Causes of Web Breaks when Conducting Web Offset Printing

Business Services

Instances of web breaks can occur during printing. This generally disrupts the process as the machine comes to a stop. Stoppages of the machine cause high wastage along with low efficiencies and productivity. Dallas printing services take precautions to ensure this does not occur when serving their clients. There are several major reasons why web breaks occur during web offset printing.

Reel Defects

Certain paper reels exhibit defects from the manufacturer. They include irregular shape, poor joints, poor winding, foreign objects, loose reel core and glue within or at the sides of the reel among others. Such defects will in most cases occasion web breaks during the run. The reel could also have sustained damage owing to poor handling, transport or storage. Carrying out your printing in Dallas is an ideal way of avoiding web breaks due to reel defects.

Reel Stand Fault

Fault reel stand is yet another main cause of web breaks during web offset printing. The reel stand has been designed for applying just the appropriate tension required on the reel, as set by the pressman. Utilising electronic and pneumatic controls or in calibration of tension rollers results in either low or excessive amount of tension. This leads to web breakage and eventual stopping of the machine. The DFW printing services Dallas has today factor in such considerations leading to high-quality output.

Poor Tension Controls

The pressman gets to adjust web tension parameters during press operation. This is done as per press and paper conditions. The operator can increase or decrease paper tension remotely at the main controls as proves necessary. This console enables the pressman to manipulate paper tension at reel stand, following the print unit or at the folder via a central screen, by simply touching a button. The web breaks down, with the machine stopping, if tension is increased or reduced excessively. Dallas printing agencies offer proficient support to anyone requiring their services.

Poor Ink and Water Balance

The process of lithographic offset printing relies heavily upon the principle of heterogeneity of water and oil. This is performed by applying oil-based ink and water-based dampening solution onto printing-plate surface. Oleophilic is the term employed in reference to the areas on the plate where the image forms. These attract oily ink, repelling the dampening solution, whereas the hydrophilic non-image areas on the plate attract the dampening solution while repelling oily ink. Excessive water usage while printing can cause web break during offset printing. Finding an experienced Dallas printer can help to avoid such problems.

Poor Splice Pattern

Paper reels are availed in diverse sizes, with their diameters and weights varying based upon paper mills. Many reels may be needed depending upon how many copies are required. The reel stand has to be replaced to avoid stoppage as one reel gets consumed. A splice pattern has to be made from this replacement to take place automatically at high speed. Eventually, a poorly-made splice pattern develops, causing web breaks. This is because the pasting is inaccurate or too strong to withstand paper-tension.
