The invention relatesto improvements in dye printing photographic processes in which matrix films representing textgtone or color partlvalues are first provided with transferable coloring substances and then printed in register or special alignment on 'a blank. The invention concerns the registration step in regard to when and how the course of the reproduction process. In combination with old steps the invention greatly' simplifies the mechanical reproduction and is particularly suitable for color photography. By permanently combining in a unit tangible elements at a, certain stage of the process the new step is materialized in a product.

One of the. purposes of. the invention is. to

. eliminate the use of auxiliary devices for registering matrix films or part images printed in different blanks.

such step can be performed with advantage in;

picture but; for all the pictures produced from said matrices which are printed, washed, dried and filed forfuture use in such bound condition, so that not onlya registering device but the registration itself is further unnecessary.

'Another purpose of the invention is the pro tection of the delicate matrix films'during their handling for it saves them from scratches and other common accidents.

manently attached margins do not permit any sliding which could result in harmful friction.

This is particularly important when the matrices after printed are filed for future use, as it is well known that old loose matrices are usually worthless and ruined. When the matrices are Thispurpose is attained by producing the printing. matrices on a material having an elastic support, providinga sufficient margin at one end of the matrices, bringing the matrices into register, and then permanently attaching said matrices atsaid margin in book- "like form, as for instance by soldering or rivetin'g once and for all the printing matrices to each other.' Due to the elasticity of their support and the margin left the film matrices though attached in register permit enough separation for their inking and for inserting'the printing blank and produce the picture in known manner. This new permanent registration, cannot be practiced when the matrices are all produced in material of rigid support, as ordinary plates, andis also unapplicable to. the production of cinematographic length of film for in this case matrices and blank have the same width and no margin can be provided. But such limitations are unimportant because Celluloid supported films have practically ousted todayphotographic plates and.

because the moving picture production rather requires auxiliary devices for a great output in a the, ordinary photographer or amateur who cannot afford an'installation including registering devices 'of great precision to I produce a small number of pictures.

' Another purpose of the invention is the saving of time. In two colorwork, for instance, whether two matrices or two blanks bearing different part images have to be registered, thatoperation, either by machine or hand, must be repeated for every picture and in thelast case the blank .must also be glued. While according to the invention two. matrices permanentlybound face. to face, and registered once, will print part ,records in. register on opposite sides of a transparent double coated support as many times as desired in a single and final operation. The registrasort of mass production of pictures. The advan- T tages of the new step are however, priceless for three, I assemble one pair face to face and the or extra piece of plain Celluloid for protection. If only transparencies wer'to be printed the odd matrix could be protected by the back of one of the pair, but for all purposes I prefer .toadd otherface out but facing an auxiliary element the extra protecting cover.

Another purpose of the invention is to provide ,a' system of registration suitable not only for two but for three or four color work. I--may use a blank formed by two separate elasticv elements whichI attach or-solder exactly as I do with the matrices at one margin. It must be observed that I do not use a marginally soldered pair of blanks for two color work'where a double coated single blank is sufiicient'but for producing three or-four color pictures. It must alsobe noticed that the two'element blank which-,1 use for three ,or four color work is formed asexplained by two separate, parts and that these parts are bound as the matrices. Only in that condition they registration is dependable for as it is well known the position of a plane is determined by three .points' and, when two elements are soldered or riveted, the attached sections occupy enoughsurface to secure the position of the printing planes. In other words, the matrices or the two bound blanks can be partially separated because soldered and fastened to each When the matrices are two, assembled face to face, the images are inside and the bare Celluloid out, while the pertached matrices with; a protecting fourth element'.

Although the invention is suitable for different methods of dye transferring and capable of serving different purposes in mechanical printing, we

support of Celluloid. As shown in the figure the complementary part images are printed so that they maybe brought in register when the gelatine sides of both matrices are facing each other.

Those reliefs are produced with a sufficient margin for the soldering shown in Fig. 2. I practice this by wetting and brushing away part of the gelatine in contacting sections at one end of both reliefs, and after bringing the images in register I carefully apply to the bare Celluloid of both elements the well known fihn cement, 5. man equivalent. I may also place between the soldered margins an auxiliary element consisting of an intermediate strip of Celluloid 6, Fig. 7, to which both matrices are soldered in order to separate the printing planes in the thickness of the blank. This soldering of course can be performed by other means as rivets (5b), eyelets (5a) or any suitable means that would firmly and permanently bind the matrices at the margin and preserve the registration without interfering with a partial separation of the matrix films as the leaves of a book.

For the coloring of the bound matrix films any known means with some suitable modifications may be used, as a two cell tank having the complementary coloring solutions separated by a partition, the margin allowed in the matrix films permitting to interlock said partition between the bound matrices and thus selectively dye each one with a difierent color.

- I prefer however, ,to apply the dyes in another form and by either one or two new methods of my invention which I have successfully practiced. Besides being equally efiicient and far superior from several points of view to the old dyeing bath system, those methods present a particular advantage for the coloring of bound matrices in color photographic reproduction, and that is that the colors are carried to the surface of the matrix films by sheet-like thin elements. This permits to reduce to a minimum the margin on each matrix because the necessary separation to insert said dyeing elements is very small and so the soldered matrices having less play are still more accurately registered.

One of the dyeing methods of my invention that I use consists in separately applying in succession to the matrix films the dry and the liquid components of a dyeing liquor. I first take two out pieces of a sheet like medium, tissue, porous paper or equivalents which have been impregnated with complementary dyeing solutions in concentrated form and which contain in dry state the corresponding dyestuffs and dyeing assistfilm respectively the dry colored sheets. Then I take a lintless blotter, or better a waterproof support double coated with thin, lintless blotter or equivalents, and imbibe this element in the liquid component of the dyeing liquor which is a weak solution of glacial acetic acid or equivalent, and I insert the liquid holding element between the sheets already in contact .with the matrix films.

In that manner, and by gently squeegeeing I pro-..

duce in a simple way the dyeing liquor at the very surface of the matrix films and then allow the necessary time .for their selective inking.

Another means that I may use for inking the bound matrix films and which is particularly suitable for wash-off reliefs is the polychromatic pad of my invention. Such pad consists of a thin waterproof support carrying on each side gelatine or equivalent medium in which a different coloring substance in dry state is respecti ely incorporated. Although this pad is of different types and may supply more than two colors, the one described serves the purpose for the present disclosure. For wash-off matrix films the dyeing pad may be made by double coating the support with hard gelatine amounting to 0.25 gramme per cm. and 0.03 to 0.05 gramme of selected acid dyes for the same surface. The pad, being in dry condition, needs to be soaked for about 5 minutes in water to produce the dyeing liquor in the gelatine. For that purpose a weak solution of glacial acetic acid is satisfactory, where the selected colors do not bleed. For the inking the soldered matrices are wetted in a weak solution of ammonia to produce an alkalinity which increases the affinity for acid dyes as it is well known in the tinctorial industry. The sandwich is then made, squeegeed and kept for a few minutes until the matrix films are inked.

Besides those described other means may be used for selectively dyeing the soldered matrices, although the last two are most suitable for several advantages among which their simplicity and cleanness.

After the matrices are inked, Fig. 6, the coloring element is extracted and the known mordanted double coated blank Fig. '7, previously soaked in water is introduced between the matrices, squeegeed to contact and left for a few minutes. Then the finished picture is extracted and dried.

The simplification in outfit and manipulation attained by the invention in the. described example may be now summarized:

Two wash-off soldered matrices One coloring pad One printing blank Weak glacial acetic acid solution Weak ammonia solution A squeegee Process washed in ammoniacal water for a new pass. Before flling the bound matrices for future. use it is advisable to leave them open for a few minutes; until dry and so theywill keepprotected, inregister and ready for printing at any time.

In the-example presented abicolor reproduction was considered. For three and four color work the book of matrices is permanently bound the lower element in Fig. 3 has not an image but 3 a'raticn between the attached matrix'films for providing the same with transferable coloring gas shown in Figs. 3 and 4. It can be observed that l0- represents a plain piece of Celluloid to protect the odd matrix film. As'tothe coloring, two pads are necessary, each inking two matrices or the odd one; and in regard to the printing two blanks will be used, soldered as a' book of matrices and then interleaved between the'inked matrix films.

The useof bound matrixiilms is not only applicable to the wash-oi process but to other methods involving the inking and printing of key images, with the 'obvious variation of dyeing liquors and coloring technique. 7 Y

The book of matrices is not only useful for color photography but also for combining photographic tone values' for dichroiceiiects. It may also be used with adavantage for simultaneous matrices in register substances andfor interleaving between said matrix films a blank surfaces. I
