84.42 Machinery, apparatus and equipment (other than the machine-tools of headings 84.56 to 84.65) for preparing or making plates, cylinders or other printin components; plates, cylinders and other printing components; plates, cylinders an litho a Bic stones, prepared for printing purposes (for example, planed, grained or polisEd. f - Machinery, apparatus and equipment 8442.40 - Parts of the foregoing machinery, apparatus or equipment 8442.50 - Plates, c linders and other printing components; lates, cylinders and 8442.30 lithograp&c stones, prepared for punting purposes ffor example, planed, grained or polished) Apart from certain exclusions referred to later, this heading includes : ' (1) The printing parts of printing machinery, for example, plates and cylinders, engraved or otherwise prepared for printing, used to rint texts or illustrations (by hand or by the machines of heading 84.43); and re are lithogaphic stones, cylinders and plates (i.e., those prepared so as to be suitab e or engraving or otherwise receiving an image for subsequent use in printing). PF (2) The machines, aratus and accessories used to make the printing arts referred to above, (compose) it for use in printing, whether by han? orImechanically. This heading covers equipment used in the printing of texts, illustrations or repetitive designs, etc., whether on paper, textiles, linoleum, leather or on other materials, by printing processes, viz. : (I) Relief printing : by using relief photo-engraved plates. In this process, the relief parts of the character or image are inked. (II) Planographic printing : by lithography, photo-lithography or b offset printing. The printing ink is applied only to certain specially pre ared parts of t ie plane surface of the printing plate, etc. This category of printing also inc udes stencilling. f ' (111) Intaglio printing : by rotogravure, or by means of etched or engraved metal plates. The printing ink is accumulated ~nthe engraved or etched parts. (A) MACHINERY, APPARATUS AM) EQUIPMENT (OTHER THAN THE MACHINE-TOOLS OF HEADINGS 84.56 TO 84.65) FOR PREPARING OR MAKING PLATES, CYLINDERS OR OTHER PRINTING COMPONENTS This heading includes : (I) Machines for making printing plates by direct reproduction from a document. In these machines, a photocell scans the document, and the im ulses transmitted by an electronic device from that cell activate a tool which engraves a p ate of plastics. ! (2) Machines for acid etching plates or cylinders. These consist of special vats fitted with stirrers. (3) Machines for sensitising offset zinc plates (horizontal whirlers), generally fitted with an electric heating device. The heading covers only phototype-setting or composing machines which actually set , even if the type is photographed after it has been set. However, the heading exclu es photographic cameras, photographic enlargers or reducers, photographic contact printers and similar photographic apparatus for prepanng printing plates or cylinders (Chapter go), for example : T (a) vertical or horizontal process cameras mounted on a hanging frame (bed) or a sliding bed, cameras for three colour pmting; (b) photographic enlargers and reducers, reproduction apparatusand printing fiames; (c) light tables used for planning layouts or for contact printing. Some of these ap aratus use half-tone or similar finely cross-lined glass or plastics screens, glass or plastics co our filters for colour printing or screen or filter holders. f (B) PLATES, CYLINDERS AND OTHER PRINTING COMPONENTS; PLATES, CYLINDERS AND LITHOGRAPHIC STONES, PREPARED FOR PRINTING PURPOSES (FOR EXAMPLE, PLANED, GRAINED OR POLISHED) This heading includes : (1) Relief or intaglio plates en raved by hand, mechanically or by acid. These may be of wood, liuolewn, copper, steef, etc. (2) Lithographic stones. The illustration is either hand-drawn or photographically transferred and prepared with acid. (3) Offset printin plates of zinc or aluminium or similar flexible metal sheets on which the design is repro uced in the flat, i.e., neither in relief nor intaglio. I (4) Engraved or etched cylinders. (5) Plates and dies for relief stamping or printing, e.g., for machines which emboss, with or without also inking, letter heads, visiting cards, etc. Provided they have been treated so as to render them suitable for engraving or impressing, lithographic stones, metal plates and cylinders, even though not engraved or impressed, are also included in this heading, e.g., : (6) Planed or grained lithographic stones. (7) Metal plates or sheets prepared for engraving (by planing, graining or polishing). (8) Perfectly polished or grained surface metal cylinders. These cylinders, usually of cast iron, are enerally electroplated with copper, or else have a copper covering consisting of assemble removable sleeves. f (9) Metal or plastic masters for use on office-type offset printin machines. The to edge of the sheets has usually been processed to permit attachment to &e drum ofthe macLe. Sensitised plates (e.g., consisting of metal or plastics, coated with a sensitised photographic emulsion, or of a sheet of photosensitlve plastics, whether or not affixed to a support of metal or other material) are excluded (heading 37.01). PARTS Sub'ect to the general provisions regardin the classification of parts (see the General Exp anatory Note to Section XVI), the hea8ing also covers parts of the machines of this heading. The heading also excludes (a) Stencils of zinc, plastics, cardboard, etc., for use in stencil printing machines (classified according to the constituent material). (b) Copying or transfer papers, bearing texts or designs for reproduction (heading 48.16). (c) Silk screens for silk screen printing, whether or not coated (heading 59.11 metal wire cloth, mounted on a fiame, whether or not prepared, for use in screen printing (classi!I led according to the constituent material). (d) Marking irons for gilding machines (heading 84.40). (e) Metal, stone or wood working machine-tooh and water-jet cutting machines (for exam le, matrix planing and finishing machines; machines for planing and cuttlng rules; disc or baf'1 graining machines; engraving machines; milling cutters; routing machines; trim saws) (headings 84.56 to 84.65). (f) Type and other rinting parts of typewriters, calculating or other machines of headings 84.69 to 84.72 (heading 84.73f (g) Moulds (heading 84.80). (h) Laser photo lotter for creating latent images, on photosensitive film, generally from digital formats, by means o?a laser beam (heading 90.06). (ij) Measuring or checking instruments (heading 90.17 or 90.31). -
