Flexo Printing or Offset Printing?

Although both methods use wet ink and printing plates, these two printing processes are quite different. Technically, offset printing can refer to any printing technique that uses a printing plate to transfer an image to an intermediate carrier and then onto the printed substrate. Whereas flexo transfers ink from the plate directly to the substrate.


Flexo and offset are both popular, but they perform their tasks differently. It is important to understand what roles they perform and have a clear understanding of both types of printing process. The type of printing press to use depends on the final product and quality required, as well as volumes and substrates.


Difference 1: Plates

As the name suggests, flexo printing utilizes flexible plates for a rotary printing process. The plates are made from a photopolymer compound and are flexible enough to be wrapped around a printing cylinder. The relief image on the plate is fixed via a laser image-setter and the polymer in the ‘non-print’ areas is washed away in a processing unit, where it is dissolved into a solvent or water solution. Ink is transferred from the ink well via a rotating ‘anilox’ roller onto the flexo plate. A separate printing station & flexo plate is required for each color to be printed. The image is then printed directly onto the substrate. The printing plates are quite durable and if stored correctly, can be re-used several times, before they eventually need to be replaced.


For offset printing, again as the name suggests, ink is transferred (offset) via a series of rollers onto the printing plate. This can be either a flat-bed or rotary process – depending on the type of offset press. The plate is usually made of aluminum. The complete wet image (either single color or multicolor) is then transferred onto a ‘blanket’ and in turn onto the substrate, before drying.


Difference 2: Ink

Offset printing usually consists of four ‘process’ colors; cyan, magenta, yellow and key (which is black). Each color has a dedicated printing station. Any spot colors are made from a combination of the process colors. Ink can be water based or UV curable.


Although process colors are also used in the flexo process, additional print stations tend to be used for spot colors. Spot colors can be supplied pre-mixed, or can be mixed in-house, as required. Flexo inks can also be water-based or UV curable. Solvent based inks can also be used. UV inks enable higher running speeds and can be left in the press at the end of the day, without the need to empty & clean each print station.  Water based inks need to be removed from the press, when it is not in use – to prevent ink from drying on the rollers & in the ink trays.


Difference 3: Types of Materials To Print On

Offset printing machines can print on materials such as; paper, metal, cardboard, cellophane and vinyl. The printing surface must be flat and smooth. It is excellent for printing newspapers, books, magazines, stationery, posters, brochures and so on. Generally, to print onto both sides of the substrate will require a second pass. Similarly, any die-cutting, slitting, folding, creasing, laminating, etc is done as a secondary, off-line process.


Flexography is used on both absorbent and non-absorbent materials, for example, cellophane, foil, cardboard, fabric, plastic, metal etc. It is mostly used for packaging; envelopes, retail bags, wallpaper, paper, newspapers, sweet wrappers, labelstock and so on. The main difference with both processes is that offset printing is only done on flat surface while Flexographic printing can be used on almost any substrate with a flexible surface. Flexo printing can achieve high speed production and many presses have multiple converting options integrated into the press, enabling a single pass operation.


Making The Right Choice

Both flexo machine and offset machines have their advantages. Flexography is excellent for high speed production and overall quality. It is great in efficiency in many ways and is generally appropriate for most large-scale printing tasks. In the label printing sector, most businesses prefer flexographic printing because of its adaptability and economy of scale. When looking for a printing solution, look for one with the future in mind, and invest in the printing technology of the future. One current trend for flexo is for it to be combined with digital printing technology to produce powerful hybrid solutions that outperform most traditional offset presses.


Flexography beats offset printing in many circumstances because of its flexibility & productivity benefits. A flexographic press machine is a sound, long term investment and is adaptable enough to accommodate and integrate a wide range of in-line processes, including new digital technology.

Pruning garden plants makes them look more attractive, but it also can increase the health and productivity of flowering or fruiting shrubs. When it comes to doing the pruning work, you’ll get a better result if you use the optimal tool to accomplish each part of the job. One important gardening tool is called a pruning saw. If you’ve never used one, you may have lots of questions. What is a pruning saw? What are pruning saws used for? When to use pruning saws? Read on for all the information you need to get started using a pruning saw.


What is a Pruning Saw?

K&W Pruning Saw
So exactly what is a pruning saw? Before you begin using a pruning saw, you’ll want to be able to find one in the toolbox. A pruning saw is a tool with the same sharp teeth as saws used for cutting lumber. But pruning saws are intended for trimming live shrubs and trees. There are many types of pruning saws, each intended for a particular type of branch or stem. All types of pruning saws should have hard-point, heat-treated teeth, but they come in different sizes and shapes. Using a pruning saw that matches the task at hand makes it easier to do a good job. What are pruning saws used for? They are intended to help you trim larger shrubs and smaller tree branches. If you are wondering when to use pruning saws, here’s a good rule of thumb. If the branch or trunk you want to trim is under 1.5 inches (3.81 cm.) in diameter, consider a hand pruner. If the wood is that thick or thicker, it is prudent to use a pruning saw.


What are Different Types of Pruning Saws?


Pruning saws come is different sizes and types. Be sure you are using pruning saws that best match the job you are tackling. For branches that are too thick for hand pruners, use a pruning limb saw. If the branch to be pruned is in a tight area, use a pruning limb saw with a shorter blade. Select a finely-toothed, curved pruning saw for branches up to 2 ½ inches (6.35 cm.) in diameter. Try using a pruning saw with coarse teeth for heavier branches. High branches require a special type of tool called a tree pruning pole saw. These tools usually have a pole as tall as the gardener using it. Expect a sawblade on one side and a curved blade on the other. The curved blade gets hooked over the branch to be trimmed. If you need to carry a pruning saw for trimming a tree, select one that has a blade that folds into the handle. This makes it easier and safer to use when you are taking it up a ladder.


If you need more selection of pruning saws, I recommend you to visit K&W Tools Co., Ltd. – they are the professional gardening saws manufacturer and supplier. Get more details, welcome to check out their website and feel free to contact with K&W.

Custom machine shops offer a valuable resource to businesses and individuals. Why? Because they are custom. If you need something done that many places can’t do, customization is what you need. The skilled craftsmen at machine shops use hand crafting and computer-controlled machines to fabricate replacement parts, customized designs, and perform maintenance and repair on various pieces of equipment from lawn mowers to ice houses to heavy equipment used on farms.


What is CNC? CNC refers to Computer Numerical Control, and is responsible for the automation of machine tools. The types of tools controlled by CNC processes include lathes, drill presses, and screw machines. All of these tools are used in the machining process to cut metal components to desired dimensions with a high degree of accuracy and detail. CNC milling and CNC turning have made it possible to create patterns and add detail to metal components that are not possible by hand. What are the differences between CNC milling and CNC turning?


CNC Milling


CNC milling consists of a milling machine that uses commands, or G-codes, programmed into the machine via a computer software program. Each code entered into the program has a designated function that is performed by the machine. When codes are entered into a CNC program representing a potential finished product, the mill then drills and turns along axes to cut and shape the material to match the dimensions entered into the computer.


CNC milling machines are controlled in one of two ways: by computer or via manual override. Computer programming allows the machine to make the precise cuts required, but the manual override allows a CNC machine operator to slow down or speed up or tweak the process if necessary.


There are numerous examples of products that can be created using CNC milling processes including pulleys, arms, linkages, fixtures, and valves. Often customers have a need to make a strong part from aluminum or steel to replace a weak plastic part supplied by the manufacturer, and CNC milling machines can do this.


CNC Turning


Turning is a slightly different process compared to CNC milling. CNC turning relies upon computer-controlled machines, but creates a different end product. The process uses a single-point cutting tool that is inserted parallel to the material that will be cut. The material (metal, plastic, etc.) is rotated at varying speeds and the cutting tool traverses the 2 axis of motion to produce cylindrical cuts with exact depths and diameters.


CNC turning can be used on the outside of material to create a tubular shape, such as a decorative brass shoulder bolt or nautical drive shaft, or it can be used on the inside of material to create a tubular cavity within the chosen material. Just like CNC milling, CNC turning is now an automated process because it can complete projects faster and with greater accuracy than turning a lathe by hand.


As mentioned, CNC turning is used to create objects with round or tubular shapes that are created from larger pieces of material. A drive shaft is a simple example of an object that could be created using CNC turning. Other examples include tubing and custom couplings for plumbing or other applications.

Lining Fabrics for Clothing

On November 6, 2018, in Fabrics, Manufacturer, by Jasmie K.

Lining fabric refers to a group of materials inserted into various garments, from skirts and shorts to dresses, jackets and coats. Such fabrics can be made of natural or synthetic fibers and range from sheer to opaque.


While most of them are produced in solid colors, you can still find lots of patterned lining materials. This FAQ section covers the most popular questions about lining fabrics, their types, and properties.


What Is It Used for?

The purpose of lining fabric is to make your garment more wearable, long-lasting and comfortable. They are usually lightweight and have a soft or silky texture. Not all items need to be lined, though. Here are some reasons why sewists turn to lining materials:


  • To make the garment less see-through
  • To add warmth and durability
  • To make the inside part of the garment soft and pleasant to the touch
  • To lend a luxury note to a garment
  • To improve the structure of a garment
  • To help the garment slide on easily
  • To conceal seams, padding, interfacing, etc.


When choosing the appropriate lining for a project, one needs to pay attention to the stretch factor. If the garment is not stretchy, e.g. a cotton shirt or a wool jacket, non-stretch lining fabric is ok. But if the item is made with elastic materials like jersey, tulle or stretch satin, the lining one ends up choosing should be stretchy as well.


Lining, Underlining, Interlining — What’s the Difference?

Sounds confusing, right? Actually, the puzzle is quite easy to solve! These are layers inside a garment that serve different purposes.


Lining is attached to the inner part of the garment to help keep its shape, hide the interior construction and facilitate the whole putting on/taking off thing. Interlining is added to a garment for extra warmth and insulation (some examples include fleece or flannel) and can be removable, in which case it is also called ‘a liner’. Underlining provides more body and opacity: it is cut for every pattern piece separately and attached to the wrong side of the outer fabric. Mind that the double layer material you get in this case is treated as one.



Silk, viscose, acetate, polyester and rayon are among the most popular fibers used for lining materials. In many ways, the fiber type is the key factor: it influences the way your lining feels to the touch, the way it sews and drapes, its breathability and – last but not the least – the price point. Below are the types of lining cloths available on the market:


Fiber Type Pros Cons
Natural fibers Silk lining
  • Can be soft or smooth
  • Can be sheer, semi-sheer or opaque, matt or shiny
  • Good for skin
  • Can be too hot in summer
  • Not very durable
  • Sensitive in care
  • Expensive
Cotton lining
  • Soft
  • Breathable
  • Not static
  • Good for skin
  • Machine washable
  • Not slippery
  • Wrinkles easily
  • May shrink
Wool lining
  • Warm and insulating
  • Breathable
  • Soft
  • Can be itchy
  • Too warm for summer
  • Sensitive to care
Artificial fibers Viscose and rayon lining
  • Breathable
  • Static-free
  • Silky soft
  • Drapes well
  • Not strong when wet
  • Wrinkles easily
  • Can shrink in the wash
Cupro lining
  • Smooth
  • Satiny shiny
  • Breathable
  • Static-free
  • Takes up stains easily
  • Not strong
Acetate lining
  • Less shiny than polyester
  • Breathable
  • Builds static
  • Prone to ripping and fraying
  • Wrinkles easily
  • Less absorbent
Synthetic fibers Polyester lining
  • Soft and shiny
  • Strong
  • Wrinkle-resistant
  • Cheap
  • Machine washable
  • A somewhat plastic feel
  • Can be static
  • Not breathable
  • Keeps the odours
  • Too hot for summer


Many lining fabrics are interchangeable, which means you can use various textures and compositions – it’s all up to your preferences and budget.

Discovering Taiwan’s Bubble Tea

On October 24, 2018, in Food & Drink, by Jasmie K.

Empire Eagle Bubble Tea Material Supplier
In Taiwan, where bubble tea was invented, making this beverage is much more complicated than simply adding tapioca pearls, sugar, and ice to a glass of tea. For an out-of-the-box travel excursion, take a class at the Chun Shui Tang Cultural Tea House in Taichung, a 90-minute drive outside of Taipei in central Taiwan, to learn the traditional way. You might be surprised to learn that the process is as precise and choreographed as a traditional hot tea ceremony.


First things first: Taiwanese bubble tea is traditionally made with freshly brewed Assam black tea and sugar syrup (not powder sugar), with black tapioca pearls (not white) and powdered milk (not liquid). It’s shaken in a martini shaker, not stirred in a glass, to produce a foam head reminiscent of a properly poured glass of ale or stout.

The hands-on classes are held in the tea house inside the National Museum of Fine Arts, which houses an excellent collection of Western and Chinese art. The tea house also offers traditional classes for brewing and serving green and black hot teas. Angela Liu manages the classes and has an impressive bubble tea pedigree of her own: she’s the daughter of Liu Han-Chieh, the man generally regarded as the food’s creator, whose family operates more than 30 Chun Shui Tang Culture Tea House locations in the country. They have plans to expand the stores internationally in Asia and to open a bubble tea museum in Taichung.


If you don’t quite have the time for an entire class, grabbing an order of the ever-popular drink is easy. Popular chains in Taipei, Taichung, and other cities in the country include ComeBuy, which also has several locations in the U.S.; 50 Lan (50?), one of the few locations that offer mini-boba these days; and 85°C (85?C), a popular cafe. You can also find bubble tea at independent stores, night markets, and cafes everywhere. Wherever you go, a cup will run you as little as 50NT ($1.6).


Before you step up to order, be prepared. Patrons are offered the opportunity at many stores to customize the amount of sugar and ice that goes into their drinks — you can confirm you want the usual recipe, or ask for a little, half, or no sugar or ice. If you’ve already tried the traditional drink, the alternatives are nearly endless. You can spring for green tea, have your tea flavored with passionfruit or skip the milk. Beyond tapioca pearls, toppings include grass jelly, pudding, nata de coco, and (sweet) red or green beans. There are even caffeine-free options, like wintermelon tea.


As for Taichung, there’s a lot to see beyond bubble tea. It’s Taiwan’s third largest and oldest city and is perhaps most famous for its Confucius Temple. Many of his sayings are engraved in gold leaf or carved into the wooden doorways. The temple garden is a popular spot for meditating — and you might need to, for mental strength, before negotiating the crowded and boisterous Fengjia Night Market, or to reflect after visiting the 921 Earthquake Museum, with artifacts and history of the 7.3 Richter scale tremor that rocked the island nation in 1999.


Chun Shui Tang Cultural Tea House and 50 Lan (50?) provide simple trial class. But if you want to own a bubble tea shop, I advise you must-have a professional bubble tea training course. To get a best tea shop training program, I will recommend you to take part in Empire Eagle’s JD HALL Training Program.

Keeping a wire EDM running at peak performance requires proper maintenance and the appropriate consumables for the job.


Consumables and Maintenance


In addition to wire, EDM consumables include water filters and resin, and power contacts that deliver the power to the wire.


Wire EDM maintenance should be proactive and preventive, according to Makino’s Pfluger. “You don’t want to run the EDM until you have a problem,” he said. “You want to do it at prescribed intervals so you don’t have any surprises—like having the machine stop when you are running overnight. With the wire EDM process, the name of the game is maximizing unattended machining time.” Most new machines notify the operator when maintenance must be performed.


With wire EDM filtration systems, wire EDM filters must be replaced at prescribed intervals—typically after 200 to 300 hours of operation. It can vary based on the filtration system capacity, machine operations being performed and material being machined.


A new type of filter is available made from poly fleece, a soft, two-sided pile material made from polyester. “Most filters have a paper-type element,” Pfluger said. “When you put a new set of paper filters in the machine, you have a precoat time. Say I have a new 5µm-particle-removal filter. It could be up to 10 machining hours before I am filtering my water dielectric out to a 5µm level. With the new poly fleece filters, there is a zero precoat time. You are at the defined micron rating immediately.”


Resin life depends on filter efficiency, materials being machined and quality of water that is added to the machine reservoir. “People tend to stretch their resin life by letting it run longer than it should,” said by Ken Baeszler, a product manager at GF Agie Charmilles, Lincolnshire, Ill. “But the water becomes more conductive and they don’t get the results they want.”


The two power contacts, one in the upper head and one in the lower, must be indexed occasionally and eventually replaced. Indexing intervals can vary, depending on the machine manufacturer and machining processing being performed.


“Depending on how aggressive the settings are and the wire diameter, the contacts should be indexed after 60 to 80 machining hours on average, taking into account the differences in operations and wire sizes,” Pfluger said. “If those items are not maintained, the EDM will not work at all.”


Water cleanliness is also important. The water has to be at the right pH level—from 6.8 to 7.2. “But if sensors on the wire EDM for the water are not cleaned with alcohol every 150 hours, you are going to have a bad resistivity reading,” Top Tool’s Kari said. “Also, it is important to change the water at least once a year.”


The EDM itself must also be kept clean, including the rollers that help tension the wire. Over time, dirt and debris accumulate on those rollers, which can cause slippage.


“Cleaning is critical for any EDM,” AccuteX’s Intihar said. “We recommend taking 15 minutes every Monday to clean. Remove the wire guides, power contacts and other removable parts and clean them with EDM cleaner along with the upper and lower heads. Put it all back together and you are good for another week.” CTE

When selecting a shear, many people assume that hydraulic operation is a better option as they equate it with a press brake. However, shearing is a completely different process and mechanical actuation can actually be preferable for a shear due to the following factors.


Where Mechanical Shears Excel

  • Speed: Mechanical shears are faster in full cycle mode.
  • Shock Resistant: Heavy castings and frames absorb the snap of the shearing process better than hydraulic cylinders.
  • Simplicity: Mechanical shears have simpler mechanisms to maintain and repair making up time longer and downtime shorter.
  • Noise: Mechanical shears are quieter as they do not have the constant running of hydraulics.
  • Heat: Without hydraulics mechanical shears run much cooler
  • Green: No hydraulic oil, hydraulic heat (requiring cooling), hydraulic oil waste, or filter waste.


Where Hydraulic Shears Have an Advantage

  • Variable Stroke Length: Mechanical shears must make the full cycle when shearing whereas hydraulic shears can be set to perform quick, short strokes—which is useful when shearing material that is only a few inches in width.
  • Overload Protection: Because it’s protected by a blowout valve, a hydraulic shear can stop the blade from getting into a “locked” position with the material. Basically, when the hydraulics reach the maximum PSI for the shear, a safety valve opens up and dumps the high pressure hydraulics—stopping the downward force and thus allowing the ram to be backed off and the oversize/hard/obstruction to be removed.
  • Price: Hydraulic shears are inherently cheaper to build.


Common misconceptions in shearing assume that hydraulic shears are “safer.” While hydraulic shears can be stopped in a cycled down stroke, so can a mechanically actuated system. The difference is that hydraulic shears can be automatically reversed when stopped, whereas mechanical shears cannot. When protected by proper guarding and light curtains as necessary, a mechanical or hydraulic shear can be a great addition or compliment to your fabricating process.


If you want to get more information of hydraulic shears, welcome to visit Yeh Chiun Industrial Co., Ltd. – they are the professional manufacturer of specializing in high-quality press brakes. To get more details of shearing machines, please do not hesitate to contact with Yeh Chiun.
