Printing principle of digital inkjet printer

With the introduction of large-format inkjet printers, digital inkjet printers have gradually appeared in our field of vision. Next, we will explain the printing principles of digital inkjet printers in detail. First of all, picture imaging. After setting the output method on the computer, connect the computer to the photo machine to output the image. The photo machine goes through a series of cooperation (nozzle ink, thermal transfer paper, dryer, take-up reel, etc.) to print The machine prints the drawings, and the pattern is printed on the thermal transfer paper by the ink of the photo machine. The printed image is on thermal transfer paper. Then, the printed transfer paper pattern is pressed and transferred by a roller printing machine (or heat transfer equipment) together with the fabric. This step process is transferred through high temperature (about 200 degrees), so if you don’t High temperature resistant fabrics are not suitable for the process of digital sublimation printing. In general, the sublimation digital printing process is the two major processes. The printing principle of the digital inkjet printer is one of the very important processes, and both are indispensable. Mastering these two processes is equivalent to mastering the entire operation process...

How to enhance the weather resistance of advertising screens in winter

The cracking and separation of the advertising screen is caused by the combination of environmental and climate changes, materials, ink and other factors. The cracks can be repaired by using a hair dryer. If you want to completely solve this problem, you also need to start with the printing materials, The performance of printing materials in winter can be considered from the following five aspects: good frost resistance, good fire resistance, good wind resistance, good UV resistance, good corrosion resistance, and guaranteed autumn and winter from the source The quality of the printed product. Such as: PVC materials, textiles, PE materials, etc., all have excellent low temperature resistance and good weather resistance. When used in cold winter, there will be no screen cracking or separation. Specific material handling methods Glass stickers In winter, the glass is prone to fogging during construction, or it is prone to breakage in colder climates. The main reason: the material is out of date, or the product is too cheap, there is no solution to the problem. Solution: Choose a material with strong cold resistance and recently produced material~ Adhesive products Adhesive products such as 3M light box cloth film screens are applied below zero,...

How to improve the effect of the eco solvent printer

In the process of using the eco solvent printer, how many large and small failures will be encountered, so how can we improve the effect of the piezoelectric eco solvent printer? 1. Size: The image size of the photo is the same as the actual required screen size. It is different from printing, and there is no need to leave the bleeding part. In inkjet printing companies, there are usually blank borders after the output screen. You can discuss with the advertising company how much white margin to keep for buttonholes. The price is calculated per square meter, so the screen size should be in centimeters. 2. Image resolution requirements: Photos generally require 72DPI/inch to be set. If the image is too large (for example, the file size exceeds 400M when the actual size of the new image is displayed in PHOTOSHOP), the resolution can be appropriately reduced, and the resolution can be controlled within 400M. 3. Image mode requirements: The photo uniform uses the CMKY mode, and the RGB mode is prohibited. The current piezoelectric photo printers are all dual four-color printing, and its color is completely different from the printing color. Of course, when drawing pictures, follow the...

How to solve the problem of large particles in the eco solvent printer?

When using the eco solvent printer, some users may encounter the problem of large particles in the eco solvent printer, resulting in poor picture printing quality. There are several reasons for the large particles in the eco solvent printer. Users can investigate and solve them according to the actual situation. 1. The large particles in the eco solvent printer may be caused by the clogging of the print head. The solution is to clean the print head with the machine pumping ink. 2. If there are coarse particles in a certain position in the drawing screen, this may be caused by uneven printing platform. The solution is to use special tools to adjust the printing platform. 3. The low pixels of the image source file will cause the output image to have obvious graininess. The solution is to switch to high-definition and high-pixel image source files. 4. The quality of the printing media of the eco solvent printer is poor, the material is rough, and the ink absorption is weak, which will also cause the eco solvent printer to print images with large particles. The solution is to replace it with a better printing material for testing. 5. The solution...

Application of inkjet technology for eco solvent printer

Large format printing is a broad market. Some people describe it vividly as “all indoor and outdoor application markets divided by four walls and one roof.” , Building exterior wall covering inkjet products), store promotional prints, posters, advertisements, posters, promotional materials and so on. Some reports estimate that the current global market for this application field exceeds 3.58 billion square meters, which is very large. This market is a typical market where quality and speed requirements are balanced. Generally, high resolution is not required. Most of the systems currently running are around 600dpi (of course, it can be made higher technically), and the speed is ~ average In the hundreds of square meters per hour, some are close to 1000 square meters per hour. It is said that a high-speed system of 3000 square meters per hour may appear in the near future. So far, water-based inkjet and paper-based substrates have occupied the main market share of large-format inkjet printing. However, the structure of this market is undergoing drastic changes. Water-based inkjet and paper-based substrates are Rapidly losing the market, the proportion of solvent ink jet and UV ink jet is rapidly expanding. From the perspective of environmental protection, production...

The eco solvent printer encounters these faults, Skycolor teaches you to solve it easily

In the process of using the eco solvent printer, there may be some failures of one kind or another. What are the common faults and how should these faults be solved? 1.The print head does not emit ink or the printing is broken There are several reasons for this situation: One is that there is no ink in the ink cartridge, just add ink. The second is that the nozzle is clogged. If the nozzle is slightly clogged, it can be cleaned with the cleaning function of the printer itself. If the clogging is serious, remove the nozzle and soak and clean it with cleaning fluid. The third is that other links in the ink supply line are blocked, such as ink sacs, ink supply tubes, etc. At this time, clean or replace the blocked parts. 2.Printed image is skewed The skew of the printed image of the eco solvent printer may be because the printing material is not placed flat and skewed swelling; in addition, it may be that the tension of the stepping motor in the winding system is controlled by a problem, which causes the printed image to appear skewed. 3.Misplaced print ghosting There are two reasons...

What should I do if the eco solvent printer flies and breaks when the cold wave comes?

When the temperature continues to drop, the printer will experience oblique spraying of the nozzle, flying ink, and false images when the eco solvent printer is working. In fact, this is all caused by the “temperature”. 1. The temperature of the working environment is very important to the eco solvent printer. If the temperature is too low, the eco solvent printer will have oblique spraying, flying ink, and false printing. When the user finds that the image of the test strip is false, he can use an electric fan or a hair dryer to heat up the nozzle to avoid such problems when the eco solvent printer is working. In addition, before using the eco solvent printer, the user should turn on the air conditioner or electric heating fan in advance to warm up the working environment of the eco solvent printer. So that the eco solvent printer is in the best working condition, which not only improves the working efficiency. , And the printing effect is also excellent. 2. In addition, static electricity is very easy to generate in winter, especially in air-conditioned rooms, where the air is extremely dry, which is a hotbed for generating static electricity. Excessive...
