What is Napkin Flexo Printing Machine?
Flexo printing, also known as flexographic printing, is a direct rotary printing process that uses flexible photopolymer plates to imprint images onto a continuous substrate. This method is commonly used for labels and packaging. The napkin flexo printing machine uses a cascading design for printing and folding napkins. The machine has a lamination unit that can produce airlaid quality napkins at the same production costs, to create designs on napkins and other promotional products. They can print in multiple colors and designs on raw material, and then emboss, fold, count, and cut the material into squares and rectangles.
Features of Napkin Flexo Printing Machine
Flexible Speed
Our tissue flexo printing machine uses ceramic anilox rollers for ink transfer, and the unwinding uses magnetic brakes and imported frequency converters for speed control, maintaining flexible tension control during operation.
Multi-color Printing
This tissue flexo printing machine is equipped with independent embossing, printing and lamination units, and adopts a dual-channel printing design, which can complete the printing work of two colors at the same time.
Efficient Drying
The printing unit has a 360° plate registration adjustment function, and each printing unit has an infrared dryer to dry the ink. It also has a die-cutting station, which can greatly increase the speed of printing and die-cutting.
Auto-correct Function
Our flexo printing machine has a built-in infrared automatic counting and paper detection device. When it detects a position deviation, it will stop urgently to verify whether there is a paper break or paper jam.
Application of Napkin Flexo Printing Machine
Flexo is a popular method of commercial printing for a reason. But, did you know that there are some unconventional products that can be printed? Here are common, and maybe a few uncommon, applications that our customers use flexo printing for:
Paper Towels and Consumer Goods
Paper towels are ideal for Flexo printing not only because of their size, but due to the nature of the images being produced on the final product. Flexo printing, while not able to achieve immense detail in images, is fantastic for paper towel applications where the images are non-complex. This allows companies to achieve the efficiency and speed of Flexo printing, while still achieving specialty graphics (think snowmen around Christmas) on their paper towels. Additionally, this makes Flexo printing a great choice for other consumer goods such as:
●Wrapping paper and gift wrap
●Garbage bags
●Freezer and sandwich baggies
●Laundry bags
●Paper napkins and plates
Flexo printing is a solution for corrugated and liner board applications due to the precision of the process eliminating any risk of crushing the corrugated flutes. Corrugated materials tend to be recycled, and therefore abrasive on your flexo image carrier. The durability of elastomer sleeves outlasts that of photopolymer plates, saving you costly frequent image carrier replacement.
Food Packing
The Flexo printing flexo printing machine is used for food packaging. That is because the business can use non-toxic water-based inks to print on packages. As such, the contents of the package remain safe without a possibility of ink poisoning. Additionally, the ink dries very fast, which makes it ideal in the fast-moving food packing industry. Flexo printing is an ideal application for printing food containers such as bags and pouches due to the ability to process flexible packaging that is later cut into smaller final packaging.
Self-adhesive Labels and Decals
Labels are an important part of any company. These labels can be placed on large products or even on business premises to showcase or highlight anything the owner wants. For instance, the Flexo printing machine is fully capable of making high-quality floor tile decals. These decals can be used to convey a wide range of information from directions to advertising. Because of the COVID-19 pandemic, retailers can use social distancing floor decals to help customers know where they should stand while queuing to be served. Other examples of self-adhesive labels include:
●Car wraps to denote branding on vehicles
●Window wrap signage for temporary or seasonal business use
●Holiday decorating in large commercial spaces
One of the advantages of opting for flexo printing for these adhesive applications is that flexo image carriers can not only lay down ink for traditional printing, but can be used for laying adhesive. When working with a flexo supplier that can provide materials for both, you save yourself time and headache ensuring everything is registered and working together properly.
Pool Liners
Swimming pool liners definitely fall under the category of a large substrate printing application, making it ideal for flexo printing. After the printing process is done, the ink can be cured using strong UV light, making the detail of the print waterproof.
Home or Business Wallpapers and Decals
Similar to swimming pool liners, when printing wallpaper you want to opt for as seamless of a print on the large substrate as possible. When printing, you have the option of an elastomer continuous print sleeve to eliminate plate break.
If you are interested in acquiring a new printing press, but you are unsure of how flexo stands in relation to other printing technologies, the first thing to do is get as much information as possible. Never invest blindly. Let’s take a look at the main advantages of flexography.
High Speed Production
Flexo printing is fast. Presses manufactured in 2000 to 2002 for the packaging printing industry could manage an average speed of 150 to 300 ft./m (FPM), with 400 FPM being an acceptable norm. Modern Flexo presses have increased this capacity to over 600 FPM, giving a big advantage to businesses that have chosen to invest in more recent equipment. The use of rotary print heads also makes it possible to print continuous patterns, an innovation that allows printers to complete complex designs in a single print run.
Very Economic for Medium & High Volume Production
Despite great advances in digital printing, digital is still expensive and comparatively slow for medium and high volume print runs. For the many clients who still require medium to large volume print runs, especially in the label business, flexography wins hands down and can often compete with Digital on short runs too.
One-off Cost for Plates
Detractors point to the hassle and cost of creating print plates for every flexographic print run, but this can also be viewed a different way. Once a plate is made, it can be used an indefinite number of times with no additional costs. This means that the larger the print run, the lower your cost per unit. If looked after correctly, Flexo plates can be reused many times, so that repeat orders can be printed with very few overheads. This often compares favourably with the design and setup time required for digital printing, especially on labour intensive short volume print runs.
In-Line Converting Flexibility
Cycle time is drastically reduced by the in-line converting capacity native to many modern Flexo presses. This means that most print runs can be completed in a single pass. Flexographic printers can integrate many other kinds of in-line processes too, including silk screen, hot foil, cold foil, digital print, variable data print, lamination, booklet insertion, RFID insertion, multi-layer printing, and reverse side print. It is also possible to apply primers, coatings, adhesives and varnishes in-line, cutting overall finishing time.
Possible to Use Different Types of Inks & Drying Systems
Inks and drying systems have developed in complexity and efficiency alongside flexographic print technology itself. A modern flexographic press can use a variety of water-based or solvent based inks. Efficient drying mechanisms – whether using air heaters, IR or UV Driers – can increase web speed, reduce overall energy consumption and decrease ink usage. Printers have access to a potentially limitless number of colours through easy mixing of modern inks. Precise and repeatable colour formulas can be created that retain faithful consistency even when used on multiple substrates, e.g. company brand colours used on labels, food packaging and textiles.
Key Components of Napkin Flexo Printing Machine
As well as following a broadly similar process, all flexographic printing presses have a similar suite of components. These are:understanding
Feed & Unwind Station
Control of the substrate is essential, feeding it into the press at a pre-defined tension , constantly even as the diameter of the roll changes . The unwind system should have automatic web guides and options for web cleaning and Corona treaters for synthetic substrates.
Printing station
The print station needs to provide a smooth & stable drive to ensure the printed image is clean & vibration free. The basic Flexo systems includes an Ink storage tank , one or more fountain/metering rolls , Anilox Roll & Plate Cylinder . As we saw above, The ink is picked up from the tank by the metering roll which wets the anilox Roll and then ink transferred to the plate cylinder which holds the printing plates, and then onto the impression cylinder which carries they substrate, the image is transferred from the plate to the substrate before repeating the continuous process. Together, the two cylinders are sometimes known as the print anvil.
Drying Station
Each colour should be dry before the next is applied to the substrate. The drying section might include a combination of Infrared & Air drying or UV / LED curing or both systems. Better machines will ensure the drying intensity is matched to the press speed which can be variable with different applications.
Chilling Rollers
With a growing use of ever thinner synthetic and unsupported films there is a need to control the web temperature to ensure the substrate remains stable through the press. This is even more critical where using UV drying system which inherently create a lot of heat . The addition of chill rollers provide that control.
Die Cutting & Converting
These are more commonly found on narrow web presses for production of labels, tickets & cartons. Products can be cut, creased, Foiled, Stamped, Embossed, perforated all in line in the same operation as printing. Therefore producing the finished product or label in roll or sheet form. Die cutting modules need to be built with heavy duty components for the high levels of pressure/force required to convert flexible webs up to 300gsm.
Outfeed and Rewind
The output section maintains tension as the substrate leaves the printing press, by means of tension control sensors. Waste products are rewound out of the system and the final products are rewound into large rolls for later inspection.
While purchasing a flexo printing machine is undoubtedly a significant investment, there is no need to be concerned. You’ll be running those presses hot in no time if you know what to look for and how to pair your new machine with other flexo printing equipment. This will go over some pointers to help you stay on track while looking for a good flexo printing machine.
The first consideration is the type of substrate you’ll be printing on. Printers can use flexo to:
●Foil and film
●Tissue and non-woven material
●Corrugated material
●Blister packs
Not all presses are compatible with all substrates, so choose wisely. Even if your company does not currently print on these substrates, you should consider whether the machine you’re considering is capable of doing so. Who knows? Maybe you’ll decide to expand your product lines in the future.
When researching flexo printing machines, keep the following four main criteria in mind at all times:
●Operation
●Functionality
●Quality
●Cost
Ascertain that your company is prepared for the new flexo machine. Will you need a bigger workspace to accommodate the new flexo printing machine? Additionally, do you plan to provide training for your existing staff or recruit new employees?
When deciding on a flexo press, considering the manufacturing process can be beneficial. Will this new machine help you speed up your current manufacturing process?
Will you have to change your plans to accommodate it? While these may not appear to be significant considerations, they may make a significant difference in the setup cost.
Flexo printing machines, like automobiles, can be outfitted with a variety of extra features to improve functionality. Depending on your company’s requirements, you might want to consider a machine that:
●A conveyor system
●Extra drying system
●Web cleaner
●Automated inking systems
When evaluating different potential features, consider not only what your business needs now but also what your needs will be in a few years. Will your company require additional flexo printing features in five years? When it comes to flexo printing machines, don’t settle for the bare minimum; extra features may make your printing process more efficient and save you money in the long run.
