Abstract
A process for improving the readability of a data-recording line on a chart recording paper whereby the improvement is achieved by moving the recording line across a field largely composed of a matrix of dots. The procedure is particularly advantageous in improving the readability of thin lines achievable with pressure-responsive or thermographic paper, but it is also advantageous when common inking procedures are used. A novel chart paper consisting of a dot matrix format is also disclosed.
