  • Is training production line workers creating a challenge? No problem!  Posted 7 years ago
    Companies rely on engineers or technicians to keep production lines up and running. These job functions are essential to hitting production targets, so it is key that their skill level on equipment is proficient. When making the decision to replace this equipment, the amount of time and money that will have to be invested in training your labor is a major deciding factor.
  • How do I get labels to stick in hot and humid environments? Posted 4 years ago
    Something to be aware of when considering using labeling for product identification in a hot or humid environment is that labels are sensitive to temperature, making facility environment temperature a determining factor in choosing what label material to use on a product.

Four Flexible Options to Enable Effective Large Character Ink Jet Case Coding Under Adverse Conditions

By Steve Liker, Product Manager – Large Character Ink Jet



Case coding would be so be simple if all factories were at ideal temperature, all flooring and transports were flat; there were no space limitations and all boxes were perfectly square.  But that’s typically not the case.  Diagraph offers four options to make their large character Impulse Ink Jet case coder flexible and capable of printing under adverse conditions. 


Low temperature printhead controller, roller retraction bracketry, angled conveyor mount, and right angle mounts offer customers flexibility to satisfy their application needs.


1)      Low Temperature Printhead Control for Cold Ambient Conditions

Printing onto dairy products, frozen vegetables and other heat sensitive products requires capability to control the printhead temperature and ink viscosity at low ambient temperatures.  Diagraph offers a printhead module that has additional heaters and temperature control in environments as low as 32° F. 


2)      Roller Retraction Bracketry for Irregular Cartons

Boxes and trays are often not square and can shift on the conveyor.  Diagraph have developed spring retractable brackets that position the printheads relative to the changing surface of the cartons.  This enables regular and irregular cartons to roll smoothly past the printhead rather than sliding over guide rails.  This eliminates production of corrugated dust that can clog printhead nozzles.  It also controls the throw distance - a primary factor in the sharpness of ink jet print.


3)      Angled Conveyor Mounts (ACM) for Angled Conveyors

For angled conveyors with slant from 0 – 90 degrees, Diagraph’s ACM printhead can meet the need.  The printhead swivels and locks into place to print at any angle.


4)      Right Angle Mount for Restricted Conveyor Space

This right angle printhead was designed by Diagraph for applications where little room is available at conveyor side for mounting.  The print engine portion of the printhead is separated from the body and turned at 90 degree angle so that the conveyor-side space is minimized.  And Roller Retraction Bracketry is compatible!

So if you are facing a carton coding application challenge, Diagraph offers flexible options for Large Character Coding.
