Commercial Printing Will be here To Stay

Commercial printing comes about at about 10 0000 sheets per hour or 160 sheets per minute and can happen in four colours, i.e. cyan, magenta, black and yellow or CMYK in printing parlance. The ink is carried on a pressed aluminium sheet and the picture is hard pressed onto the paper by rollers, one at a time. This procedure is termed lithography and is suitable for the printing of magazines. Additionally, there are other print approaches for diverse printing requirements.

Large and sophisticated printing presses literally cost millions of Rands and are utilized on a 24/7 basis to guarantee the required return on investment capital. The vast majority of magazines and newspapers printed in South Africa may have been printed by one of the two largest commercial printers in the country. Apart from magazines and newspapers, these printing presses also provide an array of other printing tasks to soak up any spare capability, like bill boards, prints etc. Some of our scaled-down towns where a neighborhood or local paper among other things may be printed might still use letterpresses, which can be old and relatively cheaply come by. They use lead as the image carrier and are utilized on short runs. Whilst they are costly to operate a vintage machine with little continuing capital value can be to be financially viable in the situation defined.

The five types of commercial printing currently employed are:

o Lithography (previously identified) used for the printing of magazines on short to lengthy runs at low cost. o Letterpress (already referred to) used on short runs at high cost. o Flexography, using rubber as the image carrier. Utilized on long runs, at moderate cost. o Screen printing, using polyester, metal or nylon as image carrier. Short to long runs at low cost. o Digital printing using Photo-receptor technological innovation on short runs at low cost.

The printing tactic to be used in commercial printing will mostly count on the task at hand and the medium to be printed on and any application is best talked about with a printer to make certain the correct process is used at the best charge advantage to the desired job. Digital printing is evolving each year and holds certain advantages over standard printing, but although the cost thereof is favourable the speed, volume and print media has to be further created before it would truly take on say lithography printing.

Desktop printing happens to be pretty innovative, but equipment particularly at the entry level uses expensive ink technology and is less than ideally designed for large sheet printing. Even at the level of volume printing of leaflets, paper prints and other marketing and advertising material, commercial printing remains to be the technology of choice especially on long runs. Commercial printers at the lower end of the volume scale tend to specialize in their printing offers and do much work in the office stationery arena as well as other short run jobs for artwork and printing jobs requiring silk screening. Those letter press printers in smaller locations often do printing from newspapers to marketing material to office stationery in order to achieve critical mass versus cost.
