Printing Methods

To understand printing, one must understand the various printing methods used today to print a product. While there are many different printing methods used today, there are still four main methods: Letterpress Flexography Gravure Offset Lithography Letterpress is the oldest and fastest diminishing method used today. Developed centuries ago by the Chinese it is still […]

Printing Methods – The Printing Press

The printing industry is like a big machine with many gears. For the machine to operate smoothly, all the gears must operate together in harmony. Should one of the gears become out of sync with the others, the machinery stops working!! For example, if the Creative artist is late with the art work, the job […]

Printing Methods – Printing Process Work Flow

OK, so now you know how the market and organization works but how does it all come together? There are three main processes to occur to get the idea to print to the customer: Pre-press – From design to production of the image carrier Press – The process for transferring image to substrate. electronic or […]

Printing Methods – Letterpress

…The oldest form of Printing… Ink is applied to the top surface of the raised image area. This in turn is pressed against the substrate to transfer the image. From the 15 th century until the mid 1940’s, metal type was the only means for converting reading matter into standard type faces for printing. Photographic […]

Printing Methods – Flexography

“Flexo” – A branch of letter press, flexo is a relief process but differs in the composition of the image carrier, ink and the method of ink application. The image carrier may be a molded rubber plate, a photochemically produced photopolymer plastic plate or an image etched into a rubber roller. Low viscosity inks (both […]

Printing Methods – Gravure

Rotogravure is an intaglio process meaning engraved or carved. The impressions are achieved by the transfer of ink from cells or depressions of varying depths, etched into the print cylinder to a web of paper at high speeds. The process of printing involves coating the etched cylinder into an enclosed fountain or trough of ink […]

Printing Methods – Lithography

Lithography… “writing on stone”. Its general meaning is planographic printing, or printing from a plane surface. Lithography is more known by its common name “offset”. Surface chemistry makes the image area water repellent and ink receptive while the non-image areas become water recep-tive and (as long as water is present) ink repellent. The process is […]

Printing Methods – Waterless Offset

There is another form of offset printing which is known as “Waterless Offset”. Waterless offset uses the concept of differential adhesion to keep image and non-image plate areas separate during printing. No fountain solution is used in this process. The method used to achieve this type of printing is a silicone coating on the surface […]

Printing Methods – Common Impression

The common impression (CIS) is a very common type of press used by the Flexo industry. This press is made up of one large impression cylinder with the printing units around it. Each printing unit consists of an Fountain roll, Anilox roll and a plate roll. As the cylinders rotate, the substrate is fed between […]

Printing Methods – Electronic

The indigo E-Print is a combination of the copier and an offset press. The “printing” plate is an photoconductor that receives an image electronically through a computer RIP. The image is then “toned” by a fluid ink, one ink at a time. Six colors are available, the four process colors plus two special spot colors. […]
