Question: Is it possible to please describe how dye sublimation printing works? What kind of printer is commonly used? Would it be exactly like heat transfer printing?
Answer: Wow! All excellent and related questions to the dye sub as well as heat transfer printing of fabric, certainly one of my personal favorite approaches to print fabric and also other items, even though this answer will deal mostly with polyester fabric.
First, there are 2 varieties of sublimation paper. One uses ribbon so transfer color to some transfer paper, and the other is identical 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 because of the differences between dyes and ink.
Inkjet printing uses, typically, what is known the “four color process” printing method. The 4 colors are also known in shorthand as CMYK ink colors. CMYK represents Cyan-Magenta, Yellow, and Black, which in any combination will print virtually any color, excluding neon colors or metallic colors, but most colors inside the photo spectrum.
Due to limitations of CMYK inks, additional colors are already put into some printers that are now referred to as 6 color digital printers, having added an easy cyan plus a light magenta to reach some of the harder colors to produce from the printing process. Some printers have even added orange and green cartridges also.
Dye sublimation printing is slightly different. The dyes used act like ink, though with some differences. The ink set for dye sub printing can be another four color process (commonly known in shorthand as 4CP), however the shorthand version is CMYO, or cyan-magenta-yellow-overprint clear. Where is definitely the black, you could possibly wonder? It would be hard to generate a full color spectrum without black!
To describe where the black went, or rather better, where it appears from in CMYO dye sublimation printing, I need to explore the remainder of the way it works. As mentioned previously, a typical 4CP inkjet printer is necessary to print dyes at the same time, although the dye needs to be printed with a treated paper cleverly named “transfer paper.”
An image is printed in reverse (or mirror printed) on the dye sublimation ink. The paper is matched to a part of fabric. The fabric should not be an organic fiber due to process that can be explained momentarily. The fabric typically used usually is polyester because it is an adaptable fiber that may be made to seem like everything from an oil canvas into a sheer fabric to your double-sided knit material that could be made in to a double-sided flag or banner.
Once the paper is matched towards 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 being the fabric undergoes the heated rollers, a couple of things happen. First, the pores or cells in the poly-fabric open up, 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 creates a continuous tone print which can not be achieved utilizing an laser printer due to dot pattern laid down from the inkjets.
If an item like plastic or aluminum is coated having a special polymeric coating, these items can also be printed. Besides banners and posters and flags, other things which are commonly dexupky33 with dye sublimation heat transfer printing are clothing items for example T-shirts, table covers, sportswear, ID cards, and signs.
Some benefits of wholesale heat transfer vinyl is that the image is an element of the fabric, thus it doesn’t peel off like ink on the outside of fabric or another materials and may not fade for several years. The dye cannot increase on fabric like t-shirts either. Everyone had worn a printed shirt where the ink felt as if it was very stiff on top from the material, and over time it will start to flake off. This may not happen with dye sublimation.
Other advantages are that this colors could be more brilliant than other kinds of printing because of the procedure of dye sublimation along with the continuous tones which are achieved as soon as the dye converts into a gaseous state. Because in printing garments the fabric is printed prior to the shirt or jacket is constructed, the photo can visit the side of the fabric that is not achievable typically with screen printed shirts.
