Question: Are you able to please describe how dye sublimation printing works? What kind of printer can be used? Could it be just like heat transfer printing?
Answer: Wow! All really good and related inquiries to the dye sub and heat transfer printing of fabric, certainly one of my favorite strategies to print fabric and other items, although this answer will deal mostly with polyester fabric.
First, the two main types of heat transfer paper. One uses ribbon so transfer color into a transfer paper, and also the other is the same basic printing method as digital printing except there are actually differences between ink and dye. Along with the same printers works extremely well, however, not interchangeably due to differences between dyes and ink.
Inkjet printing uses, typically, what is known the “four color process” printing method. The 4 colors will also be known in shorthand as CMYK ink colors. CMYK is short for Cyan-Magenta, Yellow, and Black, which in any combination will print virtually any color, not including neon colors or metallic colors, but a majority of colors within the photo spectrum.
Due to the limitations of CMYK inks, additional colors have already been included with some printers which are now known as 6 color digital printers, having added a mild cyan and a light magenta to attain several 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 act like ink, although with some differences. The ink looking for dye sub printing is another four color process (also known in shorthand as 4CP), nevertheless the shorthand version the following is CMYO, or cyan-magenta-yellow-overprint clear. Where may be the black, you might wonder? It would be hard to generate a full color spectrum without black!
To describe the location where the black went, or rather better, where it will come from in CMYO dye sublimation printing, I have to look into the rest of how it works. As stated previously, a regular 4CP laser printer is needed to print dyes at the same time, however the dye must be printed over a treated paper cleverly named “transfer paper.”
An image is printed in reverse (or mirror printed) about the ink sublimation. The paper is matched up to and including piece of fabric. The material should not be an all-natural fiber because of the process which will be explained momentarily. The fabric typically used usually is polyester since it is an adaptable fiber that may be designed to seem like everything from an oil canvas to a sheer fabric into a double-sided knit material which can be made in a double-sided flag or banner.
When the paper is matched towards the fabric, it can be run through heated rollers at high pressure. The rollers are heated to just under 400 degrees Fahrenheit or 210 degrees Celsius. As being the fabric passes through the heated rollers, a couple of things happen. First, the pores or cells of the poly-fabric start, while simultaneously the dye about the paper is converted to a gaseous state. The gas impregnates the open cells which close as they leave the heated rollers. This generates a continuous tone print which can not be achieved employing an laser printer because of the dot pattern laid down by the inkjets.
If an item including plastic or aluminum is coated using a special polymeric coating, these items may also be printed. Besides banners and posters and flags, other items which are commonly dexupky33 with dye sublimation heat transfer printing are clothing items for example T-shirts, table covers, sportswear, ID cards, and signs.
Some advantages to heat transfer film would be that the image is a part of the fabric, thus it doesn’t remove like ink at first glance of fabric or another materials and definately will not fade for quite some time. The dye cannot build-up on fabric like t-shirts either. Everyone had worn a printed shirt where ink felt enjoy it was very stiff on the outside of the material, and over time that it will start to flake off. This will not occur with dye sublimation.
Other advantages are that the colors might be more brilliant than other printing because of the process of dye sublimation as well as the continuous tones that happen to be achieved when the dye converts to your gaseous state. Because in printing garments the material is printed ahead of the shirt or jacket is constructed, the photo can check out the fringe of the material which can be not achievable typically with screen printed shirts.
