Many people are often confused about dye sublimation printing process,they do not understand this process amd what necessities they need during the process.To be short,Dye sublimation is a physical process that involves transforming dye particles from a solid state into a gaseous state, without first turning the solid particles into a liquid. The sublimation of an image from the sublimation transfer paper.onto a substrate involves contact between a printed image on transfer paper with the substrate in the transfer press. The heat in the press causes the dye particles of the images to sublimate. From what we have discussed above, we can find that During the process, the polyester of the substrate is also heated. As a result the molecular chains of the polyester "open'' and the dye particles, in gaseous form, permeate the polyester. On completion of the sublimation prcess, the press is opened and the substrate cools. After cooling, the dyestuff is ''locked up'' in the polyester. The retention of the dyestuff in the polyester demonstrates the high resistance of the dyesubbed images to washing and light exposure compared to decals. The process also works on polyester.cotton blends (at least 65/35, preferably 80/20), some acrylics and nylon 6.6 (for best results consult your dyestuff supplier).
Then ,a new question strick to my mind that what is the definition of digital sublimation transfer printing?Digital sublimation transfer printing echnique as such offers an attractive new alternative decorating method thanks to its relatively low setup cost, the advantages of digital design over screen printing, the elimation of after treatment, as well as its meticulous detail and superior quality.Principles of Digital Transfer Printing ,which can be employed in a variety of applications, including the fashion industry for proofing and short run production, graphic arts, car and furniture upholstering, casino gaming tables, billiards and snooker tables, interior decorating, the soft sign industry for promotional banners, flags.
To make a conclusion based on the above,digital sublimation transfer printing is equipped to meet the challenge of customizing the material would where economical one-offs are possible without compromising quality.
