Practical examples of ColorTALLY show what is possible. In order to interpret the graphs, first a couple of pointers:
- The graphs are based on real-life data.
- For each example, the top graph shows trend of a production process which is not optimized. The bottom graph shows the trends after process optimisation.
- Each dot on the graph is color measurement data for a specific print job.
- The black horizontal line is the target reference.
- The orange/red horizontal line shows the agreed tolerances.
- The X-as shows the number of print jobs for a specific period.
35% less make-ready time because you monitor your real average density.
ColorTALLY shows average density of several print jobs. Every color (CMYK) deviates from the reference density. As a corrective measure, the printing house agreed on a common start-density. In addition training and coaching during production was implemented.
Make-ready times not only decreased with 35%, also color consistency between print runs improved.
No expensive ‘fingerprints’ or test runs. Correct dotgain based on reliable statistical data.
ColorTALLY shows average dotgain variation over a certain period to time. Usually you would perform expensive printing test when correcting for inaccurate dotgain curves. These test are always performed on a specific moment and they do not take into account overall production fluctuations over a longer period of time. When using statistical data from ColorTALLY, dotgain curves are corrected taking into account typical characteristics/fluctuations of your process.
This gives a much more accurate and realistic dotgain correction and ... you do not lose any valuable press time.
ColorTALLY gives insight in your real make-ready waste and make-ready time.
Are you absolutely certain about your actual make-ready? Big fluctuations in make-ready is for all printing companies very costly and it brings your productivity down. The graph above shows some occasions where the jobs has make-ready well within tolerance (below the orange reference line). ColorTALLY helps you to understand your real make-ready. Based on this you can improve procedures on start density and improve dotgain.
Reducing make-ready time and waste improves productivity and reduces cost.
Identify left-right deviations and adjust ink rollers based on statistical data from ColorTALLY.
When you see left-to-right color deviations it makes more sense to base corrective actions on statistical data over a longer period of time. The choice of ink unit and how much change must be implemented takes into account statistical averages of your specific process.
Your maintenance time will decrease and productivity increases due to more press up-time.
