Matt Theobald has been working in the [url=http://www.getconversational.com]hollister pas cher[/url] exhibition and display industry for over 20 years. Having been involved in the design and build of exhibition stands throughout Europe and having specialised for a number of years in large-format digital print he has a [url=http://www.sandvikfw.net/shopuk.php]hollister outlet sale[/url] wealth of experience in this arena.
Types of Ink.
There are three [url=http://www.davidhabchy.com]barbour sale[/url] main types of ink used in inkjet printers: Solvent, water, and oil based.
Water-based inks: Water-based or Aqueous/thermal inks are divided into two categories, Pigmented Inks and Dye inks.
Dye inks are formulated with the tiny molecules carrying the colour property suspended in a water-based carrier solution. They have a high colour brilliance and a wide gamut of colour. However the ability to resist light isn�t good and they are [url=http://www.davidhabchy.com]barbour outlet[/url] subject to damage by water once printed onto the substrate. Because the colour is held in [url=http://www.jordanpascherofficiel.com]air jordan pas cher[/url] solution the size of the colour carrying element is minute and therefore is more tolerant of the make up of the paper it is being printed onto and also tends to dry faster.
Pigmented Inks.
Particles of pigment are held in suspension in a water-based carrier liquid. They [url=http://www.achbanker.com/home.php]hollister france[/url] are much larger than the the molecular-sized colour in dye-based inks. They are much more fade resistant and can have a limited outdoor application as they are not adversely affected by water once they have dried. Because of their heavier structure, they need a more porous or specially coated media in order to [url=http://www.rtnagel.com/louboutin.php]louboutin pas cher[/url] dry.
Solvent-based Inks.
Inks in [url=http://www.rtnagel.com/airjordan.php]jordan pas cher[/url] this category can be broken down into 2 groups that are referred to in a number of different ways including: soft, mild, safe, eco, and green as well as hard, real, true, and strong. [url=http://www.americatownmovie.com]air jordan pas cher[/url] The term �eco� is often used to suggest that the product is [url=http://www.jordanpascherofficiel.com]air jordan[/url] ecologically safe, however they contain chemicals derived from mineral oil which are neither renewable or easily disposed of in a non-damaging way. The main difference between the 2 groups is that one type is aggressive and produces good results on a wider range of un-coated medias while the mild solvents may need a coated media or an over-laminate in order to give similar performance.
Both types of solvent ink uses a fine powder pigment which is dissolved into a solvent carrier fluid combined with a resin or glue. Once the [url=http://www.thehygienerevolution.com/barbour.php]barbour paris[/url] droplet of ink is sprayed onto the substrate the solvent evaporates leaving the pigment to stick to the surface with resin.
The Solvent inks are delivered onto the substrate using Piezo printhead technology that ensures an accurate and fast print.
Unlike water based inks where the substrate [url=http://www.thehygienerevolution.com/barbour.php]barbour[/url] needs to be coated with an ink-receptive layer the solvent process can produce prints suitable for exterior use on non-absorbent, uncoated materials such as self-adhesive vinyl and scrim banner fabrics, pvc and polyester.
The resultant print is weatherproof and fade-proof and, to a certain extent, scratch-proof.
The Mild Solvent Inks use slow drying carrier fluids and so printers that utilise this type of ink usually have heaters to dry the ink as it is printed.
Agressive solvents dry faster and have the added benefit of softening the substrate surface creating a stronger bond.
