ROLE OF ANILOX ROLLER IN FLEXO PRINTING |

The ceramic 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.
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, known as cells. The choice of the correct anilox roller is of central importance for an optimal printing result. Depending on the printing type, we recommend different engravings and cell volumes. The choice of the correct anilox roller is of central importance for an optimal printing result.
A flexographic printer often faces problems due to the nonavailability of the correct anilox roller. The purpose of this article is to make an attempt to throw some light on this very important subject.
Anilox roll:
The flexo printing/coating process depends upon the precise controlled transfer of a liquid ink, varnish or coating. An anilox roll is simply a metering roll designed to consistently supply a uniform and measurable volume of ink onto the image carrier.Anilox roll is considered to be the heart of the flexographic press. Older methods of mechanically engraving cells in to the surface of a roll have been replaced, to a large extent, by the precise computer controlled laser engravings of ceramic coated steel rolls. In this process, millions of minute holes (cells) are drilled into the ceramic surface of the roll. Ink receptivity and releasing capabilities of the anilox roll is of higher importance and ink transfer capabilities of the plate are determined by the surface technology of plate, surface tension of plate & ink and plate to ink compatibility.
The central part of the press is the anilox roller, the ink metering system unique to this process that allows the correct amount of ink to be carried to the printing plate. On the surface of the anilox roll are etched the cells which act as ink carriers.
The latest chrome anilox roller is laser engraved, with cell counts currently up to 500 cells/cm, from a steel roller and coated in fine ceramic. These laser engraved ceramic rolls could last up to 10 years, depending on the wear they are exposed to from contact with the doctor's blade. They provide an even, and consistent ink delivery in a controlled manner and provide narrow web flexo with a competitive edge in the leading packaging markets eg self-adhesive labels for wines. Once the anilox is ‘charged’ with ink, the excess is wiped off with a flexible steel doctor blade.
Besides the cell geometry, ink release capabilities of the cell are also affected by rheological properties of ink like; viscosity, surface tension, printing pressure between the plate cylinder and the impression cylinder, substrate properties, etc.
Anilox engraving angles:
Available engraving angles for anilox rolls are as follows; 90 degree angle, 45 degree angle, 30 degree angle and 60 degree angle.
In 60 degree anilox angle, the hexagonal cell offers 15 per cent more cells on the same area. Higher quantity of cells indicates a plus point concerning the ink transfer, as well as homogeneity.
Anilox sleeves:
Some of today's servo driven narrow web presses make use of anilox sleeves, which are much lighter than the standard solid anilox. The advantage is ease of handling and loading. On the narrow web side there is no difference in performance than with a conventional roll. Ceramic anilox sleeves initially were profiled in a scenario of short-run environments where anilox changes are very common and required, but have shown their usefulness regardless of the frequency of changeover. Sleeves are easier to store and inventory.
The disadvantages of sleeves are their cost as well as the different care and handling that is required. Converters need to design special racks to store sleeves so that the chance of damage is minimized. In addition, sleeves cannot be cleaned in the same fashion as rolls, which may add more time and cost.
Mirror rollers are generally used in plastics, packaging, printing, steel and other industries. Since traditional hard chrome electroplating cannot fully meet the requirements of wear resistance and corrosion resistance, our matting rollers can perfectly solve these problems. Its hardness is increased from HRV800 with hard chrome layer to HRV1200, the corrosion resistance is greatly improved, and the service life is long.
Dr blade materials, on the other hand, are a little more complicated of a subject than that of their shape. There are five materials commonly used to create blades today and they are as follows: plastic (UHMW/UHMWPE), stainless steel, carbon steel, tool steel and graphite. While the steel blades have upsides and are favored by many within the industry, current trends and advancements in technology are heating up the playing field for plastic and graphite.

Build Cambodia Email Address - Yes, But How Many Do I Need? |

If you haven't been told Cambodia Email Address to build email lists at least fifty times already, then you can call yourself a newbie! It's made out to be the key to everything, the secret to unlocking the door to that passive income Cambodia Email Address we are all in this for. But do we want one list, several or dozens? Firstly, let's look at the advantages of having more than one list: Most niches have sub-divisions. The obvious one Cambodia Email Address- internet marketing has several such as Search Engine Optimisation, Private Label Rights, Article Marketing, Pay-per-click, Affiliate Marketing, the list goes on.
So if you put up one squeeze page with a free e-book about article marketing, another about PLR etc Cambodia Email Address, then you should build lists that have say five messages pre-programmed into your autoresponder that are specific to this topic. But of course, a visitor who Cambodia Email Address signed up for a report on PLR. Almost certainly will be interested in other ways of making money online. So therefore if you build email lists that have five category-specific Cambodia Email Address messages going out (say every 2-3 days) then you can follow up that series of messages with other subject areas.
![[Image: Cambodia-Email-List.jpg]](https://sxxylpyidnht.wpcdn.shift8cdn.com/wp-content/uploads/2020/11/Cambodia-Email-List.jpg)
This is good because you can use the 'campaign sharing' facility on Aweber for example to drop the same messages into more than one list, after that Cambodia Email Address 'category-specific' first five. Also, as well as writing your follow-up messages and programming them into your sequence, you can send out 'broadcast messages' to any or all of your Cambodia Email Address. In fact, I would advise that your offers that you send to your list - hey, we are allowed to monetize not just build email lists, right? go out using the 'broadcast message' Cambodia Email Address facility. That way, they will always seen fresh and up to date. You can't promote a brand new ClickBank product and put it in your follow-up series, for most subscribers to discover it months or years old!

A lengthy update |

Hi everyone,
I need to post this here as I broke our front-facing website (more on that later).
We've been a bit quiet if you've not been around our Discord lately I'd like to take a few minutes to talk about why that is and what's been going on over the last year or so. There's a TL;DR at the end for those of you whom lack the time to read all the details.
What's the hold up?
The last 12 months or so have been quite a stressful time in the personal lives of the team, I won't speak of the others because that's not for me to discuss but I moved between jobs and had quite a steep learning curve that burned me out from anything outside of just doing that job, I didn't have the time or the motivation to organise events for TSG because I was flat from work. We had spent time trying to put systems in place so some aspects of the community could run themselves or at least have minimal input from us and at least keep things ticking along in case something like this happened but we just missed the mark on getting it in place.
So We Back?
There are some developments taking place, not all behind the scenes if you've been keeping track of things on Discord with a loose plan to return to organised online activities in late July/early August. So we not back yet* but it's coming real soon.
CANZStats and RocketSTATS
Part of the plans when it comes to keeping things formulated to be able to somewhat run themselves has been the establishment of an event/competition management platform. Stats has been a pet project of mine for some time now but we're fast approaching a point where I can start to think about how we can use it to manage our more competitive side of things. Starting, of course, with our racing and Rocket League arms but eventually looking at other games as well. Read on for a brief outline of how each Stats platform will aid us in organising things.
CANZStats
As far as organising series goes, the bulk of the work was in structuring everything and doing the results for rounds. When it came to updating championship standings back when we were Regional Gamers League Online Racing Community, that meant manually updating web pages and tables on forums. Hacking together pages with calendars and dates for events, who to contact with queries and the locations for each event. CANZStats automates the generating of a lot of this content. Admins create championships, add rounds at certain locations on specific dates to those championships, and then enters the results after each round. Championship tables are updated automatically and even factor in reports should points deductions be applied. Individual user profiles also track the users stats as part of their overall career so everyone gets a nice overview of their history with CANZ/RGL and eventually we hope to welcome other series onto the platform for them to be able to track their stats too. We're still in early testing for many features but hope to have an early public test build soon.
(For more info and a history of development check out the #statstalk channel on our Discord)
RocketSTATS
This one is a little more open-ended as thought has only started going into it in the last couple of weeks. As far as automating much of this goes we're taking a slightly different approach. Players register on the platform and start as free agents, they can create a team or apply to join a team. There are two formats of competition, ladder and knockout. When a knockout series is organised the teams apply in a first-in-format, the organiser sets the number of teams and the system will generate a knockout bracket based on the Team Rating's (TR's). A TR is determined by the Win/Loss ratio of the team as well as other factors such as Goals For/Against and average winning margin (how this is calculated is to be determined). A ladder format is the standard format for the platform, over a set period of time (determined at the time of creation) the teams will compete in a ladder tournament attempting to reach the top of the ladder by the end of the "season", similar formats to this limit the number of positions you can challenge above you on the ladder and that will be determined by the organiser. There's a bunch more planning to do here but this is the overview. Players will also earn a Player Rating (PR) for their overall career based on their overall stats as well as Match Ratings (MR) for their performances in individual games. We'll have more to talk about with this as we get closer to launch of the RocketSTATS platform.
CANZ Racing
As many might be aware, initially the name was "CANZ Racing Community" where CANZ stood for "Confederation of Australian and New Zealand Racing". We've changed it up slightly and it's now just "Community of Australian and New Zealand Racing". Not a huge change but for us its a perception that we're targeting a more social racing community with a hint of competitiveness (the Sporting Regulations aren't going anywhere) but nothing over the top serious, at least not to start out with. Once we build the community back up we can explore how we organise things.
Socials
Social nights have always formed a big part of the community aspect of TSG, now that a few of us have streaming capable connections (cheers NBN) socials are going to form an integral part of the rebuild phase of TSG's community, so keep an eye out for announcements of upcoming social nights here, Discord, and our social media!
Minecraft
The realm has been reborn! Jump on our Discord or contact me for an invite!
TL;DR:
Life got in the way, motivation was down but we almost back. There's some Rocket League, Racing, Socials and STATS galore coming! Minecraft is here now though!
