Printing paper and method for producing printed material
Printing paper is provided that is able to inhibit the occurrence of cockling and wrinkling during printing and inhibit the occurrence of curling after printing when cut into sheets in the case where inkjet printing is carried out in a rotary inkjet printing press while tension is applied from the time the printing paper is rolled out until it is taken up. The printing paper comprises a base paper and a coating layer containing a pigment and a binder on at least one side of the base paper, wherein an ash content of the base paper is 20% by weight to 30% by weight, and specific tensile strength of the printing paper in the CD direction is 9.0 N.Math.m/g or less, and the ratio of (specific tensile strength in the MD direction)/(specific tensile strength in the CD direction) is 1.9 to 2.3, wherein the specific tensile strength is as determined basically in compliance with JIS P 8113:2006.
METHOD FOR MANUFACTURING PANELS HAVING A DECORATIVE SURFACE
Panels having a decorative surface may include a plate shaped substrate and a top layer, and the top layer may include a paper layer having a printed pattern. A method for manufacturing such panels may involve providing the paper layer with a treatment, including providing the paper layer with an ink receiving substance. The treated paper layer may be provided with at least a portion of the printed pattern by depositing pigment containing inks using a digital inkjet printer. The pigment containing inks may be water-based. The digital inkjet printer may include print heads with nozzles for firing droplets of pigment containing inks onto the treated paper layer. The paper layer may be fed from a roll, printed upon, and rolled back up again. The paper layer, while printing, may be flexible and may be attached to the plate shaped substrate after printing. A layer of thermosetting resin may be applied above the paper layer and the printed pattern. Providing the layer of thermosetting resin may involve a press treatment. The paper layer may be a colored base paper, a pigmented base paper, and/or a dyed base paper.
Manufacturing of decorative surfaces by inkjet
A method for manufacturing decorative surfaces includes the steps of a) inkjet printing a color pattern on a paper substrate with one or more aqueous inkjet inks of an aqueous inkjet ink set; and thereafter b) impregnating the paper substrate with a thermosetting resin, wherein the aqueous inkjet ink set includes a cyan aqueous inkjet ink containing a copper phthalocyanine pigment; a red aqueous inkjet ink containing a pigment C.I Pigment Red 254 or a mixed crystal thereof; a yellow aqueous inkjet ink containing a pigment C.I Pigment Yellow 151 or a mixed crystal thereof; and a black aqueous inkjet ink containing a carbon black pigment; with the proviso that the aqueous inkjet inks do not include a polymer latex binder; and that the paper substrate includes one or more ink receiving layers for improving the image quality of the aqueous inkjet inks jetted thereon.
Printing paper for industrial rotary inkjet printing press and method for producing printed material
Printing paper for an industrial rotary inkjet printing press is provided that has superior printability with respect to an offset printing press, and has superior color density uniformity, inhibition of ink strike-through and dot reproducibility with respect to an industrial rotary inkjet printing press using water-based pigment ink. The printing paper for an industrial rotary inkjet printing press comprises a base paper and at least one coating layer containing pigment, binder and water-soluble polyvalent cation salt on at least one side of the base paper, wherein at least one of the pigment is kaolin having an average particle diameter of 0.20 μm to 1.50 μm, and the content of the kaolin in the coating layer is 50 parts by weight or more based on 100 parts by weight of the pigment in the coating layer, the content of the water-soluble polyvalent cation salt in the coating layer is 1.0 parts by weight to 6.0 parts by weight based on 100 parts by weight of the pigment in the coating layer, and the surface resistivity on the coating layer side of the printing paper in an environment at 23° C. and 50% RH as determined basically in compliance with JIS K 6911:2006 is 2.0×10.sup.10 Ω to 5.0×10.sup.12 Ω.
PRINTING SHEET AND METHOD FOR PRODUCING PRINTING SHEET
Provided are a printing sheet that has excellent printability, excellent adhesiveness between a substrate and a coating layer, and excellent antistatic performance and thus is less likely to cause troubles such as paper jams during printing, and further has excellent properties such as water resistance and weather resistance in the printing sheet having the coating layer for receiving an ink on at least one surface of the substrate and a method for producing the same. The printing sheet includes the coating layer by blending clay in a proportion of 35% by mass or more and 65% by mass or less and light calcium carbonate in a proportion of 5% by mass or more and 30% by mass or less in a continuous phase made of an acrylic polymer.
Image transfer material and polymer composition
Provided is an image transfer material, comprising a support, optionally at least one barrier layer, a melt transfer layer, and an image receiving layer. Also provided is a process for preparing the image transfer material. Further provided is a heat transfer process using the disclosed material. In the heat transfer process, after imaging, the image receiving layer and melt transfer layer are peeled away from the optionally barrier-coated support material and placed, preferably image side up, on top of a receptor element. A non-stick sheet is then optionally placed over the imaged peeled material and heat is applied to the top of the optional non stick sheet.
