Question: Can you please describe how dye sublimation printing works? What sort of printer can be used? Would it be just like heat transfer printing?
Answer: Wow! All great and related inquiries to the dye sub and heat transfer printing of fabric, one among my favorite approaches to print fabric as well as other items, even if this answer will deal mostly with polyester fabric.
First, there are two kinds of sublimation transfer paper. One uses ribbon so transfer color to some transfer paper, along with the other is the same basic printing method as digital printing except you will find differences between ink and dye. And also the same printers can be utilized, although not interchangeably due to 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 means Cyan-Magenta, Yellow, and Black, which in almost any combination will print just about any color, excluding neon colors or metallic colors, but a majority of colors inside the photo spectrum.
As a result of limitations of CMYK inks, additional colors have already been included in some printers which are now generally known as 6 color digital printers, having added a light cyan along with a light magenta to attain a few of the harder colors to make in the printing process. Some printers have even added orange and green cartridges too.
Dye sublimation printing is slightly different. The dyes used act like ink, though with some differences. The ink looking for dye sub printing can be another four color process (commonly known in shorthand as 4CP), however the shorthand version the following is CMYO, or cyan-magenta-yellow-overprint clear. Where is definitely the black, you might wonder? It might be hard to generate a full color spectrum without black!
To spell out in which the black went, or rather more accurately, where it comes from in CMYO dye sublimation printing, I have to delve into most of how it works. As mentioned previously, a typical 4CP printing device is necessary to print dyes too, although the dye must be printed on a treated paper cleverly named “transfer paper.”
A picture is printed in reverse (or mirror printed) about the kiian sublimation ink. The paper is matched as much as a component of fabric. The material can not be an organic fiber due to process which will be explained momentarily. The material typically used more often than not is polyester as it is a flexible fiber that could be intended to look like anything from an oil canvas to a sheer fabric to some double-sided knit material that may be made into a double-sided flag or banner.
When the paper is matched on the fabric, it can be run through heated rollers at high-pressure. The rollers are heated to simply under 400 degrees Fahrenheit or 210 degrees Celsius. Since the fabric goes through the heated rollers, a couple of things happen. First, the pores or cells in the poly-fabric open up, while simultaneously the dye about the paper is changed into a gaseous state. The gas impregnates the open cells which close because they leave the heated rollers. This results in a continuous tone print which should not be achieved utilizing an computer printer due to the dot pattern laid down through the inkjets.
If an item for example plastic or aluminum is coated using a special polymeric coating, these materials can be printed. Besides banners and posters and flags, other items that are commonly dexupky33 with dye sublimation heat transfer printing are clothing items including T-shirts, table covers, sportswear, ID cards, and signs.
Some benefits of heat transfer film is the fact that image is a part of the fabric, so that it doesn’t remove like ink on the outside of fabric or any other materials and definately will not fade for several years. The dye cannot build up on fabric like t-shirts either. Everyone had worn a printed shirt the location where the ink felt as if it was very stiff on the outside of your material, and also over time it will start to flake off. This can not happen with dye sublimation.
Other advantages are how the colors might be more brilliant than other kinds of printing due to the process of dye sublimation as well as the continuous tones that are achieved when the dye converts into a gaseous state. Because in printing garments the fabric is printed before the shirt or jacket is constructed, the picture can proceed to the side of the material that is not achievable typically with screen printed shirts.
