Question: Can you please describe how dye sublimation printing works? Which kind of printer can be used? Would it be the same as heat transfer printing?
Answer: Wow! All very good and related questions to the dye sub as well as heat transfer printing of fabric, among my favorite approaches to print fabric as well as other items, although this answer will deal mostly with polyester fabric.
First, the two main varieties of transfer paper. One uses ribbon so transfer color to some transfer paper, along with 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 utilized, however, not interchangeably as a result of 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 almost any combination will print nearly every color, excluding neon colors or metallic colors, but most colors from the photo spectrum.
Due to the limitations of CMYK inks, additional colors happen to be included in some printers which can be now generally known as 6 color digital printers, having added a light cyan along with a light magenta to achieve some of the harder colors to make inside the printing process. Some printers have even added orange and green cartridges also.
Dye sublimation printing is slightly different. The dyes used are exactly like ink, but with some differences. The ink looking for dye sub printing is yet another four color process (best known in shorthand as 4CP), but the shorthand version the following is CMYO, or cyan-magenta-yellow-overprint clear. Where is definitely the black, you could possibly wonder? It would be hard to create a full color spectrum without black!
To spell out where black went, or rather more accurately, where it comes from in CMYO dye sublimation printing, I need to look into the rest of how it works. As mentioned previously, an ordinary 4CP laser printer is needed to print dyes at the same time, although the dye should be printed on a treated paper cleverly named “transfer paper.”
An image is printed in reverse (or mirror printed) around the neon sublimation ink. The paper is matched up to and including part of fabric. The fabric can not be an all natural fiber as a result of process that might be explained momentarily. The fabric typically used quite often is polyester because it is a versatile fiber that can be designed to look like everything from an oil canvas to your sheer fabric to some double-sided knit material that could be made in to a double-sided flag or banner.
After the paper is matched to 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. As the fabric goes through the heated rollers, 2 things happen. First, the pores or cells from the poly-fabric open up, while simultaneously the dye about the paper is changed into a gaseous state. The gas impregnates the open cells which close while they leave the heated rollers. This results in a continuous tone print which can not be achieved having an inkjet printer due to the dot pattern laid down from the inkjets.
If the item like plastic or aluminum is coated having a special polymeric coating, these materials may also be printed. Besides banners and posters and flags, other considerations that happen to be 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 that the image is an element of the fabric, thus it doesn’t remove like ink on the surface of fabric or another materials and will not fade for a long time. The dye cannot increase on fabric like t-shirts either. Everyone had worn a printed shirt in which the ink felt as if it was very stiff at first glance in the material, and also over time it will quickly flake off. This can not occur with dye sublimation.
Other advantages are the colors could be more brilliant than other kinds of printing as a result of process of dye sublimation and also the continuous tones that are achieved as soon as the dye converts into a gaseous state. Because in printing garments the material is printed just before the shirt or jacket is constructed, the graphic can go to the edge of the material which is not achievable typically with screen printed shirts.
