Components of Flat-bed machine

Though each die cutter may have various components based on the application, yet there are some elements that are common to all the machines, such as:

Feeder/ Loader: This section of the unit comes outfitted with suction heads that transport sheet material from the pile to the machine in feed.

In-Feed:  This section is responsible for controlling the movement & transportation of each individual sheet. With the help of mechanical or dynamic registration, the in-feed also registers the sheet material to the cutting tools.

Stripping Section: The stripping section functions as a waste removal unit, which aids in getting rid of internal waste, side, and rear trims. The two tools, upper and lower, work together to remove the excess material.

Blank Separation Section: This tool makes use of dedicated blanking tools to move individual cartons from the sheet material.

Delivery: In the absence of a blank separation section, the delivery creates a pile of full sheets or blanks.

Quick Tips for Reducing Delays on an Offset Printing Press

In the offset printing industry, delay accounts for almost 30%, which implies a loss of about one –third of the press time. There are several factors that may trigger a delay, but before discussing that, first, let’s have a look, what exactly constitutes a delay in this industry? It does not comprise makeready or dead time between tasks; rather, it refers to those times when production needs to be stopped for factors that do not pertain to the normal operation of the press. For instance, inadequate maintenance of the machine may result in a mechanical issue, which, in turn, may put the production on hold. Listed below are the most common reasons and their corresponding fixes for delays on new & Used Offset Printing Machines:

  • Web break on start-up

This may occur for several reasons, including, usage of too much or too little water, high blanket, excessive or inadequate tension, and many more. The resolution is simple – provide training to the pressmen so that there is little scope of human error.

  • Running Web Breaks

This is the second biggest reason behind a delay. While some may opine that running web breaks are normal delays and there’s not much that can be done in this aspect, the truth is that these delays can be prevented by providing training to the crew on the subjects of adjusting the infeed according to the paper density & quality, keeping a tab on the tension, and much more.

  • Mechanical Issue due to Inadequate Maintenance

Now, this is the cause of a delay for any machine. It is a known fact that proper preventive maintenance helps in increasing the life of the machine as well as prevents from frequent breakdown. A regular lubrication of an Adast Printing Machine or any other printing press of a reputed brand can go a long way in preventing unnecessary delays.

One should always remember that it’s not just about finding a fix to the problem, but it is essential to identify the root cause of the delay, so that it does not occur again.

While carrying out tasks on an offset printing unit, one needs to check a variety of things, starting from the condition of the machine, to the quality of raw materials, and much more.  Here are just some of the pointers that will ensure that one achieves the best results:

  1. Check roller settings

To start with, one needs to check the roller settings and ensure that they have been set as per the specifications listed out in the manual of the offset printing machines.

  1. Proper ink and water balance

There are so many problems that may occur due to an improper ink and water balance. One needs to remember that increased water always triggers piling. Again, low water may also enhance piling, simply because it would encourage deposit of ink particles on the blanket.  Hence, an optimum balance needs to be attained between the two factors. If one can carry this out successfully, one can surely avoid problems such as scumming, piling, and several others.

  1. Gumming of plates

At times, the plates are extremely sensitive; hence, it is important to make sure that they are being gummed properly.  It is a good idea to gum the plates, whenever the press is not being used for a considerable period of time.

  1. Paper quality

Printing is carried out on all varieties of paper depending upon the requirements of the customer. However, there are some papers that are uncoated, which makes the press easily deliver up to a lakh of copies without causing the blanket to undergo piling. On the other hand, coated papers can produce build up on the blanket merely after the press has delivered 30,000 copies. This is primarily because coated paper cannot absorb water and ink, thus leaving them to pile up on the blanket. Further, use of abrasive paper may damage the plates.

  1. Quality of Ink 

Though ink is accountable for only 3% of the cost, but it contributes to almost 97% of the quality.  It is for this reason that one should always make use of good offset printing ink. One needs to speak to the ink manufacturer to ascertain the water pickup value of the ink.

There are various aspects that go hand in hand in producing good quality printing on new & used offset printing machines. Ink is just one of these components. While working with offset printing ink, one may encounter a number of problems, such as high dot gain, piling, ghosting, scumming, doubling, slurring, non-gear streaks, and many more. Let’s have a look at some of these issues and their related solutions:

  1. High Dot Gain

This may be caused by two reasons – low viscosity of ink or improper balance of ink & water. In the first case, one may opt for increasing the viscosity, which may render an improved quality. Alternatively, one may also go for a complete change of the ink. In the second case, it is advisable to run minimum water and the minimum ink for attaining the proper density. At times, owing to specific properties of the ink, it may not create a proper balance with water. Hence, one should ensure to take a certificate of analysis from the ink manufacturer and make a note of the values that may suggest its water pickup attributes. Of course, high dot gain may also occur as a result of improper pressure settings, chemistry, or even plates.

  1. Piling

Poor ink and water balance is one of the major reasons behind piling on an offset printing press. To correct this, one may make use of anti piling agents that may be added to the fountain. One may also consider running the water just above the minimum level.  Poor quality of the paper may also cause the occurrence of piling.

  1. Low Ink Mileage

There may be several factors triggering this problem, such as high density of ink, rapid penetration into the paper, and low pigment strength. To avoid this scenario, one should ensure usage of quality ink and paper. Further, one needs to make sure to run only the required density and minimal amount of water.

Of course, there are several other problems that one may face in this aspect.

The 3 Major Drivers of Successful & Flawless Die-Cutting Results

For utmost precision and high-quality results, one may make use of new or used Bobst die-cutting machines.  

Used Bobst Die Cutting MachinesToday’s label production industry makes use of the rotary die-cutting procedure. This is primarily because in comparison with the flat-bed process, the rotary method demands lesser pre-tension, ensuring that the material is processed seamlessly, and that too, at great speeds. Owing to high customer demands, label printers are always in a hurry to complete their jobs. This makes die-cutting a challenge for them. Further, it is also essential to produce flawless results. For all those who are involved in the rotary cutting process, here’s an insight on the 3 major drivers of achieving high quality results.

  1. The material itself

If we look around, we will see a variety of self-adhesive labels being used day in and day out. These may range from personal care products, to medicine, food & drink items, retail, office stuff, logistics, and much more. These adhesives are basically multi-layered materials, having a printable face material, which is bonded with a siliconised backing material, by making use of an adhesive layer. The final die-cutting result will depend upon the thickness of this siliconised backing layer and the type of the material.

  1. The cutting unit

To get optimum results, one needs to ensure that the cutting unit is in perfect condition. It should be free from contaminants and wear & tear. Further, the gap is of paramount importance here. The gap is defined as the distance between the magnetic and anvil cylinders. Then, the initial pressure (or the pre-tension) also plays an essential role in ensuring precision. The use of a pressure control system makes things easier, as it aids in evenly adjusting the pressure on both sides of the cylinder. One may install new or used Bobst die cutting machines for great results.

  1. The cutting tool

Just like the unit, the tools should also be free from wear & tears and contaminants. Various tools are used depending upon the material, unit, and the application.
