When we talk about printing machine, the first thing that comes to our mind is the equipment used for making various printed products. The printing machinery that we have today is a result of the advancement in science and technology. The various features that these machines possess make the printing process much easier than it was earlier. Some of the important types of printing machinery include roller printing, direct printing, duplex printing, discharge printing and resist printing.
Roller Printing – It involves the use of copper cylinders or rollers which are engraved with design. A large central cylinder through which passes the cloth to be printed is also present. Furnished rollers containing different colours move in between the engraved rollers and the fabric to be printed. The coloured dye is transferred on the engraved part of the rollers to form the designs on the fabric.
Digital Printing – This type of printing is very common and involves using a printer to reproduce an image or text on a piece of paper. The ink is dropped on the paper and the heated drum reproduces the text or images in a way that it can be seen. This type of printing can be used to create high-quality materials in a short amount of time.
Offset Printing – This type of printing is perfect for creating large volumes of print material. It uses flexible photopolymer printing plates that are wrapped around rotating cylinders. These plates have a raised image of the content that is inked and as they rotate at high speeds, it transfers the inked image to the paper. This type of printing is suitable for long-run production and it can be used on a wide range of media including plastic, cellophane and metallic film.
