Embodiment Construction

[0028] Attached below figure 1 and figure 2 Further explain how the present invention is realized:

[0029] Use IGT printing suitability tester AIC2 type, the experimental conditions are: printing pressure: 450N, printing speed 0-3m / s (uniform acceleration), room temperature 23±1℃, relative humidity 50±2%; in a 10μL ink distributor Make the rubber plate 1 evenly inked, and the ink volume is 0.6mL to form a uniform ink layer 5 of offset printing ink; then install the inked rubber plate 1 on the tester, and at the same time install the tested paper 4 on the fan of the tester On the cone surface of the cone 2, close the pressure, so that the rubber plate 1 and the paper 4 to be tested are in the activated state, and the direction of the paper is vertical. Then 5 μ fountain solution (50% isopropanol and 50% pure water (volume ratio)) was dropped in the middle of the top of the rubber disk 1 with a 3.2 cm micro-syringe 3 . Pull the start switch, so that the ink and dampening so...

Abstract

This invention discloses a measurement method for paper inking, which directly adopts the brushing printing principle. The method is the following: to make fountain solution on the rubber disc evenly inked in the IGT AIC2 printing compatibility detector and the ink simultaneously distribute on the paper under pressure to form a ellipse; to measure the long radium of the ellipse to give the qualitative value on the paper inking and to give the quantitative value on the paper inking through the measurement and simple formula calculation. This invention can be used in the quantitative and qualitative value on the paper inking property.

Description

technical field [0001] The invention relates to a method for detecting the inking property of printing paper, so as to grasp the printing performance of the paper and effectively prevent printing waste products caused by the paper. Background technique [0002] As we all know, the chemical materials, sizing materials and papermaking processes used in papermaking are different, and the surface conditions (including physical and chemical aspects) of the formed paper are also different. Even if the same ink and printing conditions are used, the printing effect on different papers will be different. However, if the paper with different surface conditions will get the same printing effect under different inks and different printing conditions, it is difficult to distinguish with the naked eye. This is because the different inks and printing conditions used can offset the differences in the paper surface. The difference in printing effect. [0003] General printing plants can on...
