The Reason behind Doctor Chamber Leaks

The doctor chamber of the flexographic printing process is where all the magic happens.  When the material to be printed on, the substrate, is run through the doctor chamber inks and dyes are applied to the substrate which is pressed over a plate with an image cut into it.  This allows the inks and dyes to form the shapes and shades of the plate image to create a beautifully printed product.  This is currently the most efficient and most accurate printing process on the market, giving a variety of great results to so many production companies and printers around the world.

When a leak in the doctor chamber occurs it can cause a great deal of waste and even ruined material for the printer.  Here are some reasons leaks occur:

•    Wrong end seal – If the wrong material is in place as the end seal the chamber will leak and cause waste.

•    End seal not installed properly – Seems kind of obvious, a tight fit is needed to keep this process tight and working right.

•    Worn end seals – When the end seals get worn from multiple uses and need to be replaced its important to do so, continued use can cause a leakage.

•    Wrong end seal size and shape – This is critical, fitting the end seal correctly for different substrates is part of ensuring the right fit.

A leakage can cost a printer a lot of money in ink and dye costs.  It’s important to test and make sure all parts of the doctor chamber are properly aligned, fitted, of the correct material and ready to do the job.  When unsure about what the right fit is or material to use printers should consult their flexographic accessories vendor to learn what the correct settings are to make sure they will have a great fit and fantastic printing experience with little to no leakage during the entire process.
