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
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." (John Swain Son Ltd.)

CANNING AND PACKING Mr. Charlton knows his subject intimately and the points he covers include the
essentials of the package, types of package, construction, materials, old and new packages, equipment, when to change
the package, and last, but not least, the future of the packages. The illustrations are some of the best examples
