  • This invention relates to printing plates and to a method of producing the same. More particularly the invention relates to printing plates of high quality having sharply defined contact surfaces.
  • the contact surface of the electrolytically deposited film is the surface which was formed in contact with the mold and accordingly is a positive reproduction of the origins;
  • the back of this electrolytically deposited film is, after stripping, tinned and then backed with a type metal.
  • the contact surface may if desired be provided with a chromium plate which enhances the wear resistance of the plate.
  • the mold of the prior art may consist of lead but such is generally considered undesirable due to the weight of the material and the necessity for frequent handling.
  • the electro type plates may be formed by pouring into the papier-mache mold molten lead which when set is stripped from the matte backing and utilized in the printing process. While adapted for high speed production such a process, due to the inability of lead to form very sharp configurations, is inadequate where very high quality printing is required. Further such plates are of course difficult to handle due to their weight, and also lead is relatively soft and does not possess great wearing qualities.
  • the thickness of the deposited metal film may be readily controlled and is preferably in the range of about 0.001 of an inch to 0.005 of an inch, the control preferably being exerted through control of the volume of carrier gas supplied per unit of time to the mold.
  • the apparatus containing the mold workpiece is provided with spaced ports through which the gaseous compound enters, the ports being so located as to provide a uniform metallic deposit over the exposed mold surface.
  • the metal deposits from the vapor in very fine particles and enters the smallest of recesses in the mold surface and the deposited film is of such a structure as to retain its form when the film is removed from the mold after completion of the plating operation.
  • Release of the metal film from the mold in the case of papier-mache may be effected by soaking the same in water or in water containing a wetting agent, and in the alternative the papier-mache may first be treated with a silicone solution to aid the release of the metal film.
  • a silicone solution to aid the release of the metal film.
  • Normally plastic surfaces will not require a mold release agent and metal films may be removed therefrom directly, and this is also the case where the mold material is of lead, although in given instances mold release agents known to the art may be used as required.
  • the surface of the nickel film which bore against the mold surface may have a light film of chromium applied thereto in order to improve the wear resistant qualities of the plate.
  • a backing for example of type metal, may be applied in order that the completed plate may withstand the pressures to which it is subjected when in use.
  • the product of invention consists of a film of nickel accurately formed to the contour of the mold from which it is produced, the metal film being backed with a thickness of a strengthening material to permit it to withstand the pressures applied in the printing processes.
  • the inventive process consists in the deposition of metal from the gaseous state upon mould sections having sharply diverging lines or printing characters such as are found on printing blocks and the formation of a of sufficient coherency to withstand the applied pressures in the use of the film when combined with a metal backing material.
  • FIG 1 illustrates schematically apparatus useful in the production of the plate of invention
  • Figure 2 is an elevational view of the plate ofinv'ention
  • Figure 3 is a flow chart indicating the steps of the process of invention.
  • Figures 4, 5 and 6 are flow charts indicating the steps in the specific embodiment of the invention.
  • FIG. 1 a tank of inert carrier gas such as carbon dioxide which tank is provided with a valve 2 and a fiowmeter 3 in line 4 which passes from the tank 1 to a carburetor 5 immersed in oil 6 contained in tank 7 which oil and carburetor are maintained at a constant temperature by means of heater 8 and the thermostat unit indicated generally at 10.
  • inert carrier gas such as carbon dioxide
  • Tank 7 is provided with a stirrer 12 driven by a motor 14 through belting 16.
  • a line 18 which passes through pump 20 to a chamber 22 in which there is secured a metal plate 24 insulated from the walls by support members 25.
  • a conduit portion 26 Extending into the chamber is a conduit portion 26 having therein apertures 28 facing member 24.
  • a water jacket 30 Surrounding the chamber 22' is a water jacket 30 provided with an inlet port 32 and an outlet port 34. Adjacent the water jacket 30 and outside of the chamber 22 is an inductive heat source in the form of a coil 36 electrically connected with a power supply (not shown).
  • the remote end of the chamber 22 is provided with a removable cover 38 for the insertion of specimens to be plated upon the plate 24.
  • This cover is provided with an aperture through which extends a conduit 40 and which terminates in a trap 42 surrounded by cooling Water 44 flowing through tank 46 through inlet 48 and outlet 50.
  • the carrier gas for instance carbon dioxide
  • the carrier gas for instance carbon dioxide
  • the carburetor 5 where the nickel bearing compound is vaporized and entrained and carried to the plating chamber.
  • the plating gas issuing from the apertures 28 in the conduit extension 26 deposits on the mold, as for example a papier-mache, which is heated directly by its contact with plate 24, the plate itself being heated by means of current applied to the induction coil.
  • Gases which are not decomposed and those gases which are decomposed pass out through the remote end of the chamber to the trap 42 wherein the metal components are cooled and deposited, while the vapor portion including carbon dioxide formed pass out to the atmosphere.
  • Example 1 Mold of papier-mache Temperature 260 F. Carburetor temperature 50 F. Rate of carrier gas flow 0.5 liter per minute. Rate of metal depositionruu .0002 inch per minute. Thickness of plate .001 of an inch. Plating time Approximately 5 minutes. Plating gas Nickel carbonyl and carbon dioxide carrier. Mold size 4" x 4'.
  • Example 11 Mold or papier-mache Temperature 280 F. Carburetor temperature 70 F. Carrier gas Carbon dioxide. Rate of carrier gas flow 20 liter per minute. Rate of metal deposition .0015 inch per minute. Thickness of plate .005 of an inch. Plating time Approximately 3 minutes. Plating gas Nickel carbonyl and carbon dioxide carrier. Mold size 4" x 4".
  • Example IV Lead mold Temperature 350 F. Carburetor temperature 75 F. Rate of carrier gas flow 15 liters per minute. Rate of metal deposition--- .0010 inch per minute. Thickness of plate .005 of an inch. Plating time Approximately 5 minutes. Plating gas Nickel carbonyl and carbon dioxide carrier. Mold size 4" x 4".
  • the plating chamber is cleared of oxygen and other gases prior to the raising of the workpiece to the plating temperature by simply passing a flow of carbon dioxide through the chamber or a flow of plating gas through the chamber.
  • the nickel plates secured by following the procedure in each of the examples set forth hereinbefore may be tinned on the reverse side and backed with a heavier metal, for example a type metal, in order that the metal plate may withstand the pressures applied in the course of the use of the film.
  • a heavier metal for example a type metal
  • the contact face of the plate may be provided with a thin layer of chromium in order to increase its wear resistant qualities. Since the ranges set forth in the specific examples are considered to be optimum conditions it should be noted that where the mold is of papier-mache the temperature of the mold may be suitably between 200 and 300 F. and where of lead between 200 and 400 F., while the plastic molds may be subjected to temperatures of from about 200 F. to just below their distortion temperature.
  • the carburetor temperatures which are useful may vary from 32 to 104 F. with the carrier gas flow rate of 0.5 liters per minute to 20 liters per minute.
  • the mold should be heated to at least 200 F. and the temperature should always be below the distortion point of the material used.
  • the flow rates and the plating rates are not critical, but as indicated in the examples may be between about 5 liters per minutes and from about .002 inch to .0015 inch per minute, respectively.
  • Plastics from which molds may be suitably prepared include thermosetting resins, such as the phenol formaldehydes and urea melamines, as well as the thermoplastics including the vinyls such as vinyl chloride and vinyl acetate; but the invention is considered to be suitable for any plastic material which will withstand at least 200 F. temperature without distortion and is considered to be suitable in the process of invention.
  • the depth of the impression in the mold surface has no critical limit so far as is presently known it being necessary only to provide sufiicient deposit of nickel to fill the impression and attain in addition a thickness of .001 to .005 of an inch in the body of the nickel plate. Normally however with deep impressions it is advisable to apply a heavy body, that is .005 of an inch thick in order to body the product uniformly.
  • the impressions on the nickel plate are exceedingly sharp for recessed as well as the raised indicia as the metal deposited from the vapor state apparently clings compactly to the mold surface which it strikes whether the mold impression be upraised or recessed.
  • the nature of the plastics useful in the molds required mason for the inventive process is not critical the only requirement being that the material does not soften at the minimum temperature of 200 F. required in the process for decomposition of the nickel carbonyl.
  • the gas pressure within the plating chamber may vary over a wide range from slightly above atmospheric to pressures as low as 40 mm. of mercury. At the lower pressures considerable precaution should be taken to prevent leakage of air into the system as the presence of oxygen would tend to affect the coherency of the deposited coat deleteriously.
