Printing methods

With the screen-printing method, films with thicknesses in the region of several tens of micrometers are usually obtained. 

Offset Printing Roll-transfer method of decrating. In most cases less expensive than other multicolor printing methods. Ranges from low-cost hand presses to very expensive automated units. Drying, destaticizers, feeding devices. 

Lettering and decoration can be applied to most materials using various printing methods. Offset printing, silk screening, and pad printing are among the methods adapted to plastics. 

Any forms of contamination at the orifice will lead to the misdirection of the droplets hence, the inkjet printing method requires that the orifice be free of contaminations. Damages at the orifice must be repaired in order to prevent the altering of the size of the...

These dyes have affinity for one or, usually, more types of hydrophobic fibre and they are normally applied by exhaustion from fine aqueous dispersion. Although pure disperse dyes have extremely low solubility in cold water, such dyes nevertheless do dissolve to a limited extent in aqueous surfactant solutions at typical dyeing temperatures. The fibre is believed to sorb dye from this dilute aqueous solution phase, which is continuously replenished by rapid dissolution of particles from suspension. Alternatively, hydrophobic fibres can absorb disperse dyes from the vapour phase. This mechanism is the basis of many continuous dyeing and printing methods of application of these dyes. The requirements and limitations of disperse dyes on cellulose acetate, triacetate, polyester, nylon and other synthetic fibres will be discussed more fully in Chapter 3. Similar products have been employed in the surface coloration of certain thermoplastics, including cellulose acetate, poly(methyl methacrylate) and polystyrene. 

Security printing does not denote a particular printing method but an application sector in which one or several well-known printing methods are used, such as offset, letterpress and gravure printing. 

P.Y.120 lends itself to all printing methods. Its lightfastness in letterpress and offset prints is also very good. Depending on the depth of shade, prints equal step 7 to step 6 on the Blue Scale. P.Y.120 thus scores approximately 1 step higher than the similarly colored P.Y.97. 

The printing ink industry uses P.Br.25 for all printing methods. The prints show excellent lightfastness. 1/1 to 1/25 SD letterpress proof prints, for instance, equal step 7 to step 6-7 on the Blue Scale. Prints made from P.Br.25 are fast to the DIN 16 524 standard solvent mixture, to paraffin, butter, soap, and acid, but they are not entirely fast to alkali. The products are fast to clear lacquer coatings and may safely be sterilized. The temperature stability is up to 240°C for 10 minutes or 220°C for up to 30 minutes, which makes P.Br.25 a suitable candidate for metal deco printing inks. It is also frequently applied in printing inks for PVC.

Jian-hua et al. [137] studied how the MPL sintering temperature and time affected the performance of a fuel cell. It was observed that the best performance was obtained when the MPL was sintered at 350°C for 30 minutes. Lee et al. [138] demonstrated that DLs with an MPL that was screen printed or sprayed performed substantially better than when the MPL was roll coated. In general, the spraying and screen-printing methods are the most widely used.

Inkjet printing as its name implies is a printing method in which a jet of ink is fired, in the form of extremely small droplets, onto a receiving medium. " It is a primary printing technology as the image is printed directly onto the substrate without any intermediate steps. The ink can be supplied in either a continuous manner or inter-...
