Definitions

  • ABSTRACT A dye transfer apparatus having a stain preventing device.
  • the apparatus comprises a rotatable plate cylinder on which a matrix is mounted, a dye solution applying device for applying a dye solution on the matrix, a washing liquid supplying device positioned downstream of the dye solution applying device, a squeeze roller positioned downstream of the washing liquid supplying device for urging a receiving material into contact with the matrix, and a washing liquid removing device having a head with a narrow tip end disposed closely adjacent the nip of the plate cylinder and the squeeze roller to remove washing liquid containing dye from the surface of the receiving material.
  • the present invention relates to a dye transfer apparatus for making a number of duplicates from an original by the use of a matrix mounted on a plate cylinder which is provided with a stain preventing device.
  • the dye transfer process is a process for duplicating a dye image on a material to be dye transferred by dyeing a plate, which is called a matrix, absorbing dye or dye solution in an image pattern thereon, and then transferring the dye image on the matrix to a base (hereinafter referred to as receiving material) having a dyeable layer thereon by bringing the receiving material into contact with the matrix.
  • a base hereinafter referred to as receiving material
  • the matrix is generally used as one set consisting of three matrices, each having a monocolor image corresponding to the element of the tricolor separation images.
  • processes for preparing the matrix namely, a dichromatic acid photohardening process and a tanning development process.
  • the former is a process in which the absorbability of the matrix is varied by photohardening in a gelatin layer thereon, and the latter is a process in which the unhardened part of the gelatin layer is washed away with warm water and the remaining gelatin relief is dyed with dye solution so that a dye image may be transferred to a receiving material.
  • the former is a lithographic process and the latter is a reliefprinting-like process.
  • the former is suitable for obtaining a positive duplicate from a positive original since the amount of the light absorption by the dye is reduced in proportion to the magnitude of the light
  • the latter is suitable for obtaining a positive duplicate from a negative original since the gelatin relief absorbing the dye is increased in its height in proportion to the magnitude of the light.
  • the problem of whether the duplicate is negative or positive is, however, not a serious problem in the present invention, since the negative image can easily be changed to positive image and vice versa.
  • One set of the matrices prepared as describedabove is-used one by one to transfer the dye image to a receiving material to form a color image thereon. In this case, the monocolor dye images transferred to the material should all be in alignment with each other so that a sharp color image maybe formed thereon when the material is transferred with the different monocolorimages.
  • the dye transfer process which has been put into practice consists of four minor processes, namely, (1) a matrix preparing process in which monocolor matrices are made out of a color slide or color negative film; (2) a dye process in which the matrices are dyed; (3) a washing process in which excessive dye solution is removed from the matrices; and (4) a transferring process in which the matrices are brought into contact with the receiving material to transfer the dye image from the matrices to the material.
  • a matrix preparing process in which monocolor matrices are made out of a color slide or color negative film
  • a dye process in which the matrices are dyed
  • a washing process in which excessive dye solution is removed from the matrices
  • (4) a transferring process in which the matrices are brought into contact with the receiving material to transfer the dye image from the matrices to the material.
  • the dye transfer process is economical compared with the color printing process in which a photographic paper is exposed and developed one by one for every duplicate, since in the dye transfer process the silver halide photosensitive material is only required to make the first monocolor relief and the rest of the duplicates can be obtained only by the use of the receiving material having a mere gelatin layer. Further, the dye can be selected regardless of the harmful effect to the photosensitive material. Therefore, a bright and fast dye can be used. As a matter of fact, the brightness of the color obtained by the dye transfer process is superior to that obtained through the photographic color printing process.
  • the dye transfer process is advantageous in economy and brightness of color.
  • the dye transfer process is not as yet extensively used. The main reason for this is considered to be the great labor and time required thereby and unsuitability for mass production.
  • the dye transfer process has been conducted manually except in the case of using an apparatus embodying it.
  • an elongated strip of plastic matrix having accurately provided perforations in the longitudinal direction is fed together with an elongated strip of plastic material serving as a receiving material so that the dye image on the matrix may be transferred to the material while both are fed together in contact with each other.
  • This type of automatic dye transfer apparatus is used in the field of motion pictures.
  • the matrix and the receiving material are easily regulated so as to be in accurate alignment with each other and fed together. Due to such ease, an automatic apparatus can be em bodied for this type of matrix and receiving material.
  • the dye transfer apparatus in accordance with the present invention neither the matrix nor the receiving material is required to have perforations since the driving means for feeding the matrix is completely different from the conventional apparatus.
  • the dye transfer apparatus in accordance with the present invention is provided with a means for preventing the receiving material from being stained.
  • the material may be of any type, such as plastic, paper which absorbs water, and so forth.
  • the process is carried out as follows.
  • the matrix which is dipped in the washing liquid after dyeing is picked up with tweezers or fingers covered with a rubber glove and brought into contact with a receiving material placed on a planebase by means ofa press roller in a manner in which the air and washing liquid remains between the surface of the matrix and the surface of the material.
  • the amount of the washing liquid has a very important relation to the quality of the transferred image obtained on the receiving material;
  • the washing liquid serves not only to remove the excessive dye from the matrix but also insures'that the matrix is-in good contact with the material. That is. if the amount of the washing liquid is too small, the removal of the air cannot be conducted sufficiently and causes the image to be provided with spots where the dye image is not transferred. If the amount of the washing liquid is too large and the large amount of washing liquid is not removed well with the roller, a thin layer of the washing liquid remains between the matrix and the material, which results in a reduction in dye transferring speed and unevenness in dye transferring density or optical density shortage.
  • the washing liquid which is required to exist between the matrix and the material to be dye transferred for insuring good contact between them, is required to be well removed from the area between them when the dye image on the matrix is transferred to the material.
  • the washing liquid is removed manually, it is removed from the surface of the material at an end thereof with a press of squeeze roller.
  • the removal of the washing liquid has another purpose other than to insure good contact between the matrix and the material. That is, the washing liquid is re moved to prevent stain.
  • the washing liquid which is at first transparent and has no color, is colored with the dye when removing the dye. Therefore, the colored washing liquid causes the image to be stained. Accordingly, the colored washing liquid is required to be removed completely and quickly.
  • a matrix with perforations and a receiving material with perforations are dipped in the washing liquid in contact with each other to prevent air spots on the surface of the receiving material and, at the same time, to remove the colored washing liquid by diluting it with the environmental fresh washing liquid.
  • the principal object of the present invention is to provide a dye transfer apparatus in which the above two problems are solved with respect to an apparatus for making a plurality of duplicates automatically.
  • Another object of the present invention is to provide a dye transfer apparatus for making a number of duplicates through a dye transfer process with a matrix mounted on a plate cylinder which is provided with a stain preventing device.
  • Still another object of the present invention is to provide a dye transfer apparatus in which the washing liquid is quickly and completely removed from the surface of the matrix.
