"Well to start off with, Printing can be defined as a process of producing texts and images, typically with ink and paper by a printing press. Printing is an essential part of any publishing business and is often carried out as a large-scale industrial process. Printing as a technology has come a long way and has improved a lot with time. The advancements have resulted in the development of various types of printing techniques. From the several techniques available, screen-printing is used most extensively worldwide.

Screen-printing is also known as silk screening and is a technique that is suitable for relatively flat surfaces. The process involves the use of a fine mesh or screen that is tightly stretched around a rigid frame, wherein the screen masks the areas, which are not to be printed. To create a print, the screen is placed over the item to be printed along with a blob of thick ink. With the help of a squeegee the ink is then pressed through the screen. The ink penetrates the unmasked area and creates the print, whereas the masked area prevents the ink from entering, thus creating the distinctions. The printed item is then passed through a heated tunnel to dry the ink so that the items can be stacked and packaged.

In case of multiple colors, the process is repeated by using different screens. Therefore, a four-color print will require four screens that are placed on a rotary press that allows proper alignment of different color prints and in coordination with each other. The improvement in technologies has resulted in the development of fully automated presses, which require minimum human intervention.

Screen-printing is extensively used for printing on t-shirts, garments, and other fabrics as well. It is also used on all sorts of substrates, ranging from plastic to metal. Screen-printing is a unique process as it is simple yet achieves intricate and bold details.

Screen printing is a process where ink is forced through a silk screen. This is often used on non flat goods e.g. clothing, mugs, etc. This is a popular method for large scale billboards and signage.

There can be two main types of printing, offset and digital printing. These two kind of printing processes have their own advantages and disadvantages. Some people may think that offset is better than digital printing or vise versa.

Even though digital printings have improved a lot over the years, most printing experts still prefer offset printing. It seems that the quality inherent in digital printing still have not reached the quality level of offset printing.

Environment conservation is a priority for all of us. We have now realized the urgency of keeping the environment free from harmful emissions and chemical interactions. Environment is hazardous and should be avoided or at least minimized to a great extent. The production and usage of various commodities should comply with eco friendly standards. This has given rise to the term ""environment friendly"" that essentially refers to the processes, products and services that cause minimum harm to the environment.

Screen printing is a method used primarily for flat or relatively flat surface printing. The procedure involves a fine mesh or screen securely stretched around a stiff frame. Sections that are not to be printed are blocked on the screen. To create a print, the screen is placed on a piece of dry paper or fabric and ink is placed on top of it. A rubber blade is used to spread ink uniformly across the screen. The ink passes through the open spaces in the screen onto the paper or fabric below after which the screen is removed. The screen is usually durable and long lasting and can be re-used after cleaning.

Thus, screen printing plays an important role in our lives!"
