Ink Transfer Technology — Dot gain and ink film thickness

Whether it’s the most complicated printing job or the simplest line work, controlling the Ink Film Thickness is very critical when it comes to providing a high quality in a repeatable print job. Commonly known print problems such and dot gain and dirty print contribute to a loss of time and money with customer rejections and reprint costs, short stops for cleaning plates, press downtime for re-mounting plates, and additional job hours and materials to complete the order.

As a general rule, the smaller the doctor blade tip thickness in relation to the contact area, the cleaner the wipe resulting in less ink film thickness and a cleaner print.The doctor blade tip must be matched to the specific anilox line screen in order to maintain the correct ink film thickness. Today many companies are spending high dollars on state-of-the-art printing presses, anilox rolls, plate material and inks, often not taking into consideration how much of an impact the doctor blade has and the game changer it provides to improve quality, service and costs.
