Abstract: 905,184. Photographic type - composing. MONOTYPE CORPORATION Ltd. Sept. 28, 1960 [Sept. 28, 1959], No. 32896/59. Class 98 (1).  Means for use in the making up or correction of text or other matter recorded on film for the production of printed matter comprises a sheet with horizontal and vertical rulings to form a grid, a transferring and locating member of transparent flexible material having marked thereon horizontal and vertical scales, some of which when co-operating with the grid of the said ruled sheet provide vernier readings for accurately locating text or other matter on a transparent make-up sheet superimposed on the said ruled sheet, the underside of said transferring and locating member having adhesive properties so that the said text or other matter adheres thereto. The transparent transferring and locating member 1 (Fig. 1) bears a datum line 5, a scale 2 marked off, for example, in 6-point lengths, and various scales 3 and 4 and other datum lines 9. The transparent sheet 15 (Fig. 2) bears grid lines 16, also at 6-point spacings. A transparent make-up sheet 19 is layed on the sheet 15 and both are layed on an illuminated make-up table top 17. A membrane bearing matter to be made-up, such as is indicated at 21, is severed from a stripping film, and is secured to a self-adhesive lower surface of member 1 in such a way that the base line of the membrane 21 and the datum line 5 of the member 1 coincide and so that the membrane 21 is centred about the zero graduation of the member 1. This member 1 is then layed on the make-up sheet 19 and the position of membrane 21 accurately adjusted with the aid of said scales, datum lines and grid lines 16. The membrane 21 is then firmly pressed into adhesive contact with the sheet 19 and the member 1 removed. To enhance the separation of the membrane from the member 1, a strip of material 22 is used, the lower surface of which strip is adhesive for the membrane 21, but the upper surface of which is non-adhesive for the member 1. Alternatively a marking member 23 (Fig. 1) slidable along the member 1 may be provided. For correcting matter on a make-up sheet, the unwanted matter is first cut around, and the replacement matter is then accurately aligned by means of the member 1 above the unwanted matter. Having found the required position, one end of the member 1 is pressed into adhesive contact with the make-up sheet, the other end is bent upwards, the unwanted matter is removed, the replacement matter is returned to its original position and is firmly pressed into place as before. The member 1 preferably comprises two layers of synthetic plastic material bonded together, either both layers being of polyvinyl chloride or one being of such material and the other of polystyrene. The self-adhesive surface is obtained by polishing an exposed polyvinyl chloride surface. The make-up sheet may also consist of two layers of sheet material bonded together-one being a synthetic plastic material having selfadhesive properties.
