Digital Color Management
A practical use case
A printing company used to print for more than 10 years on a digital printing system that didn’t print colors neutrally. The company was at the time of the installation of the printing device badly advice regarding the color management methodology. In order to correct for the constant color shift the printing system produced, the prepress department applied a color correction rule within photoshop to all images to be printed on the digital system. These images were stored with the correction applied in the image library.
The company recently installed a new digital printer in order to replace the old one. It turned out, the new printer prints the images in sRGB colorspace correctly. The company faced the problem to print existing image data from the color-adjusted library on the new system as all existing image. The customer consulted several color-management service providers without getting an acceptable solution.
The company eventually contacted DAPF TECH. We were able with our advanced color management techniques remotely.
How did we do it?
First, we sent an RGB-Testchart to the customer which they adjusted the same way they adjusted the image data for the old printing device. Next, we created a synthetic ICC-profile based on the altered RGB-chart. Then we assigned the synthetic ICC-Profile using a Linux-script to the whole of the image library and converted the images automatically back to sRGB colorspace.
Using this method, we were able to correct the complete image-database of about 40 GB data in less than 2 hours to its intended colors. Now the company is able to reprint former jobs and reuse the same images without any further adjustments in the workflow.
Total time needed: 2,5 hrs
Total costs: EUR 200
