PROVISIONAL SPECIFICATION.
An Improved Method of Producing Printed Maps, Charts, and
the like.
We, GEORGE WASHINGTON BACON, of 127 Strand, in the County of Middlesex,
Geographical Publisher, and THOMAS BEST, of 33 Hercules Road, Lambeth, in
the County of Surrey, Clerk, do hereby declare the nature of this invention to be
as follows:-
This invention relates to an improved method of producing coloured printed maps,
charts and the like whereby such articles can be produced with fewer printings and
consequently at less cost than heretofore..
By our invention we produce printed maps, charts and the like wherein the
oceans, seas and lakes are not tinted or coloured by a special printing as heretofore
but are indicated in the desired colour without such special printing.
For this purpose we print the maps ou coloured or tinted paper, blue by
preference, such paper being used just as it is delivered by the manufacturer.
What is known in the trade as the outline and the frame and names of the map are
printed in solid black or other colour, and the land and margin of the sheet are then
printed in a third colour, or two or more colours as desired; or, according to a
modification of our invention the land and margins are printed at the same time as
the outline, names and frame and in the same colour. The land and margins in
such case will not however be printed solid but will be indicated by a lighter shade
or tint, produced by using a ruled or lined surface or a stipple in a manner well
known to the trade. The colour printings have the effect of obliterating the
original colour of the paper at those places where the colour is applied thus
leaving the original colour of the paper to represent the water only. It is necessary
to print the margins as above indicated otherwise the proper effect of water will
not be secured.
It will be seen that by our improved method we can produce by one printing a
map or chart or the like having the water represented in blue, the outline and frame
in solid black or some other colour, and the land and margins in a lighter shade of
such colour; or by two printings we can indicate the water in blue, the outline
and frame in black or some other colour, and the land and margins in a third colour.
And by more printings we can produce a correspondingly greater variety of effects,
but in all cases we produce, with one printing less than has been heretofore possible,
a map having the same distinctions as coloured maps heretofore made.
In cases where we use two or more printings, the margins may be usefully
coloured a distinctive combination tint produced by blending the colours of the
separate printings.
Although we have hereinabove described the water as being represented by the
original colour of the paper it is obvious that we might represent the land by this
method, the paper being of a suitable colour, and the water being coloured by
printing in the manner above described with reference to the land.

We, GEORGE WASHINGTON BACON, of 127 Strand, in the County of Middlesex,
Geographical Publisher, and THOMAS BEST, of 33 Hercules Road, Lambeth, in
the County of Surrey, Clerk, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to an improved method of producing colour-printed maps,
charts and the like whereby such articles can be made with fewer printings and
consequently at less cost than heretofore.
The oceans, seas and lakes of maps, charts, and the like produced according to
our invention are not tinted or coloured by a special or separate printing as hereto-
fore but are indicated in the desired colour without such special printing.
According to our invention we print the maps or charts on coloured or tinted
paper, cardboard or other suitable material, blue by preference, such paper or
material being used just as it is delivered by the manufacturer. The outline of the
map, also the frame and names are printed in solid black or other colour, and the
land and margins of the sheet are then printed in a third colour, or two or more.
colours, as desired; or, according to a modification of our invention the land and
margins are printed at the same time as the outline, names and frame and in the
same colour. The land and margins in such case will not however be printed solid
but will be indicated by a lighter shade or tint, produced by using a ruled' or lined
or a stippled surface in a manner well-known to the trade. The colour printings
have the effect of obliterating the original colour of the paper at those places where
the colour is applied thus leaving the original colour of the paper to represent the
water only. It is necessary to print the margins as above indicated otherwise the
proper effect of water will not be secured.
It will be seen that by our improved method we can produce by one printing a
map or chart or the like having the water represented in blue, the outline and
frame in solid black or some other colour, and the land and, margins in a lighter
shade of such colour; or by two printings we can indicate the water in blue,
the outline and frame in black or some other colour, and the land' and margins in
a third colour. And by me
7.more printings we can produce a correspondingly greater
variety of effects, but in all cases we produce, with one printing less than has Been
heretofore possible, a map having the same distinctions as coloured maps heretofore
made..
In cases where we use two or more printings, the margins may be usefully
coloured a distinctive combination tint produced by blending the colours of the
separate printings.
Although we have hereinabove described the water as being represented by the
original colour of the paper it is obvious that by choosing a suitably coloured paper
we might represent the land by this method, the water being then indicated by a
separate colour printing in the manner herein before described' with reference to
the land.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. Producing colour-printed maps, charts or the like by a method which consists
in printing on coloured paper or other material in such a manner that the colour of
the paper or material is utilized for representing the land or the water nalour

page_text: being applied to the margins of the sheet to ensure the proper effect, substantially
as described.
2. The several modes or modifications of producing colour-printed maps, charts
or the like, substantially as herein described and for the purpose specified.
3. A colour-printed map, chart or the like produced by any of the methods
herein described.
