorite ways to print fabric and other items, even if this answer will deal mostly with polyester fabric.
First, there are 2 forms of transfer paper. One uses ribbon so transfer color to a transfer paper, and the other is the same basic printing method as digital printing except there are differences between ink and dye. And the same printers can be utilized, while not interchangeably because of the differences between dyes and ink.
Inkjet printing uses, typically, what is known 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 almost any combination will print nearly every color, not including neon colors or metallic colors, but many colors within the photo spectrum.
Because of the limitations of CMYK inks, additional colors happen to be put into some printers which are now generally known as 6 color digital printers, having added an easy cyan as well as a light magenta to achieve several of the harder colors to generate inside the printing process. Some printers have even added orange and green cartridges at the same time.
Dye sublimation printing is slightly different. The dyes used are like ink, though with some differences. The ink looking for dye sub printing is another four color process (best known in shorthand as 4CP), but the shorthand version is CMYO, or cyan-magenta-yellow-overprint clear. Where is definitely the black, you could wonder? It could be hard to create a full color spectrum without black!
To spell out where black went, or rather better, where it appears from in CMYO dye sublimation printing, I need to look into most of the way it works. As stated previously, a typical 4CP inkjet printer is needed to print dyes too, but the dye needs to be printed with a treated paper cleverly named “transfer paper.”
A photo is printed in reverse (or mirror printed) in the neon sublimation ink. The paper is matched as much as a component of fabric. The material cannot be an all-natural fiber due to the process that can be explained momentarily. The material typically used quite often is polyester because it is a flexible fiber that could be designed to seem like everything from an oil canvas to a sheer fabric into a double-sided knit material that could be made in a double-sided flag or banner.
After the paper is matched for the fabric, it is run through heated rollers at high pressure. The rollers are heated to merely under 400 degrees Fahrenheit or 210 degrees Celsius. Because the fabric experiences the heated rollers, a couple of things happen. First, the pores or cells of the poly-fabric open, while simultaneously the dye in the paper is changed into a gaseous state. The gas impregnates the open cells which close while they leave the heated rollers. This results in a continuous tone print which should not be achieved having an computer printer due to dot pattern laid down through the inkjets.
If an item for example plastic or aluminum is coated using a special polymeric coating, these items can be printed. Besides banners and posters and flags, other considerations 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 advantages to heat transfer vinyl roll would be that the image is an element of the fabric, thus it doesn’t remove like ink on top of fabric or other materials and will not fade for many years. The dye cannot develop on fabric like t-shirts either. Everyone had worn a printed shirt where ink felt as if it was very stiff on top of the material, as well as over time it will flake off. This will not occur with dye sublimation.
Other advantages are that this colors may be more brilliant than other printing because of the technique of dye sublimation and also the continuous tones that happen to be achieved as soon as the dye converts to a gaseous state. Because in printing garments the material is printed prior to the shirt or jacket is constructed, the picture can check out the fringe of the fabric which happens to be not achievable typically with screen printed shirts.
