Question: Can you please describe how dye sublimation printing works? What sort of printer is utilized? Will it be similar to heat transfer printing?
Answer: Wow! All very good and related questions to the dye sub and heat transfer printing of fabric, one of the most popular methods to print fabric along with other items, although this answer will deal mostly with polyester fabric.
First, there are two forms of sublimation transfer 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 actually differences between ink and dye. And also the same printers works extremely well, while 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 can also be known in shorthand as CMYK ink colors. CMYK stands for Cyan-Magenta, Yellow, and Black, which in any combination will print almost any color, excluding neon colors or metallic colors, but the majority colors within the photo spectrum.
Because of the limitations of CMYK inks, additional colors have already been added to some printers which are now referred to as 6 color digital printers, having added a mild cyan along with a light magenta to arrive at some 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 are similar to ink, although with some differences. The ink looking for dye sub printing is also a four color process (commonly known in shorthand as 4CP), however the shorthand version this is CMYO, or cyan-magenta-yellow-overprint clear. Where is the black, you may wonder? It could be hard to make a full color spectrum without black!
To describe where the black went, or rather better, where it will come from in CMYO dye sublimation printing, I need to explore the remainder of the way it works. As mentioned previously, an ordinary 4CP laser printer is necessary to print dyes too, but the dye should be printed with a treated paper cleverly named “transfer paper.”
A picture is printed in reverse (or mirror printed) on the ink sublimation. The paper is matched to a component of fabric. The fabric can not be an all natural fiber due to the process that will be explained momentarily. The material typically used more often than not is polyester since it is an adaptable fiber that can be intended to seem like anything from an oil canvas into a sheer fabric to a double-sided knit material that may be made into a double-sided flag or banner.
After the paper is matched towards the fabric, it is actually run through heated rollers at high pressure. The rollers are heated to simply under 400 degrees Fahrenheit or 210 degrees Celsius. Since the fabric experiences the heated rollers, a couple of things happen. First, the pores or cells of your poly-fabric start, 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 cannot be achieved utilizing an inkjet printer as a result of dot pattern laid down through the inkjets.
If the item such as plastic or aluminum is coated by using a special polymeric coating, these materials can also be printed. Besides banners and posters and flags, other considerations which 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 vinyl would be that the image is a part of the fabric, so that it doesn’t peel off like ink on top of fabric or any other materials and can not fade for a long time. The dye cannot build up on fabric like t-shirts either. Everyone had worn a printed shirt where the ink felt enjoy it was very stiff on the outside in the material, and over time that it will begin to flake off. This will likely not occur with dye sublimation.
Other advantages are the colors might be more brilliant than other sorts of printing due to technique of dye sublimation and also the continuous tones that happen to be achieved as soon as the dye converts into a gaseous state. Because in printing garments the material is printed before the shirt or jacket is constructed, the picture can visit the side of the material which is not achievable typically with screen printed shirts.
