Vessel cells exist in hardwood pulp. These cells are often relatively intact in the pulp process and can have a negative impact on pulp quality. They can reduce print quality by acting like flakes or not take ink the same way as the surrounding fibres. Dust problems can also occur due to vessel elements coming loose during printing.
“Measuring the quantity and size of vessel elements in pulp is of interest for pulp manufacturers in order to classify pulp,” says Öjvind Sundvall, MD PulpEye. “We have got very positive response from producers of hardwood pulps when discussing this new way of measuring vessel cells in a fibre suspension so the market for our technology is obviously there.”
