Abstract

A coloured transparency is produced by printing upon cellulose acetate film of a type which is glossy on one side and initially matt on the other side, the printing being done in coloured inks by letterpress printing or offset lithograph printing on the initially matt side in reverse, for viewing through the glossy side, the inks being plastic laminate foil inks in four colours. The transparency may be embedded in an acrylic block, or laminated in transparent polyester or polyvinyl chloride or assembled in a frame of transparent acrylic, by way of example. <IMAGE>

Description

SPECIFICATION Transparencies This invention relates to transparencies.
Known transparencies are mostly produced photographically upon reversible photographic film, whether such transparencies be original photographs or copies of photographs, and it is a fact that such known transparencies are expensive to produce.
According to the invention, there is provided a coloured transparency produced by printing upon cellulose acetate film, wherein the film is glossy on one side and has an initially matt finish on the other side, the printing being done in coloured inks upon said other side in reverse for viewing through the glossy side, and wherein the inks are plastic laminate foil inks.
Preferably the inks are in four colours to British Standard No. 41/60, such as those of Coates Inks Limited.
Preferably the printing has been done by letterpress or offset lithograph.
It is possible by means of the invention to produce postcard-size transparencies in considerable numbers for only a cost of pennies per transparency, an order of magnitude cheaper than the known photographic transparencies.
Transparencies in accordance with the invention may be utilized in various ways.
One way is to embed the transparency in an acrylic block, made by taking two or more thicknesses of acrylic, sandwiching a transparency in accordance with the invention between the acrylic thicknesses and sealing the transparency therein by the use of initially liquid acrylic, in an adaptation of the wellknown method of embedding or encapsulating articles in acrylic material, after which the block should preferably be polished on all surfaces so as to give the appearance of being homogenous.
Another possibility is to laminate a transparency in accordance with the invention in two or more layers of transparent polyester or polyvinylchloride.
A third possibility is to provide an assembly of a frame of transparent acrylic and a transparency in accordance with the invention, arranging the transparency so that it can be viewed through a panel of the frame and through the glossy side of the transparency.
A laminate as described above may be incorporated in a Greetings card or a bookmark, with a cord or the like attached to the laminate in the latter case.
However, there may be very many other applications of the invention.
The advantage of letterpress printing over offset lithograph printing is that a better quality print is obtained by letterpress printing, due to a greater charge of ink being applied to the film in letterpress printing.
In the printing process, it is advisable for each piece of the cellulose acetate film to have a piece of tissue backing paper attached to one edge of the film on its glossy side, leaving the matt side exposed for printing, in order to avoid two or more films becoming stuck together due for example to electrostatic charge. The tissue backing sheet can be removed after printing has been completed.
Greetings cards may be made by enclosing transparencies in accordance with the invention in covers of paper of 100 grams per square metre quality.
The cellulose acetate film may be that supplied by G.W. Film Sales as .075 millimetre matt polished acetate.
1. A coloured transparency produced by printing upon cellulose acetate film, wherein the film is glossy on one side and has an initially matt finish on the other side, the printing being done in coloured inks upon said other side in reverse for viewing through the glossy side, and wherein the inks are plastic laminate foil inks.
2. A coloured transparency as claimed in claim 1 wherein the inks are in four colours to British Standard No 41/60.
3. A coloured transparency as claimed in claim 1 or 2 wherein the printing has been done by letterpress or offset lithograph.
4. An acrylic block comprising a transparency as claimed in claim 1, 2 or 3 embedded within the block.
5. A laminate of a transparency as claimed in claim 1, 2 or 3 in two or more layers of transparent polyester or polyvinyl chloride.
6. An assembly of a frame of transparent acrylic and a transparency as claimed in claim 1, 2 or 3, the transparency being viewable through the glossy side through a panel of the frame.
