Question: Can you please describe how dye sublimation printing works? Which kind of printer can be used? Will it be just like heat transfer printing?
Answer: Wow! All very good and related questions to the dye sub as well as heat transfer printing of fabric, one of the most popular ways to print fabric and also other items, even if this answer will deal mostly with polyester fabric.
First, the two main kinds of transfer paper. One uses ribbon so transfer color into a transfer paper, and the other is the same basic printing method as digital printing except there are actually differences between ink and dye. As well as the same printers works extremely well, although not interchangeably as a result of differences between dyes and ink.
Inkjet printing uses, typically, what is known as the “four color process” printing method. The four colors are also known in shorthand as CMYK ink colors. CMYK means Cyan-Magenta, Yellow, and Black, which in almost any combination will print virtually any color, excluding neon colors or metallic colors, but the majority colors in the photo spectrum.
Due to limitations of CMYK inks, additional colors have already been included in some printers that are now referred to as 6 color digital printers, having added a light cyan plus a light magenta to achieve several of the harder colors to make within the printing process. Some printers have even added orange and green cartridges also.
Dye sublimation printing is slightly different. The dyes used act like ink, though with some differences. The ink looking for dye sub printing can be another four color process (also known in shorthand as 4CP), however the shorthand version here is CMYO, or cyan-magenta-yellow-overprint clear. Where may be the black, you could wonder? It could be hard to create a full color spectrum without black!
To clarify where the black went, or rather more accurately, where it comes from in CMYO dye sublimation printing, I have to explore most of how it works. As stated previously, a typical 4CP printing device is required to print dyes at the same time, nevertheless the dye should be printed on the treated paper cleverly named “transfer paper.”
A graphic is printed in reverse (or mirror printed) around the sublimation ink. The paper is matched to a bit of fabric. The fabric should not be an all-natural fiber because of the process that might be explained momentarily. The fabric typically used more often than not is polyester since it is an adaptable fiber that can be created to appear to be anything from an oil canvas into a sheer fabric into a double-sided knit material that can be made right into a double-sided flag or banner.
After the paper is matched to the fabric, it is actually run through heated rollers at high pressure. The rollers are heated just to under 400 degrees Fahrenheit or 210 degrees Celsius. As the fabric passes through the heated rollers, a couple of things happen. First, the pores or cells in 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 while they leave the heated rollers. This produces a continuous tone print which cannot be achieved utilizing an inkjet printer because of the dot pattern laid down with the inkjets.
If an item including plastic or aluminum is coated having a special polymeric coating, these products can 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 for example T-shirts, table covers, sportswear, ID cards, and signs.
Some benefits to heat transfer vinyl is the fact that image is an element of the fabric, so it doesn’t peel off like ink on the surface of fabric or some other materials and definately will not fade for a long time. The dye cannot increase on fabric like t-shirts either. Everyone had worn a printed shirt in which the ink felt enjoy it was very stiff at first glance in the material, and over time it will quickly flake off. This may 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 which are achieved once the dye converts into a gaseous state. Because in printing garments the fabric is printed prior to the shirt or jacket is constructed, the graphic can go to the edge of the material that is not achievable typically with screen printed shirts.
