Definitions

  • a subtractive presensitized offset printing plate may be developed by what is known as the hand developing process.
  • the carrier which is usually a thin sheet of aluminum, is first coated by the manufacturer with a light-sensitive coating usually containing, among other things, one or more resins, and the plate is then sold in the presensitized condition to the customer.
  • the customer exposes the printing plate through a stencil to a source of strong light, such as a carbon are for example.
  • a source of strong light such as a carbon are for example.
  • the lightsensitive coating when subjected to such a light is converted in such a manner that, after development, the image areas are retained on the plate surface and the non-image areas are removed.
  • the plate After development, for example by rubbing a developing agent into the surface of the plate by means of a sponge, the plate may be fixed and/or washed and, finally. a coating of gum arabic or similar material is applied to the surface of the plate to protect the image free areas thereof.
  • the plate is then ready for the printing press.
  • the printing member thus prepared is then subjected to a developing operation using the chemistry prescribed by the manufacturer of the printing member.
  • This chemistry is worked into the exposed coating by hand rubbing, for example with a sponge, until the nonimage areas are subtracted or removed from the carrier leaving an exact replica of the image on the plate carrier.
  • the printing member is then fixed and/or washed and a solution of gum arabic, or a similar solution, is applied to the plate surface, resulting in a printing plate which is ready for the press.
  • the present invention overcomes the difficulties associated with conventional hand developing of a plate coated on one side only by providing a novel dispensing apparatus for lithographic developer.
  • the dispensing apparatus avoids changes in the processing solutions by a unique method of metering the processing fluids in controlled quantities onto the plate surface without damaging the plate surface, rendering it possible to economically use the processing solutions only once, and without smearing or dragging used solutions into fresh solutions or onto adjacent plate areas.
  • fluid is pumped under pressure into a manifold, which may have a width of about one inch and a height of about one-half inch.
  • a plurality of apertures dispense the fluid, under pressure created by a pump, into a second bar which has a width of about one inch and a length corresponding to the width of the machine.
  • the bottom bar contains a slot which may have a width of about 1/16 inch, for example.
  • the bar is made of plastic so that it does not scratch the surface of the plate in contact therewith.
  • the entire assembly is spring-loaded and rests on a backup plate made of hard rubber.
  • a pair of nip rolls transport a plate into a developing station and between the backup plate and the dispensing apparatus.
  • the pump pressure forces a quantity of developer into the slot in the dispensing apparatus and, since there is a backup plate facing and in contact with the spring-loaded bar of the dispensing apparatus, the slot in the bar fills with developer prior to the entrance of the plate and causes a slight rising of the entire assembly, by about 0.015 inch. with little or no outflow of the developer. This rise, in turn, allows the plate to enter between the bar and the backup plate without actually contacting the dispensing apparatus.
  • the moving plate receives fluid developer from the slot in the bar and carries the developer away, the developer is constantly replaced from the manifold as a result of the pressure of the pump supplying developer from the reservoir. Simultaneously, this continuing feed of developer maintains the dispensing assembly above the surface of the plate to be developed and the inverted menicus created dispenses a minimum coating of developer, regulated by the pressure of the feed pump, uniformly upon the plate.
  • a reciprocating rubber squeegee assures that the developer is adequately rubbed into the surface of the plate.
  • the action thereof can be made rather rapid so that shortly thereafter it can be squeegeed off and drained away into a waste disposal by a pair of squeegee rolls.
  • a second application of developer may be applied in a similar mechanism.
  • a third similar mechanism can be employed to apply a fixing solution, if necessary, for the proper preparation of the plate. This may be combined with a rubbing action of a piece of velour-like material reciprocating transversely to the direction of plate travel at a rate of about 175 strokes per minute. in a stroke of about one-half inch.
  • the plate then enters a washing station and a lacquering station, if required, followed by a second washing or gumming station before exiting from the apparatus as a completed plate ready for the printing press or for further work prior to going to the printing press.
  • FIG. I is a schematic view of a processing line for processing printing plates precoated on one side only
  • FIG. 2 is a perspective view of a portion of the processing line of FIG. 1 showing the developer dispensing apparatus
  • FIG. 3 is a sectional view taken on line 33 of FIG. 2 and looking in the direction of the arrows.
  • a planographic printing plate sensitized on one side and imaged by exposure to a desired master is inserted into the processing line at the point of the arrow 2.
  • the inserted plate passes over the trigger mechanism 4 and thus actuates the entire processing line, i.e., the feed rolls as well as all transportsqueegee rolls begin rotating.
  • pumps connected to the various chemical supply tanks, not shown begin operating and dispensing chemistry as required.
  • the developer dispensing apparatuses or heads as well as the rinse-scrubber head begin reciproeating.
  • the plate passes through a pair of feed rolls 6, which rolls pass the plate between the first developer dispensing head 8 and its associated support rail 10, and a controlled amount of developer at a controlled temperature is dispensed from the developer dispensing head 8 onto the plate surface and carried away.
  • This amount can be regulated by adjusting the pressure in the developer supply line by setting a bypass, not shown, and a volume regulator which will be described below in connection with FIG. 3.
  • the plate then passes through a first set of transportsqueegee rolls 14 which rolls transport the plate into the second developer dispensing assembly 16 having an associated backup plate 18.
  • the construction of the second developer dispensing assembly 16 and its associated backup plate 18 is identical with the construction of the first developer dispensing head 8 and its associated backup plate 10.
  • the second developer dispensing head reapplies a fresh amount of developer solution in the same manner as the first developer dispensing head 8.
  • the plate then reaches a second pair of transportsqueegee rolls 20 which remove all excess developer and, in turn, propel the plate under the rinse-scrubber head 22 which removes residual developer from the plate before it enters the third transport-squeegee roll assembly 24.
  • the latter rolls advance the plate under the gum dispensing tube 26 and into the transportsqueegee rolls 28, which latter move the plate between the air dryer tubes 30 and into the exit rolls 32 which, in turn, propel the developed, gummed and dried planographic printing plate out of the processing line ready to be mounted on a press.
  • a plate 34 is shown as it passes between the feed rolls 6 and under the first developer dispensing head 8.
  • developer is supplied through the developer line 36 and the dispensing head is reciprocated transversely to the direction of plate travel by means of the reciprocator shaft 38.
  • the dispensing head is shown in more detail in FIG. 3.
  • the dispensing head includes the bottom bar 40 which abuts against the hard rubber surface 42 of the backup plate 10 when no plate is received between the two.
  • the bottom bar 40 has a slot 44 therein which extends across the length of the bottom bar 40 but not completely to the ends thereof, so that developer pumped into the slot cannot run out of the ends thereof.
  • the developer is supplied to the slot 44 by means of the passage 46 which connects to the reservoir 48 in the manifold 50.
  • the reservoir 48 is connected to the developer supply line 36 by means of a bore in the rod 52.
  • the rod 52 slides freely in the supporting bracket 54, to which the reciprocator shaft 38 is connected by the machine screws 56, and the entire assembly is reciprocated by the shaft 38 connected to a reciprocating apparatus, not shown.
  • the bar 40 which may be made of plastic, is biased against the surface of the plate 34 by means of the spring 58 and any degree of pressure desired may be obtained by balancing the spring pressure against the pressure of the developer supplied to the slot 44.
  • the volume of developer supplied to the slot 44 may be regulated by the developer supply volume regulator 60 having a hand wheel 62 thereon.
  • the supply volume regulator is of conventional construction and, accordingly, will not be further described.
  • the entire processing line is enclosed in a housing, not shown.
  • the processing line is intended to be used with fresh chemistry at all times, i.e., there is no recirculation. By so doing, all parameters are maintained constant and since, in addition, the temperature of the developer is controlled to within 5F., processing of printing plates is predictable and reproducible.
  • a dispensing apparatus for lithographic processing fluids comprising; bar means adapted to extend across a printing plate to be processed, having a single outlet means comprising a slot in that side of said bar means facing said plate to be processed and an inlet means in fluid communication with said outlet means, mounted to move perpendicular to the surface of said plate to be processed and normally biased toward the side of said plate to be processed; means for supplying processing fluid, under pressure sufficient to overcome the biasing of said bar means and move said bar means away from the surface of said plate to be processed; and means for reciprocating said bar means transversely to the direction of travel of said plate to be processed.
  • a dispensing apparatus including spring means biasing said bar means toward a plate to be developed.
  • a dispensing apparatus including spreader blade means secured to said bar means.
