Definitions
- the present invention relates to a method for printing an image wherein the border region of an image element is fixated.
- an image may be created by one or more image elements which are formed by jetting ink droplets of a particular color onto a print medium in a specific droplet pattern.
- the created image may contain one or more image elements such as an individual text character or a single colored shape like the part of a logo.
- ink jetted on a print medium may tend to spread and flow into the medium or into neighboring ink droplets. Images containing more than one image element wherein the image elements are adjacent to each other, such as a multicolor logo, may thus show a so-called bleeding effect at the border region of such an image element resulting in a vague or blurry image and/or image element.
- US 2011/211014 describes an inkjet image forming method including applying a treatment liquid onto the recording medium, wherein the treatment liquid comprises an aggregation agent.
- the object of the invention is achieved in a method for printing an image using an ink, wherein the method comprises the steps of jetting ink droplets onto a medium creating an image element, selectively jetting an accelerator composition at a border region of the image element, applying a treatment step to the created image element thereby activating the accelerator composition to fixate the border region of said image element.
- the ink droplets may be jetted using an ejection unit configured to, in operation, eject droplets of an ink composition to form an image or an image element.
- the accelerator composition may be jetted using an ejection unit similar to the ejection unit jetting ink droplets.
- the accelerator composition may be jetted selectively in regions where bleeding of the ink is most conspicuous such as at the border region of an image element.
- the accelerator composition may be jetted at the border region of the image element while the remainder of the image element essentially remains uncovered by the accelerator composition.
- the ejection unit for jetting the accelerator composition and the ejection unit for jetting the ink droplets may be a print head unit.
- the print head unit may be a piezoelectric actuated print head or a thermally actuated print head.
- the treatment step may be performed by a treatment unit.
- the treatment unit may apply a treatment such as UV radiation or heat onto the entire image thereby activating the accelerator composition which is selectively jetted at the regions where bleeding of the ink is most conspicuous.
- the treatment unit may be a source of electromagnetic radiation suitable for activating the accelerator. Said source may be, for instance, a UV radiation source such as a UV lamp.
- the treatment unit may be a heating source such as a heater.
- the accelerator composition may react only with the ink droplets upon activation by means of the treatment unit and thus the accelerator composition and the ink droplets may have time to mix with each other before interaction between both occurs.
- the treatment step may be sufficient to activate the accelerator composition without curing the rest of the image element that essentially remains uncovered by the accelerator composition.
- the accelerator composition jetted regionally may be activated to fixate only the border region of an image element while applying the treatment step to the whole image.
- the border region of the image element may be the outer edge of the image element where the outer edge of said image element meets the outer edge of another image element and/or where the outer edge of the image element meets a region of the medium uncovered by either ink droplets and/or the accelerator composition.
- the border region may be the outer edge of an image element where bleeding of ink droplets either into another image element and/or towards an empty region of the medium may occur.
- the accelerator composition is jetted after jetting ink droplets.
- first ink droplets may be jetted onto a medium creating an image element and after the image element is created the accelerator composition may be jetted at a border region of the created image element. It is an advantage of the present embodiment that all the ink droplets are on the same plane and thus all ink droplets may interact with the medium onto which they are jetted.
- the accelerator composition is jetted before jetting ink droplets.
- first the accelerator composition is jetted at a border region of an image element to be created and after the accelerator composition is jetted the ink droplets are jetted to create an image element. It is an advantage of the present embodiment that the accelerator composition is positioned under the visible image element rather than on top of the visible image element.
- the ink used to print an image is a UV-curable ink.
- the ink droplets jetted onto a medium creating an image element can be cured by the application of UV radiation after the entire image is printed. It is an advantage of the present embodiment that the printed image may be fixated before the image may be dried and thus prevent bleeding of the image before the image is dried.
- the treatment step to activate the accelerator composition comprises the application of UV radiation onto the image element.
- the accelerator composition may be activated by means of UV radiation doses sufficient to activate the accelerator composition. This UV radiation doses may also partially cure the ink droplets.
- the accelerator composition jetted is in contact with the ink droplets jetted in the same position, the accelerator composition and the ink droplet may interact with each other and the UV radiation doses sufficient to activate the accelerator composition due to the interaction with the ink droplets may be capable of curing the ink droplets interacting with the accelerator composition. It is an advantage of the present embodiment that only the ink droplets in contact with the accelerator composition are affected by the treatment step.
- the accelerator composition comprises a thiol.
- the thiol acts as a polymerization accelerator when the accelerator composition is in contact with an ink droplet and activated by means of UV radiation.
- a thiol may be multifunctional mercapto compounds such as, for example, pentaerythritol tetra (3-mercaptopropionate), ethoxylated trimethylolpropane Tri (3-mercaptopropionate), or pentaerythritol tetramercapto-acetate.
- the accelerator composition comprises a transition metal such as Co 2+ , Fe 3+ , or Mn 2+ .
- the transition metal acts as a polymerization accelerator when the accelerator composition is in contact with an ink droplet and activated by means of UV radiation.
- a transition metal may be a metal ion complex such as, for example, cobalt(II)2-ethylhexanoate or copper(II)acetate.
- a printer comprises an ejection unit configured to in operation eject droplets of an ink composition, an ejection unit configured to in operation eject droplets of an accelerator composition, a treatment unit for applying a treatment step to a created image element thereby activating the accelerator composition to fixate the border region of an image element, and a control unit configured to perform the method for printing an image using an ink, wherein the method comprises the steps of jetting ink droplets onto a medium creating an image element, jetting an accelerator composition at a border region of the image element, applying a treatment step to the created image element thereby activating the accelerator composition to fixate the border region of said image element.
- the printer may thus be configured to perform a method according to the present invention
- the treatment unit for applying a treatment step comprises a UV radiation source.
- the UV radiation source is an UV lamp positioned close to the ejection unit to apply radiation almost immediately after jetting of the ink droplets and jetting of the accelerator composition. It is an advantage of the present embodiment that the UV radiation source is capable of activating the accelerator composition without fully curing the entire image element right after both the accelerator composition and ink droplets are jetted.

Description
- The present invention relates to a method for printing an image wherein the border region of an image element is fixated.
- In a copier, a printer or any other machine an image may be created by one or more image elements which are formed by jetting ink droplets of a particular color onto a print medium in a specific droplet pattern. Thus when an image is created using an ink, the created image may contain one or more image elements such as an individual text character or a single colored shape like the part of a logo. When printing an image using an inkjet printer, ink jetted on a print medium may tend to spread and flow into the medium or into neighboring ink droplets. Images containing more than one image element wherein the image elements are adjacent to each other, such as a multicolor logo, may thus show a so-called bleeding effect at the border region of such an image element resulting in a vague or blurry image and/or image element.
-
US 2011/211014 describes an inkjet image forming method including applying a treatment liquid onto the recording medium, wherein the treatment liquid comprises an aggregation agent. - When printing an image using a UV-curable ink, this bleeding effect at the border region of an image element can be prevented by selectively radiating and curing the UV ink at the border region. This can be seen for instance in patent
US 7,607,773 . This method, however, requires a UV radiation source and control unit capable of radiating individual ink droplets or a small group of ink droplets that constitute a pixel. Radiation of an individual ink droplet or a small group of ink droplets will thus be difficult and expensive. - It is therefore an object of the present invention to overcome the disadvantage of the prior art by providing a method of for printing an image wherein the border region of an image element is fixated in a simple and cheap manner.
- The object of the invention is achieved in a method for printing an image using an ink, wherein the method comprises the steps of jetting ink droplets onto a medium creating an image element, selectively jetting an accelerator composition at a border region of the image element, applying a treatment step to the created image element thereby activating the accelerator composition to fixate the border region of said image element. The ink droplets may be jetted using an ejection unit configured to, in operation, eject droplets of an ink composition to form an image or an image element. The accelerator composition may be jetted using an ejection unit similar to the ejection unit jetting ink droplets. The accelerator composition may be jetted selectively in regions where bleeding of the ink is most conspicuous such as at the border region of an image element. Thus the accelerator composition may be jetted at the border region of the image element while the remainder of the image element essentially remains uncovered by the accelerator composition. The ejection unit for jetting the accelerator composition and the ejection unit for jetting the ink droplets may be a print head unit. The print head unit may be a piezoelectric actuated print head or a thermally actuated print head. The treatment step may be performed by a treatment unit. The treatment unit may apply a treatment such as UV radiation or heat onto the entire image thereby activating the accelerator composition which is selectively jetted at the regions where bleeding of the ink is most conspicuous. The treatment unit may be a source of electromagnetic radiation suitable for activating the accelerator. Said source may be, for instance, a UV radiation source such as a UV lamp. Alternatively, when the accelerator composition may be activated by for instance heat, the treatment unit may be a heating source such as a heater. The accelerator composition may react only with the ink droplets upon activation by means of the treatment unit and thus the accelerator composition and the ink droplets may have time to mix with each other before interaction between both occurs. By treating the created image element with a low dosage of UV radiation or heat, the treatment step may be sufficient to activate the accelerator composition without curing the rest of the image element that essentially remains uncovered by the accelerator composition. Thereby the accelerator composition jetted regionally may be activated to fixate only the border region of an image element while applying the treatment step to the whole image. The border region of the image element may be the outer edge of the image element where the outer edge of said image element meets the outer edge of another image element and/or where the outer edge of the image element meets a region of the medium uncovered by either ink droplets and/or the accelerator composition. Thus the border region may be the outer edge of an image element where bleeding of ink droplets either into another image element and/or towards an empty region of the medium may occur.
- In an embodiment, the accelerator composition is jetted after jetting ink droplets. In this embodiment, first ink droplets may be jetted onto a medium creating an image element and after the image element is created the accelerator composition may be jetted at a border region of the created image element. It is an advantage of the present embodiment that all the ink droplets are on the same plane and thus all ink droplets may interact with the medium onto which they are jetted.
- In an embodiment, the accelerator composition is jetted before jetting ink droplets. In this embodiment, first the accelerator composition is jetted at a border region of an image element to be created and after the accelerator composition is jetted the ink droplets are jetted to create an image element. It is an advantage of the present embodiment that the accelerator composition is positioned under the visible image element rather than on top of the visible image element.
- In an embodiment, the ink used to print an image is a UV-curable ink. In this embodiment, the ink droplets jetted onto a medium creating an image element can be cured by the application of UV radiation after the entire image is printed. It is an advantage of the present embodiment that the printed image may be fixated before the image may be dried and thus prevent bleeding of the image before the image is dried.
- In an embodiment, the treatment step to activate the accelerator composition comprises the application of UV radiation onto the image element. In this embodiment, the accelerator composition may be activated by means of UV radiation doses sufficient to activate the accelerator composition. This UV radiation doses may also partially cure the ink droplets. When the accelerator composition jetted is in contact with the ink droplets jetted in the same position, the accelerator composition and the ink droplet may interact with each other and the UV radiation doses sufficient to activate the accelerator composition due to the interaction with the ink droplets may be capable of curing the ink droplets interacting with the accelerator composition. It is an advantage of the present embodiment that only the ink droplets in contact with the accelerator composition are affected by the treatment step.
- In the invention, the accelerator composition comprises a thiol. In the invention, the thiol acts as a polymerization accelerator when the accelerator composition is in contact with an ink droplet and activated by means of UV radiation. Such a thiol may be multifunctional mercapto compounds such as, for example, pentaerythritol tetra (3-mercaptopropionate), ethoxylated trimethylolpropane Tri (3-mercaptopropionate), or pentaerythritol tetramercapto-acetate.
- In an embodiment, the accelerator composition comprises a transition metal such as Co2+, Fe3+, or Mn2+. In this embodiment, the transition metal acts as a polymerization accelerator when the accelerator composition is in contact with an ink droplet and activated by means of UV radiation. Such a transition metal may be a metal ion complex such as, for example, cobalt(II)2-ethylhexanoate or copper(II)acetate.
- In an aspect of the invention, a printer comprises an ejection unit configured to in operation eject droplets of an ink composition, an ejection unit configured to in operation eject droplets of an accelerator composition, a treatment unit for applying a treatment step to a created image element thereby activating the accelerator composition to fixate the border region of an image element, and a control unit configured to perform the method for printing an image using an ink, wherein the method comprises the steps of jetting ink droplets onto a medium creating an image element, jetting an accelerator composition at a border region of the image element, applying a treatment step to the created image element thereby activating the accelerator composition to fixate the border region of said image element. The printer may thus be configured to perform a method according to the present invention
- In an embodiment the treatment unit for applying a treatment step comprises a UV radiation source. In this embodiment, the UV radiation source is an UV lamp positioned close to the ejection unit to apply radiation almost immediately after jetting of the ink droplets and jetting of the accelerator composition. It is an advantage of the present embodiment that the UV radiation source is capable of activating the accelerator composition without fully curing the entire image element right after both the accelerator composition and ink droplets are jetted.

Fig. 1B shows an inkjet printing assembly 10. The inkjet printing assembly 10 comprises a medium support surface to support the medium 21 during printing. The medium support surface inFig. 1B is provided on aplaten 11 in the form of a drum rotatable in direction A, but may, alternatively, be a flat support surface. The medium support surface is preferably provided with suction holes for at least temporarily holding the medium 21 in a fixed position with respect to the medium support surface. The inkjet printing assembly 10 comprisesprint heads 12a - 12d, mounted on ascanning print carriage 13, or alternatively as a stationary page-wide array. Thescanning print carriage 13 is guided bysuitable guides print head 12a - 12d comprises anorifice surface 16, which orificesurface 16 is provided with at least oneorifice 17. The print heads 12a - 12d are configured to eject droplets of marking material onto the medium 21. The medium support surface, thecarriage 13 and the print heads 12a - 12d are controlled by suitable controlling means 6a, 6b and 6c, respectively. - The medium 21 is supplied in web form and may be composed of e.g. paper, cardboard, label stock, coated paper, plastic or textile. The medium 21 is moved in the sub-scanning direction A by the
platen 11 along fourprint heads 12a - 12d provided with a fluid marking material. - A
scanning print carriage 13 carries the fourprint heads 12a - 12d and may be moved in reciprocation in the main scanning direction B parallel to the medium support surface, such as to enable scanning of the medium 21 in the main scanning direction B. Any number of print heads may be employed. Preferably, at least oneprint head 12a - 12d per color of marking material is placed on thescanning print carriage 13, for example one forprint head 12a - 12d for each of the applied colors, usually black, cyan, magenta and yellow is present. Often, in a full-color printer, black marking material is used more frequently in comparison to differently colored marking material. Therefore,more print heads 12a - 12d containing black marking material may be provided on thescanning print carriage 13 compared toprint heads 12a - 12d containing marking material in any of the other colors. Alternatively, theprint head 12a - 12d containing black marking material may be larger than any of the print heads 12a - 12d, containing a differently colored marking material. - The
carriage 13 is guided byguides rods Fig. 1B . Thecarriage 13 may be driven along theguides - Each
print head 12a - 12d comprises anorifice surface 16 having at least oneorifice 17, in fluid communication with a pressure chamber containing fluid marking material provided in theprint head 12a - 12d. On theorifice surface 16, a number oforifices 17 is arranged in a single linear array parallel to the sub-scanning direction A. Eightorifices 17 perprint head 12a - 12d are depicted inFig. 1B , however obviously in a practical embodiment at least several hundreds oforifices 17 may be provided perprint head 12a - 12d, optionally arranged in multiple arrays. As depicted inFig. 1B , therespective print heads 12a - 12d are placed parallel to each other such thatcorresponding orifices 17 of therespective print heads 12a - 12d are positioned in-line in the main scanning direction B. This means that a line of image dots in the main scanning direction B may be formed by selectively activating up to fourorifices 17, each of them being part of adifferent print head 12a - 12d. This parallel positioning of the print heads 12a - 12d with corresponding in-line placement of theorifices 17 is advantageous to increase productivity and/or improve print quality. Alternativelymultiple print heads 12a - 12d may be placed on the print carriage adjacent to each other such that theorifices 17 of therespective print heads 12a - 12d are positioned in a staggered configuration instead of in-line. For instance, this may be done to increase the print resolution or to enlarge the effective print area, which may be addressed in a single scan in the main scanning direction. The image dots are formed by ejecting droplets of marking material from theorifices 17. - Upon ejection of the marking material, some marking material may be spilled and stay on the
orifice surface 16 of theprint head 12a - 12d. The ink present on theorifice surface 16, may negatively influence the ejection of droplets and the placement of these droplets on the medium 21. Therefore, it may be advantageous to remove excess of ink from theorifice surface 16. The excess of ink may be removed for example by wiping with a wiper and/or by application of a suitable anti-wetting property of the surface, e.g. provided by a coating. -
