Question: Can you please describe how dye sublimation printing works? What sort of printer is used? Would it be exactly like heat transfer printing?
Answer: Wow! All great and related inquiries to the dye sub as well as heat transfer printing of fabric, one of my personal favorite strategies to print fabric and also other items, even if this answer will deal mostly with polyester fabric.
First, there are 2 types of sublimation 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 you will find differences between ink and dye. Along with the same printers can be utilized, while not interchangeably because of the 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 stands for Cyan-Magenta, Yellow, and Black, which in any combination will print just about any color, excluding neon colors or metallic colors, but most colors within the photo spectrum.
Due to the limitations of CMYK inks, additional colors have already been added to some printers that happen to be now known as 6 color digital printers, having added an easy cyan along with a light magenta to reach a few of the harder colors to produce in the printing process. Some printers have even added orange and green cartridges as well.
Dye sublimation printing is slightly different. The dyes used act like ink, but with some differences. The ink set for dye sub printing is another four color process (also known in shorthand as 4CP), although the shorthand version here is CMYO, or cyan-magenta-yellow-overprint clear. Where is the black, you might wonder? It might be hard to make a full color spectrum without black!
To describe where black went, or rather better, where it appears from in CMYO dye sublimation printing, I have to explore the remainder of how it operates. Mentioned previously previously, a regular 4CP computer printer is necessary to print dyes also, however the dye must be printed with a treated paper cleverly named “transfer paper.”
A photo is printed in reverse (or mirror printed) in the ink sublimation. The paper is matched up to a component of fabric. The material cannot be an all natural fiber due to process that might be explained momentarily. The fabric typically used most of the time is polyester as it is a flexible fiber that may be designed to appear to be anything from an oil canvas to a sheer fabric to a double-sided knit material that can be made in to a double-sided flag or banner.
When the paper is matched towards the fabric, it really is run through heated rollers at high pressure. The rollers are heated to merely under 400 degrees Fahrenheit or 210 degrees Celsius. As the fabric passes through the heated rollers, two things happen. First, the pores or cells from the poly-fabric unlock, while simultaneously the dye about the paper is converted to 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 utilizing an laser printer as a result of dot pattern laid down with the inkjets.
If an item including plastic or aluminum is coated using a special polymeric coating, these things may also be printed. Besides banners and posters and flags, other considerations that are 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 sheets is that the image is a part of the fabric, so that it doesn’t remove like ink on the outside of fabric or other materials and may not fade for several years. The dye cannot develop on fabric like t-shirts either. Everyone had worn a printed shirt where ink felt want it was very stiff on the outside from the material, as well as over time that it will start to flake off. This will not occur with dye sublimation.
Other advantages are that this colors can be more brilliant than other kinds of printing as a result of process of dye sublimation and the continuous tones that are achieved if the dye converts to some gaseous state. Because in printing garments the fabric is printed just before the shirt or jacket is constructed, the graphic can check out the edge of the fabric which can be not achievable typically with screen printed shirts.
