How Commercial Printing Presses Work

Back in the 15th century, the first book was printed on the first ever printing press. Small blocks of letters were placed together, brushed with ink then stamped on the parchment. Since then, the technology has changed drastically. The concepts are similar, but the speed and equipment look nothing alike.

Printing Types

Unlike in the Middle Ages, the modern printing press offers multiple types of printing. Offset, relief and gravure all use a printing plate to transfer ink to the material but operate differently. Offset printing uses a roller to transfer images from the inked plate to the printing material. Relief printing is the most popular and harks back to the original press with the reverse material put on a plate, inked then pressed onto the material. Gravure involves digging out the plate versus raising it to create the material, inking then pressing onto the material. Many of these presses use doctor blades for flexo printing to prevent the ink clogging up the machine. There are other types of printing but not as commonly used.

Ink Colors

Printing is available in full color, black and white or grayscale. Full color requires the use of four distinct colors to produce the color spectrum: black, cyan, yellow and magenta. Black and white printing only uses black ink making it a cheaper alternative to color. Grayscale helps create images because of the optical illusion created by using dots of black in a variety of sizes to create a picture. The type of color scheme you use depends on your budget, application and needs.

Printing Presses

Printing presses may no longer look much like they did when Johannes Gutenberg created movable type in 1450, but they follow similar principles to deliver sharp or contrasted images and words. A variety of material can be printed on from clothing to paper to vinyl.…

The Basics of Boiler Water Feed Systems

Many industrial companies still rely on the use of boilers for efficiency operations. Depending on the deign of system, there will be considerable pressure on the boiler feed water process to create quality steam generation. Without a highly functional system in place, you may find corrosion and scaling in the system and experience an equipment failure.

Increase Boiler Efficiency

Costly repairs and equipment downtime can be avoided by using a high quality boiler feed water treatment system. There are several components that can increase efficiency, but the deaerator plays an important role. Using both chemical and mechanical deaerator parts, the deaerator provides the highest quality water for the feed water system by removing impurities and gasses out of the system prior to use. It has four primary uses.

  1. It heats the incoming cold water to avoid thermal shock to boiler system.
  2. It helps to remove dissolved oxygen and minimize the need to use water treatment chemicals.
  3. It works to remove dissolved gases and prevent corrosion and oxygen pitting.
  4. By removing non-condensable gases, it improves the steam potential and efficiency of the system.

Cleaning Out the System

When the right parts and elements compliment the entire system, it avoid plants shutdowns and costly downtime as a result of a boiler failure. These systems also prolong the life of the equipment, saving additional funds for the company. A treatment system for boiler feed water generally combines several technologies to remove suspended solids, dissolved solids, and organic material from the freed water. Within these harmful elements, the treatment system is used to remove iron, silica, copper, magnesium, calcium, and aluminum. These are materials that create scaling and corrosion.

By improving the efficiency and capacity of your machinery and equipment, you work to improve your bottom line finances. If you don’t keep your items in good working condition, you will be spending more time on repairs than operations. This only takes away from your profit. Spend your time and money wisely, and be sure your system is working properly.…
