Definitions
- the present invention relates to a natural tracing paper for use with ink-jet printers and plotters employing pigment-based inks.
- Natural tracing paper (as opposed to "prepared” tracing paper, also known as “vellum”) is manufactured from wood-based cellulose fibre pulp, which is mechanically treated, for example by crushing and chopping, to remove any air/fibre interfaces. This renders the paper material translucent.
- the finished tracing paper is relatively dense and impervious compared with normal opaque papers.
- EP-A-0631881 describes an opaque printing material comprising a support and an ink receiving layer containing a pigment, a hydrophilic binder and a quaternary ammonium compound.
- Tracing papers have been used for many years for the preparation of engineering master drawings to be reproduced by the diazo process. Although manual drafting has largely been superseded by the use of CAD systems, tracing papers are still used for printing the master drawings.
- Various types of plotter are used for printing the drawings, including pen plotters and electrostatic printers, but one of the most favoured types of plotter at present is the ink jet plotter.
- Some ink jet print heads available at present use dye-based inks. These are satisfactory for most general purpose applications such as printing text and some graphic material, but lack the density and permanence of the pigment-based inks that have traditionally been used in the preparation of engineering master drawings.
- the lower density of the ink means that drawings printed using dye-based inks are not as well suited to the diazo process as those produced using pigment based inks.
- an ink-jet print head that uses pigment-based inks has become available. This print head produces denser images than the previous dye-based ink print heads and the resulting drawings are better adapted to the diazo copying process. The images are also less liable to fading than images produced using dye-based inks.
- a pigment-based ink for use with an ink jet print head typically comprises a dispersion of pigment particles, such as carbon black, suspended within an aqueous vehicle.
- Other ingredients such as surfactants and stabilizers, are usually included to help maintain the dispersion, to prevent blocking of the ink jet nozzles and to promote vaporisation of the ink in the print head.
- a binder such as shellac is not generally included as this can lead to blocking of the ink jet nozzles.
- a natural tracing paper for use with ink-jet printing using pigment-based inks, said natural tracing paper comprising a paper manufactured from a wood-based cellulose fibre pulp that is mechanically treated to render the paper translucent, wherein at least a usable surface of the natural tracing paper includes a combination of a water soluble cationic substance and water soluble binder substance.
- the applicants have further found, however, that if the surface of the tracing paper is also treated with a water soluble or water-swellable binder, the resistance of the ink to abrasion is greatly increased. Therefore, by treating the tracing paper with a binder substance in combination with a cationic substance, migration can be largely prevented and the print quality and permanence of the printed sheet thereby improved.
- the cationic substance may be a soluble polyvalent metal salt.
- Suitable metal salts include the salts of metals from Groups II and III or the Transition Metals of the Periodic Table.
- the metal salt is a salt of a cation selected from the group consisting of Mg 2+ , Ca 2+ , Al 3+ , Zr 4+ and Zn 2+ .
- suitable metal salts include magnesium sulphate, calcium chloride, ammonium sulphate, zinc acetate, ammonium zirconium carbonate and magnesium acetate.
- the cationic substance may be a cationic polymer, and is preferably a low molecular weight, high cationic charge density, water soluble organic polymer.
- the polymer may be a polymeric amine (such as a quaternary amine or easily protonated tertiary amine).
- a suitable cationic substance is a solution in water of a poly-quaternary amine.
- the binder substance may be selected from a group consisting of polyvinylpyrrolidone (PVP), polyvinyl alcohol (PVOH), carboxylated cellulosic polymers, polyacrylic acids, hydroxylated polyacrylates, polyacrylamides, starches (for example oxidised potato starch and potato starch ethers) and gelatine (compounded animal protein in water).
- PVP polyvinylpyrrolidone
- PVOH polyvinyl alcohol
- carboxylated cellulosic polymers polyacrylic acids, hydroxylated polyacrylates, polyacrylamides, starches (for example oxidised potato starch and potato starch ethers) and gelatine (compounded animal protein in water).
- carboxylated cellulosic polymers examples include carboxyalkyl polymers and hydroxyalkyl polymers, and preferably hydroxymethyl cellulose and hydroxypropyl cellulose, and more preferably carboxymethylcellulose (CMC) (especially low molecular weight carboxymethylcellulose).
- CMC carboxymethylcellulose
- Suitable polyacrylic acids include those sold under the Trade Marks POLYMIN SK, PERCOL 1597 and PERCOL 1697.
- polyvinyl alcohol may be used, including those having a low hydrolysis level and a high molecular weight, a low hydrolysis level and a low molecular weight, a high hydrolysis level and a high molecular weight, or a high hydrolysis level and a low molecular weight.
- the binder substance may have a molecular weight in the range 790,000 to 1,350,000 and a viscosity defined by a K-value of at least 30, and preferably at least 60, and advantageously approximately 90.
- the cationic substance is magnesium sulphate and the binder is PVP.
- the amount of magnesium sulphate applied to the surface of the tracing paper is preferably in the range 0.5-3.0gm -2 , and more preferably 1.0-2.0gm -2 , and advantageously approximately 1.25-1.75gm -2 .
- the amount of PVP applied to the surface of the tracing paper is preferably in the range 0.15-0.75gm -2 , and more preferably 0.4-0.7gm -2 , and is advantageously approximately 0.5gm -2 .
- the natural tracing paper is preferably an uncoated cellulose-based paper.
- a natural tracing paper for use with an ink jet plotter or printer using pigment-based ink
- said natural tracing paper comprising a paper manufactured from a wood-based cellulose fibre pulp that is mechanically treated to render the paper translucent, wherein at least a usable surface of the recording sheet is treated with a combination of a water soluble cationic substance and water soluble binder substance.
- the tracing paper is advantageously treated by applying a solution of the combination of substances to the usable surface of the paper.
- the solution is applied by drawing the semi-manufactured paper through a bath of the solution.
- the solution may be applied to the paper by spraying or coating, either during or after completion of the manufacturing process.
- a method of printing in which a pigment-based ink is applied to a natural tracing paper with an ink-jet plotter or printer, said natural tracing paper comprising a paper manufactured from a wood-based cellulose fibre pulp that is mechanically treated to render the paper translucent, wherein at least a usable surface of the natural tracing paper includes a combination of a water soluble cationic substance and water soluble binder substance.
- the effect of applying various substances to natural tracing paper was tested by applying the substances as aqueous solutions to a base paper comprising a 90gm -2 waterleaf natural tracing paper.
- the effectiveness of the substances in reducing migration was assessed visually and the substances were ranked according to the categories excellent, fair, mediocre and poor (in descending order).
- the effectiveness of the substances in binding the printed image to the paper was tested by visually assessing the results of an abrasion test and the substances ranked according to the same categories.
