Question: Could you please describe how dye sublimation printing works? What kind of printer is utilized? Could it be the same as heat transfer printing?
Answer: Wow! All great and related questions to the dye sub as well as heat transfer printing of fabric, one of my favorite methods to print fabric along with other items, although this answer will deal mostly with polyester fabric.
First, the two main kinds of sublimation transfer paper. One uses ribbon so transfer color to a transfer paper, as well as the other is the same basic printing method as digital printing except you can find differences between ink and dye. And the same printers may be used, 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 4 colors are also known in shorthand as CMYK ink colors. CMYK is short for Cyan-Magenta, Yellow, and Black, which in every combination will print just about any color, not including neon colors or metallic colors, but many colors from the photo spectrum.
Because of the limitations of CMYK inks, additional colors happen to be added to some printers that are now referred to as 6 color digital printers, having added a light cyan plus a light magenta to arrive at a few of the harder colors to create in the printing process. Some printers have even added orange and green cartridges too.
Dye sublimation printing is slightly different. The dyes used act like ink, however with some differences. The ink looking for dye sub printing is another four color process (best known in shorthand as 4CP), however the shorthand version the following is CMYO, or cyan-magenta-yellow-overprint clear. Where is the black, you may wonder? It would be hard to generate a full color spectrum without black!
To spell out in which the black went, or rather more accurately, where it will come from in CMYO dye sublimation printing, I have to explore most of the way it works. Mentioned previously previously, a regular 4CP printing device is necessary to print dyes as well, although the dye needs to be printed over a treated paper cleverly named “transfer paper.”
An image is printed in reverse (or mirror printed) on the kiian sublimation ink. The paper is matched up to and including part of fabric. The fabric cannot be an all natural fiber due to the process that can be explained momentarily. The material typically used quite often is polyester because it is an adaptable fiber that could be intended to appear to be anything from an oil canvas to some sheer fabric to a double-sided knit material that could be made in a double-sided flag or banner.
As soon as the paper is matched towards the fabric, it is actually run through heated rollers at high-pressure. The rollers are heated to just under 400 degrees Fahrenheit or 210 degrees Celsius. Since the fabric experiences the heated rollers, two things happen. First, the pores or cells in the poly-fabric open up, while simultaneously the dye on the paper is transformed into a gaseous state. The gas impregnates the open cells which close while they leave the heated rollers. This generates a continuous tone print which can not be achieved using an inkjet printer because of the dot pattern laid down by the inkjets.
If the item for example plastic or aluminum is coated with a special polymeric coating, these things can even be printed. Besides banners and posters and flags, other items 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 film is that the image is an element of the fabric, therefore it doesn’t peel off like ink at first glance of fabric or another materials and definately will not fade for several years. The dye cannot build-up on fabric like t-shirts either. Everyone had worn a printed shirt in which the ink felt enjoy it was very stiff on the surface in the material, and also over time that it will start to flake off. This may not happen with dye sublimation.
Other advantages are that this colors might be more brilliant than other kinds of printing as a result of procedure of dye sublimation as well as the continuous tones that happen to be achieved when the dye converts to a gaseous state. Because in printing garments the material is printed before the shirt or jacket is constructed, the image can visit the side of the fabric which can be not achievable typically with screen printed shirts.
