Screen printing, also known as Serigraphy, is a method of creating an image on paper, fabric or some other object by pressing ink through a screen with areas blocked off by a stencil. This technique is used both for making fine art prints and for commercial applications, such as printing a company's logo on coffee mugs or T-shirts.
There is a wide variety of specialty printing techniques available for consumers, who are interested in selling their printed products apart from the ordinary masses. One of the most popular, UV Printing is based on its high impact, affordability, and versatility. Although technically it’s not a “printing” technique, but a coating technique for printed materials, UV coating can be applied to the whole page, or to selected areas – a process commonly referred to as “spot” UV coating. In either process, the UV coating has the potential to deepen the color of the print, so when you use it in print projects, it’s a good idea to take this into consideration. Spot UV printing sounds pretty space age, but the technique itself is not complex. Probably the most high-tech aspect of the process is the fact that it utilizes UV light to “cure” a varnish that is applied to paper or card stock, sealing in their color, adding shine, and protecting the printed surface underneath from moisture and other types of damage.
Debossing & embossing are two separate techniques used to imprint images onto paper, leather or vinyl. In embossing, an image is pressed into the material so that the image raises from the surface.
In Debossing it is the opposite of embossing the area around the image which is pressed so that the image is pushed down into the material rather than being raised.
Ornamental designs are created in threads of silk, cotton, gold, silver or other material, upon any woven fabric, leather, paper, etc. with a needle. This is an art that is used traditionally and long lasting.
If you want to print on mugs, license plates and other popular hard surface items then Dye Sublimation printing is your answer. Dye Sublimation, as a process is really very simple. It is the method of applying an image to specially coated ceramics, metals and polyester cloth, using three main ingredients: sublimation ink, heat and pressure. Sublimation ink is unique in its ability to convert from solid to gas without going through a liquid form. (Example: dry ice). The conversion is initiated by heat and controlled with pressure and time. Hard items such as Ceramic, Fiber board, Metals, etc., requires a special coating to accept the sublimation inks. When you apply this to 100% polyester (ie: mouse pads and puzzles) you do not need any coating, it can be applied directly to the 100% Polyester fabric.
In traditional pure etching, a metal plate (usually copper, zinc or steel) is covered with a waxy ground which is resistant to acid. The artist then scratches off the ground with a pointed etching needle where a line appears in the finished piece, therefore exposing the bare metal. The échoppe, a tool with a slanted oval section, is also used for "swelling" lines. The plate is then dipped in a bath of acid, technically called the mordant (French for "biting") or etchant, or has acid washed over it. The acid "bites" into the metal (it dissolves part of the metal) where it has been ‘exposed’, leaving behind lines sunk into the plate. The remaining ground is then cleaned off the plate. The plate is inked all over, and then the ink wiped off the surface, leaving the ink only in the etched lines. The plate is then put through a high-pressure printing press together with a sheet of paper (often moistened to soften it). The paper picks up the ink from the etched lines, making a print. The process can be repeated many times; typically several hundred impressions (copies) could be printed before the plate shows any sign of wear.
Most plastic sheets perform superbly in a wide range of graphic applications and can be used to create weather-resistant signs, displays, or P-O-P materials. Their smooth surface is ideal for all types of graphics, and they require little surface preparation or treatment. This article focuses on Polycarbonate (PC) and Polyvinyl Chloride (PVC), both of which are commonly used for signage and graphics. The surface of PC or PVC sheets is cleaned before printing. Isopropyl alcohol and a clean cloth are used to clean the surface and remove static electricity. In some cases, certain pre-treatments may also be required.
