Question: Can you please describe how dye sublimation printing works? What kind of printer is utilized? Could it be just like heat transfer printing?
Answer: Wow! All excellent and related questions to the dye sub as well as heat transfer printing of fabric, one of the best methods to print fabric and also other items, although this answer will deal mostly with polyester fabric.
First, the two main kinds of sublimation paper. One uses ribbon so transfer color to some transfer paper, and the other is the same basic printing method as digital printing except there are differences between ink and dye. Along with the same printers works extremely well, 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 will also be known in shorthand as CMYK ink colors. CMYK is short for Cyan-Magenta, Yellow, and Black, which in any combination will print almost any color, excluding neon colors or metallic colors, but most colors in the photo spectrum.
Because of the limitations of CMYK inks, additional colors have already been put into some printers which can be now generally known as 6 color digital printers, having added an easy cyan and a light magenta to reach a number of the harder colors to generate from the printing process. Some printers have even added orange and green cartridges also.
Dye sublimation printing is slightly different. The dyes used are like ink, however with some differences. The ink set for dye sub printing is yet 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 might be hard to make a full color spectrum without black!
To clarify the location where the black went, or rather more accurately, where it will come from in CMYO dye sublimation printing, I have to look into most of how it works. As stated previously, a standard 4CP printing device is necessary to print dyes as well, however the dye must be printed on a treated paper cleverly named “transfer paper.”
A photo is printed in reverse (or mirror printed) in the kiian sublimation ink. The paper is matched up to a part of fabric. The fabric should not be an all-natural fiber due to process that will be explained momentarily. The fabric typically used more often than not is polyester since it is an adaptable fiber that may be made to seem like everything from an oil canvas to a sheer fabric to a double-sided knit material that may be made into 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 undergoes the heated rollers, a couple of things happen. First, the pores or cells of the poly-fabric open, while simultaneously the dye around the paper is changed into a gaseous state. The gas impregnates the open cells which close since they leave the heated rollers. This creates a continuous tone print which can not be achieved having an laser printer as a result of dot pattern laid down by the inkjets.
If the item such as plastic or aluminum is coated using a special polymeric coating, these things can even be printed. Besides banners and posters and flags, other things that are commonly dexupky33 with dye sublimation heat transfer printing are clothing items like T-shirts, table covers, sportswear, ID cards, and signs.
Some benefits to heat transfer vinyl sheets would be that the image is a part of the fabric, thus it doesn’t peel off like ink on the outside of fabric or other materials and definately will 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 as if it was very stiff at first glance from the material, and over time it will flake off. This can not occur with dye sublimation.
Other advantages are how the colors could be more brilliant than other sorts of printing due to process of dye sublimation and also the continuous tones which can be achieved as soon as the dye converts to some gaseous state. Because in printing garments the fabric is printed before the shirt or jacket is constructed, the graphic can check out the side of the fabric which can be not achievable typically with screen printed shirts.
