LintView tester

Linting of uncoated paper types can lead to problems during printing or processing. For the paper industry, it is important to be able to test the paper for any tendency to loose fibers during the production process. With the LintView Tester, IGT Testing Systems offers a fast, simple and accurate system to detect lint.

The linting of uncoated paper types is caused by the release of fibers or fiber bundles from the surface of the paper. This form of linting must not be confused with problems involving paper dust or with the picking of the coating from coated paper types. Dust is not part of the paper and is released easily. While the shedding of these dust particles during printing does not damage the paper, it can cause printing problems. Pick of the coating on coated paper types also causes issues, but considerably more force is needed for pick to occur than for linting, as can happen with high tack inks.

Various test methods exist for determining and measuring linting. However, these tests are often time-consuming or do not always provide the necessary information. Moreover, they usually occur at a late stage in the process, often months after the paper is manufactured, namely when the paper is already on the printing press.

It is crucial for paper manufacturers to test the paper quickly, easily, and accurately during production, across the width of the paper machine and on both sides. Additionally, analyzing the measured data swiftly is essential to identify and suppress the tendency to linting. The IGT LintView Tester enables this capability.
