Germany February 9, 1932 tending right to the forme surface units, of the forme to be employed for the composition for the forme surface image, and at the same time to relieve as far as possible the forme surface unit carriers of the fitting means, which, according to the rules of typographs1 pertain to an accurate assembling of the parts of the forme surface. It proposes to take up step-by-step the stepwise projections of the individual forme surface units, which are already in themselves ready for printing, on a pattern or preliminary image, introduced into the exposure position of the lightsensitive forme surface carrier and illuminated by the projection light, and to adapt the adjustments of the individual forme surface units at their taking position to this pattern, before photographing the particular forme surface unit on to the forme surface carrier in question.

By ready for printing" is to be understood in this specification, already ready for reproduction, that is to say, ready for duplication according to the rules of typography, By forme surface units are to be understood not only makingup units but also elements of making-up units (though not ordinarily such small elements as single letters), and in general all those patterns which admit of being reproduced upon the lightsensitive forme surface carrier by photographic means. vThe forme surface units themselves, the lines for example, may be set photographically or produced in any other desired manner. They are most advantageously translucent photographic images consisting of nlm or the like. The forme surface units ready for printing therefore need no further treatment beyond the mere photographic incorporation thereof in the forme surface image.

Beyond the usual sharp focusing of photographic projections by the aid of the focusing screen, the present invention comprises first the employment in conjunction therewith of a pattern at the exposure point, which can there assume any desired position, and always remains sharp and correct, and then the agreement of the partial projections with the corresponding parts of the pattern, not merely as regards sharpness, but even more as regards the image, the position of the image and the order of magnitude of the type, and finally the regulating of the adjustment of the forme surface units at their photographing position according to the nature of the pattern located at the exposure point. It is therefore a question of the stepwise backward rectification,of typographically dismembered partialL projections. sembling of the forme surface The exactitude requisite for the asunits on the forme surface carrier is here to be yielded by the pattern, which may here be a draft or some other complete sketch of the forme surface image to be prepared, but if necessary may only be an outline drawing, or even another network of co-ordinates thereof. Positive patterns are intended to permitl of being very accurately supervised in the light,

falling on themin an outward direction from within, of the projection rays that necessarily bring the negatives thereof. The photographic composing process proposed is intended to restrict to a minimum the requirements as regards the equipping of the forme surface units.v 'I'he forme surface units are to be capable of beingallocated without special rules to individual loose forme surface unit carriers, and the most varied forme surface units of the most manifold sizes on type. are to admit of being introduced in any desired ordinates of the particular pattern or of the forme surface carrier, and also inthe direction of the axis of projection in relation to the objective lens employed for the projecting, in order that it may be possible to adapt the individual projections and the individual adjustments of the forme surface units to all the patterns that occur.

The apparatus illustrated in Figures 1 and 3 is substantially a photographic reproducing camera. A standard 1 carries an objective lens 2, and also a shutter 4, actuated by means of a key 3, and is connected in a light-tight manner with a front standard 5 and with a rear plate 7 projecting upwards from an underframe 6, by means of extensible bellows 8 and 9. 'Ihe standards 1 and 5 are slidable on an upper rail or bar 10 of the underframe 6, and also along a dovetail-shaped straight line guide not expressly shownl in the drawings, so that they can never yield ina vertical direction. l

The front portion of the apparatus serves as the photographing position of the forme surface units to be incorporated in the forme surface image to be prepared, but the rear portion serves as the exposure and supervision position of the sensitized forme surface carrier. The back plate 7 forms a vertical guide for a slide-piece 11, and the latter in its turn forms ahorizontalguide for a slide 12, in which there is a circular rotatable insertion 13. To the latter is fitted a frame 14, with a dark slide or holder 16 enclosing a sensi'- tized forme carrier 15, and a focusing screen 17, in theusual manner, that is to say, in such a way as to be longitudinally slidable, sothat the forme carrier 15 and the focusing screen 1'( alternate with one another in the exposure position Y. .Accordingf to Figures 1 and 3 the glass screen 17 is located in the exposure position Y, and Figure 2 shows how the sensitized forme carrier 15, pushed into the exposure position Y, is uncovered for exposure by pulling out the cover 18 of the dark slide. 'Ihe sliding piece 11 is kept in a position of equilibrium by a counterweight 19, which hangs from a` cord 21 passing round a roller or pulley 20. Since the insertion 13 that carries the dark slide is rotatably arranged, the exposure and inspection position of the light-sensitive forme surlface carrier 15 can be rotated in its own plane into any position in order that it may be directly adapted to an oblique forme, a sheet forme, and so forth. Figure 4 shows the focusing screen 17 in the normal position, and Figure 5N shows it rotated through an angle of 45, it being in both cases in the exposure or verifying position Y. v 'I'he front portion of the apparatus, that is to say, the photographing position of the forme surf face units.' may according to the'invention be constructed in the same manner as the rear por# tion, which has justbeen described. In Figures 1, 3 and 6, merely the standard 5 has been shown as a horizontal guide for the slide 22, in which again the frame 23 is longitudinally displaceable.- The latteris pierced lby several projection windows 2 4, 25, 26,which are exchangeable with one 'aner in any position of the formeV surface units at their photographing position X. The

projection windows

24, 25 and 26 are provided withseparateledges or the like 27 for guiding and securing the'forme surface unit carriers, which may for exaxrale be film strips. 28, so 'that 'the most vari pared', and', by merely sliding the frame 23, can be brought into the photographing position X, and adjusted there into any position required. s

forme surface unit carrierscan be prev A pencil of rays from a glowlamp 29 mounted f j on the standard 5 has been indicated in Figure 1 by dotted lines. The path of the projection vrays y is left free everywhere in the usual manner.

The process described is carried out bythe aid v of this reproduction apparatus in the following mannerzv A vdrai't or a sketch 30 (Fig. 5).of the forme surface image to be produced, lis stretched upon the glass screen 17, and aporrespondingly large forme surface carrier 15 is placed in the same .position in the dark slide 18. If the sketch 30 has been drawn upon a somewhat translucent paper, it may serve itself as a matt screen, and in this case the glass 17 may be transparent. Should thesketch 30 be drawn on ordinary white paper, it vmay be made translucent by coating it with oil. In either case the sketch may be stuck to the glass plate 17 with transparent varnish or the like. The text portions of the draft will be set up in successive forme surface units line by line for instance, photographically or otherwise, the

corresponding projection window

24 or 25 will be brought into the photographic position X, the shutter 4 will be so far screened that only the adjusted forme surface unit will be projected, and the partial projection in question will be received and examined at the corresponding part in the photographing position X until the. pro-f jection of the adjusted forme surface unit agrees with the corresponding position of the draft 30. If necessary the latter may also be pushed to and fro or rotated in the exposure and inspection position Y.

The magnitude of projection is adjusted during this operation, preferably by meansy of a device which automatically preserves the sharpness of the image at every projection ratio. Such a device is indicated by way of example in Fig. 3 in the following'mahiner. The two longitudinally displaceable standards 1 andl 5 are pivoted by means of guiding
