What is anilox volume?
Anilox Volume. The amount of ink that is transferred from a cell depends upon the carrying capacity of the cell, or the cell’s volume. Volume must be accurately measured and maintained and is THE Primary Controlling Factor In Flexo Printing.
How do you calculate the volume of an anilox?
- Volume: cm³/m² = BCM/in² x 1,55 (*) BCM/in² = cm³/m² ÷ 1,55.
- Linescreen: l/cm = lpi ÷ 2,54. lpi = l/cm x 2,54.
- Abbreviations and habits:
What is LPI in anilox roll?
Line count. Line count measures the finesse of the pattern on the anilox roll. It measures how many cells are engraved per centimetre or inch. In Europe the standard is LPCM or lines per centimeter. In America, the standard is LPI or lines per inch.
What is the purpose of the anilox roll Why does it have surface cells?
The purpose of the anilox roller is to pick up ink from the fountain roller (or, in some configurations, directly from the ink fountain) and deliver a predetermined, metered, uniform amount of ink to the rubber printing plate.
What does BCM stand for in printing?
BCM stands for Billions of Cubic Microns. In printing, cell volume is the capacity of the engraved surface in a square in and is expressed in BCM. A high cell volume means higher solid ink density and a heavier thicker coating.
What is BCM in flexo printing?
Billion Cubic Microns (BCM) is a term used to express the carrying capacity of anilox rolls. Anilox roll is one of the key components in flexo printing.
How do you convert LPI to Lpcm?
- 1 LPC = 2.54 LPI. Cell volume is the ink carrying capacity of a cell multiplied by the number of cells in. a given square inch/meter of roll surface. The common unit of measurement in North America is BCM/in2 or billion cubic microns.
- 1 INCH = 25400 microns.
- 1 BCM/sq in = 1.55 cm3/m2.
What is BCM in anilox roller?
Anilox Cell Volume. Cell volume is the capacity of the engraved surface in a square inch, expressed in billions of cubic microns (BCM). Higher volume translates to higher solid ink density, more color or a heavier coating thickness.
Why is the anilox roller so important in flexography?
The Anilox Roller is often referred to as the heart of the flexographic press. It is designed to deliver a precise and consistent amount of ink to the printing plate.
What is BCM anilox?
What is BCM mining?
Bank Cubic Metre (BCM) is a volumetric term commonly used in the mining industry. BCM represents the contents of a cubic meter of rock in place, before it is drilled and blasted. We have found 21 more results for BCM. Billion Cubic Meters. Units.
What is a good anilox volume for a 1000 line screen?
If an anilox volume of 3.2 BCM was engraved at 1000 line screen, cells would be much too deep. In correlation, a 3.2 BCM anilox at 120 line screen anilox would result in cells being much too shallow. With increased ink strength and lower anilox volumes, higher line screen anilox rolls can now be used.
How many cells per linear inch is an anilox roll?
That is, if an anilox roll had 800 cells per linear inch and a volume of 2.0 BCM, then it was an 800 @ 2.0 BCM. Why? Do we print with anilox line count, the number of cells per linear inch?
What are the benefits of using lower volume anilox rolls?
Reduced VOC emissions are another benefit of using lower volume anilox rolls. It is the same concept: less ink gives off less VOC emissions. It is that simple. Line screen is chosen in direct correlation to anilox volume. For example, an anilox volume of 3.2 BCMs, requires a line screen of approximately 500.
Can I use higher line screen anilox rolls with higher BCM?
In correlation, a 3.2 BCM anilox at 120 line screen anilox would result in cells being much too shallow. With increased ink strength and lower anilox volumes, higher line screen anilox rolls can now be used.
