Sublimation is a fabric printing technique that prints on media using specific inks. It is reserved exclusively for marking textile polyester and hard substrates that are previously treated with varnish industrial polyester.
From an inkjet printer equipped with sublimation inks, the logo is reproduced on a transfer paper. With the help of a hot press under the influence of heat and pressure, the ink penetrates directly in to the mesh of the fabric or polyester, thus coating hard substrates.
Alongside the techniques commonly used in visual communication – such as screen printing or UV laser marking, sublimation printing has grown into a successful technique. Thanks to its many strengths and the very wide range of applications it can be used in. The technique indeed offers new opportunities for professionals who adopt it.
A Simple Concept for Printing on Textile
Using the combined action of heat (180-200 °C for 45 seconds. 10 minutes, depending on application) and pressure, the ink is first sublimated, that is, the ink transforms from its solid state to a gaseous state.The vapors are then impregnated into a support made of polyester or any other material that is previously covered with a layer of polyester (pose spray lacquer clear or white polyester).The treated areas are then printed. According to the production goals of the user or the media type (for example, a firm fabric or stretch), the marking is done directly or indirectly. When the marking is indirect, the process takes place in two steps. Initially, a specific paper is printed by dispersing sublimation inks. Then the paper is put in contact with pre-treated polyester or polyester through for a flat support, hot press or a calendar (roll) and, more recently, for three-dimensional objects in a 3D type sublimation kiln.
Fabric Printing Process Which Respect Environment
This environment-friendly technology uses pigment-based inks and solvent-free water. It does not limit the mark, as the media treated polyester or polyester (textiles, objects) is resistant to heating at 200 °C for 45 secs or 10 minutes depending on the application. It is now applicable to flat shapes (hard or flexible or extensible farms) and 3-D shapes. The impressions and “quad” obtained are always very successful as the support is made of polyester. Other plastics, textiles, ceramics, pottery, glass, wood, iron, aluminum or paper are also used.
Sublimation Printing for Apparel is Affordable
In marking, it offers direct printing of large format visual communications and calculation bases start at $2 per m² ink and $5 to $10 m mesh (standard). These prices are very affordable for professionals. For indirect labeling, it holds more paper at a cost of about $2 per sqm, adding the price of the print line, the grille and oven sublimation 3D. The scope for sublimation printing is very open.
Long Lasting Visual Communication on Fabric
The impression obtained also holds through a special wash to 90 °C. Visual communication technology is becoming increasingly interested in the “big formers “in large format digital printing as it is environmentally friendly and also because the mesh (used with the textile printing process) is easier to transport, set up and allows recycling of the solvent based traditional canvas.This technique is also recommended for communication campaigns of short duration. Communication by the subject and personalization of everyday objects or industries are also other markets in which this technology prints its brands. Replacing other forms of printing with the sublimation process has advantages in terms of cost, quality and laser etching or the placement of adhesive.
Some Advantages of Dye-Sublimation on Textile Include :
- Adaptable from a unit to mass customization
- Perfect rendition of color and brightness
- Reproduction of the images in high definition
- Embedding prints in the fabric using mesh in polyester varnish produces an output without changing the feel of the original product
- Great fit for industrial washing machine at 90 ° C for markings on textiles
- Good resistance in the dishwasher and abrasions to hard substrates
