Definitions
- the present invention relates to an apparatus and a method for ejecting material from a liquid. More particularly, the method and apparatus employed may be generally of the type described in WO-A-93/11866, WO-A-94/18011 and WO-A- 95/32864. In the methods described in these patent applications, an agglomeration or concentration of particles is achieved at an ejection location and from the ejection location, particles are then ejected on to a substrate, e.g. for printing purposes. In the case of an array printer, plural cells each containing an ejection location may be arranged in one or more rows.
- One particular application to which the invention may be applied is the transfer of agglomerations of high intensity colouring materials to a recording surface for the purpose of non-impact printing. It is to be understood, however, that the invention is not limited to delivering coloured materials for the purpose of non-impact printing, but may be used to deposit other materials in a defined pattern on a substrate. Examples of other applications include delivery of etch resistant material, printing functional elements and deposition of phosphors or flurophosphors for security coding.
- ink jet printing There are a number of different forms of equipment used for the non-impact printing systems which are generally referred to as ink jet printing. It is usual for ink to be fed through a nozzle, the exit diameter of which is a major factor in determining the droplet size and hence the size of the resulting dots on a recording surface.
- the droplets may be produced from the nozzle either continuously, in which case the method is termed continuous printing, or they may be produced individually as required, in which case the method is termed drop on demand printing.
- continuous printing an ink is delivered with the nozzle at high pressure and the nozzle is perturbed at a substantially constant frequency which results in a stream of droplets of constant size.
- Drop on demand printing operates by producing local pressure pulses in the liquid in the vicinity of a small nozzle which results in a droplet of liquid being ejected from the nozzle.
- the colouring material is typically a soluble dye combined with binders to render the printed image more permanent.
- the disadvantages of soluble dyes is that the printed image density is not high enough in many applications and that the dyes fade underexposure in the environment.
- a further disadvantage with soluble dye materials is that the quality of the printed image is dependent upon the properties of the recording surface.
- Pigment inks are known to produce higher density images than soluble dyes and are also more permanent. Pigments may also be used in jet printers but the production of a dense image requires a high concentration of pigment material in a liquid carrier. The high concentration of pigment material effects the droplet break up in continuous printers and results in less uniform printing. Drop on demand printers do not have a high continuous pressure and the droplet generation is strongly dependent on local conditions in the nozzle, therefore the presence of pigments can block the nozzle or otherwise modify the local nozzle conditions such that droplets are not correctly ejected.
- a further disadvantage of the above types of jet printing is that the printing is carried out in a substantially vertical plane on to a substantially horizontal surface. This is because the liquids that are typically ejected have a relatively low viscosity and therefore it is not possible to print on a non-absorbing surface that is anything other than substantially horizontal because the liquid being deposited would drip down the surface, therefore effecting the quality of the printing.
- a non-absorbing substrate such as glass, metal or plastic it is necessary for the substrate to be surface treated prior to the application of the material to be deposited.
- a method of applying markings to a non-absorbent, substantially vertically arranged surface comprising generating discrete agglomerations of a particulate material with a proportion of liquid from a liquid having the particulate material therein, the method further comprising the steps of providing the liquid including the particulate material to an ejection location by applying an electric potential directly to the ejection location to form an electric field at the location, to cause agglomerations to form at the ejection location and to eject the agglomerations out of the liquid and away from the ejection location substantially horizontally by electrostatic repulsion between the agglomerations and the ejection location and on to the surface. Since the surface on which the particulate material and liquid is to be deposited is substantially vertical, it is also possible to deposit material on both sides of the surface at the same time, thereby reducing the material
- both sides can be printed and dried at the same time, thereby reducing the time required for and the complexity of the printing process.
- the electrical potential forming the field may be pulsed so that there is periodic formation and ejection of agglomerations of particles in the liquid from the ejection location.
- the method of the present invention may be utilised to print on to a glass surface for applying decoration and patterns or, alternatively, for printing functional elements such as electrical circuits.
- the invention could also be utilised for printing on to a metal surface using an oleophilic or oleophobic material to create a pattern that can be used as a printing plate.
- the invention can be used to print a etch resistant material on to a surface, thereby generating a pattern that can subsequently be etched into the surface. It may also be possible to move the ejection location across a large vertical non-absorbing surface, such as architectural glass, to create patterns on that glass.
- the invention also includes an apparatus for applying markings to a non- absorbent, substantially vertically arranged surface by the generation and ejection by electrostatic repulsion into air of discrete agglomerations of a particulate material with a proportion of a liquid from a liquid having the particulate material therein, the apparatus comprising an ejection location and liquid supply means to supply liquid with the particulate material to the ejection location, and electrical potential application means to apply an electrical potential directly to the ejection location to form an electric field at the location to eject the agglomerations out of the liquid and away from the ejection location substantially horizontally.
- the apparatus also includes means for supporting a workpiece such that the surface on which the agglomerations are to be ejected is substantially vertical.
- means to provide a flow of liquid to and from the ejection location Such a flow may be provided by means of a pump or by gravity feed or some other means.
- the apparatus according to this invention may be adapted to provide agglomerations on demand or to provide a continuous stream of agglomerations which can be deflected by electrostatic means external to the apparatus.
- the supply of agglomerations of particulate material on demand may be provided by providing a pulsed electrical potential to the ejection location.
- the apparatus may include a mechanism which enables the ejection locations to be moved in one, two or three dimensions such that the ejected material can be deposited on a large surface.
- Figure 1 is a partial perspective view of a portion of a first print head incorporating ejection apparatus according to the present invention.
- Figure 2 is a schematic perspective view of part of a printing apparatus in which the present invention can be used.
- Figure 1 illustrates part of an array-type print head 1 , the print head comprising a body 2 of a dielectric material such as a synthetic plastics material or a ceramic.
- a dielectric material such as a synthetic plastics material or a ceramic.
- a series of grooves 3 are machined in the body 2, leaving interposing plate like lands 4.
- the grooves 3 are each provided with an ink inlet and an ink outlet (not shown, but indicated by arrows I and O (deposed at opposite ends of the grooves 3 so that fluid ink carrying a material which is to be ejected, as described in our earlier applications, can be passed into the grooves and depleted fluid passed out).
- Each pair of adjacent grooves 3 define a cell 5, the plate like land or separator
- each separator 7 formed by one of the plate like lands 4 and the corner of each separator 7 is shaped or chamferred as shown so as ' to provide a surface 8 to allow the ejection up stand 6 to project outwardly of the cell beyond the exterior of the cell as defined by the chamferred surfaces 8.
- the truncated up stand 6' is used in the right hand, end cell 5 of the array (and similarly in the end cell at the other end - not shown) to reduce end effects resulting from the electric fields which in turn result from voltages applied to ejection electrodes 9, provided as metalised surfaces on the faces of the plate like lands 4 facing the up stands 6, 6' (i.e. the inner faces of each cell separator).
- the truncated up stand 6' acts to pin the liquid meniscus which in turn reduces end effects during operation, which might otherwise distort the ejection from the adjacent cell.
- the electrode 9 in the end cell is held at a suitable bias voltage which may be the same as a bias voltage applied to the ejection electrodes 9 in the operative cells as described in our earlier applications mentioned above.
- the ejection electrode 9 extend over the side faces of the lands 4 and the bottom surfaces 10 of the grooves 3. The precise extent of the ejection electrodes 9 will depend upon the particular design and purpose of the printer.
- FIG 2 a perspective schematic view of the printing apparatus operating in the method of the present invention is shown.
- a first print head 1 ejects ink in the horizontal direction with respect to the ground, and prints on the non-absorbing substrate which is held a plane perpendicular to the ground.
- the printing apparatus 30 comprises a first print head 1 , a printer main body 31 having a mount (not shown) on which the print head is mounted.
- the print head can be moved in three dimensions relative to the substrate 32 so that images can be printed on the substrate. Either the print head or the substrate can be moved to effect printing.
- a second printer main body 34 having a second printhead 1a, is provided and is arranged such that it can print on the side of the substrate that is opposite to the side printed by print head 1 to allow both sides of the substrate to be printed simultaneously. Not shown are ink supply and return paths.
