Process printing plates are used to print "process color" jobs--ones that use cyan, magenta, yellow and black inks.

Printing processes such as offset printing use printing plates to transfer an image to paper or other substrates. The plates may be made of metal, plastic, rubber, paper, and other materials. The image is put on the printing plates using photomechanical, photochemical, or laser engraving processes. The image may be positive or negative. http://www.ezeeprinting.com/page/pulpboard-coasters

There are typically two types of wipe-on plates used in offset printing: polyester-based plates and aluminum-based plates. Polyester-based plates are often used for shorter print runs and quick turnaround times, while aluminum-based plates are preferred for longer print runs and higher quality printing. Both plate types require wiping or cleaning with a damp sponge before printing to remove any residual ink.
Offset printing plates are typically made of either aluminum or polyester. Aluminum plates are more commonly used for higher quality printing jobs, as they are more durable and provide better ink adhesion. Polyester plates are generally used for shorter print runs or simpler print jobs.
There is a 3 step process in order to begin flexographic printing which are making the colored plates required to print, mounting the plates made in the first step, and the final printing stage. Flexographic printing is commonly used when printing on non-porous surfaces like food wrappers.

Consistent high image quality.Offset printing produces sharp and clean images and type more easily than letterpress printing because the rubber blanket conforms to the texture of the printing surface.Quick and easy production of printing plates.Longer printing plate life than on direct litho presses because there is no direct contact between the plate and the printing surface.Properly developed plates running in conjunction with optimized inks and fountain solution may exceed run lengths of a million impressions.Cost. Offset printing is the cheapest method to produce high quality printing in commercial printing quantities.Disadvantages of offset printing compared to other printing methods include:Slightly inferior image quality compared to rotogravure or photogravure printing.Propensity for anodized aluminum printing plates to become sensitive (due to chemical oxidation) and print in non-image/background areas when developed plates are not cared for properly.Time and cost associated with producing plates and printing press setup. This makes smaller quantity printing jobs impractical. As a result, smaller printing jobs are now moving to digital offset machines.
Offset printing requires the creation of printing plates and uses ink transferred from plates to a rubber blanket, then onto paper. On the other hand, digital printing involves direct transfer of digital files onto paper without the need for plates, making it more suitable for smaller print runs and customization. These processes vary in setup costs, speed, and flexibility.
The traditional printing press systems (Lithography, flexography, gravure etc.) use printing plates that 'press' the ink onto the pages. Digital printing presses operate frequently today as a replacement to the old technology because they don't require the physical printing plates to be designed for each page, so it can all be done digitally - saving time and money.

A person who creates plates is often referred to as a potter, particularly if they work with clay and ceramics. In the context of printing, a person who creates printing plates is called a plate maker. Additionally, in the culinary world, a chef or food stylist might be involved in creating aesthetically pleasing plate presentations.
