2,3M Creative Company discloses application number and has been " US20030232210 " denomination of invention United States Patent (USP) for " inking foam object ", this patent is addressed the method that detects printing and ink adhesion: the model film is placed on the heating plate, with the spraying of standard black ink in its surface, coating film wore out 3 hours under 75 degree, after the drying, roll downwards with a masking tape, this calibration tape is peeled off from the surface immediately with 90 ° of angles then.The quantity of ink quantitative test grade that this film is removed with calibration tape.
3, the printing ink of having narrated the offset printing newsprint is accepted the performance assay method nineteen ninety-five " Chinese papermaking ".This method be adopt on IGT AIC2-5 printability instrument that the mode of simulation newsprint offset printing carries out (comprise paper not by fountain solution the inking effect when wetting and by fountain solution wetting inking effect after once).Pattern printed back 24 hours, utilized TB-K type multifunctional optical fabricmeter to measure printing and reached the reflectivity that does not print pattern, calculated the reflection density of printing.Accept performance by analyzing different patterns at the printing ink of first look and the second look printing, integrated printing density is estimated this pattern and whether is suitable for news printing.
4, U.S. TAPPI has organized to set up and has tiltedly dripped the association criterion TAPPIUM 536 that the seepage method of testing is measured inking.
Although above several method can detect the inking of paper, its limitation is arranged, complicated operation is not suitable for the detection of common paper inking.How the black situation that is subjected to of paper surface (comprising coated paper and uncoated paper) truly and effectively being reflected by simple method, is a problem demanding prompt solution.
Summary of the invention
The object of the present invention is to provide a kind of simple to operate, assay method of being applicable to plain paper inking mensuration.
Realize that technical scheme of the present invention is as follows: the present invention directly adopts the principle of offset printing to utilize IGT AIC2 printability experiment instrument to study paper surface inking degree, promptly uses the method for offset printing ink under neat, and concrete grammar is as follows:
A, at the even fountain solution of (ink film thickness is fixed) titer on the rubber dish of inking of IGT AIC2 printability experiment instrument, make the pressurized distribution expansion on paper simultaneously of printing ink and fountain solution, to form two zones on tested paper: a zone is by formed elliptical region not of uniform size (because the hydrophilic ink-receptive degree varies sample of paper surface of quantitative fountain solution, therefore the depth of formed oval-shaped size and ellipse self mass colour is also different), another zone is the ink lay zone; Wherein, squeegee pressure is 450N, and print speed printing speed is the even acceleration of 0-3m/s, and described inking amount is 0.6mL; Described fountain solution is the 5 μ L mixed liquors of 50% isopropyl alcohol and 50% pure water by volume.
The qualitative evaluation of B, paper inking: after treating the pattern drying, measure oval-shaped major diameter Φ, major diameter Φ represents the resin added of paper, and greatly then inking amount of major diameter Φ is little, and the little then inking amount of major diameter Φ is big;
C, to the quantitative evaluation of paper inking: after treating the pattern drying, detect oval-shaped staining value with colour photometer; The inking expression formula of paper is as follows:
IA＝6-GS，
Wherein: IA represents the inking value (ink Acceptability) of paper, is called for short IA value (paper inking represents that paper accepts the characteristic of printing ink, is infiltration, the absorption of paper self, the concentrated expression of ink affinity).
GS is a printing ink staining value.
Printing ink staining value " color shade " (ISO Grayscale for staining) standard method of test of adopting international standards detects in the described C step, and this method detects easy, and grade classification is also clearer and more definite.
Described fountain solution can be the mixed liquor of 50% isopropyl alcohol and 50% pure water (volume ratio).
Described test paper is coated paper or uncoated paper.
The present invention directly adopts the principle of offset printing, at the even fountain solution of (ink film thickness is fixed) titer on the rubber dish of inking of IGT AIC2 printability experiment instrument, make the pressurized distribution expansion on paper simultaneously of printing ink and fountain solution, form two zones on tested paper: a zone is by the formed elliptical region of quantitative fountain solution; Another zone is the ink lay zone.By measurement to the oval major diameter of specimen page, can provide the evaluation qualitatively of paper inking, calculate by measurement and simple formula specimen page printing ink staining value, can provide the quantitative evaluation of paper inking, method of testing of the present invention is simple to operate, cost is low, be applicable to the evaluation of the qualitative and quantitative property of plain paper inking.
