The offset plates are usually aluminum or similar water-friendly metals that are treated with a light-sensitive chemical that attracts oil, When exposed to light with the film overlay or the computer-to-plate (CTP) process and then developed, the image areas attract ink (which is an oil), and the non-printing area repels ink and attracts water. As a form of recess printing, line engraving utilizes incised areas on a printing plate (or base) that hold ink (Figure 5) and, when (usually) moistened paper is pressed against it under intense pressure, the ink is pulled from the recesses. Splashjet has wide array of pigment colorants which offer enhanced print density on uncoated media. Digital printing uses combinations of tiny dots of ink to match specific colors, making it hard to get a perfectly-matched, smooth color.

More on this in a bit. Another evolving technological innovation is the closed-loop color system on offset presses. After the die is finished and approved, it is hardened (tempered) and one or more transfers are taken up on the periphery of a softened steel roll known as a transfer roll (Figure 10).

Digital printing is the process of printing digital-based images directly onto a variety of media substrates. Gravure is gradually losing market share to offset for publication printing and to flexo for packaging applications. But because the plates need replacing after about 1 million-2 million impressions, offset printing requires additional plates for longer runs. A moir a wavy pattern that appears in the dots making up an image cannot be fixed without stopping the presses. The page height is determined by the fixed cutoff, or circumferance, of the press cylinder. For higher volume work offset presses use rolls of paper.

Uncoated and offset-$$- easily available Thanks. The operator also uses this system to start the press by having the computer dial up the correct coverage; the operator can then make minor adjustments to match the color proofs.

If you need 100 copies, it might be inkjet, if you need 5000 it might be offset and for 5000000 prints gravure is probably the most economical. For postage stamps, line engraving begins with a master die (Figure 6) of softened steel (untempered), although copper also can be used for small press runs. Diazo coatings are very thin and susceptible to abrasion and wear during the printing run and generally are used for short press runs of 75,000 impressions or less. The difference between lithograph and print is that lithography is the original artwork of an artist, which is done by oil and water, whereas print is a duplicate copy of documents done by machines.
