The principles of cylinder engraving enable the engraver to produce quality work that meets the set standards. They are the rules and regulation that governs the whole engraving process to ensure the best quality engraving has been produced. So, what are they?
Well, if you are starting off in this engraving industry or have invested in the field that requires engraving services, this guide is for you. We have put together key principles that you need to observe when engraving cylinders:
Machine Quality Matters
The first thing should be about the engraving machine. Nothing much changes about the cylinder because it remains the same. What you can play around with is the machine. First, get the right machine for cylinder engraving. Make sure that you have understood what is needed for the engraving to get the right machine. Quality matters, and this is something you cannot compromise because it affects the quality of the engraving.
Always Clean the Cylinder
The second you need to get right is the condition of the gravure cylinder, or the cylinder you are engraving is in. The cylinder must be cleaned thoroughly before engraving. First, ensure that you have removed the previous ink and also the dirt and dust on the surface. This is a crucial factor that can affect your engraving quality.
Remove the Previous Engraving
This is important for a cylinder that has been used before. You need to get rid of the previously engraved image before putting on another one. This should not be difficult to do because there are ways you can have it done. There are machines specially designed to do this job, and you should have them in your plant.
Use the Right Beam Strength
The other important thing you must get right is the strength of the beam. This is an essential factor because it will affect the quality of the engraving and damage the cylinder. If the beam strength is too high, it damages the cylinder. Understand the right setting for every task.
Gravure Size Matters
Make sure that you understand the size of the etching to be made on the cylinder. It is another factor that will affect the quality of the engraving, and more so, it is for printing. Make sure that you have gotten it right.
Chrome Plating
Lastly, it is always important to chrome-plate the cylinder after engraving it. The layer of chrome hardens the cylinder surface and protect the engraved image from damages. The quality of the chrome also matters.
