Anti-static precautions for piezoelectric ECO solvent printers in winter

As a large-width color inkjet printing device, piezoelectric photo machine must pay attention to anti-static operation in daily printing output work, providing better printing environment for Eco solvent printer.

Static electricity will interfere the normal use of the photographic machine, presumably, this is very clear to everyone, especially in the cold and low-temperature dry winter, the generation of static electricity is very common, at the same time, the machine in the normal inkjet printing work, anti-static work cannot be ignored.

Winter cold and dry at low temperature environment, pictorial machine running at high speed under the condition of easy to produce large amounts of static electricity, because the car frame and guide the friction, combined with related paper medium material in a dry environment also prone to static electricity, especially in the use of plastic base material, such as the medium such as PP, lamination, also can produce a large number of static electricity. Especially when the machine is running at high speed, the generation of static electricity will be promoted. For example, static electricity can interfere with the sprinkler head, resulting in the color chaos of the pictorial machine printing screen, unknown failures such as flying ink, spinning ink and other inkjet printing, which will directly damage the sprinkler head or even the board card, so the work of eliminating static electricity must be done well.

Eliminate static electricity and the anti-static operation of photo machine, can be for the photo machine grounding, photo machine connected to the ground line, for example, Shanghai weir complete series of photo machine is installed grounding line connecting line, can extend the grounding line for the operation. For example, the place of the grounding line on the equipment should be the place of the machine body metal closest to the main board, not too far, or some other special circumstances. Besides, during the connection process, it is better to keep the line within 3-5 meters. Otherwise, it will have a great impact on our actual use. When connected to the underground, it is better to control the depth at 1.5-2m, and some salt water can be sprayed around it.

In addition, photo machine anti-static operation can also adjust the humidity of the working environment of photo machine to avoid indoor environment too dry methods such as processing. There are also some static effects that can be avoided in the process of operation, such as touching the related electronic components with hands, etc. Please pay attention to these, and do not ignore the impact of static electricity on the machine.

UV printer ink the cause and the solution

In the US the UV printer, the most headache problem is the print pattern is a misting problem, my professional personnel all know, universal printing products are high precision products if at the time of print misting problems can cause printing products not ideal, affecting printing effect. The biggest headache for us in this situation is that while bringing losses to ourselves, it often leads to customers’ trust in us. Therefore, the urgent need to solve the UV printer’s flying ink problem is imperative. WER has sorted out five common causes and corresponding solutions for UV universal flat-panel printers flying ink.

Reason 1: the distance between the UV printer’s sprinkler head and the substrate is too high and the reasonable height is generally below 15cm. The spray force of different sprinkler heads is between 1mm-10mm from the substrate. If the sprinkler head beyond the scope of its own spray will cause the phenomenon of flying ink.Solution: reduce the distance between the sprinkler head and substrate.

Reason 2: UV printer equipment spray head break solution: print test bar, check the status of the sprinkler head, such as the detection of blockage, voids, etc., need to clean the channel of the sprinkler head, so that it remains unobstructed.

Reason 3: the voltage of the UV printer sprinkler head is too high. If this is the case, the voltage of the nozzle needs to be reduced. Solution: if the circuit board is modified, the circuit can be changed.

Reason 4: printer electronic control system electronic control system control sprinkler ignition pulse spacing is unreasonable.Solution: technical personnel is needed to solve the problem.

Reason 5: when the static electricity environment is dry and the humidity is low during the printing process, it is easy to generate static electricity, resulting in the electrostatic influence between the sprinkler head and the material.Solution: add ground wire and static electric rod.

Along with the technological innovation and progress of the whole industry, the application of UV printers is more and more extensive, which is also recognized by more enterprises. For example, the ink-flying problem of UV printers in the printing process will cause great disturbance to the production efficiency. Once this problem occurs, the ink-flying problem of UV printers should be solved in time to bring higher efficiency to the production of enterprises and create value far beyond the equipment itself.

Solvent Printing vs UV Printing

Understanding: Solvent vs UV printing
UV printing is the current buzzword of the printing industry. Many have heard the term but few consumers know what it entails. Below you will find an introduction to the differences between older solvent-based technology and the current UV systems now available.

Inkjet printing, desktop publishing and large format prints – have previously used solvent-based technology to adhere ink to substrate. The process entails mixing pigment and a solvent to create liquid ink. The printer head then transfers the liquid onto a substrate, as the solvent evaporates a hard layer of ink remains. In principle, watercolor paint works the same way. While water used to dissolve paints is harmless industrial solvents for printing are extremely toxic. To ensure the safety of employees and customers at a printing facility, complex ventilation systems must be installed to remove and capture hazardous airborne chemicals.

UV stands for Ultra Violet. The inks in UV printing do not dry but are cured by intense blast of ultra violet light. Many times more powerful than sunlight, UV lamps move back and forth with every pass of the printer head instantaneously fixing the printed image. By removing solvents from the process, virtually all dangers for the operator are removed with the exception of accidental sunburn :).

As printing technology evolves UV printing is fast becoming the new industry standard. Because there are no solvents used this system produces no dangerous VOC’s (Volatile Organic Compounds), requires no ventilation, has a higher percentage of recyclable content, and cuts cost because of reduced drying time. WER-China has currently many models of UV printing machines. To learn more about the eco-friendly aspects with UV printing, please contact our sales 008615021963625.

Differences in quality for UV and solvent processes are also important to consider. Research and Development for new technology now revolves almost exclusively around UV printers. Older solvent machines have reached their technological pinnacle as the rearguard passes them by. UV technology offers sharper images, greater detail, wider color ranges, faster and safer printing. On every front UV technology is matching and in many accounts surpassing existing technology.

How do wide format dye sublimation printers work?

Step 1 – Prepare Your Design
RIP your digital print pattern, and get it to prepare for printing.

Step 2 – Printing
Print mirrored reflection of the digital file on specially transfer paper. Your print appears when the printhead passes right to left and back again across the paper, laying the ink on the paper in layers through several passes.

Step 3 – Heater Transfer
Printed transfer paper is then transferred onto any polyester-based fabric under extreme high heat and heavy pressure using heat transfer machine.

How to do vertical line printing on pictorial machine

The printing vertical and vertical line of ECO machine should first check the raster. It is very likely that the raster is stained or scratched, which leads to inaccurate positioning of the printing screen. At this time, the raster should be cleaned or replaced in time. In addition, in addition to cleaning and replacing the raster, you can also according to the problem, through the following ways to solve.
1. Check the height of the raster decoder from the raster. The upper edge distance of the raster decoder should be 1mm-1.5mm.
2. Wipe inside and outside the raster where the vertical fine line is located, and wipe with medical alcohol with the medical cotton.
3. The above two situations are invalid. Please replug and plug the data line of the sprinkler head, the small vehicle board and the main board.
4. The above three conditions are invalid, please replace the main board or car board.

Wide-Format Printer and Plotter Features 1 Image Quality

These printers match the best office machines with up to a 2880 x 1440 dpi (dots per inch) resolution. While basic models paint the image with four or five inks, others can print with up to a dozen different colors and emulate Pantone standard colors.
Most use a combination of long-lasting pigment-based and vibrant dye-based inks. There are also wide-format printers that rely on latex inks (for outdoor use) or dye-sublimation technology (for photo-quality output).
One big difference with more pedestrian printers is that wide-format models can print on several stocks, including plain or bond paper, a clear film for backlit advertising, and polypropylene and vinyl stock for outdoor installations. You can print huge photos on matte or glossy photo stock, or even print on fabrics with many of these printers.
The distinction that scientific and engineering wide-format plotters produce monochrome prints while graphics-oriented models use color is quickly disappearing. This is a result of lower prices for general-purpose wide printers and the increasing use of color in technical drawings, such as for highlighting areas of concern or including 3D renderings.

Software
Most of these printers use Maintop or Photo-Print and other popular printer languages, including an Office or Adobe plugin so you can upsize any document or image created at your desk for large-format printing. Some have apps for giving permission and accounting for the printer’s use so it can be charged to budgets or departments.
Be aware that some manufacturers require you to pay extra for software that enables some of these extra features if you want them. For instance, it’s not unusual for the automated workflow to be an optional extra.

The Steps for Printing with DTG

Step 1  Preparing Your Shirt To Print With DTG

Think of Pretreatment like adding a primer before you paint. It helps the ink adhere better to the t-shirt or another garment, as well as to things like canvas, denim jeans, and more. We usually only use pretreatment on dark garments or non-textiles so the white ink bonds properly and lasts wash after wash. You CAN print without pretreatment, but it negatively impacts the vividness of the print and the wash-ability, so it’s almost never done.

Step2  Creating Your Graphics

All garment embellishments have to start somewhere. With direct to garment printing, the work generally begins at the computer. All DTG’s need good, clean artwork to produce the best prints on your garments. Good artwork starts with professional quality graphics software like CorelDRAW, Photoshop or Adobe Illustrator. Of course, the quality of the image you start with makes a big impact on the end result.

Step3  Printing on a DTG Printer

Direct to garment printers generally require a specialized software package called a Raster Image Processor (RIP) to print properly. Primarily, the RIP is simply a printing utility that translates the image you created into a format that allows you the most control over the end result.

Step4  Finishing your Garment

Once your printer is done printing the shirt you will need to cure the garment to set the inks to ensure maximum wash-ability.
Typical cure times range from 2-3 minutes at 340 degrees, some garments may allow you to cure at slightly higher temperatures for shorter periods of time – but you will need to test them individually – remember – the way a shirt washes will often impact future sales!

You will learn in your DTG training about different finishes you can get on your prints based on the type of curing sheet you use – Teflon, parchment, release sheets, even embroidery backing material will all give different results.
The key hardware decision in this part of the process in which heat press you select for your business.
