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.
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.
At the top of the PDF, click the File option, then click Print, and then click the Advanced button at the bottom of the window. Click the box next to "Print as an Image" to display a check mark, click the "OK" button to close the Advanced Options window, and then click the "OK" button to start printing the document.
For web graphics, especially logos, illustrations, and graphs, PNG images are ideal. If images are edited and saved multiple times, PNG is also a top choice. For printing, PDF images are ideal, particularly for graphic design, posters, and flyers.
In 2 color printing, instead of one on lower end marketing materials, two ink colors are used, vs. four on higher-end commercially printed pieces. Typically, the inks used are Pantone ® colors, and are frequently used in a unique color to print a logo, design or symbol.
Red, magenta and yellow inks are used to make them, as magenta absorbs green light and yellow absorbs blue light, which reflects only red light back to our eyes. You will probably understand the basic mechanism of color printing if you've ever used different colors of paint on a palette.
Prints have a straight edge that is clean, often created by the plate used to create the work. One of the best ways to spot a print is to look at the surface of a painting with a magnifying glass. A high-quality cell phone can often take photos that reveal a great deal, particularly when using various "filters."
