[0002] This application claims priority to U.S. Patent Application Serial No. 63 / 187,975, filed May 13, 2021, entitled “Printing Compositions and Methods Therefor”, and U.S. Patent Application Serial No. 63 / 247,935, filed September 24, 2021, entitled “Printing Compositions and Methods Therefor”, the entire contents of each of which are incorporated herein by reference. Background Technology

[0003] This subject matter relates to printing compositions and methods, and more particularly to printing compositions and methods for use on polymer flexible and / or shrinkable substrates.

[0004] Inkjet printing is a well-known technology in which digital images are reproduced on a substrate by depositing droplets of ink onto the substrate.

[0005] In addition, high-speed printing systems have been developed for printing on webs of substrates such as shrinkable polymer films. Such materials typically exhibit both elastic and plastic properties, depending on one or more applied influences, such as force, heat, chemicals, electromagnetic radiation, etc. These properties must be carefully considered during system design because it may be necessary to: 1.) control material shrinkage during imaging so that the resulting imaged film can subsequently be used in shrink packaging processes, and 2.) avoid system control problems by minimizing the dynamic interactions between system components due to the elastic deformation of the substrate. These considerations also affect the process of registering printed content for accurate reproduction.

[0006] Specifically, flexible webs can be printed on one side (i.e., on one side) or on both sides (i.e., on both sides). In either case, the separately printed images, even if printed by a single printing unit (e.g., a multicolor imager unit), must be accurately registered to each other to minimize registration errors such as color shift, moiré patterns, and undesirable dot gain.

[0007] In addition, the use of water-based inks for commercial printing applications (including but not limited to inkjet printing) has been increasing, partly due to environmental and health concerns surrounding the volatile organic compounds (“VOCs”) emitted during the drying process in solvent-based compositions.

[0008] Health concerns become prominent when used in printing for the food industry. For example, Switzerland has enacted legislation regulating printing inks for food packaging. A list of components that can be used in printing inks has been compiled to remove substances considered carcinogenic, mutagenic, or reproductively toxic. Although this requirement exists only in Switzerland, the Swiss Ordinance on Materials and Articles in Contact with Food (SR 817.023.21), concerning printing inks and coatings, is widely accepted worldwide as a useful guide for creating inks and / or ink-absorbing compounds for indirect food contact purposes, such as for food packaging. The current version of the Swiss Ordinance on Materials and Articles in Contact with Food (SR 817.023.21) as of the date of this application is incorporated herein by reference in its entirety. For matters not covered in the current version of the Swiss Regulation on Food Contact Materials and Articles (SR 817.023.21) as of the date of this application, Annex 10, version 2.1 of the Swiss Regulation on Food Contact Materials and Articles (SR 817.023.21) dated December 1, 2020, is also incorporated herein by reference in its entirety regarding materials and articles intended to come into contact with food.

[0009] For general printing on porous or permeable substrates or webs, the water in the ink is partially absorbed by the surface of the web during the drying process. However, problems arise when water-based inks are deposited on impermeable webs such as plastic webs. Because the ink dries primarily through evaporation during drying and / or curing, the lack of penetration or absorption into the web itself causes individual ink droplets to spread across the web surface. If these individual ink droplets spread and come into contact with each other, the desired image quality can be adversely affected due to the coalescence of adjacent droplets. This is a common problem during high-speed printing.

[0010] Furthermore, to achieve desired properties such as appropriate adhesion and abrasion resistance in the current system, multiple layers of inks and coatings may be necessary. For example, a primer layer can be laid on the web, followed by the deposition of an ink layer in the same location as the primer layer. Additionally, an overprinted varnish or coating can be laid on top of the ink layer to achieve appropriate abrasion resistance.

[0011] Another problem that may occur during high-speed printing is "ink re-transfer" or "ink stripping," in which the ink used to print the image has not dried sufficiently before contacting another part of the web system, such as the idler roller, and thus the ink is unintentionally transferred from the printing area to the roller.

[0012] Furthermore, if the temperature of the substrate exceeds the substrate dimensional integrity threshold during the printing process, the substrate may shrink and / or deform, resulting in unusable products.

[0013] The above discussion provides only general background information and is not intended to be used to help determine the scope of the subject matter for which protection is sought. Summary of the Invention

[0029] Other aspects and advantages will become apparent upon consideration of the following detailed description and accompanying drawings, in which the same reference numerals denote the same structures throughout the specification.

[0030] This brief description of the invention is intended only to provide a brief overview of the subject matter disclosed herein according to one or more illustrative embodiments, and is not intended as a guide for interpreting the claims or for defining or limiting the scope of the invention, which is defined by the appended claims. This brief description is provided to introduce illustrative choices of concepts in a simplified form, which will be further described in the detailed description below. This brief description is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. The claimed subject matter is not limited to embodiments that address any or all of the disadvantages pointed out in the background. Attached Figure Description

[0031] To understand the features of the invention, reference can be made to certain embodiments illustrated in the accompanying drawings. However, it should be noted that the drawings illustrate only certain embodiments of the invention and should not be considered as limiting its scope, as the scope of the invention encompasses other equally effective embodiments. The drawings are not necessarily drawn to scale, and the emphasis is generally placed on features illustrating certain embodiments of the invention. In the drawings, the same numerals are used throughout the various views to indicate the same parts. Therefore, for a further understanding of the invention, reference can be made to the following detailed description, which is read in conjunction with the accompanying drawings, in which:

[0032] The only figure is a simplified block diagram of an exemplary system for printing images and / or text on a substrate. Detailed Implementation

[0033] The figure illustrates an exemplary system 20 for printing content (e.g., images and / or text) on a substrate such as a shrinkable plastic film for food-grade applications. System 20 may include a stand-alone device for printing monochrome images, or it may be used in conjunction with other systems equivalent to System 20 to sequentially print multiple colors. System 20 can be used for printing on any flexible polymer material that is dimensionally stable or unstable during processing for any application (e.g., food-grade or non-food-grade applications). In one embodiment, system 20 operates at high speeds, such as in the range of 0 to 1000 feet per minute (fpm). In one embodiment, system 20 operates in the range of 0 to 500 fpm. In one embodiment, system 20 operates in the range of 0 to 350 fpm, but the system can operate at different speeds as needed or desired.

[0034] The illustrated system 20 is capable of printing images and / or text on one or both sides of a substrate (i.e., system 20 is capable of single-sided and / or double-sided printing).

[0035] In the illustrated embodiment, the first side of the substrate can be imaged by a series of specific units of system 20 during the first pass. If system 20 is capable of double-sided printing, the substrate is then flipped, and the other side of the substrate can be imaged by all specific units of system 20 or by sub-integrated images of only specific units during the second pass.

[0036] Furthermore, the illustrated system 20 may include a fully digital system utilizing only an inkjet printer. Inkjet technology offers on-demand ink dispensing capabilities, thus allowing for a high level of color control and image customization, among other advantages.

[0037] Some inkjet heads are well-suited for applying high-opacity base inks, which may be necessary so that other inks printed on them can receive sufficient reflected white light. Due to achievable droplet sizes and volumes, droplet velocities and jet straightness, as well as physical properties such as surface tension and viscosity, some printhead technologies are better suited for white inks compared to non-white inks.

[0038] Printing water-based inks on flexible and / or shrinkable films presents numerous challenges and requires fluid management, temperature control, and closed-loop processes. Therefore, in this system, for example, the ability to maintain a high-quality color gamut at high speeds is further controlled by sensors, which may include one or more calibration cameras to continuously fine-tune the system over long runs.

[0039] As used herein, the phrase “heat-shrinkable” refers to a film exhibiting at least 10% total free shrinkage (i.e., the sum of free shrinkage in both the longitudinal and transverse directions) at 85°C (185℉), as measured according to ASTM D2732-14 (2020), which is hereby incorporated herein by reference in its entirety. All films exhibiting less than 10% total free shrinkage at 85°C (185℉) are referred to herein as non-heat-shrinkable. Heat-shrinkable films may have at least 15%, or at least 20%, or at least 30%, or at least 40%, or at least 45%, or at least 50%, or at least 55%, or at least 60%, or at least 65%, or at least 70% total free shrinkage at 85°C (185℉), as measured by ASTM D2732-14 (2020). Heat shrinkability can be achieved by orientation in the solid state (i.e., at a temperature below the glass transition temperature of the polymer). The total orientation factor used (i.e., lateral stretch and longitudinal stretch) can be any desired factor, such as at least 2X, at least 3X, at least 4X, at least 5X, at least 6X, at least 7X, at least 8X, at least 9X, at least 10X, at least 16X, or 1.5X to 20X, 2X to 16X, 3X to 12X, or 4X to 9X.

[0040] The web 24, which may be a polymer web such as a polyolefin web, can be treated by a surface energy modification system, such as a conventional type of corona treatment unit 26, to increase the surface energy of the web 24. Corona treatment addresses imaging conditions that may arise when applying a large number of closely spaced ink droplets to a low surface energy impermeable material, where, without compensation, the applied ink may become distorted due to coalescence effects. The corona treatment unit 26 can treat both sides of the web 24 simultaneously. The web guide 28, which may be conventional, controls the lateral position of the web 24 in a closed-loop manner, guiding the corona-treated web 24 to the imager unit 30. The drying unit 32 dries the material applied to the web 24 by the imager unit 30. The material applied by the imager unit 30 can be deposited on the entire web 24 or selectively applied only to a portion of the web 24.

[0041] Units 30 and 32 are shown in the figure as a first imager unit and a first dryer unit 32, because one or more additional optional imager units and / or dryer units may be operated to deposit and / or dry additional material applied to the web 24. These units may be upstream or downstream of units 30, 32.

[0042] The imager unit 30 may include an inkjet printhead arranged to apply monochrome or multicolor inks, such as primary color printing inks CMYK and / or secondary color printing inks orange, magenta, and green OVG and / or optional spot color inks S, to the web 24 at relatively high resolution. The inclusion of CMYK and OVG inks in the color printing enables the reproduction of detailed images and high-quality graphics with an extended color gamut on the web 24.

[0043] In one embodiment of the system 20 using inkjet technology, a first imager unit 30 of an inkjet printer may optionally apply transparent ink and / or white ink having a dispersion of a white colorant such as titanium dioxide. One or more downstream units, which may be equivalent to or different from the imager unit 30 and the dryer unit 32, may deposit one or more non-white inks on their backward web, at least in the portion that receives material from the first imager unit 30.

[0044] As is apparent from the foregoing, the printing composition, such as the ink formulation, can be applied directly to the surface of the web 24 or to a layer of white or transparent ink already printed on the web 24, thereby enabling the printed image to adhere to the web 24 and providing chemical interaction with the printed composition to optimize color fidelity and overall image quality. Furthermore, the printing composition may contain any colorant, such as pigments, dyes, or any other colorant and / or colorant dispersions / emulsions, which can be applied directly to the surface of the web 24 or to a layer of white or transparent ink already applied directly to the surface of the web 24.

[0484] The overall viscosity of the above-disclosed printing compositions 1 to 7, which can be deposited via inkjet printing technology, will vary depending on the printhead used. In one exemplary embodiment, the printing composition viscosity is 2 cP to 10 cP. In one embodiment, the printing composition viscosity is 3 cP to 10 cP. In one embodiment, the printing composition viscosity is 4 cP to 7 cP. Viscosity measurements were taken using a Brookfield viscometer at 25°C and 100 rpm using an ultra-low viscosity setting, as per ASTM D7867-13 (2020), which is hereby incorporated herein by reference in its entirety. Dynamic surface tension measurements were taken using the standard test method for dynamic surface tension using a rapid bubble technique, as per ASTM D3825-90, the current version of which is hereby incorporated herein by reference in its entirety as of the date of this application. The pH measurement was performed using standard test methods for the pH of water, such as ASTM D1293-18, the current version of which is hereby incorporated herein by reference in its entirety as of the date of this application.

[0485] Furthermore, the pH of the above-disclosed printing composition that can be deposited via inkjet printing technology will vary depending on the printhead used, but will not be less than 7.

[0486] Furthermore, due to their exemplary ability to dry and / or cure at low drying temperatures, at most the web dimensional integrity threshold (which may be, for example, 85°C (185℉)), the printing compositions disclosed above are suitable for webs subjected to dimensional changes, such as heat-shrinkable films. The at least one co-solvent in the above-described printing compositions is believed to have evaporation characteristics within the web dimensional integrity threshold, which, when combined with other printing components, will allow for efficient drying and adhesion of the printing components to the web. Additionally, within the web dimensional integrity threshold, the amounts of polymers, polymer dispersions, and / or polymer emulsions and / or at least one polymer solution in the above-described printing compositions are believed to be stable when added in larger quantities with the at least one co-solvent and other components in the printing compositions. The high loading of polymers, polymer solutions, or polymer dispersions in the above-described printing compositions is believed to allow for better adhesion of the printing compositions to the web or coated surface without diluting or reducing the viscosity beyond the printhead viscosity range. Furthermore, optimal drying and / or curing at such low drying temperatures allows the printing compositions to be used for variable inkjet printing with high throughput. The ability to use such printing compositions at different throughputs and temperatures makes short-run printing operations and market segmentation targets more economically feasible.
