Definitions

  • the invention relates to a method for processing color proofs as well as to the device for implementing this method, whether for films or papers.
  • the processing of color paper requires a total absence of light, a developer temperature constant at half a degree.
  • the least expensive machines but of lower output, consist of a tank inside which turns a drum carrying the proofs, the tank being emptied automatically after each bath. This process has the drawback of operating in a lost bath, the quantities used being quite large due to the dimensions of the tank.
  • the method for processing color proofs, films or papers which is the subject of the invention is characterized in that the products necessary for the treatment are poured beforehand into contiguous capacities, the test being arranged in a terminal capacity, and in that that each bath change operation of the terminal capacity is effected by simultaneous transfer of the baths of a capacity to the contiguous capacity which follows it by simple momentary tilting of all of said capacities, the bath of the capacity containing the test being evacuated during the transfer operation with a view to replacing it by returning the assembly to the initial position.
  • Another object of the invention is a device for implementing said method, characterized in that it comprises a compartmentalized and tiltable body, each intermediate compartment of which comprises an orifice for introducing a determined bath and an internal cup, the opening is oriented in such a way that it fills in an inclined position of the body only by pouring the preceding compartment through an orifice in the internal wall separating the two adjoining compartments and does not empty into the compartment which contains it only when the body returns to its non-inclined position.
  • Another object of the invention is a device of this type, the last compartment of which includes any device for introducing the test to be treated and a bath discharge orifice provided with baffles against the penetration of any light so that the The whole device, after charging, can be operated in the light. It is therefore sufficient, after having introduced the test to be treated in the last compartment, to pour in light the successive baths from the first to the penultimate compartment and to carry out a first tilting followed by returning to the initial position so that the first bath is introduced into the compartment containing the test then wait for the necessary time provided for the first bath and operate a second tilting so that the first bath drains and is replaced by the second when returning to the initial position .
  • Such a characteristic also makes it possible to take advantage of the rotational movement that is given to the body tilting around its axis to further reduce the size without the risk of return of small fractions of the bath that has just been spilled during a tilting of the body by partially closing the buckets and equipping them with at least one internal blade discharging the product contained in the bucket during the rotation of the body in the non-tilted position.
  • the whole body being responsible for all of the treatment baths, we take advantage of the compactness of the assembly and the rotary movement to maintain the temperature of the baths by partially immersing the tilting body in a water bath maintained at constant temperature, the body being equipped with small longitudinal vanes so that they maintain a small layer of water, constantly renewed, of given temperature.
  • the device is permanently protected by a layer of water whose temperature variation during its training is much less than the variation sudden temperature of the environment outside the water bath.
  • the method and the apparatus thus defined can be used in very many ways.
  • the method applying in particular to positive papers for the color reproduction of a document which is strongly illuminated on a reproduction bench the implementation device can be adapted to the treatment of this kind of paper.
  • FIGS. 1 to 3 The device for implementing the method of treatment by simultaneous transfer of the baths necessary for the treatment of any test is illustrated in FIGS. 1 to 3.
  • the device consists of an elongated body 1 provided with a number of intermediate compartments 2, 3 and 4, a terminal treatment compartment 5 and a terminal compartment 6 for receiving the last treatment bath.
  • the compartment 5, possibly removable, is provided with any device for introducing the test 7 to be treated. It can in particular be a positive or negative paper which must be treated in accordance with the color process and the products used.
  • the device may further include an eccentric 29 driven by the drive shaft 28 so as to ensure the tilting of the body 1 from the state shown in FIG. 1 to that of FIG. 2.
  • an eccentric 29 driven by the drive shaft 28 so as to ensure the tilting of the body 1 from the state shown in FIG. 1 to that of FIG. 2.
  • the bath 11 having reached the compartment 5 where the test is located 7 it suffices to leave the test in contact with the bath for the required time before triggering a new tilting of the tank.
  • the liquid 11 flows through the baffles 30 from the end of the terminal compartment 5 to be evacuated in the container 31 disposed on the support 32.
  • the baths 8, 9 and 10 pass respectively into the cups 25, 26 and 27, so that after returning to the horizontal position the test 7 is in contact with the bath 10.
  • a new command of the eccentric 29 causes the evacuation of the bath 10 and its replacement by the bath 9.
  • test 7 can be withdrawn after a determined period.
  • the elongated tank thus formed can be driven in a rotational movement around its axis in order to sweep without undue agitation the surface of the treated paper.
  • each bucket having the shape shown in FIG. 4,
  • the wall 33 of the compartment is conical. It also includes a conical inner wall 34 constituting the wall of the bucket itself. The latter is maintained at a certain distance from the wall 33 by means of spacers 35.
  • An end partition 36 perforated in its center37 allows the bucket 34 to still retain the liquid received after returning from the tank 1 in a horizontal position.
  • a longitudinal triangular blade 38 makes it possible, during the rotation of the tank, to pour the products received through the orifice 39 of the external wall of the preceding compartment, into the compartment corresponding to the bucket 34.
  • the wall 34 can for example be provided with helical threads to empty this bucket during rotation.
  • the temperature control device has been shown diagrammatically by the resistors 49, the bottles containing the various products used have been represented diagrammatically at 50.
  • the end face 51 of the tank has been shown in order to show a series of small longitudinal vanes 52 s' extending over the entire length of the wall of the tank. They make it possible to draw around the tank a real protection of water preserving the wall of sudden variations in temperature between that of the bath and that of the ambient external region, thus considerably improving the maintenance of the internal temperature of the partitioned tank.
  • the apparatus described can be compact and thus constitute a device for developing portable color photocopiers.
  • FIGS. 7 and 8 show an arbitrary lens 53 on an exposure bench 54.
  • a frosted glass 55 makes it possible to focus on the desired image.
  • the casing 57 of the cassette 56 is dragged in place of the frosted glass 55 as shown in FIG. 8.
  • This casing contains the paper to be exposed.
  • the cover 58 made of a slide or a curtain is reintroduced into the case 57 in order to close the cassette 56 again.
  • This may or may not be of the recoverable type, and contains only materials unassailable by the baths.
  • it is the cassette 56 containing the exposed test which is placed in the compartment terminal 59
  • the flat bottom compartments 60, 61, 62 and 63 receive the rinsing water, the fixer, the bleaching bath and the developer respectively. These products are discharged daily above the partitions 76 to 79 of the compartments at points 64 to 67 in front of each bucket 71 to 74.
  • the table 68 may include, as the case may be, automatic equipment making it possible to tilt the together 80, this equipment can be controlled by an appropriate programmer.
  • the developer introduced at 67 passes from the compartment 63 into the bucket 74 then, when returning to the horizontal position, in the terminal compartment 59 containing the cassette 56.
  • This may in addition to the conventional slide , passages provided with baffles against the penetration of light but allowing the developer to easily travel over the entire surface of the paper it contains. These passages can be formed for example on the sides 70 and 71 of the cassette.
  • the cassette 56 has been shown in FIG. 10 with the test 75 in the position it occupies when it is placed in a development compartment in accordance with the method. It can be seen that the spaces 70 and 71 between the cover 53 and the box 57 containing the test 75 allow the liquid to penetrate into the cassette and to be evacuated from it when it is tilted during the tilting movement of the device 80.
  • FIG. 11 shows at 88 the path of the bath 89 during the successive tiltings of the tank 90 around the axis 91.
  • the lines of intersection 92 of the partitions separating two compartments 93, 94 located substantially on either side other of the axis 91 constitute natural directions of flow alternately channeling the bath towards the openings or baffles 95 giving access to the compartments 94 then towards the openings or baffles 96 giving access to the neighboring compartments 93 but offset longitudinally.
  • the baffles can be presented in particular in the form of pouring spouts or small inclined planes.
  • the last baffle 96 gives access to the receptacle containing the test by means of a conduit receiving the successive baths by gravity, the receptacle emptying before reception of a new bath.
  • any device for introducing film or paper proofs into the terminal capacity which may or may not be removable, can be provided.
  • the supports and guides inside the terminal capacity so as to receive a determined number of tests of identical or different format.
  • the guiding device can be designed for the development of any image support for paper, films or photographic films, for example, these being loaded into any suitable device.
  • the receiving tanks of these image carriers are preferably modular so as to process different formats with the minimum of product.
  • the temperature regulation device which has been shown diagrammatically by the resistors 49 may comprise any particular safety device: triggering of the battery power supply in the event of a breakdown, the resistors 49 being distributed to obtain perfect regulation taking into account the movement of water in the tank 31.
  • This may in particular include partitions intended to regulate the flow of heated water and to avoid mixing the water to be heated too quickly with that being at the desired temperature.
  • the partition 82 prevents the water flowing from the blades 52 from returning to the part 83 without passing into the heating zone. This communicates with the part 83 through the passage 84 left at the bottom of the wall 82.
  • cassettes provided with a usual safety means such as 85 preventing its opening, additional baffles preventing the penetration of light into places 70 and / or 71 allowing circulation of the treatment product.
