Question: Can you please describe how dye sublimation printing works? What type of printer is used? Would it be the same as heat transfer printing?
Answer: Wow! All great and related inquiries to the dye sub as well as heat transfer printing of fabric, certainly one of my personal favorite methods to print fabric and other items, even though this answer will deal mostly with polyester fabric.
First, there are two varieties of sublimation 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 you can find differences between ink and dye. Along with the same printers can be utilized, while not interchangeably due to the 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 stands for Cyan-Magenta, Yellow, and Black, which in any combination will print virtually any color, not including neon colors or metallic colors, but many colors in the photo spectrum.
As a result of limitations of CMYK inks, additional colors happen to be included with some printers which can be now referred to as 6 color digital printers, having added an easy cyan and a light magenta to reach some of the harder colors to produce in 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, 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 could possibly wonder? It will be hard to make a full color spectrum without black!
To clarify where the black went, or rather better, where it comes down from in CMYO dye sublimation printing, I have to look into the rest of the way it operates. As mentioned previously, an ordinary 4CP laser printer is needed to print dyes as well, nevertheless the dye must be printed on a treated paper cleverly named “transfer paper.”
A graphic is printed in reverse (or mirror printed) in the kiian sublimation ink. The paper is matched as much as a bit of fabric. The fabric should not be an all natural fiber as a result of process that might be explained momentarily. The material typically used most of the time is polyester since it is an adaptable fiber that may be made to appear to be everything from an oil canvas into a sheer fabric to some double-sided knit material that may be made in to a double-sided flag or banner.
After the paper is matched for the fabric, it can be run through heated rollers at high pressure. The rollers are heated to simply under 400 degrees Fahrenheit or 210 degrees Celsius. As the fabric experiences the heated rollers, 2 things happen. First, the pores or cells from the poly-fabric start, while simultaneously the dye in the paper is changed into a gaseous state. The gas impregnates the open cells which close as they leave the heated rollers. This creates a continuous tone print which cannot be achieved utilizing an printing device due to dot pattern laid down by the inkjets.
If the item for example plastic or aluminum is coated using a special polymeric coating, these products can be printed. Besides banners and posters and flags, other considerations that are commonly dexupky33 with dye sublimation heat transfer printing are clothing items such as T-shirts, table covers, sportswear, ID cards, and signs.
Some benefits to heat transfer vinyl sheets is the fact that image is an element of the fabric, therefore it doesn’t peel off like ink on the surface of fabric or any other materials and definately will not fade for quite some time. The dye cannot develop on fabric like t-shirts either. Everyone had worn a printed shirt where the ink felt want it was very stiff on top of your material, and over time that it will flake off. This can not occur with dye sublimation.
Other advantages are the colors might be more brilliant than other printing due to the procedure for dye sublimation along with the continuous tones that are achieved as soon as the dye converts to some gaseous state. Because in printing garments the fabric is printed before the shirt or jacket is constructed, the photo can check out the fringe of the fabric which is not achievable typically with screen printed shirts.
