摘要
用７种纸张与８种油和油墨结合进行拉毛的研究发现，对于一定纸张，在印刷中发生拉毛时，与其临界拉毛速度相对应的油或油墨的临界Ｔａｃｋ值为一常数，而临界拉毛速度与油墨粘度的乘积（ＶＶＰ值）并非一个常数。油或油墨的Ｔａｃｋ值随印刷速度的增加而增加。临界Ｔａｃｋ值度量了纸张拉毛阻力的大小，Ｔａｃｋ值与速度的关系度量了油墨拉毛强度的大小。
Pick tests were carried out using eight kinds of liquids (pick oil and ink) and seven grades of paper to study the relationship between tack and viscosity,tack and picking resistance of paper. It has been found that irrespective of the type of liquid the critical tack, i. e. the tack of the liquid at the picking velocity, is constant for a given paper. The product of the viscosity of the liquid and the picking velocity of paper (VVP) is not constant for a given paper. Whereas the critical tack measures the picking resistance of paper, the tack-speed relationship is the characteristic of the picking strength of ink.
