Advancement in technology has led a great progress in printing methods. Today, several printing processes have come to be useful for businesses – it’s been possible customize to the needs of each business. Before the invention of the printing methods people suffered a lot for making printings to promote their business. It has been a pain-stacking process for them earlier to print books, brochures, broadsheets etc. Today, the job has become easy – many types of commercial printing techniques evolved in the market. Today, there are diverse commercial printing methods used by businesses and publishers according to the needs of their business. We’ll discuss here a few of them.
Offset printing or lithography
Offset printing is the common form of commercial printing. This is used for producing promotional item like brochures, newspapers, letterheads, etc. There are different kinds, sizes and qualities of offset presses. There are two major types – one is sheetfed and the other is webfed. In sheetfed form, the paper is cut into pieces of appropriate size and are run through the offset printer whereas in webfed form, the entire large paper rolls are run through the printer and are cut later. Both kinds of printing are used for producing different prints. Earlier lithography was used where the etched images on a flat stone, but in modern offset printing the image is first transferred to rubber blanket and from there to the paper. This is how printing is done in offset lithography.
It is also known as flexo. It is a versatile process that uses photo-etched plates. Here, the non-image area of the plate is carved or etched and only the printing surface is left, which carries the ink directly to substrate. Technology advancements made this flexography well suitable for the making prints on a substrate and it is supplied in the roll form. This type of printing is mostly used for labels, tabs, cartons, corrugated boxes, etc.
Letterpress is the conventional method and is the original process done by Johannes Gutenberg. In letterpress, the image area is raised above the rest of plate and then a physical impression is made on the paper. However, modern letterpress uses photo-etching technique.
With advancements in technology letterpress printing is less popular. Today, it is only used for special job-works like fine arts, books, posters, imprinting business cards, etc.
If you want high quality printing with a layout containing more images, you can use digital printing for the purpose. Digital printing is the most widely used method today in printing because of its multiple benefits – it doesn’t require huge set-up and man power, just takes the print directly from the computer and prints quickly with high quality.
It is a popular method used for printing letterheads and stationery even today. The images created by this method are attractive, they are printed on paper and are raised or engraved making a distinct. It is used mainly to create corporate logos or invitations for formal parties. It is expensive and involves skilled work.
It is a versatile form of printing process. In screen printing, the ink is sprayed through a stretched fabric mesh with the help of a squeegee blade for producing the original image on the substrate below. It can be done on a variety of materials such as, metal, plastic, paper and glass.
Electrostatic printing is completely different from above processes. In this process, the paper is coated with zinc oxide, which acts as a conductor when exposed to light and insulator in the dark. This type of printing is just used for short run printing for example geographical maps. It is famous because it does the printing faster than the inkjet printers.

Adequate supply of pure drinking water is the requirement for healthy life. Contamination of drinking water causes health hazards and some times leads to death. There are some common types of contaminants which pollutes water are given below.
Presence of microbes such as coliform bacteria and cryptosporidium in drinking water leads to contamination of water. This causes several diseases. Coliform bacteria is not a harm causing bacteria but its presence in water affects the distribution system and there by causes diseases to humans.
Cryptosporidium is a parasite that enters water through sewage and animal wastes. It has an outer shell that makes it to survive outside the shell and there by it become tolerant to chlorine disinfectant. Drinking water contaminated with this causes cryptosporidosis, a mild gastro intestinal diseases.
Drinking water contaminated with radio nuclides may increase the risk of cancer. Radio nuclide contaminants include alpha and beta emitters and radon gas. Some minerals are radio active and emits radiation known as alpha or beta radiation. People drinking contaminated water for long increase the risk of cancer.
Chemical contaminants in drinking water leads to health diseases. Some of the naturally occurring chemical contaminants that contaminates water are arsenic, fluoride and lead.
Fluoride in low amounts is added to drinking water to prevent dental problems. High amount of fluoride in water causes dental fluorosis and much higher amounts in water leads to bone fractures.
Arsenic is a toxic heavy metal. Excess amounts of it in drinking water leads to severe health diseases. It affects lungs, kidneys, bladder and liver. It also affects central nervous system. It increases the risk of cancer.
Lead enters into the drinking water through corrode plumbing systems. It affects children and pregnant women. Drinking contaminated water delays mental and physical growth of children and impairs learning capabilities.
These include carbon tetra chloride, benzene and chlorobenzene. Benzene discharged from factories and also leaching from gas storage tanks. Water contaminated with it leads to decrease in blood platelets and anemia. Carbon tetra chloride is discharged from chemical plants and other industrial activities. It causes liver problem and increases the risk of cancer. Drinking water contaminated with chlorobenze leads to liver and kidney damage.
Disinfectants are added to the drinking water to kill microbes in the water. Excess amounts of it affects eyes, nose and stomach. These contaminants include chlorine, chloramine and chlorine dioxide.
Anti-lock braking system is a powerful braking system used in modern automobiles. An anti-lock braking system prevents the wheel locking or skidding. An electrical control unit, hydraulic actuator and individual wheel speed sensors that work together to prevent brakes from locking. We’ll discuss in this article the components of an anti-locking brake system and its working.
The primary components of an anti-locking brakes are electronic control unit (ECU), hydraulic control unit/modulator, wheel sensor unit, power booster and master cylinder assembly.
Components of an anti locking braking system
Electronic control unit (ECU)
The main purpose of an electronic control unit (ECU) is to receive signals from different sources. A sensing device is located at the brake pedal that provides a brake-operating signal and another device is located in the ignition system to signals the engine operation. Another input signal is from the wheel speed sensors. These signals are used to control the hydraulic control unit/Modulator and wheel lock. When a wheel starts to lock, ECU operates a solenoid valve to reduce hydraulic pressure.
Hydraulic control unit/modulator
ECU sends electrical signals to the hydraulic control unit/modulator. It executes the command signals using three solenoid valves connected in series. These solenoid valves are connected with master cylinder and the braking circuits, one valve is connected to the front wheel hydraulic circuit, and one for both of the rear wheels.
When signals from the wheel speed sensor show no tendency for wheel to lock, the ECU won’t send any control current to the solenoid coil. The solenoid valve will be idle state, and the hydraulic pressure from the master cylinder is supplied to the brake unit at the wheel. When the control unit detects any lock-up, it sends a command current signals to the solenoid coil. This causes the armature and valve to move upward, and isolate the brake circuit from the master cylinder.
Master cylinder assembly
The master cylinder is connected to the brake pedal through a push rod. Master cylinder is divided in to two parts. It consists of a primary piston, and a secondary piston. During normal braking, as the speed of the wheel falls,electric current won’t flow from the ECU to the hydraulic unit. The solenoid valve is not energized. The brake master cylinder hydraulic pressure is applied to the brake unit.
ABS needs some sensing units to know when a wheel is about to lock up. For this, speed sensors are used. These are located near each wheel, in some cases they are located on the differential, provide this information to the control unit. This system provide maximum braking power.
When the ABS system is in operation you will feel a pulsing in the brake pedal due to rapid opening and closing of the valves.
