X-Rite Inline Color Measurement Solutions For Paper Mills

Quality Color with Less Waste for Better Market Acceptance Papermaking has always been a complex process. The pulp is produced from wood or recycled paper as well as a variety of chemicals, dyes, and papermaking agents to achieve stability and remove impurities. Each of these raw and recycled materials impacts the color of the pulp and final paper, which must fall within tight color tolerance or the customer will not claim the shipment. On a fast-moving paper line, even a slight color shift can ruin an entire run in no time. In addition, today’s consumers are also looking for a paper company...

Make Decisions Based on Fact, Not Guesswork • See real-time color data of the running production line Get early notification of color shifts Automatically adjust dye pumps to bring color back into tolerance Take corrective action before a run is wasted Automatic start-up and shade changes for up to 50% quicker...

Total Color Control on the Paper Production Line An inline color measurement and control system includes a non-contact spectrophotometer mounted on a custom frame over the production machine and closed loop color control software to monitor color throughout the run. The inline spectrophotometer can be mounted in three locations. 1 2 2 2. After the Press Section Measuring the pulp acts like a pre-warning system to notify operators what will be on the machine soon. Measuring the wet paper before drying offers a good correlation to the finished product. The most common place for color measurement...

The Ultimate Solution for Accurate Paper Color Color and brightness are typically the last parameters to be brought into specification at machine startup. An inline color measurement and control system uses a mathematical model to calculate the color changes for up to 3 dyes and optical brightening agents (OBAs) if required as the operators set up the machine. This saves a lot of time during start up and shade/grade change. If color deviates during production, operators can quickly re-adjust dyes and OBAs to get back on target, reducing colorant and paper waste for a more sustainable process....
