4 Colour process - CMYK
Also possible to use spot colours
Printing process through which the inked image from a printing plate is transferred or offset to a rubber blanket roller, which is then pressed against the substrate. When the plate passes under the ink roller, non-image areas that have a water film repel the oily inks that stick to the image areas.
Used for - Flyers, Brochures & Magazines
Disadvantages - Only available for long print runs to justify the hours of setting up machines and plates. For long print runs image quality can deteriorate due to wear on the plate.
4 Colour Process - CMYK
Also possible to use spot colours
The image is engraved onto a cylinder because it uses a rotary printing press. An indirect image carries such as gravure cylinders, the ink is applied directly to the cylinder and from the cylinder it is transferred to the substrate. It uses copper plates
Used for - Magazines, postcards and corrugated (cardboard) product packaging
Web
Uses stock that is supplied on massive rolls rather than individual sheets which allows for higher volume printing speeds and a lower production cost. Webs can be used with lithography, but more commonly with relief printing methods such as rotogravure and flexography as their plates are more durable.
Used for - Newspapers, catalogues, magazines and books
Disadvantages - Due to the scale and cost of the production it isn't suitable for low-volume print runs.
4 Colour Process CMYK with spot colours available
The printed image is achieved by means of a soft, flexible plate which contains the image to be printed in relief, much like a rubber stamp. The plate is attached to the roller (cylinder) and placed on the press.
Used for - Food Packaging (wrappers), labels, adhesive tapes, envelopes, newspapers, plastic bags, milk and beverage cartons etc
Disadvantages - Not the best print quality but because its used for disposable packaging its not much of an issue.
Printing process that can transfer a 2-D image onto a 3D object. Using an indirect offset (gravure) process, the image is transferred from the printing plate via a silicone pad onto the substrate.
Used for - Medical packaging, Automotive, promotional, apparel, electronics, appliances, sports equipment and a large majority of 3D objects.
Relatively low volume printing method in which inks are passed through an exposed image on a screen. Although its a slow and expensive printing method it allows printing onto a large variety of sources. The viscous inks allow specific colours to be applied and can also be used to create a raised surface that adds a tactile element to a design.
Disadvantages - Time Consuming, expensive
Digital
Inkjet or laser printers deposit pigment or toner onto a variety of substrates. Because it doesn't use plates and can be printed directly from a computer it saves a lot of money but isn't suitable for longer print jobs because of the high costs for Toners and inks.
Used for - Printing onto paper, photo paper, canvas, glass, metal
Disadvantages - Expensive inks and toners, not suitable for long print runs
A method of relief printing whereby inked, raised surface is pressed against a substrate. The raised surface that is inked may be made from single type blocks, cast lines or engraved plates. Letter press has a unique and beautiful aesthetic.
Disadvantages - Time consuming process that takes years of practice to master, suitable for low volume print
