Printers and Publishers
Though you might not realize it, dry compressed air affects every unit in the Printing and Publishing industry.
Use of Compressed Air in the Printing And Publishers Industry
In Printing units, the following compressed air-powered pneumatic machines are used:
- Feeding Machine
- Pressing Machine
- Air Brush
- Press-fitting clap sleeves
Applications
- Roller adjustment
- Cutting paper
- Embossing
- Monitoring of paper reel
Problems
A major problem in compressed air systems is the presence of water, dust particles, oil (oil particles are introduced by lubricated air compressors), and solid contaminants, which can adversely affect air quality.
If the contaminated compressed air is used through pneumatic tools and machines, then there will be the following problems:
- Malfunctioning of pneumatic tools and machines
- Sluggish and inconsistent operation of valves and cylinder
- Corrosion in pipelines, cylinders and other components
- Increase in downtime
- Increase in maintenance cost of pneumatic machines/tools/controls
- Freezing in exposed lines during cold weather
Moisture in compressed air also leads to problems like :
- Loss of finish/gloss on the printing surface.
- Brittleness or unevenness of printed material.
- Poor print quality
- Increase in wastage due to dull and poor printing
- Sticking problems in automated material feeding and handling processes.
The Delair Solution
Remove water, dust particles, oil (lubricated air compressors introduce oil particles), and solid contaminants from compressed air.
Delair offers a wide range of refrigeration and adsorption dryers that remove water/moisture from compressed air.
Delair refrigeration dryers
This dryer operates on the method of cooling the air to near freezing point to remove the moisture and reheating it to approximately 10°C below the incoming compressed air temperature at nominal conditions.
Delair Adsorption dryer
The dryer is based on the principle of heatless regeneration and the physical properties of the desiccant to adsorb and desorb water vapour. It uses the pressure swing principle / purge air to regenerate the desiccant bed.
Filters
Delair also offers Pre Filters and Oil Filters, which remove dust particles, oil particles and other types of solid contaminants present in dry air.
Frequently Asked Questions
1. Where is compressed air used in the printing and publishing industry?
Compressed air is used in several printing operations, including feeding and pressing machines, air brushes, and press-fitting equipment. It also supports applications such as roller adjustment, paper cutting, embossing, and monitoring paper reels.
2. How does moisture in compressed air affect printing quality?
Moisture can directly affect the finished print by causing loss of surface finish or gloss, unevenness, and increased material wastage. Controlling moisture is an important part of air treatment for printing industry applications.
3. What problems can contaminated compressed air cause in printing equipment?
Dust, oil, water, and other solid contaminants can interfere with pneumatic components used in printing machinery. They may lead to sluggish valve and cylinder operation, equipment malfunctions, corrosion, higher maintenance requirements, and increased downtime. Moisture can also cause sticking during automated material feeding and handling.
4. What compressed air treatment does Delair offer for printing applications?
Delair provides compressed air dryers for printing industry applications, including refrigeration and adsorption dryers for moisture removal. It also offers pre-filters ,Fine filters and oil particle removal filters to help remove dust, oil particles, and other solid contaminants. These industrial air dryers for printing industry applications can be selected according to the required level of compressed air treatment.
