Organic Dyeing Process

Of ink jet printing process nature

Inkjet printing (Ink-jetPrinting) is the printing industry are currently a topic of concern, it is a kind of digital printing, data storage using digital images, you can not arbitrarily change the output before the contents of its output, so it high speed, can be a small amount of copy, easy to mix, to achieve variable information printing, low pollution and so on. In the print format inkjet printing, ink and printing media diversity and so expand the traditional print content, has formed a digital inkjet printing, digital proofing, digital Inkjet Markets.

Ink jet printing is a non-contact, no pressure, no printing plate technology, the development of the earliest in 1878, to the Siemens company in 1951 liquid Ink Into drops of technology patents, was because the needles, ink problems, results are poor, until 1960 formally step. As technology continues to evolve and progress, the growing market, according to the U.S. ITStrategies predicts that by 2009, the global ink-jet market (including hardware, ink jet printing media and ink) of the revenue will total more than 57 billion U.S. dollars.

Color ink-jet printing performance with high picture quality, make most consumers have been satisfied, but the printing time is still too slow, and very high demands on the paper, although the market has a lot of ink in special paper, but the prices are high, it is difficult for the average family and the student population in general use, so let inkjet technology can be widely applicable to various kinds of paper, is now the most urgent need to develop the technology, if special materials to make special Parity of the paper is not easy, so the ink composition is the development of new direct and effective way.

Ink-jet printing ink, special ink is moderate viscosity, a non-toxic, stable, not to plug the nozzle, moisture, spray with good, to the nozzle does not corrode metal components and other properties. Present dye-based ink jet ink to the majority, the ink jet printer must have enough surface tension to prevent the emission of sputtered out when the ink. Another must have Quick-drying ink to prevent the halo on the paper open, therefore, the ink itself is one of the factors affecting the printing quality. The selection of suitable printing ink, regulate the printing parameters, print materials can be satisfied.

An ink-jet ink composition, species Ink jet printing is a very critical component of the development of inkjet ink a certain extent, explains the development of inkjet printing technology, because not only determines the ink jet image quality, but also determines the shape of drops and printing system reliability. Inkjet ink is generally from the colors, link material and additives. Printing ink material may be water, oily substances, Solvent , Resin, which determines the dynamic properties of the ink distribution; the inkjet ink, the link to feed 40% -90%. Pigment in the ink color in the main role plays, usually 1% -10%. The rest are called additive, mainly used to improve the ink’s viscosity, adhesion strength, thermal stability, light resistance and surface tension.

Overall, the inkjet printing process used in more types of ink, classification more. It is generally shown from the ink to classify the different aspects of nature, is generally based on different binders to ink into water-based ink, oil-based ink, solvent-based inks and heatset ink.

1. Water-based ink Commonly used in perforated and non-coated printing materials such as cardboard and paper products are often used for direct mail printing and other commercial printing market, the most commonly used. Can be classified as pigment and dye based, pigment because they do not dissolve in water, will precipitate, so a very small pigment particles to be worn, to small to 30 m below, will have good printing effect, or when using high-resolution easily cause obstruction. Paint their weather resistance, lightfastness, washing fastness, wear fastness are very good. The advantage is that the solubility of dye without problems and so many types of color, brightness and good, but poor color fastness.

2. The most suitable oil-based ink on the printed material in the hole, as it is to be dry by absorbing their recipe vegetable oil or mineral oil, which in cardboard packaging applications especially; not suitable in a confined office space, as it will cause pollution. Pigment used in paint type and the dye can be divided into two kinds, oil-soluble inks are characterized by fast drying, so commonly used in industry.

3. More extensive use of solvent-based ink from printing to bar code label printing to Outdoor advertising The use of this ink, high cost, fast-drying, can be printed in a variety of materials, especially for the printing of non-coated material such as vinyl, wire, glass and paper.

4.UV/EB thermosetting ink in the ink for printing in a variety of flexible and rigid printed materials such as corrugated cardboard and metal foil, UV / EB ink curing under UV light, faster, more durable strong. Very suitable for DOD applications, such as retail point of display advertising, phone cards, credit cards and frequent use of the shopping card.

Addition to the binders for the distinction to be separation, in practice, several other classification methods: by pigment to sub-divided into organic dye-based inks, polymeric dye-based ink and pigment-based inks; if under ink used in different Dryer Management, can be volatile inks and ink into polymer-based ink. Water-based and non-aqueous ink is water or other solvent as the link material, the dried ink from the substrate on the penetration and absorption to complete, if you use regular copy paper or a tablet of paper, ink and substrate along with links to material absorption This will reduce the absorption of the color density and print sharpness. Heatset ink is ink that is solid at room temperature, when the nozzle is hot melt liquid, the substrate surface to reach a rapid solidification, rapid solidification characteristics of this ink to prevent proliferation or infiltration to the substrates within to ensure the printing quality.

Best restorative hair care?

I recently colored my hair, which was a last minute decision. My hair stylist recommended I use a restorative mask or a shampoo & conditioner. I am looking for one that is gentle. What are your recommendations?

I would make a hair mask at home, that way you can control the ingredients. Use about half an avocado, smash it until is smooth, then mix in a teaspoon or two of olive oil. Put it on your dry hair, starting at the roots, cover your hair with a shower cap, and then relax for 15-20 minutes. Maybe you could put a drop of tea tree oil in the mask, too, if your doctor recommended the Tea Tree shampoo. You said your skin is pretty sensitive, so I wouldn’t use too much of the tea tree oil, but maybe it will help.

I don’t have any suggestions for the shampoo and conditioner, sorry! I use Biolage for color treated hair, but I think it may have the sulfate you want to avoid.
