Screen Printing (Serigraphy)

Screen printing is a printing process in which we use a mesh for ink transfer over substrate by using stencil. In Stencil, areas are made permeable so ink can pass and form an image, and areas made impermeable blocks the ink, hence forming a non-image area. A squeegee is is moved across (from top to bottom direction of stencil) screen to fill and open mesh apertures with ink, then a reverse stroke is made which causes screen to touch substrate momentarily along the line of contact. This makes ink to wet the substrate and is pulled out of mesh apertures as screen springs back after blade has passed. One color is printed at one time, so multiple screens can be used to produce a multicoloured image, graphic or design. There are many terms used, which is essentially same technique. Traditionally, this process was known as screen printing or silk-screen printing, because silk was used in process. It's also called as serigraphy and serigraph printing . At present, synthetic threa

The Medieval Packaging: The era of hunters and gatherers

When the earlier cities were domesticated a plethora of packaging materials were used for storage, transportation and protect the essential items. Early protective packaging designs were made of plant leaves and animal skin as they were easily available in the proximity. Bottle Gourds Nuts and bottle gourds were used by these prehistoric people and radiocarbon dating indicates their presence in the Americas by 10,000 years ago. The ancient Egyptians were the first to industrialize glass
