The FMCG sector (Fast Moving Consumer Goods) is one of the largest industries in the world wherein the brands are reliant on the customer attraction and product sales worldwide. It is important for brands to maintain the quality and color consistency of these products. FMCG labels printed with Spot colors by Flexography process is not cost-effective due to higher job changeover times and wastage. The most effective way of ensuring spot color reproduction is implementing Expanded Color Gamut (ECG) printing by using a fixed set of colors with four process colors namely Cyan, Magenta, Yellow, Black (CMYK) along with three colors Orange, Green and Violet (OGV). These seven colors provide eye-catching graphics and a larger gamut so as to reproduce maximum number of Pantone® colors. The evaluation of spot color reproduction was carried on a Nilpeter FB-430 Narrow Web Flexo press that included runs viz. Initial, Optimization, Fingerprinting, Characterization and Validation on Polypropylene substrate with UV based inks. The runs were carried as per Idealliance® specifications. The aims and tolerance as per ISO 12647-2 with CRPC 6 GRACoL 2013 for CMYK while ISO 20654 Spot Color Tonal Value (SCTV), Chroma and Hue for OGV were achieved. The customized Characterization Test Chart with 2016 patches for CMYKOGV for profile generation and Verification Test Chart with 799 patches of Pantone® Solid Coated from the Digital Library was created in CGS Oris XGamut. These Test Charts were measured using X-Rite EyeOne iO automated device. The magnitude of color match for Spot Colors by expanded gamut printing was verified on a narrow web flexography press. The gamut analysis between CRPC 6 and CMYKOGV showed that from the geometric region of Pantone® Colors Inside CMYKOGV Gamut and Outside CRPC6 Gamut, 85% of the Pantone colors were reproduced below Delta E 2.5.

The main focus of this paper is to examine the relationship between CVD risk factors and socioeconomic variables in Jammu division of Jammu and Kashmir. Cardiovascular disease (CVD) related deaths is not only the prime cause of mortality in the world, it has also continued to increase in the low and middle income countries. The study area was divided into ten districts (administrative units) in GIS environment. linear regression, binary logistic regression model, Kendal’s ranking coefficient method were employed to show the incidence, spatial variation and impact of different socioeconomic variables on CVD. The results reveals that the incidence of CVD has increased by 7.31 percent from 2008 to 2016. Samba district was having maximum change of incidence (33.24 percent), however, negative change in incidence rate was found in Udhampur district (-2.41 percent). Consumption of tobacco and alcohol are significant related to cardiovascular diseases.

Besides text and images, contemporary e-books can include multimedia, interactivity, pronunciation information and text-to-speech ready content. The current electronic publication standard (EPUB 3) provides all the technical solutions necessary for designing and displaying highly functional and content rich e-books, but the implementation is impaired by the e-reader industry, publishers and distributors. Local and global book digitization has been an ongoing process for years, encompassing publications ranging from classical literature to current technical textbooks. Textual expression of knowledge is a remnant of the past but it is still dominant today, even though interactivity and video content are known to significantly enhance the learning process. However, multimedia and interactive content for e-books is not produced because it requires time, technical knowledge and specific tools. Within the current publishing system, authors are expected to produce and design all the content for books on their own, but because of the extreme content diversity, it is unrealistic to expect that they really possess such knowledge and skills. Better collaboration among authors, publishers, distributors, the professional community and the related industry is necessary for knowledge digitization to function.

The task of packaging Packaging can be briefly defined as a science, method and technology for product preservation. The function of packaging is to protect the product that is packed in it and to protect the environment from the content inside the packaging. As a result, the products can be gaseous, liquid or solid.[1–3] The packaging must be suitable for use, i.e. handling, transport and distribution. It should inform the potential and the actual buyer and it should “sell the product”. [4,5] An important part of the packaging design is the material from which it will be made. The basic conditions that packaging must meet are the following: strength on material pressure, elasticity, plasticity, stiffness and resistance to strain, toughness, mechanical endurance and printing.[4] Packaging must protect the content and be protected itself from oxidation, moisture, odor, chemical agents and microbes. To meet these requirements, polymer materials and nanotechnology are now being used.[5,6] Packaging can also be made according to the materials, purpose in traffic, durability and function.[6–8] Classification according to materials: wood, paper, cardboard, fabric, clay, glass, metal, polymers, multilayer materials. Classification according to the traffic purpose: sales or primary, group or secondary, transport or tertiary. Classification according to durability: return, non-refundable (onetime). Classification according to function: warehouse transport, sales, use.[9,10] PACKAGING THROUGH TIME

The growth of three-dimensional visualizations and information is increasing over time, and in addition to that, technology is offering new methods, i.e. models and ways of meeting the needs of visual communication. When using the rotating linear screen, for the best results, it is necessary to be familiar with the real performance of the device. The parameters tested on forty examinees are distance, the angle of view and the impact of the background colour. The purpose was to define the optimal parameters for the device to provide visual information. The conducted test has shown that the devices have a smaller view angle than stated and that the distance needs to be greater because of low resolution and low pixel density on the screen surface, which results in small unilluminated gaps that create unwanted lines during the projection. The effect that the background has on the 3D simulation of the hologram has also been tested and it was determined that the black background in comparison to the white one is much better, as the contrast is more pronounced.

Labels and flexible packaging on the market today take a very important role. The possibility of printing on polymeric materials of flexible packaging is diverse from OPP (Oriented Polypropylene), PVC (Polyvinyl Chloride), OPS (Oriented Polystyrene), PET (Polyethylene Terephthalate) material and all types of self-adhesive paper and foil. Special highlight are the "Shrink Sleeve" labels that meet the most demanding market challenges. Its capabilities are great, and laminated materials for packaging purposes are, for their function, both as protection and as packaging. Coefficient of friction is the value that serves to meet the standard of how the flexible packaging material will glide and move on the packaging machine. This research is focused on the optimum quality of the packaging production process to meet all the preconditions for implementation of the semifinished product packaging and to avoid difficulties and possible stoppages on the packaging machine itself.

Most of the information published through graphic media is designed for people with normal eyesight. There are 285 million people with visual impairment. This number indicates a need for adaptation of the printed media targeted towards this population. World Institute for visually impaired people recommended guidelines for the design of graphic media customized for people with partial blindness. Most of the previous research related to this topic is mostly based on guidelines and characteristics of English and French language in order to enhance legibility of the text for people with low vision. This paper is trying to access the level of legibility of the text for Croatian readers with low vision by analysing parameters such as typeface and letter size, the size of punctuation marks, highlighting style, letter colour and background colour in order to suggest practical guidelines for text design within graphic medias intended for this group of readers. Seven participants from The Zagreb Association for the blind were involved in this study with remaining vision of 2-5% along with additional eye defects. According to the collected results it is shown that the relation between letter colour and background colour, or better yet contrast has the strongest influence on legibility for people with low vision. Letter size has a weaker impact and the least impact has the type of the font. The best way of highlighting text is using bold style. The magnification of punctuation marks does not improve legibility. Guidelines for designing printed media on Croatian language for people with low vision can be useful in order to enhance their ability to get information in a same way as other members of society.

In this paper, tactile tiles for teaching Braille alphabet were created using three different 3D printing techniques. Aim of this work, based on research with visually impaired individuals, is to provide educators with a new and better way of teaching the Braille alphabet with a complete 3D printed set of alphabet tiles. Recent developments in 3D printing technology enable researchers to experiment with new approaches towards the creation of new tools for teaching the Braille alphabet. It is important to examine the Braille lettering standards, capabilities of 3D printers and, in cooperation with experts who work with the visually impaired, discuss the design and functionality of the created tiles. In this research, a set of 3D printed tiles has been created, each divided into three main parts. The first part of the tile shows a basic Braille letter. This is followed by a corresponding embossed model of an object that correlates to the first letter of the word. The third section consists of the entire word corresponding to the embossed model at the bottom of the tile in Braille writing. Tiles are standardized by size and part position for corresponding letters of the alphabet and words describing the embossed model. These tiles are intended to serve as a supplemental educational tool that relies on the sense of touch as a way for the visually impaired individuals to more easily connect their own perception of familiar objects from their surroundings to words and letters. Several iterations of tiles have been printed with multiple 3D printers, with the purpose of determining optimal settings required for producing the best possible product prototype.

This paper presents the innovative possibilities of graphic technology for use in visual scenic activities. The individual values of costumes and scenography in the ultraviolet, visible and infrared spectrum are reproduced with new graphic technologies. Each element of the costumes becomes visible when illuminated with different values of wavelengths of light observed through modified cameras. With the addition of black light in the lighting design, the viewer sees only the ultraviolet element. In the absence of black light the costumes reveal only the design created in the area visible to the bare eye. The set-design elements created in infrared values, invisible to the bare eye are shown with a projection, simultaneously. The presented technique represents a new means of expression in all forms of visual art.

The set-design elements created in infrared values, invisible to the bare eye are shown with a projection, simultaneously. \u0000The presented technique represents a new means of expression in all forms of visual art.","PeriodicalId":53261,"journal":{"name":"Acta Graphica","volume":"28 1","pages":"123-127"},"PeriodicalIF":0.0,"publicationDate":"2018-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42861897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the adhesion and interactions between thermochromic offset ink and different papers as well their role in papers and prints biodegradation. Obtained results show that biodegradation of prints depends upon the adhesion, i.e. lower adhesion will result in reduction of biodegradation rate, while the strong adhesion will result in better paper degradation. Reactions between paper and thermochromic ink will form different prints properties due to different affinity of paper for ink while interactions between them will affect the prints biodegradation. When the ink is applied on paper, the polar interactions of paper will react with polar interactions of ink. Smaller amount of polar components of paper will give a print with polar character.
