Common Problems and Solutions for Industrial Inkjet Printing

Industrial inkjet printing has revolutionized the way businesses print, enabling them to produce high-quality, complex images at an unprecedented speed. However, like any technology, inkjet printers can experience various issues that hamper their productivity, resulting in loss of time and money. In this article, we will discuss some of the most common problems with industrial inkjet printing and their solutions.

Clogging Nozzles

One common problem with industrial inkjet printers is clogging nozzles. When the ink dries up inside an uncapped nozzle, it blocks the flow of ink, reducing its output quality or entirely preventing printing from the nozzle. Clogging could result from factors such as changes in temperature or humidity, regular ink formulation, dry ambient conditions, or unclean or improper maintenance of the printers.

Solution: To fix clogged nozzles, conduct a head cleaning process to unclog the affected nozzle. Most printers have a built-in cleaning program; consult the printer manual for the specific steps for your model. Minimizing the time the nozzle is uncapped can help reduce or eliminate clogging. If the issue persists, consult a professional to clean the printer or replace damaged nozzles.

Poor Print Quality

Inkjet printers are primarily known for their superior image quality, so when that quality is reduced, problems develop. Poor print quality can result from various factors, including poor ink delivery, defective nozzles, or incorrect printer settings.

Solution: Ensure that the ink formulation and type are suitable for the printer and application. Correct the printer settings, such as print speeds, resolutions, and color profiles, to improve quality. Conduct regular maintenance, such as cleaning, to keep the printer operating at its optimal level. If there are defective nozzles, then replace or repair them to avoid degrading the quality of the printed images.

Bandings

Bandings are stripes or lines that appear horizontally or vertically on the printed images. They are unwelcome and easy to recognize.

Solution: Improper ink formulation could cause bandings, so use the right ink formulation and type for the application. Conduct regular maintenance to keep the printer in optimal condition and prevent bandings. Adjust the print resolution or check that the ink settings are correct if the problem persists.

Color issues

Inkjet printers often undergo color issues, from mismatched colors, printer color management settings, or aging ink.

Solution: Check that the ink formulation and type are compatible with the printer and application. If the printer features color management settings, then ensure that they are correctly adjusted for the desired output. Ensure that ink cartridges or tanks are not old or expired. Lastly, confirm that the color calibration settings are correct.

Paper issues

The wrong type of paper can cause inkjet printers to experience printing issues. From poor ink absorption to milky ink effects, wrong paper choices could hamper printing quality.

Solution: When selecting paper, consider the printer model, ink type and formulation, image quality, paper quality, substrate type and size, and intended use. Ensure the paper is within the recommended specs of the printer to avoid image distortion, smudging, and other paper-related issues.

Conclusion

Industrial inkjet printers have brought about significant gains in productivity in various industries, including textiles, graphics, packaging, and labeling. However, they are not exempt from errors and common problems that could cause downtime and loss of business. Regular printer maintenance, correct diagnosis of problems, and possible solutions can go a long way in maintaining high-quality, efficient printers. Keep up-to-date with best practices and appropriate use for your industrial inkjet printer, and you can avoid many of the common issues that arise.
