Abstract
A coated substrate comprises a substrate 13, in the form of a layer of varnish or lacquer applied to a carton blank 11, the substrate having a material 15, which may also be a varnish or lacquer, coated thereon. The substrate 13 has a high coefficient of slip with respect to the material 15 and may include a high proportion of silicon slip additives. The material 15 is deposited as a liquid which is rejected by the high slip coefficient substrate 13 and retreats therefrom and may form a droplet pattern. The material 15 is then solidified and is arranged to be retained on the substrate 13. <IMAGE>
Description
A TEXTURED COATING
The invention relates to a textured coating and particularly, but not exclusively, to a coating for application to a card blank for a container.
A number of different methods are known for applying a coating to a surfaces It is common to apply two or more coatings to a surface, for example to provide different colours or to provide a glossy or protective finish. However, the composition of the coating and deposition process are usually controlled so dS to give a substantially uniform thickness,
According to one aspect of the invention there is provided a coated substrate comprising a substrate having a liquid material deposited thereon, the liquid material and the substrate being such that the liquid material is rejected by the substrate and retreats therefrom but is retained thereon when solidified.
Depending upon the amount of liquid material deposited on the substrate per unit area and the length of time the liquid material is allowed in which to rctreat from the substrate, the liquid material may form distinct droplets on the substrate or may form a layer having circular discontinuities or may form any intermediate state. If the substrate is printed in a particular pattern then clearly the material will be rejected in relation to whether substrate is present what the rejecting properties are of the particular substrate.
The material may be colourless and transparent when solidified. This provides a "water-splash" appearance which is attractive. Alternatively the material may be pigmented to provide a different effect
One method of providing for rejection of the material is to give one of the substrate and the material a high level of slip with respect to the other.
Preferably the substrate has a high coefficient of slip with respect to the material. The substrate may contain a high proportion of silicon slip additives.
The substrate may be any desired shape, such as cylindrical, spherical or irregularly shaped, but preferably the substrate is flat
The substrate may comprise a body of any desired composition and in the case where the substrate has a high level of slip with respect to the material the substrate may, for example be a suitable plastics material or a material impregnated with a substance or substances to provide a high level of slip.
Preferably, however the substrate comprises a layer applied to a surface. The surface may be of any composition and may be e.g. glass or plastics but preferably the surface is made from card or paper.
The surface preferably comprises a blank for a container. The substrate layer may be of any type and may e.g. be an ink but preferably the substrate layer is a varnish or lacquer.
Preferably the material is such that is can be solidified from the liquid form with substantially no volume change. Thus the material will not by a volume change on solidification detach itself from the substrate. The material is preferably a varnish or a lacquer. The material may bo solidified hy subjection thereof to a UV light source.
The liquid material may be deposited on the substrate as a layer of substantially constant thickncss.
Preferably the liquid material is deposited from a roller.
roller.
According to a further aspect of the invention there is provided a method of forming a coating comprising depositing a liquid material on a substrate, the liquid material and the substrate being such that the liquid material is rejected by the substrate and retreats therefrom, and solidifying the liquid material thereafter, the material and substrate being such that the material is retained on the substrate on solidification.
An embodiment of the invention will now be described by way of example and with rcference to the accompanying drawings, in which:
Fig. 1 is a schematic diagram of apparatus for forming the coating;
Fig.'s 2 and 3 are views of coatings, and
Fig. 4 is a cross-sectional view on IV - IV in Fig. 3.
Fig.'s 5 and 6 are further views of the coatings.
Fig. 1 shows printing apparatus 10. A card sheet 11 passes through a first printer 12 and a substrate 13 is deposited as a layer onto the sheet 11. The substrate layer 13 is then dried by a first dryer 18.
me sheet 11 then passes through a second printer 14 in which a liquid material 15 is deposited onto the substrate 13. The liquid material 15 and the substrate 13 are chosen such that the liquid material 15 is rejected and retreats from the substrate 13 to give an appearance as shown in Figs. 2 and 3. When the card sheet 11 comes out of the printer 14 it passes under a second dryer 16 which dries the liquid material 15 to solidify it. The card sheet 11 then passes through a cutter 17 to be cut to a desired shape e.g. to form a carton blank. In a preferred embodiment, the substrate 13 is L & B litho varnish grade U1743F, The substrate layer 13 is deposited by a lithographic process and the first dryer 18 is a UV dryer. The material 15 is coates UV roller coat varnish grade V02345 and is deposited as a roller coat by the second printcr 14.The second dryer 16 is also a UV dryer and the material solidifies by chemical change with substantially no volume change.
The card sheet is passed through the second printer 14 at a speed of about 1750 mar 1, the distance roller of the second printer 14 and the second drier 16 is about 3m and about 8 gum 2 of material 15 is deposited on the substrate 13.
Fig. 2 shows an example of a pattern of droplets which may be formed by the liquid 15 on the substrate 13,
Fig. 4 shows this in a cross-section and illustrates the manner in which the liquid and the substrate repel to provide a small contact area hence resulting in the droplet effect. This may be particularly cffective if the material is transparent when solid as it will provide an appearance in the coating of having been water splashed. The material may be coloured when solid, however, to provide a different effect. As the liquid is applied evenly to a flat surface the droplets are formed effectively at random so that no two coatings produced will be identical.
Figures 5 and 6 show different patterns which may be obtained.
In Figure 5 the material 15 has retreated from the substrate 13 to provide small areas of the substrate surface which are clear of material 15. This effect can be produced by depositing a greater amount of material 15 per unit area of substrate 13 or by reducing the amount of time allowed for the material 15 to retreat from the substrate 13 before drying.
This is generally done simply by increasing the speed at which the card sheet 11 passes through the second printer 14.
Fig. 6 shows the effect provided by adjustment of the parameters in the opposite manner. Thus, if the period allowed for thc material 15 to rctreat from the substrate 13 is increased or the amount of material 15 deposited per unit area on the substrate 13 is reduced, the material 15 forms small droplets on the substrate 13 and fewer elongate splash-type globules are formed.
The apparatus 10 need not be as shown but may take any suitable form.
The first printer 12 may be omitted if thc sheet 1 has or is provided with the appropriate qualities with respect to the material used. More than one printer 12 may be used if more than one initial printing stage is desired e.g. to allow a plurality of colours to be used. The first printer 12 need not print lithographically but may print by a gravure process or by any other suitable process. The substrate 13 need not be a varnish but may be an ink or any other suitable substance.
The coating need not be applied to a flat sheet but may be applied to a body of any desired shape e.g. a cylindrical body. The liquid material 15 need not be applied over the entire surface of the substrate 13 but may be applied over any desired portion.
The liquid material 15 need not be a varnish but may be an ink or any other suitable substance. The liquid material 15 need not be liv dryable but may be dryable in any suitable way such that the material keys with and is retained on the substrate. The second printer 14 need not be a roller printer but may B.g. be a lithographic printer or a printer of any other desired appropriate type.
Where a high level of slip is referred to, this is intended to mean a high surface tension with respect to a liquid and a low coefficient of friction with respect to a solid.
