	Anilox - Wikipedia, the free encyclopedia
		Anilox rolls are often specified by their "line screen", or, the number of cells per square inch.
		Similarly, anilox rollers that are used with water and oil based inks, which dry when left sitting out and unagitated, must be cleaned immediately after use or a problem known as "plugging" occurs where miniscule amounts of ink dry in the cells.
		Anilox rolls were originally made using a diamond pecking machine, but modern rolls are laser engraved.

	Anilox (Site not responding. Last check: 2007-10-08)
		In printing, "anilox" is a method used to provide a measured amount of ink to a flexo printing plate.An anilox roll is a hard cylinder, usually constructed of a steel or aluminum core which is coated by an industrial ceramic whose surface contains millions of very fine dimples (cells).
		Experienced press operators are skilled at determining the appropriate anilox rolls for a given print job.Though large wide-web flexo rolls are only manuverable by overhead crane, on smaller presses anilox rolls are often handled directly by operators.
		This leaves tiny, but unacceptable, pinholes in anything printed from the roll in the future.Anilox rolls were originally made using a diamond pecking machine, but modern rolls are laser engraved.

	Anilox Roll Inspection: So Simple, So Important
		An anilox roll not cleaned properly after its last use often will show the pigment color of the last ink used and obviously must be cleaned.
		A well-lit area where the anilox roll is supported by precision bearing blocks is all that is needed to inspect the engraved surface visually.
		Both the 30x and the 100x scopes have limitations for anilox roll inspection, but they are also the least expensive way to put a valuable tool in a printer's hands to determine if a roll is serviceable for a press run before it goes in the press.

		The ink metering roll, generally called the anilox roll, is usually a metal or ceramic coated roll, engraved over its entire surface with tiny cells numbering from 80 to over 500 per lineal inch.
		The metered anilox roll is moving into light kiss contact with the image areas of the plate, and the plate cylinder is moved into kiss contact with the substrate to transfer the image.
		When a thin metal or polyethylene doctor blade is used with a two-roll unit, the nip-point between the fountain and the anilox roll is opened to allow ink to flood the anilox and fill the cells.

	Method of and apparatus for loading a wiper roll against an anilox roll - Patent 5657694
		A controller detects rotational movement of the anilox roll and stops the translation movement of the wiper roll towards the anilox roll at a specific time after detecting the rotational movement of the anilox roll in order to properly load the wiper roll against the anilox roll.
		The two methods are using a doctor blade in conjunction with the anilox roll and using a wiper roll in conjunction with the anilox roll.
		The contact force between the wiper roll 12 and the anilox roll 14 determines the amount of ink film which remains on the anilox roll 14 along with the ink in the cells of the anilox roll.

	Anilox
		An anilox roll is a hard cylinder whose surface contains millions of very fine dimples (cells).
		The roll is immersed in a bath of ink and a 'doctor blade' is used to scrape excess ink from the roll surface leaving just the measured amount of ink in the cells.
		The roll then rotates to contact the flexo plate which receives the ink from the cells for transfer to the print material.

	[No title]
		Fountain roll and anilox do not rotate at the same speed- fountain roll is driven more slowly than the ink metering roll, causing it to wipe away excess of ink from the surface of the metering roll.
		The anilox roll (metering roll, engraved roll, ink aplicator, ink transfer roll) is engraved mechanically or laser engraved.
		The cells in a mechanically coated anilox are in the form of an inverted pyramid.

	How to Make Anilox Roll Improvements Work for You
		There are some exciting new developments in anilox roll technology, but they won't bring the results you want until you fine-tune your print process by attending to basics.
		Worn and plugged anilox rolls will not deliver the same volume as rolls that are clean and well maintained, even if they were engraved to the same specifications.
		Anilox manufacturers seem to be in a fierce race to develop higher line count engravings.

	Anilox Rolls - Maintenance
		I have seeen so many wonderfully engraved anilox rollers that are capable of two to five times the life expectancy they are seeing and are gone before their time only because of the inability to "maintain" the anilox roller.
		The most popular and endorsed by most anilox roller manufacturers is a stainless steel brush and a cleaning solvent as the best way to keep a laser engraved ceramic anilox roller clean.
		On roller covers that wrap around the anilox roller there should be a pocket which is there to write the screen count, volume, degree pattern and any other pertinent information about the anilox roller on it.

	Converting Magazine - Ethics in the anilox-roll audit process (Site not responding. Last check: 2007-10-08)
		When the focus is on the anilox roll, more often than not the printer will defer to a technician from an anilox manufacturer to examine the microscopic cell structure, and see whether it may be contributing to print defects.
		The anilox maker has the position of power, because the package printer is relying on the anilox manufacturer to provide an unbiased evaluation of the roll's condition and recommendations for corrective action.
		Because the anilox maker is preparing a report, which the customer often uses to identify rolls needing repair, resurfacing, or replacement, the technician struggles with a conflict of interest.

	Harper Anilox Rollers: Understanding Anilox Line Screen
		Line screen indicates the number of cells per linear inch on an anilox roll, and is a major component when specifying an anilox roll.
		The reasoning behind this is that lower line screen anilox rolls typically have higher volumes and carry larger amounts of ink or thicker ink films.
		Most importantly, a printer must choose the best line screen for their anilox roll to meet the needs of the specific job he or she is printing.

	Superfinishing your Anilox Rolls
		When a ceramic anilox cell is created by laser, some of the ceramic is vaporized, some is blown away by air jets, and some is redeposited on the surface of the roll.
		The premise behind the use of a doctor blade is that the volume of ink delivered to a plate is controlled through anilox cell size and geometry.
		Anilox rolls scored badly enough generally must be sent back to the manufacturer for re-covering, as the printing results from using them tend to show unacceptable lines in the print.

	anilox-clean-lanska
		Regardless of the operating frequency and the associated aggressiveness of the agitation, ultrasonic systems are still dependant on the cleaning chemistry to soften the ink.
		Because the anilox cells were smaller than the media, particles could get stuck in the cells.
		Because anilox cells are originally formed by concentrating laser energy at the roll surface, the laser cleaning process raises concerns about the effect on the cell walls from the application of this type of energy for cleaning.

		This anilox roll cleaning system is available in the form of a cleaning service, or equipment may be purchased for in-house use.
		Available as a service or as equipment for in-house use, ultrasonic cleaning systems are effective for cleaning laser-engraved ceramic anilox rolls – even those with high screen counts – but operating procedures vary greatly with the size of the roll, the characteristics of the engraving and the design characteristics of the cleaning equipment.

	Superfinishing your Anilox Rolls
		Anilox rolls rough with recast tend to deliver higher ink volume initially, because the vibrating blades are not shearing ink cleanly from the surface of the anilox roll.
		Over a relatively short period of time, the peaks are worn or broken away, allowing the blade to come more fully in contact with the cell wall surfaces. As a result, the volume is reduced from its "artificially" high initial delivered volume, and falls more in line with the long-term volume expectations for the roll.
		Therefore, the smoother a roll is when it comes from the manufacturer, the more smoothly a doctor blade will ride on its surface, and, the more fully the blade contacts the surface the more consistent the ink volume delivered by the roll will be, over time.

	Anilox roll advancements raise the quality of flexo
		New anilox roll technologies and materials have paralleled the rise of flexo, and it's no coincidence.
		The vast improvement in the quality of flexographic printing over the past ten years has resulted from a number of factors, including ongoing improvements in printing plates, inks, coatings, metering systems, and other critical components of the printing process.
		Finally, with the recent emergence of "wide narrow web" presses (with print widths from 22 to 30 in.), anilox roll manufacturers have developed ultra-light rolls that accommodate the wider widths without significantly increasing the weight of the anilox roll itself.
