Question: Are you able to please describe how dye sublimation printing works? Which kind of printer is utilized? Would it be just like heat transfer printing?
Answer: Wow! All great and related inquiries to the dye sub and also heat transfer printing of fabric, among my personal favorite approaches to print fabric and also other items, although this answer will deal mostly with polyester fabric.
First, the two main types of sublimation paper. One uses ribbon so transfer color into a transfer paper, along with the other is identical basic printing method as digital printing except you will find differences between ink and dye. As well as the same printers may be used, 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 may also be known in shorthand as CMYK ink colors. CMYK means Cyan-Magenta, Yellow, and Black, which in virtually any combination will print virtually any color, excluding neon colors or metallic colors, but a majority of colors within the photo spectrum.
Due to the limitations of CMYK inks, additional colors are already added to some printers that happen to be now called 6 color digital printers, having added an easy cyan as well as a light magenta to attain a few of the harder colors to produce inside the printing process. Some printers have even added orange and green cartridges also.
Dye sublimation printing is slightly different. The dyes used are like ink, although with some differences. The ink set for dye sub printing is also a four color process (commonly known in shorthand as 4CP), although the shorthand version is CMYO, or cyan-magenta-yellow-overprint clear. Where may be the black, you may wonder? It will be hard to produce a full color spectrum without black!
To spell out where black went, or rather better, where it comes down from in CMYO dye sublimation printing, I need to explore the remainder of the way it operates. Mentioned previously previously, a typical 4CP laser printer is necessary to print dyes at the same time, although the dye should be printed with a treated paper cleverly named “transfer paper.”
A picture is printed in reverse (or mirror printed) in the dye sublimation ink. The paper is matched up to and including piece of fabric. The fabric should not be an all natural fiber because of the process that can be explained momentarily. The fabric typically used quite often is polyester as it is a flexible fiber which can be made to seem like everything from an oil canvas into a sheer fabric to some double-sided knit material which can be made right into a double-sided flag or banner.
As soon as the paper is matched to the fabric, it is 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 undergoes the heated rollers, 2 things happen. First, the pores or cells of the poly-fabric open up, while simultaneously the dye on the paper is changed into a gaseous state. The gas impregnates the open cells which close since they leave the heated rollers. This creates a continuous tone print which can not be achieved using an printing device because of the dot pattern laid down with the inkjets.
If the item for example plastic or aluminum is coated using a special polymeric coating, these products can 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 such as T-shirts, table covers, sportswear, ID cards, and signs.
Some benefits to heat transfer vinyl would be that the image is a part of the fabric, so it doesn’t peel off like ink at first glance of fabric or other 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 the location where the ink felt enjoy it was very stiff on the surface of the material, as well as over time it will flake off. This may not occur with dye sublimation.
Other advantages are how the colors could be more brilliant than other types of printing due to procedure for dye sublimation along with the continuous tones which are achieved as soon as the dye converts to a gaseous state. Because in printing garments the fabric is printed just before the shirt or jacket is constructed, the image can check out the edge of the material which is not achievable typically with screen printed shirts.
