Problems solved by technology

However, this solution is not very satisfactory as it leads to an increase in the gloss of the fine paper
Conversely, the use of coarse calcium carbonate (whose particles have a particle size greater than 2 μm) makes fine paper more matte, but increases the drying time of the ink and causes chalking on the felt during offset printing

experiment example 1

[0057] Experimental examples 1 and 2 involve fine paper, Rives Tradition Used in Experiment 1, Conqueror Velin For Experimental Example 2, they were all untreated, ie not covered with a treatment coating.

[0058] The other experimental examples (3 to 12) relate to treated fine papers, ie comprising a pigment and binder based treatment coating on at least one surface of the fine paper.

[0059] In Experimental Example 3, the treatment coating contained 60% of kaolin with a particle size of less than 2 μm as the sole pigment. Therefore, the treatment coating has no silica. The binder in the coating is styrene-acrylic, and the coating also includes a synthetic thickener. 8g / m by air knife technology 2 The rate per side deposits the treatment coat on fine paper.

[0060] The fine papers in Experimental Examples 4 to 12 were all covered with a treatment coating comprising silica under the trademark Syloid ED5 by the supplier Grace. Products on sale. It comprises porous a...

experiment example 5

[0084] The high-grade paper in Experimental Example 5 is a textured paper, so it should be compared with figure 1 and 2 Applies to Rives Tradition in Compare the curves of the paper. The fine paper is covered with a treatment coating such that the amount of deposited silica is 0.47 g / m 2 . like figure 1 As shown, this amount of silicon dioxide helps to make the glossiness of high-grade paper lower than 6% after printing, that is, the glossiness before printing is lower than 3.5%, which is basically the same as the result of Experimental Example 5 (the high-grade paper before printing The gloss is 2.8%, and its gloss after printing is 4.6%) corresponds. Although the amount of silicon dioxide deposited per unit area in Experimental Example 5 (0.47g / m 2 ) is within the range of values ​​suitable for the present invention, but it cannot sufficiently reduce the drying time of the ink, which is 27 minutes.

[0085] figure 2 It clearly shows that, for paper of this quality,...

Abstract

Matt fine paper for writing and / or that can be printed, in particular by offset printing, having, on at least one of its faces, a layer comprising pigments and a binder, the pigments comprising silica, the average particle diameter of which is greater than or equal to 3 [mu]m, and the amount of which deposited per unit of surface area of the layer is greater than 0.4 g / m2 and less than 1.5 g / m2 or the amount of silica of which is alternatively or in combination greater than 6% and less than 15%, in particular less than 10% by dry weight relative to the total dry weight of the layer, the paper having on said face a degree of gloss before printing of less than 3.5%, measured at 75 DEG according to the Tappi TM T480 standard.

Description

technical field [0001] The present invention relates to a high-grade matte writing and / or printing paper (also known as graphic paper), especially for offset printing, which printing paper has a short drying time for ink and / or ink, And the invention also relates to a method of making the paper. This high-grade paper can be used in many fields, such as art publishing, writing, packaging and so on. Background technique [0002] In the printing paper industry, various papers can be distinguished according to different purposes, each corresponding to a user with a particular type of printing press and to a particular market. Accordingly, customers in the paper industry select from various papers on sale the paper that is suitable for printing on the printing machine to be used and that can best meet the customer's needs in terms of quality and cost. [0003] There are many types of printing presses or printing, including desktop inkjet printing presses, continuous inkjet prin...
