Question: Could you please describe how dye sublimation printing works? What kind of printer is commonly used? Is it similar to heat transfer printing?
Answer: Wow! All very good and related questions to the dye sub and also heat transfer printing of fabric, one of the best strategies to print fabric as well as other items, although this answer will deal mostly with polyester fabric.
First, there are 2 varieties of heat transfer paper. One uses ribbon so transfer color to some transfer paper, as well as the other is the same basic printing method as digital printing except there are differences between ink and dye. And also the same printers works extremely well, although not interchangeably because of the 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 means Cyan-Magenta, Yellow, and Black, which in any combination will print just about 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 are already included in some printers that are now generally known as 6 color digital printers, having added an easy cyan and a light magenta to reach a few of the harder colors to make within 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, but with some differences. The ink looking for dye sub printing can be another four color process (commonly known in shorthand as 4CP), but the shorthand version is CMYO, or cyan-magenta-yellow-overprint clear. Where is definitely the black, you may wonder? It could be hard to make a full color spectrum without black!
To describe 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 works. As mentioned previously, an ordinary 4CP laser 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) in the kiian sublimation ink. The paper is matched as much as a part of fabric. The fabric should not be an organic fiber because of the process that can be explained momentarily. The material typically used usually is polyester because it is an adaptable fiber which can be intended to look like everything from an oil canvas to your sheer fabric to your double-sided knit material that may be made in to a double-sided flag or banner.
After the paper is matched on the fabric, it is 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 in the poly-fabric open, 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 produces a continuous tone print which should not be achieved using an laser printer due to the dot pattern laid down by the inkjets.
If the item such as plastic or aluminum is coated having a special polymeric coating, these things can be printed. Besides banners and posters and flags, other items that happen to be 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 would be that the image is an element of the fabric, so that it doesn’t remove like ink on top of fabric or another materials and can 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 want it was very stiff on top of the material, and over time that it will flake off. This can not happen with dye sublimation.
Other advantages are that the colors could be more brilliant than other printing due to the process of dye sublimation along with the continuous tones that happen to be achieved if the dye converts to some gaseous state. Because in printing garments the fabric is printed prior to the shirt or jacket is constructed, the photo can go to the fringe of the material which happens to be not achievable typically with screen printed shirts.
