What Factors Affect the Printing Effect of Wide Format Printers?

The color reproduction of wide format printers is one of the important signs for evaluating the quality of prints, just like the tone reproduction. The ideal color copy should be the restoration of the original color. Since the color of the original sometimes deviates, the color copy should meet the copying requirements.

At the same time, in the color reproduction process, it is affected by the conditions of color separation, light source, output material, development, etc. Quantitative evaluation of color reproduction is a very complicated prob wide format inkjet printer lem. Objectively, it’s better if the color of the printed matter and the color of the scene are closer to the physical quantity. However, there is no ideal device to completely replace the eye. And people assess the color often based on the memory or impression of the scene. The memory of the common objects often deviates from the physical color. The color sublimation printing of the people’s favorite color deviates from the actual color. For example, the blue sky is not blue in many cases, and the green trees are not necessarily all green. It makes it difficult for color reproduction of inkjet printers.

In the inkjet printers printing and copying process, people use the neutral gray balance reproduction as the basis for color reproduction. In the range of the tone range, the gray of the different proportions of cyan, magenta and yellow dots of the three primary color inks is printed. It is called neutral gray balance data before and during printing. Therefore, during the entire image reproduction process, neutral gray balance data is used as an important quality standard for monitoring the production process from prepress to printing. In the color copying process: the color should conform to the original, true, natural, and coordinated. The difference between the printed sheets of the same batch of products is less than 5.

The resolution of an inkjet printers is the ability of a printed image to distinguish and reproduce the details of the original image, or the ability of the image to resolve the original scene. The definition refers to the clarity of the image details, mainly the sharpness of the edge of the image and the edge of the line. The resolution of the printed image mainly depends on the influence of the number of screen lines added. But the number of screen lines is restricted by the printing materials and printing methods. The highest resolution can’t always be obtained. And the accuracy of printer printing will affect the resolution of the image. The resolution of the printer will also affect the clarity of the image to a certain extent. Of course, the resolution is also affected by the printing process, materials, technology and so on.

Tips for Quick Drying of Wide Format Printing Machine on Rainy Day

Nanjing is raining now. The rain not only brings inconvenience to people’s lives, but also brings trouble to the advertisement production of the wide format printing machine in the advertising spray painting industry. I believe that many friends have encountered that the picture-taking machine is drying slowly, print media material easily exposed to moisture and other issues under rainy environment. Today, let’s share with you about the maintenance of the wide format printing machine on rainy days.

For a few days of continuous rain, there will be small droplets of water in the air. The user of the large format printing machine should do well to prevent the moisture of the relevant printing materials. Many advertising shops or advertising printing companies store many spare printing materials with different materials. For example, printing cloths, photo papers, and other materials, especially paper materials. It should be stored with care. We can place them on the relevant shelves. They should be set high. Do not hold the walls, floors or windows as far as possible. These are easy to drop from the outside and easy to be dampened. The material that is not used should be packed by packaging box or plastic bag as far as possible. Then store them in a dry and humidity suitable room or warehouse. Besides, we should pay attention to the problem of flooding in low-lying areas.

sublimation printingIn addition to the storage of printing materials, it should also pay attention when printing pictures. In wet weather, the wide format printing machine will have some glitches in the print out of the picture. Ink Affected by the humidity of the weather, the viscosity, consistency and so on are all different. For example, the ink of the wide format printing machine output screen is very slow to dry, especially in the black part. Sometimes the screen is dry very slowly after output, and it takes a long time to dry out. So it affects the time of advertising production.

Our company offers the equipment in sublimation printing process, such as sublimation paper, sublimation ink, wide format printing machine and some other accessories. If you have any demand, please feel free to contact us.

Why Large Format Inkjet Printers Occur Ink Dropping Phenomenon?

The phenomenon of ink drop is that the large format inkjet printer has ink droplets dripping on the output medium during the printing and output process. I believe many users have encountered this kind of problem, I don’t know how you solved it.

The following are the causes and solutions for the ink drop phenomenon in wide format inkjet printers:

1.The viscosity of the ink

Some inks have a low viscosity and are highly fluid. There will also be dripping, but there are fewer problems. If your machine currently has this phenomenon, it is recommended to change the ink with a slightly higher viscosity.

2.Electrostatic factors

After entering the winter, the temperature in each region is generally low, the precipitation is small, and the workshop needs heating. As a result, the indoor air is dry and the humidity is far below the standard required by the equipment (40%-60%), so the static electricity is waiting for the machine. It becomes an important factor in this phenomenon, because the air itself is a natural electrostatic brush. The static electricity generated by the friction of the medium during the painting process needs to be removed from the air. If the humidity in your workshop is low, then it will appear. This phenomenon is not surprising. The solution is actually very simple. If you have the conditions, buy an industrial humidifier or electrostatic brush, or use a small sprayer to sprinkle some water in the workshop from time to time to make the humidity higher.
