Printing Types

Serigraph Printing

Serigraphy is a printing technique in which the ink is forced through to be transfered onto the layer beneath except the zones turned out to be ink-impermeable by a blockage screen. Serigraphy printing is also a screen method in which empty areas are streched over a polyester or other finely woven frame coated with impermeable material and design is applied on. Ink is forced by a filling knife or squeegee into the net openings and wetted and transfered onto the printing surface during the squeegee decline. In fact there are various terms used for the same technique. This procedure was named as serigraphy or silk printing traditionally because silk was used before finding out polyester texture usage in the process. Synthetical textures are commonly used in frame printing today. In general common usage the most popular net is made of polyester. In this technique developed by the Chinese and of which the roots’ origin started 2000 years ago, fabrics made of human hair were used first. It is a recognizable moulding technique seen in a China. Later on silk weaving is developed in Japan. It used to be applied and adapted by other Asian countries such as in Japan and improved by adding newer methods. Today, chemically very resistant fibre polyester is more common due to its durability and economy. Serigraph printing method is used on many products you see everyday.


Pad Printing (Tampography)

Pad printing is a sort of printing in which paint is transfered to printing area via silicone. Serigraph printing is the technique that enables printing on all flat, curved, crumpled surfaces such as golf ball, lighter or pen size products that silk can not reach in high definition. Pad printing is used on almost all products we use in our daily lives and there is almost no product (substrate) on which pad printing can not be done. The key elements of pad printing process are the pad, the cliché, and the ink. Each of these elements are explained in greater detail in subsequent articles. Together, these three elements allow more ­exibility in the types of products that can be printed using this process than any other printing process. The first pad printing was done using gelatin material to transfer the image. The origins of pad printing can be traced back more than 200 years ago.

 

UV Printing

UV (ultraviolet) light is a part of electromagnetic spectrum. UV printing technique with the aim of limiting time of curing in print works due to its durability against sun radiation reduces the drying time of the inks by far less than 1 second, thus eliminating the sun or the environment from influencing the printing color because of the paint specifications as well, providing sunfasting and so avoids these and similar causes of damages to printing. The substrates formed with UV Printing system are not effected from materials like water and also are more reliable than the ones formed with offset printing. UV inks, being used for more than 20 years in printing industry commonly, become widespread day by day. The water based or solvent based inks used in other printing technologies contain water or solvent that has to evaporate during the drying process after printing. For most of the substrates such as plexiglass, forex, photo block, PVC, wood and similar hard materials, it is possible to print on using UV inks.

 

Laser Printing

Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a “drum” in order to define a differentiated image. The drum then collects electrically charged powdered ink and transfers the image to paper, which is then heated in order to permanently fuse the text or imagery. As with digital photocopiers, laser printers employ a xerographic printing process. However, laser printing differs from analog photocopiers in that the image is produced by the direct scanning of the medium across the printer's photoreceptor, this enables laser printing to copy images more quickly than most photocopiers. Invented at Xerox PARC in the 1970s, laser printers were introduced for the office and then home markets in subsequent years by IBM, Canon, Xerox, Apple, Hewlett-Packard and many others. Over the decades, quality and speed have increased as price has fallen, and the once cutting-edge printing devices are now ubiquitous.

 

Embossing (Engraving) Printing

It is a letter-pressing technique and the term for the process of pushing out the page giving it the raised effect on requested parts of a paper. You can add dimension to the parts on printed or unprinted fields on paper by embossing. Well designed embossing applications look preciously elegant. Besides the value added visually it also stimulates the wish to touch the paper thus enables the printworks to be more memorable. When applied on the area you want to catch attention, it offers a 3D view. Many packages of products, books, agendas, notebook covers and bussiness cards today gain a more valuable and gorgeous view being visually memorable with this method. Embossing process can be applied together with fire gilding upon request to form an estetic view.
