What should I pay attention to when purchasing a handheld printer?

Many customers want to buy the cheapest inkjet printer. This kind of psychology is understandable as a consumer, but there are many risks and problems in buying a very cheap, especially hand-held coding opportunities that are significantly lower than the average market price. It also requires us to anticipate and think ahead of time! Today, Rad Dejie will share with you what you need to pay attention to when purchasing a handheld printer. (There are eggs at the end of the article)   First, pay attention to the printing distance required by the product. Handheld printers have been in the Chinese domestic market for many years, and the reason why they have not been developed is largely due to the limitations of their use of marking products. Many customers believe that this new type of equipment is advanced and widely used. This view is one-sided. Handheld inkjet printers have been in existence for many years. Why is it not developed and promoted? The biggest reason is that it has very obvious limitations. The working principle is very similar to that of high-resolution inkjet printers. Need to be close to the product. Only the architecture is different, from the computer program connection control to the handheld touch screen control, the nozzles are the same, usually using HP ink cartridges (TIJ thermal foaming coding technology), the printing distance is required within 5mm, if the surface is not met For flat products, the printing effect will be greatly reduced, and the aesthetics and clarity will not reach the level of close-range printing. This characteristic limits the scope of its use to a certain extent, because many factory workshops have lines, products to the nozzles. Distance or request will not be within 5mm.   Second, pay attention to the drying speed and adhesion of the coded content. For the material of the product, the surface is permeable. In the daily application of the handheld printer, it is very important. The slow-drying hand-held ink cartridges generally have a drying speed of about 10 seconds (permeability materials such as paper and corrugated boxes). Except for), the quick-drying type of ink cartridges generally have a drying speed of about 5 seconds. The common problem from HP HP ink cartridges, ink drying speed and stability of use has always been a contradiction. It is also a problem that users who use handheld printers have to face. The main reason is the type of ink and the machine. The basic hardware configuration restrictions such as the pressure pump, the user must be cautious in the selection, it is best to have a real machine for on-site testing, not just to see the proofing effect decided to buy a handheld printer. Drying too fast will affect the normal coding of the nozzle, pause for a few tens of seconds or a few minutes without printing, and then it is very unclear. 128 nozzle holes are very easy to have slight or severe blockage, which directly affects the coding. Print quality. Slow drying will help stability, but on some surface materials with poor permeability, it will not dry for a long time, and the hand or product will migrate with the product and rub, pollute the product or the environment. Hand-held inkjet printers are more suitable for planarization products, and the distance between the nozzles and the products needs to be very close, which makes us a lot of irregular products or some products with uneven surface, can not form a clear coding effect, and look good The sample will be greatly discounted.   Third, pay attention to the reserve of consumables and the pre-purchasing of ink cartridges. A standard handheld printer is equipped with a cartridge capacity of 42 ml. If it is calculated according to the 3-line content (printing date, batch number, etc.), generally one cartridge can print about 50,000 pieces of information (if printing) If the information parameter is set, for example, if the resolution DPI is set to 300 or more, the number of printed information will be less. Consumables are also required to be reserved in advance, including synchronizers, batteries, transmission belts, etc. In the event of problems with these components, if we have reserves, we can let the machine resume work quickly. If not, we need to send the courier by factory. Will delay a lot of time. Because the handheld is using HP HP ink cartridges, the content of the single-jet printing information can only reach 12.7mm, which will result in some large-size content being unable to be coded. If you want to print large-format content, you can only select multiple nozzles. With splicing, the procurement cost will be greatly increased, and the ink usage will be doubled. Low procurement costs and high cost of use are a real problem that handhelds cannot escape. On the surface, handheld printers do not require solvents, which can save customers, users, and factory floors. In fact, the ink capacity of handheld devices is very small, often only a few tens of milliliters, and even 500 small print machines. 1000ML ml is a far cry from the previous one, and the cost of later use and maintenance is high.   From the above description, we can easily see that these three factors need to be prioritized when selecting and purchasing handheld printers. From these points, we can determine whether we need such a handheld code. machine.



Application Of Coding Machines In Various Industries

Nowadays, the application of identification technology is gradually deepening into every corner, especially in industrial applications, and the complexity of application is greatly increased, making the identification an indispensable part of the production in various industries. The reasons why manufacturers identify their products are as follows. 1) Conducive to product identification. By labeling the product with special logos, brand names and trademark patterns, the products can stand out from the competition and increase the brand's popularity. 2) The need for product tracking records. The batch code, shift or production date of the product is directly printed on the product, so that each product has good traceability, which greatly facilitates the quality management of the enterprise and the regional management of the product. 3) Prevent counterfeiting. Manufacturers can often prevent and suppress counterfeiting by identifying products, and the application of new technologies enables those legitimate manufacturers to stay ahead of counterfeiters. 4) Increase the added value of the product. Marking a trademark or manufacturer's name on a plastic pipe means a commitment that consumers generally consider to be a product of a company with a consistent quality tracking and product quality. 5) Improve production efficiency and reduce production costs. Different industries, inkjet printers are used in many industries such as food, beverage, building materials, wire and cable, medicine, chemical, electronics, etc. Therefore, it is important to choose the most suitable printer for the product category: 1) Small character inkjet printer: It can be used in almost all industries and has a wide range of uses, accounting for 80% of the market. Unsuitable types: silicone rubber, Teflon, etc. 2) High-resolution inkjet printer: also known as high-definition inkjet printer, also known as DOD inkjet printer. Suitable for a few industries such as plastic pipes and cartons. The high-resolution inkjet printer is mainly used for barcode printing, and the high resolution can be carried with a database, and the barcode printing can be performed. 3) Hand-held inkjet printer: It is suitable for large-sized goods such as plates and cartons and products without fixed production lines. The main feature is that it is convenient to carry out marking printing by hand. Disadvantages: the position of printing is not fixed, the appearance is not so unify or perfect. 4) Laser jet printer: It is suitable for almost all industries. For the wine industry, the temperature of the hot filling line is very high, and the inkjet printer is not suitable. It can only be printed by laser jet printer. However, when using a laser printer to print, the surface of the product will be damaged, so the user should carefully consider when making the selection.



The Daily Maintenance of Inkjet Printer

The Daily Maintenance of Inkjet Printer Inkjet printer is a precision equipment. If the daily maintenance is not timely and accurate ,various faults will occur easily, bringing a lot of inconvenience in production. Therefore, the daily maintenance of inkjet printer is very important.The special person is needed for maintenance to ensure the work well in the production. We summed up the daily maintenance of inkjet printer for your reference in order to extend the inkjet printer lifespan and improve equipment working efficiency as well as reduce faults.   1、Inkjet printer regular inspection and maintenance   Check the level of ink and solvent every day.The ink or solvent should be added timely when the liquid level is too low. When adding ink it should not be too full.Or else, it’s easy to precipitate ,which not only wastes supplies also affects the print quality.   Check the ink viscosity every day,which is very important for the stable running of the printer. If the ink viscosity is high,which easily cause the main pump load increasing leading to motor diaphragm damaged; If ink viscosity is low, which easily leads to high-speed rotation of the pressure pump .Meanwhile,long-term high-speed rotation will reduce the pump lifespan! Besides,if the difference of the actual ink viscosity and set value is too large ,it will also affect the product's print quality. Therefore, we must ensure that the ink viscosity is normal.   Please clean and dry printhead before the printer starts work every day.Printhead is a key part of the printer.If the nozzle is too dirty,which will result in imnormal ink charging , big changes of voltage on deflection board and it will directly affect the print quality. Therefore we should clean the printhead immediately when it is too dirty and dry it with the hair dryer after washing.   Should clean the environment around the inkjet printer, in particular the printer crate and keep it clean to ensure that there is no ink stains on the crate in case caing corrosion. Clean the used solvent bottles and scrubbed shredded pieces.   Clean the filter and check the fan every week to prevent dust from entering the circuit system. Regular clean the air filter regularly can effectively make the air flow smoothly, to ensure that the circuit system temperature is maintained at room temperature. The fan is also a prerequisite for maintaining room temperature in the electronic system box.   Should be replaced the main filter regularly which is the important maintenance of inkjet printer content, because the ink impurity accumulation, easily to cause instability operation of inkjet printer, importantly because the filter plug, will seriously affect the life of the pressure pump, replacement of the filter regularly, will greatly extend the life of the pressure pump.   2、If the inkjet printer doesn’t work for a long time   No matter how long you keep the machine power supply off every time ,as long as the inkjet printer runs 2-3 times every week and you keep the ink line running for an hour every time, so you may use several times of short stops instead of prolonged downtime.   If the machine doesn’t start for 3 days, the nozzle will be blocked normally, especially anti-migration black ink printer.In this case the nozzle should be removed for cleaning If the machine does not use for a long time (for example 10 days),the ink should be released and added into the solvent for maintenance,especially for the white inkjet printer.You see, it will cause the ink precipitation, causing serious damage to the machine because of a long time non-working.     3、The handling and placement of inkjet printer   In principle, each production line can only be placed on one printer, if production required, can be placed in a different ink color inkjet printer. Do not place more than two machines.   If the Inkjet printer has any problem , should contact the maintenance staff and solve it immediately . Can not arbitrarily carry the machine on other production lines。 When the machine is failed in evening but no staff on duty ,should move the machine to repairing room and note about it .dont put the damaged machine in workshop   In the handling of inkjet printer, should pay attention to gently.   4、The the use and custody of Consumables Consumable is volatile, when store, should be less than 35 degrees, to avoid high temperature, away from fire, heat, must be well sealed and stored in a well ventilated place (closed good thick-walled iron storage).   Inkjet printer strictly corresponds to the consumption of brand and model use, shall not use alternatives, otherwise it will cause serious harm to the equipment.   When the solvent splashed into the eyes, immediately with plenty of water to clean the eye.   5、Regular training   Regular training for the operators, Only by constantly improving the operating skills to make the machine to achieve the best condition, but also to reduce unnecessary waste and product defects.   The Inkjet printer has a certain life, must be careful in daily use, attention to detail,pay attention to maintenance.    



The difference between inkjet printer and laser marking machine

Ink jet printers and laser printers are now popular inkjet devices, which are widely used in daily processing, but there are some differences between them, so let us introduce you.   1. Both have anti-counterfeiting effects Laser marking machine: The printing information is directly engraved on the surface of the product. The marking can be lined and dot matrix. The visual effect of the marking is unique, the marking is clear and permanent, and it can not be erased and changed, and the anti-counterfeiting effect is obvious. The inkjet printer: the marking effect is clear, but easy to erase and change. Generally, the inkjet printer has limited anti-counterfeiting effect. Now, the newly introduced invisible ink has better anti-counterfeiting effect, and has the characteristics of being difficult to find and good concealing.   2. Working status The laser marking machine adopts online high-speed non-stop laser marking, which has high production efficiency. It can work statically and at high speed in the production line. The ink jet printer is more suitable for online use, with no pauses in production and high production efficiency. Some printers may have ink clogging nozzles that affect production. Most of the customers use both inkjet printers and laser printers, so the two coding devices are complementary.   3. Flexibility Laser Marking Machine: Printed content can include serial numbers, lot numbers, barcodes, QR codes, logos and patterns. The number of print lines and font size are not limited. Inkjet printer: barcodes, lot numbers and simple patterns can be used, and the number of print lines and font size are limited. The laser marking opportunity is affected by the material, and the application and adaptation of the inkjet printer are stronger.   4. Reliability Laser marking machine: stable and reliable performance, continuous operation all day. Maintenance-free time is up to 20,000 hours. Inkjet printer: Performance is basically stable, but the failure rate is relatively high. The nozzle will be blocked due to changes in ambient temperature and humidity and dust. The maintenance workload is large and is greatly affected by the environment. In terms of equipment reliability, the laser marking machine is slightly better.   5. Operation and use Laser marking machine: Intuitive window software (WindowsXP), the display interface has high resolution and clear picture. Make the creation and editing of print information convenient and fast. Inkjet printer: simple display interface and low resolution. The print information can only be easily edited and used as a production date printing device.   6. Initial cost Laser marking machine: The one-time purchase price is higher, and the later use cost is lower. Inkjet printer: The one-time purchase price is lower, but the inkjet printer consumables are a long-term use cost, and the maintenance cost and maintenance cost are not cheap.   7. Operating costs Laser marking machine: The operating cost is extremely low, and no planned production stoppage is eliminated. The equipment can be operated free of maintenance for a long time without any consumables and zero operating costs. Inkjet printer: The printer consumes a large amount of special inks and solvents, and the amount of consumables is large. In addition, the replacement of nozzles and other accessories is expensive, requires special maintenance personnel, and will stop production without any plans, resulting in indirect losses. The cost of consumables for a printer is between 0.5 and 20,000.   8. Data processing capabilities Laser marking machine: The control host directly adopts the industrial control computer, which has powerful data processing capability and can connect all anti-counterfeiting data systems to meet the multi-level anti-counterfeiting requirements. Inkjet printer: It adopts single-chip control, limited data processing capability and few anti-counterfeiting functions.   9. Environmental protection and safety Laser marking machine: It is an environmentally-friendly high-tech product that does not produce any substances harmful to the environment and the human body, and produces surface marks on objects to be printed. It has been widely used in the production of food and medicine. Meet the GB7247-87; GB10320-88 standard. However, its laser engraving produces smoke and can generally be treated with a smoke evacuation system. Inkjet printer: Ink and solvent are highly volatile substances, which will produce more chemical and toxic residues and pollute the environment. In addition, the chemical composition and odor of the ink and solvent are completely infiltrated into the marked object, and it is an internationally gradually replaced product.   Of course, the above is only for the comparison of the characteristics of the two coding solutions, each has its own advantages and disadvantages. There is no best coding equipment, only the most suitable coding solution. Don't aim at demand, and don't adjust to the local conditions, consumers will only increase their own production costs. Radi Dejie, give you a professional coding solution.



What kind of inkjet material is better for the material of the plastic material?

Now most of the bags are made of plastic, but the plastics are also classified. Different types of plastics use different inkjet printers to produce better results. Leadjet will give you an analysis of which plastic materials use which type of printer is better.   PP: Polypropylene. It is a semi-crystalline thermoplastic plastic with high impact resistance, strong mechanical properties, resistance to various organic solvents and acid-base corrosion, and is widely used in industry. This kind of material belongs to common polymer materials. The UV ultraviolet laser printer is better. The UV laser printer is cold-processed. It can change the molecular structure of the surface of the material through the purple light of 355 nm wavelength, leaving a permanent mark and greener. Environmentally friendly and efficient. OPP: oriented polypropylene. The white point is a plastic bag, characterized by easy burning and softness. It is recommended to use a thermal transfer printer to print. The thermal transfer printer can achieve high-speed coding, and the effect is beautiful. It is very suitable for high-efficiency printing of plastic bags. In particular, it can be equipped with some rewinding and unwinding machines to achieve high-speed online assignment. The other is that the resolution is relatively high. If the variable two-dimensional code is printed, there will be a very good scanning recognition rate. PET: Polyterephthalic plastic. PET is the abbreviation of English Polyethylene terephthalate, referred to as PET or PETE. Common in mineral water bottles, carbonated beverage bottles, etc., has now developed into the current beer bottles, edible oil bottles, condiment bottles. Pharmaceutical products, cosmetic bottles, etc., suitable for the coding equipment are small character inkjet printers and ultraviolet laser printers, widely used for small character inkjet printers. ABS: acrylonitrile-butadiene-styrene copolymer. ABS resin is one of the five synthetic resins with impact resistance, heat resistance, low temperature resistance and chemical resistance. The electrical performance is excellent, and it has the characteristics of suitable processing, stable product size, good surface gloss, etc. It is easy to be coated and colored, and can also be subjected to secondary processing such as surface metallization, electroplating, welding, hot pressing and bonding. Widely used in machinery, automotive, electronic appliances, instrumentation, textile and construction industries, it is a very versatile thermoplastic engineering plastic. This kind of material uses laser jet printer to code more, because the application industry is different, so what type of laser printer is needed to carry out on-site proofing, compare the effect to judge. PVC: Polyvinyl chloride. It is a white powder with a fixed structure, the degree of branching is small, the relative density is about 1.4, the glass transition temperature is 77---90 °C, and the decomposition starts at about 170 °C. The stability to light and heat is poor, above 100 °C or over a long period of time. When exposed to sunlight, it will decompose to produce hydrogen chloride, and further autocatalyze decomposition, causing discoloration, and physical and mechanical properties are also rapidly declining. In practical applications, stabilizers must be added to improve the stability to heat and light. PVC material is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wire and cable, packaging film, bottles, foam materials, sealing materials, fibers and other aspects. These industries use a large number of inkjet printers. When selecting a printer to print, it is still necessary to perform proofing analysis on the product and select a better inkjet printer. More material knowledge and coding identification industry application materials, please call Rad Dejie or leave a message on the public number, we will have more professional technical engineers, customer service to answer your questions, help you quickly choose more suitable from all kinds of equipment The coding equipment realizes efficient coding and enhances the high-speed and efficient completion of the coding process in the production process of the factory.
