Definitions

  • the invention relates to a printing paper according to the preamble of claim 1, which is to be used in particular for offset or gravure printing. Furthermore, the invention relates to a method for producing the printing paper and its use.
  • DE-B-12 21 893 describes the production of coated printing papers, starch being made cold-soluble in some cases by mechanical treatment in a pan mill so that it is still dissolved by the evaporating water of the coating slip during drying following the coating process and in dissolved or gelatinized form in a manner known per se as a binder for fixing the pigments such as chalk.
  • the papers produced are certified to have a high gloss. The problem of the rub resistance of the printing inks is not addressed.
  • banknote paper is known in which to avoid fiber detachment and to increase the resistance to soiling, the surface is provided with a coating which, from a special plastic binder, contains 0.5 to 10 parts by weight of very fine rice starch and, if appropriate, further inorganic pigments. The problem of abrasion resistance does not arise with such papers.
  • Matte printing papers have the great advantage that, on the one hand, the printed products produced with them do not produce any annoying light reflections and, on the other hand, in conjunction with suitable printing inks, the actual printing, in particular the multicolor printing, has a very excellent printing gloss, which increases the quality of the printed product.
  • Calcium carbonate has been widely used in the past few years to produce such matt-coated printing papers.
  • Scrub resistance is understood to mean the resistance of a layer of printing ink to mechanical stress due to pressure loading and friction during the further processing of the printed sheets and when using the finished printed products.
  • the object of the present invention is therefore to provide a matt-coated printing paper which has improved rub resistance and reduced susceptibility to glossy strips.
  • the invention provides the characterizing features of a printing paper according to the preamble of claim 1.
  • Claims 2 to 9 characterize preferred design options for the printing paper.
  • a method for producing the matt coated printing paper is specified in claims 1O and 11 and the use of the printing paper in claim 12.
  • non-gelatinized starch granules which are practically present as a coating pigment in the coating in an amount of 10 to 65% by weight, based on the dry content of the coating for taking up the printing ink, the coating being a further pigment Contains calcium carbonate, a paper suitable for the production of high-quality printing work, the rub resistance and susceptibility to gloss streak development is significantly improved.
  • coated paper according to the invention can now also be used to provide smooth but non-glossy papers for the gravure printing process, as are required in particular for printed products with long runs.
  • the printing paper according to the invention preferably contains starch granules whose gelatinization temperature is increased by chemical modification known per se. Such a modification is very preferably achieved by the starch granules designated in the characterizing part of claims 3 and 4, the gelatinization temperature being able to be influenced by the choice of the degree of etherification or esterification.
  • the size of the starch granules is expediently chosen depending on the average size of the calcium carbonate pigment. Starch granules with an average grain diameter of 7 ⁇ m to 50 ⁇ m are preferred, but starch granules with an average grain diameter of 15 to 25 ⁇ m are particularly preferred.
  • the selection can be made using the known separation techniques, such as hydrocyclone separation according to DE-OS 234157O.
  • non-gelatinized starch granules are: corn, potato, wheat, rye or tapioca starch.
  • corn or potato starch is particularly preferred because it is sufficiently available and inexpensive.
  • the line for taking up the printing ink can also contain other white pigments known and customary in paper coating technology.
  • the proportion of these pigments should expediently not exceed 15% by weight, based on the solids content of the coating, with all proportions, including binders and auxiliaries, adding up to 100% by weight.
  • the coating slip contains 5 to 14% by weight, preferably less than 10% by weight, of conventional binders such as plastic latices, gelatinized, degraded starch or other known binders from paper coating technology, dispersants, optionally further white pigments and viscosity regulators.
  • the solids content of this coating slip is adjusted to 40 to 72% by weight, preferably 55 to 63% by weight.
  • the viscosity of this coating slip is adjusted to 5OO to 4OOO m Pas, measured with the Brookfield viscometer, spindle no. 4 at 50 rpm.
  • a higher viscosity for roller application and a lower viscosity for doctor blade, air brush or blade application are preferred, the viscosity being adjusted by adding conventional, known water-soluble polymers, such as polyvinyl alcohol, carboxymethyl cellulose or polyacrylic acid derivatives.
  • the pH of the coating slip to be applied is 8 to 10, preferably 8.8 to 9.2 and is adjusted during the preparation of the coating slip, if necessary by adding alkali.
  • the paper coated with it is dried to a final moisture content of 92 to 96% dry using known drying processes such as IR emitters, hot air floating dryers or cylinder dryers and then trimmed to the desired roll or format width.
  • the coated paper produced in this way is to be used for gravure printing, it is subjected to a known calendering treatment, with 2 to 8 roller nip passes producing the necessary smoothness on the paper at a line pressure of 50 to 4OO da N / cm, without a noticeable increase in gloss to cause.
  • a common primer formulation contains, for example, 100 parts by weight of ground chalk with a grain size of 70% ⁇ 2 ⁇ m, 10 parts by weight of oxidized, gelatinized starch and 9 parts by weight of a styrene-butadiene plastic binder as a binder, as well as other aids for pH and viscosity control as calcium carbonate pigment .
  • the solids content of such a primer is depending on the application of the primer from 55 to 72 % By weight atro adjusted, the stroke application per side being chosen between 6 to 15 g / m 2 atro.
  • the method according to the invention can be used to produce matt papers coated on one or both sides.
  • the coated papers each have a basis weight of 115 g / m 2 , measured in accordance with DIN 531O2 and ISO 536.
  • the specific volume was measured according to DIN 531O5, the smoothness according to DIN 531O7 and the gloss with the Lehmann gloss meter at a reflection angle of 75 degrees.
  • the pick test was determined in accordance with. Information sheet for the IGT device carried out, the evaluation was carried out on an assessment scale from 1 to 6.
  • the unsaturated patterns of Examples 1 to 3 and the comparative example were used to produce proofs with a defined amount of ink, so-called weighed proofs, with the test printing device from fürbau. After the ink had dried for at least 24 hours, the abrasion resistance test was carried out using the Oser abrasion resistance tester under defined conditions. The printed surface is rubbed against the same side or the back of the Paper, each unprinted, for a period of 3 minutes with a load of 625 g. The assessment can be made visually or by contrast measurement with the Elrepho device at the unprinted point. The visual assessment with a grade of 1 to 6 resulted in the following classification of the examples:
  • the examples according to the invention have a much lower gloss than the comparative example, both in the unsatinated and in the satin state, and that the so-called matt effect increases with increasing proportion of native non-gelatinized starch in the coating slip, without the susceptibility of the unsatinated dried line increases to form gloss streaks.
  • the coated paper is satinized, on the one hand the gloss does not increase significantly above the value of the unsatinated comparative example, on the other hand a sufficient smoothness increase can be achieved which makes the printing paper according to the invention suitable for the gravure printing process.
