6 Functions of Doctor Blade: Nip Roll Replacement
In the world of modern printing, the Doctor Blade or printing knife or ink scrapper plays an important role in ensuring the quality and consistency of printing results. Yes, after the presence of Doctor Blade, the printing world seems to be greatly helped. Given that before the Doctor Blade existed, many industries used a rubber roll commonly known as a nip roll or fountain roll for ink removal tools. However, these tools wear out quickly and are prone to damage.
Furthermore, the functions of Doctor Blade in the printing world are quite diverse. In fact, many are not aware of this so there are still those who use nip rolls which actually have poor results. For that, let’s get to know the function of the Doctor Blade more deeply. Here’s the review!
1. Better Ink Settings
One of the main functions of the Doctor Blade is to adjust the frequency of ink that will be applied to the cylindrical surface of the mold. Proper installation of the printing blade will be easy to adjust with the appropriate angle. Well, the Doctor Blade is able to effectively control the thickness of the applied ink layer. This is important for creating printing results with the desired quality and ensuring optimal color consistency.
2. Clears Significant Ink Excess
In addition to managing the ink, the Doctor Blade is also responsible for removing excess ink from the surface of the mold cylinder. The Doctor Blade’s working process is to gently swipe the surface of the mold to remove unneeded ink, so that the resulting print has clear details and not too much ink.
3. Improves Print Quality
By accurately controlling ink thickness and distribution, Doctor Blade significantly improves print quality. The resulting prints have exquisite sharpness, detail, and color consistency, meet high quality standards, and satisfy customer needs.
4. Reduces Ink Waste
The use of Doctor Blade helps to reduce ink wastage in the printing process. By removing excess ink, the doctor blade helps optimize ink usage, reduce production costs and improve operational efficiency.
5. Maintains Printing Machine Performance
In addition to the direct benefits of producing high-quality printing results, Doctor Blade also helps in maintaining the performance and lifetime of the printing machine. By regularly cleaning the surface of the molding cylinder, Doctor Blade is able to reduce the risk of ink buildup that can interfere with machine operation and cause damages.
6. Adaptability in Various Molding Processes
One of the advantages of Doctor Blade is the ability to be used in various types of molding processes. These include offset, flexo, rotogravure and others. This makes it a versatile and effective solution in various printing applications.
With its various important functions in the printing process, the Doctor Blade plays an irreplaceable role in creating high-quality, efficient and consistent printing results.
From managing ink to cleaning excess, Doctor Blade makes a major contribution in improving print quality, reducing ink wastage and maintaining press performance. For optimal results always use Doctor Blade from Dr. Pondberg
