Analysis on Elimination of Chromatic Aberration in Printing Process

Using a spectrophotometer on the press, once the color of the ink has matched the look of the user, you can turn your attention to ensuring that the color falls on the substrate to the desired level. Even other costs can be saved by using a spectrophotometer. For example, after reading a few readings on the press, you can confirm that if you use a higher mesh number of screens to reduce the amount of ink you can still meet the user's requirements.

The ICC color rendering file helps eliminate chromatic aberrations caused by variables at each stage of the production workflow, from prepress computer displays, scanners and images to the nature of screens and stencils in screen-making workshops, and production Prepress settings in the workshop. The ICC workflow is valuable to screen printers because digital prepress and full color digital output systems have begun to be included in the workflow.

As digital printers play an increasing role in producing wide-format color images, it is critical to ensure color accuracy between the screen and digital images. Fortunately, the spectrophotometer does not cause problems due to pigment color cast. It measures any form of printed image to balance the production system for printing these images, so that the final result provided by each technology is consistent.

The spectrophotometer measures the color quickly. Many front-end RIPs have a checksum function that usually works with a spectrophotometer to make the daily output values ​​the same.

If you plan to use ICC color correction files for your daily work, it is best to purchase a benchtop spectrophotometer. When considering creating an ICC profile for an inkjet printer or screen printer, it means reading thousands of readings, which is reasonable if you have a desktop device, especially one that automatically scans the color samples. . It is even possible to consider the purchase of models specifically developed for ICC profiles to further streamline the process.
