The Art of Packaging By D. E. A. CHARLTON THE STUDIO LIMITED, 44 LEICESTER SQUARE, LONDON, W.C.2 of any of them. The three methods are as follows 1. Direct from the colour positive original by means of the usual transparency holder frame supplied with the normal process camera, always presupposing that such a camera equipment will allow of the required degree of enlargement. The colour separated screen negatives are then obtained in the normal manner, using filters Wratten No. 29 Red, No. 61 Green, and No. 49 Blue. 2. The original is placed in the type of precision enlarger used for miniature camera work and by this means of pro jection, colour separations are obtained by using suitable filters and sensitised material in place of the usual papers. From these separations the normal screen negatives are made, and if necessary, still further enlarged by means of the transparency holder on the process camera. 3. Using a projector to project the coloured image upon a screen of the finest ground glass, the projected image is then photographed in the usual manner from the opposite side from the projection. When using this method it is advisable to project the image larger than the size required, so that actually there is a reduction. Finally, the most satisfactory filtersWratten No. 29 Red, No. 61 Green, and No. 49 Blue. For continuous tone separations, Super-Sensitive Panchromatic film is suitable, although for direct screen separation, naturally a slow-working process, panchromatic plate or film would be used. Very fine letterpress reproductions are now being made by these methods and a new field has thus been opened for the user of colour illustration." There has been a marked advance in the quality of studio photography. The artistic possibilities of photo graphy by means of improved lighting and apparatus are being taken full advantage of and the results, showing increased artistic values, are very noticeable. Colour Photography has also developed considerably and for the purposes of advertising, several methods have been per fected, such as Dufaycolor, Kodachrome, Vivex and Agfa. The development of Offset Litho has made remarkable progress, the introduction of a method of making the plates known as Offset-Deep having contributed largely to the commercial practicability of the process. In rotary Gravure there is no outstanding development. Half-tone and Line blocks continue in great demand as the most useful of all methods of illustration for the letterpress printer, but in meeting the special need for water colour effects on non-surfaced papers, Offset Litho has found a very definite place for itself and the demand for it is in creasing rapidly."
