2. Description of the Related Art
Silk screen printing is a conventional printing technique that uses an ink-blocking stencil or mesh screen fabric that forms patterned open areas that allow for the transfer of ink or other indicia media which can be pressed through the stencil providing a sharp-edged indicia image onto a surface or a substrate. Ink is fluidly-applied as a pool or huddle of fluid ink poured onto the screen stencil, and a squeegee is used to force or press the ink past and through the threads of the woven mesh screen onto the open areas for printing. Generally, screen printing is a stencil method of print making in which a design is imposed on a screen of crafted of fine mesh, with blank areas coated with an impermeable substance, and ink is forced through the mesh onto the printing surface, and the screen then removed. While a common use for silk screen printing is for textiles or garments, the technique is used on thousands of items, including solid surface consumer items such as clock and watch faces, balloons, and many other products. The technique has even been adapted for more advanced uses, such as laying down conductors and resistors in multi-layer circuits using thin ceramic layers as the substrate.
A variety of inks may be used in the screen printing process. Some such inks include: magnetic ink—of the type disclosed in U.S. Pat. No. 7,192,628, which is hereby incorporated by reference in its entirety; discharge inks—used to print lighter colors onto dark background fabrics, they work by removing the dye in the garment—this means they leave a much softer texture; expanding ink (puff)—an additive to plastisol inks which raises the print off the garment, creating a 3D look and feel; flocking—consisting of a glue printed onto the fabric and then foil or flock (or other special effect) material is applied for a mirror finish or a velvet touch; four color process or the CMYK color model—artwork is created and then separated into four colors (CMYK) which combine to create the full spectrum of colors needed for photographic prints; glitter/shimmer—metallic flakes are suspended in the ink base to create this sparkle effect; gloss—a clear base laid over previously printed inks to create a shiny finish; metallic—similar to glitter, but smaller particles suspended in the ink; mirrored silver—a highly reflective, solvent based ink; nylobond—a special ink additive for printing onto technical or waterproof fabrics; plastisol—the most common ink used in commercial garment decoration; PVC and Phthalate Free—ink having the benefits of plastisol but without the two main toxic components; suede ink—suede is a milky colored additive that is added to plastisol; and water-based inks—which penetrate the fabric more than the plastisol inks and create a much softer feel.
Screen printing is a versatile printing technique. The surface does not have to be printed under pressure and it does not have to be planar. Screen printing inks can be used to work with a variety of materials, such as textiles, ceramics, wood, paper, glass, metal, and plastic. As a result, screen printing is used in many different industries, including: Balloons, Clothing, Decals, Medical devices, Printed electronics, including circuit board printing, Product labels, Signs and displays, Snowboard graphics, Textile fabric, Thick film technology, and Semi-conductors material.
Traditionally, garment decoration has relied on screen printing for printing designs on garments including t-shirts; recently, new methods and technologies have become available. Digital printing directly onto garments using modified consumer-quality, and task-specific designed inkjet printers. Screen printing, however, has remained an attractive, cost-effective, and high production-rate method of printing designs onto garments. Digital printing directly onto garments is referred to as DTG or DTS representing Direct To Garment or Direct To Shirt. DTG or DTS direct printing has advantages and disadvantages compared to screen printing. One noted advantage of DTG/DTS is number of visually perceived colors and the obvious photo-reproduction and photo-like print. DTG/DTS is often WYSIWYG (an acronym far What You See Is What You Get), whereas screen printing often requires skilled artistic modification and then must be photo reproduced onto screens and printed. DTG/DTS has the advantage of quick one-off designs and small quantity orders where the screen printing process involves several independent time consuming steps. Screen printing is a production method and quickly overtakes DTG/DTS in cost per print as the higher the volume the lower cost per print becomes, screen printing also has the advantage of a large selection of different types of inks that are all considerably less expensive per garment than DTG/DTS inks.
Screen printing of T-shirts and the like is typically carried out in the following manner. A printing screen is constructed by covering a frame with a screen of very fine mesh, usually constructed of silk, nylon or similar filament. The holes in the screen are selectively filled by well-known procedures so as to leave unfilled holes in the pattern of design to be printed. The T-shirt to be printed on is placed on a table or shirt board and the screen placed on top of the shirt. A suitable ink is then spread across the screen in fluid form and pressed through the holes in the screen with a squeegee. This leaves the desired ink pattern on the shirt.
Known techniques for screen printing of T-shirts and the like are time consuming and difficult, and extremely costly where mechanisms are used. For example, screen printing utilizing a vacuum has been applied in the past to paper.
Used in conjunction with the screen printing process are stenciled designs. These are typically applied to a surface, for example an article of clothing, and paint or ink can be applied through the cutout design onto the surface. These stencils are formed with cutout areas that correspond to various portions of the design to be created, In applying the design, the stencil or stencils usually are taped or otherwise secured to the surface where the stenciled design is to be applied. Commonly, the paint or ink is applied through the cutout areas with a brush or a sponge. However, paint is sometimes applied by different means such as, for example, by spraying the paint through the cutout areas or by rolling the paint over the stencil and through the cutout areas. In any event, the paint is applied to the surface through the cutout areas of a stencil, whereupon the stencil is removed leaving the resulting design on the surface.
A general consequence of the use of prior art methods has been that skillful application of high quality designs comes only after substantial experience in applying the designs, as a process of physical skill. It has been difficult in the past for a novice or inexperienced person to apply the designs with the same quality results as an experienced application. Also, to print multiple copies of the screen design on garments in an efficient manner, amateur and professional printers usually use a screen printing press. Many companies offer simple to sophisticated printing presses. Most of these presses are manual. A few industrial-grade-automatic printers require minimal manual labor and increase production significantly but such devices are expensive and bulky—designed for the mass producer—and not convenient or economical for individual users.
Accordingly, there exists a need for an inexpensive, convenient, and easy-to-use method, kit, and device that addresses the problems and shortcomings of the prior methods and apparatuses.
The invention relates to a ready to use screen printing system, device, kit, and method that includes a tacky screen of a design pattern (screen), and a single-use or multi-use hand-held indicia-printing device. More particularly, the present invention provides a full set of ready to use, disposable use printing kits which provides a printed pattern on any object in a matter of minutes, and may optionally be combined multiple ink containers or packets in a kit form.
In accordance with one aspect of this invention, a hand-held, screen ink and applicator utilizing a squeegeeing feature and structure, and method for utilizing same, is provided. An applicator device is provided which comprises an ink packet affixed to or removably-attached to a rigid backing or substrate member. The ink packet is attached in a manner that during use enable the rigid substrate or backing to act as an integrated squeegee as the ink is pressed out of the packet and onto the surface to provide an even amount of ink over the desired surface. In accordance with one aspect of the invention, the applicator is disposable. In accordance with one aspect of the invention, the applicator is multi-use, and for example, may be re-sealable between uses.
In still another aspect of the invention, one or more screen designs may be provided along with the applicator device (or devices to include multiple color ink packets) to comprise a complete screen printing system, set or kit. The screen printing set in accordance with the present invention may include one or more stencil design sheets of various designs, optionally made of substantially transparent plastic, such that each stencil sheet has a distinct portion of the overall design represented by cutout areas in the sheet. The patterned screen sheets are provided preferably with a releasably-self-sticky side to be easily amounted to a surface to-be-printed.
This would enable the user to readily apply different colors to different portions of the overall design. The sheets may be used in sequence to apply the design to a surface and with each sheet the portions of the design not being immediately applied to the surface are visible to the user on the stencil sheet itself. That is, a first stencil sheet may be for application of a first portion of the design to the surface and has cutout portions corresponding to the first portion of the design. Similarly, a second stencil sheet may be for application of a second portion of the design to the surface and has cutout areas corresponding to the second portion of the design. Of course, more than two stencil sheets may be used as well.
Once the first portion of the design is applied through the cutout areas of the first stenciled sheet, this stencil sheet is removed and the ink is allowed to dry. Once dry, the second stencil sheet is applied. The design on the second stencil sheet is aligned with the previously applied design by aligning the previously applied first portion of the design with that portion as printed on the second stencil sheet. In this manner, near perfect alignment is easily achieved. The second portion of the design can then be applied through the cutout areas of the second stencil sheet.
One aspect of the present invention is to provide an inexpensive reliable apparatus, device, kit, and method for screen printing on any other textile articles.
Another aspect of the present invention is to provide an applicator device for screen printing that is inexpensive and optionally disposable while also enabling a multi-use configuration.
Another aspect of the present invention is to provide an applicator device for screen printing that is inexpensive but may be reused, or may be multi-use, and may optionally include a resealable feature.
Another aspect of the invention is to provide a screen printing applicator device and method that is easy to use.
Another aspect of the invention is to provide a complete screen printing kit comprising a variety of ink colors and screen designs.

As depicted in the perspective view, the screen ink-applicator device 1 may comprise a housing 2 which is preferably removable and substantially surrounds the ink packet 3, and a detachable tear sealing strip 5 that seals a pre-cut ink packet 3. The sealing side of the strip 5 may be coated with a layer of adhesive material to tightly seal the pre-cut opening of packet 3.
Pre-designed pattern sheet 30 may comprise two layers of sheet materials, a smooth plastic sheet 40 and a pre-patterned sheet 10 that is made of fine mesh like fabric material where the darker areas are paint-blocked and the light areas are paint-penetrable. Sheet 10 may be configured to be self-sticky in order to be easily attached into a surface, and sheet 40 is attached to the sticky side of sheet 10 to protect the glue material and to allow sheet 10 to be freshly peeled off to attach to the surface to be painted with the pattern that sheet 10 provides.
The screen ink-applicator 1 may contain a pre-cut opening on the ink-packet 3 ready to use or it may contain a sealed ink-packet 3 that needs to be cut open before using.
As shown in
For a screen ink-applicator 1 that contains a pre-cut opening on the ink-packet 3, a housing 2 may be provided to provide aesthetic packaging and a sealing strip 5 is attached to seal the opening 6 (

Referring additionally to
If not already done, the user should position the desired screen design 10 in place on the surface of, for example, shirt 9 where the design is to be placed (step 14). The user then holds applicator 1 between the thumb and fingers preferably such that the thumb presses on packet 3 while the fingers press on the support 7 (step 15). This positioning will enable the user to depress on the packet 3 to force the ink out of the packet 3 through opening 6 at the desired time. Then, the user, while holding the applicator 1 and just discussed, positions the applicator 1 adjacent the screen 10 such that the bottom edge of support 7 comes in contact with screen 10 (step 16).
Once applicator 7 is in the desired location on screen 10, the user moves the applicator 7 in a generally longitudinal direction across screen 10 while depressing on packet 3 such that ink is forced out of packet 3 into the cutout 20 of screen 10 (step 17). The user preferably maintains contact between the bottom edge of support 7 and screen 10 while ink is being forced out of packet 3 and onto screen 10. This will allow the bottom edge of support 7 to act as a squeegee thereby sweeping away any excess ink on screen 10 while pushing such ink into the cutout 20 in screen 10 and onto the desired surface 9. The user then determines of ink has been forced into the entire design on screen 10 (step 17A), and then repeats step 17 until the entire cutout 20 on screen 10 has been filled with ink (step 18). Once the user determines that ink has been supplied to the entire cutout 20, the screen 10 may be removed from surface 9 so that it may dry. Optionally, the user may then use a second design screen of a different design and repeat the process with the same or a different color ink.
The screen sheet may be designed to any pattern by print-blocking the mesh-like fabrics. For example, in
For example, the screen printing system may optionally comprise a first screen and a second screen. The screens are preferably made of thin, substantially transparent plastic sheet material that is light, inexpensive, and durable. However, the screens could be formed of any substantially transparent material. Further, while two screens are discussed here for clarity of explanation and description of the invention, it will be understood that the present invention may be embodied in screen sets of three or more screens, depending upon the complexity of the finished design to be applied and the number of different colors to be used to complete the design. For example, a screen set may be designed for the application of a red rose to a surface, where the rose both a flower and a stem. In reality, the red rose would be colored red (or any other colored rose), while the stem would be colored shades green.
While a simple flower design made up of two portions has been discussed for clarity of explanation, it will be understood that designs of any desired level of complexity and with any number of different portions can be achieved through application of the present invention. For example, a cluster of roses might be applied with five different portions of the design to be colored five different colors of roses. Such a complex design could be applied easily with the present invention with five stencil sheets, each having cutout areas corresponding to a different portion of the design, and using five different applicators each with a different one of the five desired color inks. Accordingly, the simplicity of the present invention allows for the simple and efficient application of multiple color inks to various parts of a design to be applied to a surface.
Registration lines are optionally printed on the sides of the screens, for purposes of aligning and registering the designs on the two screens. The registration lines are positioned on the screens so that when the second screen is laid atop the first screen and the lines are registered with each other, then the visibly depicted portions of the image on each sheet align with and show through the corresponding cutout portion on the other sheet. Thus, when the two sheets are overlaid and registered, a complete image of the finished design as it should look when applied to the surface is presented, and there is no need for a separate printed depiction of the finished design.
In another embodiment of the present invention, the applicator and screen print designs may be assembled into a complete kit. For example, referring again to the multiple rose example discussed above, a screen print system or kit may preferably comprise a plurality of applicators of various colors, each designed in accordance with applicator 1, and a plurality of print screens each having a rose design cutout which may be used together or individually to create variety of different colored designs. Alternatively, any number of different sizes, shapes, colors, designs, etc. may be used in accordance with the invention.
As shown in
Once the ink has dried on the surface, the second screen is then positioned or otherwise affixed to the surface overlying the previously applied first portion of the design. In order to align the second screen with the applied first portion, the user need only line up the visibly depicted portion with the first portion of the design that was previously applied to the surface. Upon such alignment, the second portion of the design corresponding to the cutout portion in the second screen is properly aligned and oriented with respect to the previously applied first portion. Using applicator 1 having a second color ink, ink is then applied through the cutout portion in the second screen to complete the design on the surface.
The screen print system and method according to this embodiment of the invention has been found to be superior to prior art methods because, in part, the need to judge color characteristics of a color being immediately applied relative to colors of the design not being immediately applied by referring to separate printed drawings of the final design is eliminated. Rather, the portions of the final design not being immediately applied are always visible to the user right on each screen as the design is being applied. The result is a completed design wherein the elements are properly aligned with respect to each other and display color combinations that are true and accurate. The present invention is found to be useful and helpful to novices and those with little experience in applying such screen print designs.
The invention has been described in terms of preferred embodiments and methodologies. It will be obvious to those of skill in this art, however, that various modifications or extensions may be made to the illustrated embodiments. As mentioned above, for example, three, four, or even more stencil sheets could be used to create complex designs having many portions of different colors.
These alternative operative constructions include, as non-limiting examples, re-sealable pouches, or the provision of a series of pouches that may be adaptively and operatively releasably secured to an application, with a hook+loop system (Velcro for example), or with other means. In this series system, multiple ink pouches may be sold with a single substrate, and a user-selection may occur for a desired ink for use with a particular stencil.
It will also be understood that the phrases used herein are descriptive and non-limiting in use, for example a pouch or container or bag is a bounded volume for containing the pigment medium (e.g., ink, paint, etc.), all without departing from the scope and spirit of the present invention.
Having described at least one of the preferred embodiments of the present invention with reference to the accompanying drawings, it is to be understood that such embodiments are merely exemplary and that the invention is not limited to those precise embodiments, and that various changes, modifications, and adaptations may be effected therein by one skilled in the art without departing from the scope or spirit of the invention as defined in the appended claims. The scope of the invention, therefore, shall be defined solely by the following claims. Further, it will be apparent to those of skill in the art that numerous changes may be made in such details without departing from the spirit and the principles of the invention. It should be appreciated that the present invention is capable of being embodied in other forms without departing from its essential characteristics.
