Summary of faults related to poor printing quality of inkjet printers

Summary of faults related to poor  #printing quality of  #inkjet printers

The possible reasons for the point loss near the recovery port side are ink accumulation at the recovery port, incorrect  #ink line position, too low character height setting, and excessively high ink path pressure. It is necessary to clean the recovery port, adjust the position of the ink line, adjust the character height to an appropriate value, and adjust the ink path pressure to an appropriate value. 2. The possible reasons for the loss of dots on the side far from the recovery port are that the ink path pressure is too low, the ink line position is incorrect, and there is ink on the deflection plate. It is necessary to adjust the ink path pressure to an appropriate value, adjust the ink line position, and clean the deflection plate. 3. The possible reasons for the deformation of printed characters may be that the ink path pressure is too low (the character shape is loose), the printing distance (the distance between the nozzle and the product surface) is too far, the split point difference, and the concentration exceeds the range. It is necessary to adjust the pressure, the printing distance and the splitting point. Check whether the  #nozzle bracket is stable. 4. If the printing position is incorrect, check whether the product delay value set in the information parameter menu is correct, verify if the information editing is correct, and check if the position and fixation of the photoelectric eye installation are correct. 5. Incorrect print size: Check whether the  #character shape,  #font height and font width of the print information parameters are set correctly, check the distance between the print head and the object to be printed, and check whether the print head support is stable. 6. Incomplete printing information: Check whether the number of character dots in the printing information parameter Settings is the maximum dot matrix required, and inspect if there are ink deposits at the  #nozzle outlet, which may clog the nozzle. 7. If the adhesion of the printed material is poor, check whether the viscosity of the ink is within the normal range and whether the surface of the printed object is clean. Check whether the ink and additives have exceeded their expiration dates. 8. In case of missed spraying, clean the photoelectric sight glass, adjust the sensitivity of the photoelectric eye and its installation position to ensure that the photoelectric eye can sense every continuously moving object being sprayed, and eliminate the influence of the object's surface color on the photoelectric eye's sensing. Adjust the production line to ensure that the products do not have excessive vibration when passing through the position sensed by the electric eyes.

Printing knowledge - screen printing ink preparation and recycling method

  Printing knowledge - screen printing ink preparation and recycling method In the process of screen printing, the first problem encountered before printing is the deployment of ink color, whether color real reproduction directly affects the product quality and market space share. To make customers satisfied, you first need to know how to improve the quality of ink by using ink color blending techniques. 1 screen printing ink to find a container to put ink to avoid waste (it is recommended to use a transparent disposable cup, easy to be easily poured into the right amount of ink (how much to pour) The ink preparation method is clear basic requirements: first determine the printing material (paper, plastic, metal, etc.), select the corresponding system of ink (such as screen printing plastic ink for plastic, high temperature curing ink for metal). With the basic color as the main body, a small amount of auxiliary color is added, and the amount of each amount is not more than 5% of t...

Printing knowledge - field printing shows maximum saturation

  Printing knowledge - field printing shows maximum saturation   Four-color printing is printed with CMYK(cyan, magenta, yellow, black) four-color overprint that you need. In the popular point, that is, you can use these four different colors to add up to get the color you need. Field printing refers to 100% color, such as 100% black is field black, and printing a large area of color block on printed matter. 1 There are a lot of people in the field saturation in the printing product color saturation do not know how to deal with, it is easy to cause unnecessary loss, theoretically, is to give full play to the maximum field density of #offset #printing #ink to achieve the maximum saturation. Although 95% of the dot will increase to 100% after printing, this is different from the effect generated by 100% field printing. 95% of the dot only reaches the field in 95% dot area, while 5% of the dot area has ink, but the ink #density is thinner. 95% of the dot increases to 100% in...

Analysis of the Causes of Pressure Faults in Inkjet Printers

Image
  Analysis of the Causes of Pressure Faults in# Inkjet Printers 1 The ink line speed is normal, but there is pressure loss or it is too high (1) Check if there are any additives in the additive bucket and replenish them. Check the viscosity of the #ink to determine if it has become thinner (check if the printed characters are too light). Otherwise, the entire machine should be cleaned. For machines that have not undergone regular maintenance, the #filter elements and filter screens must be replaced. (2) Check if the shape of the breakpoint is correct and adjust the breakpoint. (3) Check whether the electrode of the nozzle is clean and clean the #nozzle. 2 Pressure loss fault caused by #pump motor failure (1) Pump motor failure leads to power loss, resulting in total pressure loss and pressure fault display. (2) The motor is disconnected from the pump. At this time, although the motor is rotating, the gear at the front end of the pump does not rotate, resulting in total pressure los...
