Question: Is it possible to please describe how dye sublimation printing works? What sort of printer can be used? Would 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 ways to print fabric as well as other items, even though this answer will deal mostly with polyester fabric.
First, there are 2 types of heat transfer paper. One uses ribbon so transfer color into a transfer paper, and also the other is identical basic printing method as digital printing except there are differences between ink and dye. And 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 four colors will also be known in shorthand as CMYK ink colors. CMYK stands for Cyan-Magenta, Yellow, and Black, which in virtually any combination will print nearly every color, not including neon colors or metallic colors, but a majority of colors inside the photo spectrum.
Due to limitations of CMYK inks, additional colors have been included in some printers which can be now known as 6 color digital printers, having added a mild cyan as well as a light magenta to achieve a few of the harder colors to make from the printing process. Some printers have even added orange and green cartridges at the same time.
Dye sublimation printing is slightly different. The dyes used are similar to ink, although with some differences. The ink looking for dye sub printing can be another four color process (commonly known in shorthand as 4CP), nevertheless the shorthand version here is CMYO, or cyan-magenta-yellow-overprint clear. Where will be the black, you may wonder? It could be hard to create a full color spectrum without black!
To describe where black went, or rather more accurately, where it appears from in CMYO dye sublimation printing, I need to explore the rest of the way it operates. As stated previously, a standard 4CP computer printer is necessary to print dyes too, but the dye has to be printed with a treated paper cleverly named “transfer paper.”
A graphic is printed in reverse (or mirror printed) around the neon sublimation ink. The paper is matched up to and including part of fabric. The material should not be an all natural fiber as a result of process that will be explained momentarily. The fabric typically used usually is polyester as it is a versatile fiber that may be intended to appear to be anything from an oil canvas to a sheer fabric into a double-sided knit material which can be made in to a double-sided flag or banner.
As soon as the paper is matched towards the fabric, it can be run through heated rollers at high pressure. The rollers are heated just to under 400 degrees Fahrenheit or 210 degrees Celsius. Since the fabric experiences the heated rollers, 2 things happen. First, the pores or cells of the poly-fabric open, while simultaneously the dye around 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 cannot be achieved utilizing an computer printer as a result of dot pattern laid down through the inkjets.
If an item like plastic or aluminum is coated having a special polymeric coating, these products 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 for example T-shirts, table covers, sportswear, ID cards, and signs.
Some benefits of heat transfer vinyl roll is the image is a part of the fabric, so it doesn’t remove like ink on top of fabric or other materials and will not fade for several years. The dye cannot increase on fabric like t-shirts either. Everyone had worn a printed shirt the location where the ink felt like it was very stiff on the surface of the material, and also over time that it will begin to flake off. This may not occur with dye sublimation.
Other advantages are that this colors might be more brilliant than other kinds of printing because of the procedure for dye sublimation and also the continuous tones which can be achieved as soon as the dye converts to your gaseous state. Because in printing garments the fabric is printed just before the shirt or jacket is constructed, the photo can proceed to the fringe of the material which happens to be not achievable typically with screen printed shirts.
