Question: Could you please describe how dye sublimation printing works? Which kind of printer is utilized? Could it be exactly like heat transfer printing?
Answer: Wow! All excellent and related inquiries to the dye sub and heat transfer printing of fabric, one of my personal favorite approaches to print fabric and also other items, although this answer will deal mostly with polyester fabric.
First, there are 2 varieties of sublimation paper roll. One uses ribbon so transfer color to some transfer paper, and also the other is the same basic printing method as digital printing except there are differences between ink and dye. Along with the same printers can be used, while not interchangeably due to differences between dyes and ink.
Inkjet printing uses, typically, what is known as the “four color process” printing method. The 4 colors are also known in shorthand as CMYK ink colors. CMYK stands for Cyan-Magenta, Yellow, and Black, which in almost any combination will print almost any color, not including neon colors or metallic colors, but the majority colors inside the photo spectrum.
Due to the limitations of CMYK inks, additional colors have been added to some printers which can be now referred to as 6 color digital printers, having added a mild cyan plus a light magenta to achieve some of the harder colors to produce within 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, but with some differences. The ink looking for dye sub printing is yet another four color process (also known in shorthand as 4CP), nevertheless the shorthand version the following is CMYO, or cyan-magenta-yellow-overprint clear. Where is definitely the black, you may wonder? It might be hard to make a full color spectrum without black!
To spell out in which the black went, or rather better, where it appears from in CMYO dye sublimation printing, I have to delve into the rest of how it operates. As mentioned previously, a standard 4CP computer printer is needed to print dyes also, but the dye must be printed on a treated paper cleverly named “transfer paper.”
An image is printed in reverse (or mirror printed) around the ink sublimation. The paper is matched as much as a bit of fabric. The fabric should not be an all-natural fiber because of the process that might be explained momentarily. The material typically used more often than not is polyester because it is a flexible fiber that may be intended to seem like anything from an oil canvas to your sheer fabric to your double-sided knit material that could be made in a double-sided flag or banner.
As soon as the paper is matched to the fabric, it is actually run through heated rollers at high-pressure. The rollers are heated to merely 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 of your poly-fabric start, while simultaneously the dye in the paper is transformed 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 inkjet printer due to dot pattern laid down by the inkjets.
If the item like plastic or aluminum is coated having a special polymeric coating, these items can even be printed. Besides banners and posters and flags, other items which can be 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 vinyl roll would be that the image is a part of the fabric, thus it doesn’t peel off like ink on the surface of fabric or any other materials and will not fade for a long time. The dye cannot build up on fabric like t-shirts either. Everyone had worn a printed shirt where ink felt enjoy it was very stiff on the outside of the material, and over time it will flake off. This will not happen with dye sublimation.
Other advantages are that the colors could be more brilliant than other types of printing due to the technique of dye sublimation as well as the continuous tones which can be achieved as soon as the dye converts to some gaseous state. Because in printing garments the material is printed ahead of the shirt or jacket is constructed, the picture can proceed to the fringe of the fabric that is not achievable typically with screen printed shirts.
