The present invention relates to a process for making a two sided, multiple print static cling sign for a window and the resulting product.
Static cling signs are utilized in many applications but particularly are utilized in automobiles. The static cling sign generally includes a plastic substrate which, when placed against a glass window, removably attaches to the glass via a static cling characteristic established between the plastic and the window.
A problem has arisen in creating these static cling signs in that it is sometimes difficult to provide multiple colors on the static cling signs and to provide signage on both the front side, which is typically removably attached to the window, and the rear side, which is visible to the occupants of the building or automobile.
It is an object of the present invention to provide a process for making a static cling sign wherein the sign is made with multiple prints.
It is another object of the present invention to provide a static cling sign with a border which reduces the required precision to register the predetermined print patterns on the front side and the rear side of the static cling substrate.
It is another object of the present invention to provide a static cling sign wherein the border delimits the sign periphery and a plurality of signs can be printed simultaneously on a single large substrate sheet and then the signs can be cut from that single large sheet based on cutting within the peripheral borders.
The process for making a two sided, multiple print static cling sign includes providing a sheet like substrate of static cling material. One side is printed with a first color in a predetermined pattern and then is printed with a second color in a predetermined pattern. These predetermined patterns may or may not have void or open spaces. A border is printed delimiting the print on one side. Third and fourth colors are printed on the other side and each color has a predetermined pattern. A border is also printed on the other side delimiting the sign. The substrate is cut within the peripheral borders and a protective cover is removably attached to one of the side of the printed substrate.
Further objects and advantages can be found in the detailed description of the preferred embodiments when taken in conjunction with the accompanying drawings in which:
The present invention relates to a process for making a two sided, multiple print static cling sign and a sign made in accordance with the process.
Returning to
Since the static cling sign is printed on both sides, persons on either side of the window can see the sign. Further, since the base color is printed on both sides, there is substantially no visual interference between the printed sign on side A as compared with the printed sign on sign B. The substrate defines a two sided sign.
In one embodiment, a white base color was printed on side A and then a red primary coverage color was printed on side A over the white base cover. The voids in the primary red color on side A appear as “white print” since the white base cover color is presented to the user viewing side A. The base color utilized on side B was yellow. The base color on side B had a void or an open space in the color. Since the combination of red and white on side A results in a pink color, this pink color was visible on side B through the void in the yellow color base. If the first base pattern on side A has a void which is in registration with the void 21 in the base color of pattern 4 on side B and is also in registration with void 23 in the primary blue color of pattern 5 on side B (
The variable registration or the maximum variable registration Vm is based upon the size of the border field BF.
It should be noted that the printing of the static cling signs could be done in different stages rather than sequentially on a single side. Also, a plurality of signs could be printed on a single sheet and the sheet can be cut. Alternatively, the static cling sheet could be cut and then the base or border could be printed around the peripheral edge of the cut static cling sign. Thereafter, the colors and patterns 1, 2, 4 and 5 could be printed onto the static cling sign. Preferably, silk screen printing is utilized. More than two colors may be printed on each side.
