PRINTED DISPLAY SIGN

Abstract: A printed display sign particularly for use with a light box reversed printed on its rear face with information, typically a menu for a fast food outlet. The information includes product names and aligned with each product name is a rectangular transparent window area where the sign is not printed. The rear of the sign is painted with a white diffusing layer which covers the entire rear surface of the sign apart from the windows and the areas bordering the windows which are not coated with the diffusing layer so as to leave a rectangular dark border or frame around each window. Labels having a size larger than that of the window but preferably smaller than that of the outer edge of the border can then be located essentially within the window using the outer edge of the border as a guide. The front of the label is printed with price indicia and if the label is correctly applied to the window, which can be checked by reference to the border, the price indicia should align correctly with the product name indicia. Thus the invention provides a method of ensuring that a printed display being made with adjustable prices but which includes a system to ensure that the labels displaying each price is correctly aligned with its related product name so that the appearance of the sign from the front is professional.

Description: PRINTED DISPLAY SIGN Field of the Invention This invention relates to a printed display sign. In particular it relates to a printed sign for displaying information such as the types of products for sale and their prices in an establishment such as a fast food outlet. The sign may be backlit by a light box. Background of the Invention Fast food outlets often provide a display sign comprising a menu of the products available and photographs of those products behind the counter of the outlet at approximately head height. The signs are often backlit using a light box to create an illuminated display. In one existing display system, the front of the display comprises an acrylic panel which defines a series of pairs of rails or the like into which printed display panels can be inserted. The panels indicate the name of a product such as "cheeseburger". The price of that product is also printed on a panel and is also inserted between the rails aligned with the name of the product. If the price changes, the panel which displays the price can be removed and replaced with a new panel showing the new price. In some more sophisticated display systems, individual figures on the pricing panel can be removed and replaced. Thus, for example, a price of $2.30 could be amended to read $2.35 by simply removing the end "0" and replacing it with a "5". There are two problems with the existing display system described above. First, it is quite complex, compared with just printing a menu and is consequently expensive. Secondly, the arrangement of rails and panels is relatively bulky and occupies much of the surface area of the light box display leaving less space for the display of photographs of the products available at the outlet. This is generally undesirable as often the product photographs "sell the product" more than the printed menu and generally the more photographs displayed, the better the product sales are at a particular outlet. Also, since the display is modular, its appearance is not as uniform and smart as a simple printed panel displaying the same information would be. Ideally, the display should be as professional looking as possible with all the names and prices horizontally and vertically aligned in correct registration to give a good impression to customers. A scruffy menu display might give customers the impression that the outlet's standards, including perhaps its hygiene standards, were low. If instead of having a display where the prices and names of products can be changed, a printed sheet displaying all the current menu information is used, the lettering takes up less surface area than the rails and panels. The same information can be displayed on a smaller surface area and the menu display can be smaller, allowing more pictures to be displayed on the light box. Justification of the product names, and horizontal and vertical alignment of the product names and prices can be more accurately controlled. The overall appearance is also more professional and smarter than having removable prices. The printed sheet menu display can be backlit more effectively by the light box. However, the problem with such a printed menu is that if the price of any of the products is to be changed, whether permanently, or in the case of a special promotion temporarily, the entire display sign has to be reprinted. It is an object of the present invention to alleviate the disadvantages of the prior art discussed above and provide an improved printed display sign. Summary of the Invention According to the present invention, there is provided a printed display sign including a sheet of transparent material defining a front face which displays printed information and a rear face, wherein information visible from the front face is printed on the rear face of the sign to be read from the front face, the information including at least a first indicia such as a product name or the like and at least one transparent window area aligned in registration with that first indicia, wherein a frame extends around the window areas on the rear face of the sign, the frame being non-visible from the front of the sign and whereby a removable label having an adhesive front face, displaying second indicia, such as price indicia or the like on said adhesive front face, and being of a size larger than that of the window, may be applied to cover the window area by using the frame as a guide, so that the second indicia is aligned in correct registration with the second indicia. Typically the printed display will be a menu for a "fast food" outlet and the product names will be food items. When the inventor originally attempted to design a printed display menu with transparent windows, behind which removable price tags could be located to enable the prices of the various products to be changed without throwing away the entire sign, the inventor discovered that when the prices were stuck on the rear face of the sign, it was impossible to ensure that the prices were correctly aligned. Viewed from the front, the printing looked uneven and the display sign was commercially unacceptable. After trying out a number of systems, the inventor discovered that the provision of a frame around the outside of the window provides a guide on the rear of the sign which can be used to ensure that each price is correctly aligned with its related product name so that the appearance of the sign from the front is satisfactory. Typically, the sign will be screen printed with headings such as "breakfast" or "beverages" printed on the rear of the transparent medium first, followed by a dark coloured background such as black or brown, leaving blank spaces defining the windows and the lettering for the products such as "cheese burger" or the like. Following that stage, a coat of white paint is applied to the rear of the screen over the previously applied paint. This white layer acts as a diffuser when the sign is placed in front of a light box and makes the display less harsh on the eye than if the transparent areas defining the lettering were left clear. The white paint is applied in such a way that it does not extend as far as the edges of the window but leaves a dark border or perimeter around the window. This border defines the frame for the window. Ideally, the windows and the adhesive labels displaying prices will be rectangular. The labels will typically be made from vinyl and are coated with a low tack adhesive so that they can be easily removed from the display sign for replacement. In a particularly preferred embodiment, as well as including windows for prices, the sign also includes elongate windows for product name indicia and further windows for prices. Normally those windows will be blanked out with plain labels the same colour as the dark background. However, it is possible to add new product lines or "specials" to the sign, if desired, by removing the plain dark labels from the windows and replacing them with appropriate labels displaying the new product information. The display sign is typically used with a lightbox thus the invention also provides a light box and printed display sign assembly comprising in combination:- a) a lightbox; b) a printed display sign positioned so as to be backlit by the light box. said printed display sign comprising a sheet of transparent material defining a front face and a rear face, information being reverse printed on the rear face of the sign so as to be readable from the front face, the information including a series of first indicia such as product names printed in at least a first colour, the sign being printed with a second background colour, different from the first colour, defining a series of transparent windows defining an area, aligned with at least some of those product names, the rear face of the sign being coated with a diffuser layer which defines a frame around each window: and c) removable labels larger in size than the area of the windows displaying second indicia, typically price indicia, reverse printed on a front face of each label, the labels being applied to the rear of the sign covering the window areas, the frames enabling correct location of a said label in a said window such that the that the second indicia are aligned in correct registration with the first indicia to which the second indicia relates. The present invention thus provides a low cost and flexible system that can provide professional looking signage at a much reduced cost from the adjustable signage currently available. The quality attainable is such that from the front it appears as if the entire sign has been screen printed. The provision of the frame by the rear light diffusing layer means that the actual cost of producing a frame around the window for location of the price indicia does not add to the manufacturing process since the provision of the diffusing layer is a required step in the process for making the sign. Brief Description of the Drawings A specific embodiment of the present will now be described, by way of example only, and with reference to the accompanying drawings in which: Figure 1 is a front view of part of a printed display sign embodying the present invention; Figure 2 is a rear view of the part of the sign shown in Figure 1; Figures 3a to 3h illustrate the steps involved in changing a price on a printed display sign embodying the present invention; and Figure 4 is a schematic perspective view of a light box incorporating a display sign. Detailed Description of a Preferred Embodiment Referring to the drawings, a sign 10 has a front face 10 A as shown in Figure 1 and a rear face 10B shown in Figure 2. The sign comprises a sheet of polycarbonate which is printed on its reverse side. Reverse side printing protects the printing from damage by contact with the front face of the sign. The front face of the sign may be coated with a protective layer. The polycarbonate is typically about a half a mil thick although other thicknesses could be used. Turning to Figure 1, the front of the sign shows a heading "Breakfast Mc Value Meals" 12 which is set against a rectangular background area 14. Although the particular colours used are not critical, the lettering is blue and the background is yellow since that particular colour combination tends to attract the eye of a customer and can be easily seen. Generally speaking, the blue lettering 12 is first printed on the reverse side of the polycarbonate sheet and then the yellow background 14 is printed, subsequently, although printing the yellow first is possible. Typically, the display is screen printed using epoxy inks. After the blue and yellow areas 12 and 14 have been printed, the dark background 16 is then printed. The area covered by the background 16 is the entire rear surface of the sign but excluding the following :- i) the already printed areas 12, 14; ii) areas which are left unprinted and transparent and which when read from the front provide general menu information 18 such as "includes Hash Brown and Regular Coffee"; and iii) areas which are left unprinted and transparent and which when read from the front provide product name indicia corresponding to a product, for example "Bacon and Egg McMuffin™" 20; and iv) aligned in registration with each product name indicia, a rectangular transparent window area 22. Note that, although in Figure 1, it appears that there is no rectangular window area 22 aligned with the indicia "Sausage & Egg McMuffin™", the price "3.25", as will be explained below, is on a removable label/sticker and is not printed on the display sign. If the label/sticker were removed, a rectangular window similar to window 22 would be seen. The final coating on the rear of the sign, shown in Figure 2 is a layer of white epoxy paint which acts as a diffuser. This layer coats the entire rear surface of the sign apart from a series of rectangular areas 24, of slightly greater size than the transparent windows 22. The layer of white paint acts as a diffuser and makes the sign less harsh to view, when the sign is placed in front of a light box. As can be seen the light diffusing layer is printed such that it leaves a rectangular boundary or frame 24 around the window 22. A similar boundary 24A can be seen around the window associated with the "Sausage & Egg McMuffin™" indicia. Note that, because the diffuser layer is white and thin it is possible to discern the previously printed darker layers of paint and lettering through the diffuser layer when viewing the rear of the sign. The labels displaying the price information 26, are made of vinyl and the front of the labels which is stuck against the window is coated with a low tack adhesive so that the labels can be easily peeled off. The use of a frame around the window enables every label to be correctly aligned and justified with the other prices in the display. For best results, each label should ideally be stuck in an identical fashion to the other labels, for example each label 26 may be stuck flush with the upper surface of the windows 22 so that a thin uniform black line can be seen between the rear surface of the label 26 and the diffusing layer. Each label 26 is also preferably coated with a layer of white paint as a diffuser. When the price has to be changed, the label is simply peeled off and replaced with a new label. The labels should be larger than the windows 22 but are preferably slightly smaller than the frame perimeter so that they fit inside the frame perimeter leaving a dark rectangular perimeter around the label. It is also possible using the principle of the present invention to provide elongate rectangular windows (not shown) which would normally be covered with a plain black label matching the dark background of the sign but which can be peeled off to enable an extra product name to be added to the list of products available. A corresponding aligned window is also provided for the price of that product. Figures 3a to 3h, illustrate a step by step process for changing the price of one of the menu items. In the first step illustrated in Figure 3a, the sign 10 is placed face down on a clean flat surface with the rear 10B of the sign facing upwards. Figure 3b is an enlarged view of a corner of the sign and a restaurant worker observing the rear of the sign will notice a white background with certain areas having attached stickers or labels 26 already in place. Turning to Figure 3c, the worker then has to determine which label or labels are to be changed, say sticker 26A. With reference to Figure 3d, the worker 40 then simply peels off the label 26 A which it is desired to remove. The front face of the label is the colour of the background of the sign, aside from the numbering appearing on the label. Next the worker takes a replacement label 42. In order to protect the label a white paper cover 46 protects the sticky front face of the label and a clear plastic cover 44 protects the rear of the label. The clear plastic cover 44 also helps prevent the label 42 deforming or stretching when it is applied to the rear of the display sign. After selecting a label displaying the correct price, the paper cover 46 is removed as shown in Figure 3e and the label is carefully placed in the middle of the exposed frame on the rear of the sign using the frame defined by the white border of the diffuser layer as a guide. Typically, thin dark rectangle would be defined around between the label and the edge of the diffuser layer which will indicate to the operator that the label is evenly applied. Finally as illustrated in Figures 3g and 3h, the label is rubbed to ensure that there are no air bubbles trapped between the label and the rear of the display sign and the clear plastic cover 44 is peeled off. The operation is repeated for any other labels/stickers which have to be changed and the sign is then replaced in the light box. Figure 4 is a view of a lightbox 100 illuminating a printed display sign 110 embodying the present invention. Thus the present invention provides a system in which a sign which appears to be entirely screen printed, such is the quality of the justification/registration which is possible, can in fact be simply and cheaply amended to alter the prices of the product, and the product name. Although the above description refers to the use of the signage of the menu for fast food outlets and particularly with lightboxes, the sign could also be used with printed display signs displaying other information which may need to be altered over time. It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
