Abstract:

In the Printing Industry, printing inks, varnishes, lacquers, moistening solutions and washing solvents (ethanol, methyl acetate, ethyl acetate, isopropanol, n-propanol, hexane, benzene, toluene, xylene, isopropyl acetate, propyl acetate, dimethyl ketone, glycols and glycol ethers) contain volatile organic compounds (VOCs) and air pollutants (HAPs). Especially solvent based inks used for flexo, gravure and screen printing, offset printing dampening solutions and cleaning solvents contain high concentration of VOC. These organic compounds evaporate during the production process or contribute to the photochemical reaction. VOCs and HAPs, together with sunlight and nitrogen oxides, cause photochemical smoke, air particles and ground level ozone emission in the atmosphere. The VOCs and heavy metals can lead to soil and even water pollution when left in landfill. The amount of solvent retained by flexo, gravure and screen-printed products is 3-4% of total ink solvent used. The solvent in the printed ink content, except for the one held by the printed material evaporates in its own environment after the printing process. Most of these solvents and organic compounds used in printing environment contain at least one carbon and hydrogen atom and have negative effects on health and environment.In this study, the environmental impacts and risks of inks and solvents used in the printing industry have been evaluated. Measures to be taken to reduce and manage these environmental effects and risks have been addressed and recommendations have been made.

Abstract:

Purpose The purpose of this study is to explain the effects of screen printing parameters on the quantity of ink deposited and the print quality in the context of printing of functional inks. Both these aspects of printing are crucial in the case of conventional and functional printing. This is because, in the case of conventional printing, the quantity of ink deposit affects the color strength while in the case of functional printing, it directly affects the resulting functionality of the ink layer. Design/methodology/approach In this work, an automatic lab-scale screen printer was used to print functional inks on a paper board substrate. The printing parameters, i.e. printing pressure and squeegee angle were altered and the resulting effects on the quantity of ink that was deposited were recorded. The quantity of ink deposit was related to its surface resistivity. In addition, the quality of the print was also assessed by examining the design registration quality. Findings The authors found that altering the squeegee angle has a significant effect on the properties of the resulting ink deposit. More importantly, the authors found that the deflection in the rubber blade squeegee was greatly dependent on the initial angle of the squeegee at the start of the printing stroke. For each set value of the squeegee angle that was considered, the actual angle during printing was recorded and used in the analysis. A printing pressure of three bars and squeegee angle of 20° resulted in the maximum weight of ink deposit with a correspondingly lowest surface resistivity. Practical implications This study is envisaged to have considerable practical implications in the rapidly growing field of functional printing of flexible substrates including, but not limited to, textiles. This is because, the study provides an insight into the effects of printing parameters on the characteristics of a functional ink deposit. Originality/value Screen printing of flexible substrates is a well-developed and arguably the most widely used printing technique, particularly for textiles. Numerous studies report on the analysis of various aspects of screen printing. However, to the best of the knowledge, the effects of printing parameters on the characteristics of functional inks, such as electrically conductive inks, have not been studied in this manner.

Abstract:

Based on the study of definition of printing production intent with JDF, and the completed study of printing process planning modeling based on polychromatic sets theory, the solution of printing process searching was proposed in this paper. First, the JDF document which includes the Product Node was parsed to acquire the “requirements of printing production in terms of client”. Second, printing order was analyzed to acquire the “requirements of printing production in terms of non-client”. At last, the printing process was calculated with the polychromatic-sets-theory based printing process search algorithm. The printing process searching prototype software was developed by Java, and a print job was analyzed to verify the solution.

Abstract:

Abstract. Gravure printing has the characteristics including thick ink layer, bright and homochromatic color, rich and sharp tone, and strong stereoscopic impression. In the packaging-printing field, gravure printing gets more and more attentions. But in the region of gravure printing process, the study on gravure printing ink transfer is not as deep as offset print. Most researches just stay in the level of qualitative analysis, but the quantitative analysis researches are still insufficient. The factors which impact gravure printing ink transfer are not only the volume of engraving ink cell, but also printing process. In this paper, gravure printing ink transfer is analyzed quantitatively from the point of views of gravure printing pressure, printing speed, scraping blade pressure and ink viscosity. The following research has been done in this paper. Firstly, electronic engraving machine is used to engrave eight different area ink cells by 45° ink cell angle and 70lpc screen line number on the same gravure roller. Secondly, gravure proofing machine is used to make proofs in different process conditions. Thirdly, density meter is used to determine density of cell ink, and balance is used to determine the weight of ink which moves from the plate onto the paper. Finally, to analyze the influence of different printing processes on gravure printing ink transfer. The research results show that gravure printing ink transfer is influenced certainly by different printing processes. Printing process has a certain influence on the gravure printing ink transfer, and the influence degree of different dot area rate of cell is different. The doctor blade pressure and ink viscosity influence greatly gravure printing ink transfer.

Abstract:

Paper based printing plate is one of printing plates used in eight mo octave or specifically offset printing machine. In the printing process, the printed plate wants to keep its shape by the pressure, the friction and tension. It needs to have good dimensional stability and good ink-water balance of coating. This paper discusses the influence of different coating formulations and coating process on the mechanical properties of paper-based printing plate. In this paper, the wet strength of paper-based printing plate of different formulations and different coating amount were tested. The study provided the theoretical basis for ink-water balance coating formulations of paper-based printing plate and the plate production.

Abstract:

Automation has become the prior need to meet up the growing trends of industries today. The biggest benefit of automation is that it saves labor. However, it is also used to save energy and materials and to improve quality, accuracy and precision. Automation has been achieved by various means including mechanical, hydraulic, pneumatic, electrical electronic and computers, usually in combination. This paper deals with the printing of days and dates on the watch indicators using an automated system. This automated system comprises of a robot (cobra i600) and PLC controlled mechanics. The conventional printing was done using pad printing method, which was controlled by manual operations. The manual operations involve (70-80%) human effort; number of indicators being printed in span of 8 hours (1500 - 2000 indicators) and it also depends on the workers efficiency.

Abstract:

Abstract The rheological properties of silver inks are analyzed, and the printing results are presented based on the inks and roll-to-roll (R2R) printing speed. The shear viscosity, shear modulus, and extensional viscosity of the inks are measured using rotational and extensional rheometers. The inks exhibit the shear thinning power law fluids because the concentration of dispersed nanoparticles in the solvent is sufficiently low, which minimizes elasticity. After the inks are printed on a flexible substrate through gravure printing, the optical images, surface profiles, and electric resistances of the printed pattern are obtained. The width and height of the printed pattern change depending on the ink viscosity, whereas the printing speed does not significantly affect the widening. The drag-out tail is reduced at high ink viscosities and fast printing speeds, thereby improving the printed pattern quality in the R2R process. Based on the results obtained, we suggest ink and printing conditions that result in high printing quality for complicated printings, such as overlay printing registration accuracy, which imposes pattern widening and drag-out tails in printed patterns.

Abstract:

Three dimensional (3D) printing as an advanced manufacturing technology is progressing to be established in the pharmaceutical industry to overcome the traditional manufacturing regime of 'one size fits for all'. Using 3D printing, it is possible to design and develop complex dosage forms that can be suitable for tuning drug release. Polymers are the key materials that are necessary for 3D printing. Among all 3D printing processes, extrusion-based (both fused deposition modeling (FDM) and pressure-assisted microsyringe (PAM)) 3D printing is well researched for pharmaceutical manufacturing. It is important to understand which polymers are suitable for extrusion-based 3D printing of pharmaceuticals and how their properties, as well as the behavior of polymer–active pharmaceutical ingredient (API) combinations, impact the printing process. Especially, understanding the rheology of the polymer and API–polymer mixtures is necessary for successful 3D printing of dosage forms or printed structures. This review has summarized a holistic materials–process perspective for polymers on extrusion-based 3D printing. The main focus herein will be both FDM and PAM 3D printing processes. It elaborates the discussion on the comparison of 3D printing with the traditional direct compression process, the necessity of rheology, and the characterization techniques required for the printed structure, drug, and excipients. The current technological challenges, regulatory aspects, and the direction toward which the technology is moving, especially for personalized pharmaceuticals and multi-drug printing, are also briefly discussed.

Full text

Abstract:

Three-dimensional (3D) printing, also called additive manufacture (AM), is a novel, automated method of printing a structure layer-by-layer directly from a 3D digital design model. Its potential ability to build complex shapes in a less costly and more sustainable manner may revolutionize the construction industry. There are three main 3D printing techniques: (a) contour crafting; (b) concrete printing, and (c) D-shape. As a disruptive technology, 3D printing creates a new market and value network, thus disturbing the established market. Building information modeling (BIM) is a comprehensive management approach encompassing the entire life cycle of the architecture and construction (A&C) process, including architectural planning, geometrical data, scheduling, material, equipment, resource and manufacturing data, and post-construction facility management. By maintaining safety and productivity in large-scale digital processes, BIM is critical to 3D printing’s success in construction. Integrating BIM and 3D printing techniques into A&C can potentially lead to an ecological architectural process that reduces waste and energy inefficiency, and prevents injuries and fatalities on construction sites, while increasing productivity and quality. This paper examines BIM-based 3D printing of sustainable buildings, which may revolutionize the construction industry and contribute to a sustainable environment

Abstract:

This study aimed to determine the role of quality control in the printing process of packaging products printed by PT XYZ. The reason why quality should be emphasized was because a good quality will encourage the business progress and decrease the defect or damage. This study used descriptive qualitative method. The data collection methods were collected through interview, literature study and direct observation by the writer. PT XYZ had set specifications and quality control procedures, but the results of printing packaging product were still unmatched with the specifications. There were 3 stages of XYZ quality control starting from quality control of incoming raw materials, quality control in the production process, and quality control of finishing. The inspections carried out during the printing process aimed to ensure that the printing results met the standards and specifications set by the company as a proof from the customer. Thus, it could reduce the risk of products that did not meet the printing quality standards which later continued to the next process and sent to the customer.

Full text

Abstract:

We considered pattern formation, i.e. viscous fingering, in the ink splitting process between an elastic flexographic printing plate and the substrate. We observed an unexpected scaling behavior of the emerging pattern length scale (i.e., finger width) as a function of printing velocity, fluid viscosity, surface tension, and plate elasticity coefficients. Scaling exponents depended on the ratio of the capillary number of the fluid flow, and the elastocapillary number defined by plate elasticity and surface tension. The exponents significantly differed from rigid printing plates, which depend on the capillary number only. A dynamic model is proposed to predict the scaling exponents. The results indicate that flexo printing corresponded to a self-regulating dynamical equilibrium of viscous, capillary, and elastic forces. We argue that these forces stabilize the process conditions in a flexo printing unit over a wide range of printing velocities, ink viscosities, and mechanical process settings.

According to the characteristics of ink feeding and printing quality control principles, a new test sheet was designed for qualifying press state and the test results were discussed in this paper. This test sheet was printed under the condition that printing ink volume for different ink zone is identical. Solid density, dot gain and print contrast of different printing ink volume were simulated on a single test sheet, and thus the optimal printing status can be determined quickly. Experiment results show that this method is accessible, economic, and rapid. The optimum solid density values can be got easily for all primary colors on a single test sheet. This method is suit for the adjustment of printing status.

Abstract:

PurposeStencil cleaning is an important operation in solder paste printing process. Frequent cleaning may interrupt printing process and increase idle time, as well as loss for performing cleaning. This paper aims to propose a method to optimize the stencil cleaning time and reduce unnecessary cleaning operations and losses.Design/methodology/approachThis paper uses a discrete-time, discrete-state homogeneous Markov chain to model the stencil printing performance degradation process, and the quality loss during the stencil printing process is estimated based on this degradation model. A stencil cleaning decision model based on renewal reward theorem is established, and the optimal cleaning time is obtained through a balance between quality loss and the loss on idle time.FindingsA stencil cleaning decision model for solder paste printing is established, and numerical simulation results show that there exists an optimal stencil cleaning time which minimizes the long-term loss.Originality/valueStencil cleaning control is very important for solder paste printing. However, there are very few studies focusing on stencil cleaning control. This research contributes to developing a model to optimize the stencil cleaning time in solder paste printing process.

Abstract:

To monitoring the ozone concentration in the atmosphere of the printing process, a compact ozone monitor was developed. The compact ozone monitor is consisting of a low pressure mercury capillary lamp and semiconductor photo detectors and one single (28cm) optical cell. The second UV-detector was introduced to improve the resolution and stability of the instrument. The ozone monitor with compact size and simple structure features good linearity, repeatability, and very good selectivity.

Abstract:

The subject of the review is methodology of the subsystem verification and printing 3 D -model online learning system mixed type. To do this, a review of analogues, technologies, stages of printing were identified. Due to the development of technology, the educational process is being transformed. Education uses blended learning, part of which is distance learning. The object of research is use of additive technologies, which can make the learning process more motivating. Thus, if in distance education there is an opportunity to develop a 3D model online, check it for fidelity, send the model to print, it optimizes the learning process. The aim is to design with IP topics that uses the additive technologies in the educational process. Methods used: IDEF- diagram describing the function of the system; authentication rules, verification of 3 D models, sending the model to print, selecting a device online, and basic screen forms. Conclusions. The development of innovative thinking in higher education students should become a priority of modern higher education, and the introduction of new elements in modern education is inevitable. And given the development of 3D printing technologies, additive technologies are the most promising for the use of visualization in online and mixed teaching.
