Question: Can you please describe how dye sublimation printing works? Which kind of printer can be used? Would it be just 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 the most popular approaches to print fabric and also other items, even though this answer will deal mostly with polyester fabric.
First, there are two kinds of heat transfer paper. One uses ribbon so transfer color to a transfer paper, as well as 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 can be used, while not interchangeably due to differences between dyes and ink.
Inkjet printing uses, typically, what is known as the “four color process” printing method. The four colors will also be known in shorthand as CMYK ink colors. CMYK stands for Cyan-Magenta, Yellow, and Black, which in every combination will print virtually any color, excluding neon colors or metallic colors, but most colors in the photo spectrum.
As a result of limitations of CMYK inks, additional colors happen to be added to some printers that are now referred to as 6 color digital printers, having added a mild cyan as well as a light magenta to arrive at a few of the harder colors to create within 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 are similar to ink, although 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 the following is CMYO, or cyan-magenta-yellow-overprint clear. Where is definitely the black, you could wonder? It might be hard to generate a full color spectrum without black!
To clarify where the black went, or rather better, where it appears from in CMYO dye sublimation printing, I have to look into the remainder of the way it operates. As mentioned previously, a typical 4CP inkjet printer is required to print dyes also, nevertheless the dye must be printed on the treated paper cleverly named “transfer paper.”
An image is printed in reverse (or mirror printed) around the ink sublimation. The paper is matched to a piece of fabric. The material can not be a natural fiber due to process that can be explained momentarily. The fabric typically used more often than not is polyester since it is a flexible fiber that may be made to look like everything from an oil canvas to a sheer fabric to your double-sided knit material that may be made in a double-sided flag or banner.
Once 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 being the fabric goes through the heated rollers, two things happen. First, the pores or cells of the poly-fabric open, while simultaneously the dye around the paper is transformed into a gaseous state. The gas impregnates the open cells which close because they leave the heated rollers. This produces a continuous tone print which cannot be achieved using an computer printer because of the dot pattern laid down by the inkjets.
If an item like plastic or aluminum is coated having a special polymeric coating, these items can also be printed. Besides banners and posters and flags, other things which are commonly dexupky33 with dye sublimation heat transfer printing are clothing items including T-shirts, table covers, sportswear, ID cards, and signs.
Some benefits to heat transfer vinyl is the image is a part of the fabric, so that it doesn’t remove like ink on top of fabric or another materials and will not fade for many years. 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 on the outside of your material, as well as over time that it will begin to flake off. This will likely not occur with dye sublimation.
Other advantages are that the colors could be more brilliant than other sorts of printing because of the technique of dye sublimation along with the continuous tones which can be achieved as soon as the dye converts into a 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 material which can be not achievable typically with screen printed shirts.
