Digital is a printing method that transfers digitized text and images from the computer directly to paper or any other substrate via various types of printing devices, most commonly using a laser or LED to affix toner. Ink jet also falls under this definition but now has its own subcategory. Note that this category is focused exclusively on digital printing. Sites about digital creation of printing films or plates do not belong here. Sites placed in this category should deal primarily with the digital printing process. This includes sites of trade associations, companies selling equipment and supplies, and any site providing resources about the process. In contrast, the sites of printing companies that use this process are not listed here; instead, each printing company is listed in a category based on the type of product it produces. Note: This category is currently undergoing revision, as sites related to a specific products or to general commercial printing are being moved to more appropriate categories elsewhere.

Flexographic printing is a printing technology deriving its name from the use of flexible plates. It is a method of direct (as opposed to offset) printing that uses resilient relief image plates of rubber or photopolymer material and fast drying water-based or UV inks. It is frequently used for printing newspapers, self-adhesive labels, flexible packaging, corrugated containers (boxes), and plastic bags.

Offset Lithography is a printing technique that places ink and water on a chemically treated printing plate. The ink is attracted to the image area and the water is attracted to the non-image area. The inked image is then transferred to a rubber blanket and finally to the paper.

Sheetfed offset presses print on paper that has been cut into individual sheets prior to printing. Web offset presses print from rolls of paper, and any cutting is done after the printing.

This process is frequently used to print publications, catalogs, newspaper supplements, labels, boxes, direct mail pieces, and for other commercial applications.

Pad Printing, also called transfer pad printing, is an indirect offset gravure process characterized by a silicone rubber transfer pad that transfers the image from a printing plate on which the image is etched below the surface of the plate. It is commonly used to print 3D objects with irregular surfaces, such as golf balls.

Rotogravure is the modern adaptation of the gravure process, and uses a rotary press with a copper cylinder. On the cylinder, the image to be printed is cut or etched below the surface of the non-image area in the form of thousands of tiny cells that hold the ink. This process is frequently used to print publications, catalogs, newspaper supplements, labels, cartons, wall and floor coverings, packaging, and gift-wrap.

Thermography, also known as raised printing, involves applying a powder to paper with wet ink on it, and then heating the paper to make the powder adhere. Popular uses include business stationery, presentation folders, annual report covers, announcements, greeting cards, packaging, wrapping paper, and point of purchase displays.
