Today, average inkjet printers generally have a 1200 x 1440 dpi resolution. If you're not going to print photos larger than 5 x 7 inches, this is a good enough resolution.
Woodblock printing, which appeared in China before 220 AD, was the earliest known form of printing applied to paper. The movable type invented by Bi Sheng around 1040 AD and the printing press invented by Johannes Gutenberg in the 15th century are also later developments in printing technology.
It is called offset because it does not directly transfer the ink to the paper. Because offset presses run so efficiently once set up, when larger quantities are required, offset printing is the best choice and provides accurate color reproduction and crisp , clean, professional-looking printing.
The technique used distinguishes the different types of intaglio prints: etching, aquatint, and photogravure are made using acid to corrode the metal plate, while engraving, drypoint, and mezzotint are made using a sharp tool to incision or scratch the plate 's surface.
Typically, color printing uses four-color inks: cyan , magenta , yellow, and black. The resulting "primary" mixtures are red, green , and blue when the CMY "secondary" is combined at full strength.
The format can easily handle high resolution photos thanks to PNGs' high color depth. Since it is a lossless web format, however, file sizes tend to get very big. For the screen, PNG graphics are optimized. You could definitely print a PNG, but with a JPEG (lossy) or a TIFF file, you'd be better off.
There is no need for online access to operate printers used to output documents from a computer. Provided that the document or file to be printed is stored on a local hard drive or on the local network, it can be printed without an Internet connection.
