The primary reason for this investigation was to determine if a simple letterpress test could be used to predict the print quality of folding boxboard printed by the offset method.
The experimental plan was to compare the objective ranking of print quality in the laboratory prints with the subjective ranking of print quality in the commercial prints. If the rankings correlated favorably, there would be reason to suspect that this type of test might be applicable in predicting the millroom print quality of folding boxboard.
It was found that the hoped-for correlation did not exist in this particular case primarily because of sampling procedures. However, it appears that an objective range in print quality can be determined using these methods in the laboratory. An idea for further work in this specific area is offered in the conclusion of this paper.
