Analysis of Printing Substrate, Ink Age and Number of IR Drying Influence on Electrical Resistance of Conductive Inks

As a result of availability of new technologies, functional printing as a segment has become one of the most interesting directions of research and development in graphic technology. Conductive inks are not a novelty and they already have broad possibilities in production of everyday products. There is still a big market for the broadening of their use, as well as a possibility of further enhancing their properties. This paper analyzes the influence of printing substrate, age of ink and the number of IR drying on the electrical resistance of the conductive inks. In the paper, subject of analysis was the change of electrical resistance in the line that was 9 cm long and 10 typographic points wide. The semi-automated screen-printing machine was used for printing. Three types of printing substrates were used; uncoated, coated and recycled paper. Two types of inks were used; newly opened ink and ink that was out of date for half year. After the printing, prints were dried using the IR dryer. Prints were dried once, and then additional three times. After the first and last drying, multimeter was used to measure electrical resistance of the lines. Analysis of the data shows that the older ink produces prints with higher electrical resistance. There are also notable differences in the electrical resistance based on the printing substrate

ECOLOGICAL SYMBOLS IN GREEN COMMUNICATION FUNCTION ON PACKAGING

Ambalaža je prvo što privlači i zadržava potrošačevu pažnju, pa je stoga neverbalna komunikacija putem ekoloških simbola od izuzetnog je značaja. Stoga je zelena komunikacija usmjerena na promociju ekološkog proizvoda, kao i ekološki prihvatljive ambalaže koja u svim fazama svojeg života ne utječe štetno na okoliš, te potiče ekološko ponašanje potrošača. Kako bi se utvrdila povezanost poznavanja ekoloških simbola na ambalaži, njihovog utjecaja na kupnju i postkupovnog ponašanje potrošača u smislu recikliranja ambalaže, proveli smo znanstveno istraživanje. Odgovore ispitanika prikupljali smo putem online anketnog upitnika sačinjenog od dva dijela, u prvom dijelu su bili opći podaci o ispitanicima, a u drugom dijelu njihovi stavovi o istraživanoj problematici. Nakon statističke obrade dobivenih rezultata zaključili smo da većina ispitanika poznaje ekološke oznake na ambalaži, te da na njih obraća pažnju u procesu kupnje što upućuje na uspješnost zelene komunikacije. Ispitanici preferiraju ekološki prihvatljivu ambalažu koju ne smatraju manje atraktivnom od neekološke ambalaže, te istu u posljednjih 5 godina sve više recikliraju. Rezultati ovog istraživanju otvaraju dobre su smjernice pri vizualnom oblikovanju ambalaže i kreiranju neverbalnih zelenih komunikacijskih poruka.Packaging is the first to attract and retain the consumer\u27s attention, so non-verbal communication through ecological symbols is of utmost importance. Green communication, therefore, is aimed at the promotion of ecological products as well as ecologically acceptable packaging that does not adversely affect the environment at all stages of their life, and promotes ecological behavior of consumers. In order to establish the correlation between the knowledge of environmental symbols on packaging, their impact on purchasing and consumer behavior in terms of packaging recycling, we conducted a scientific research. Respondents\u27 responses we were collected through an on-line questionnaire consisting of two parts, the first part being general data on respondents, and in the second part their views on the investigated issue. After statistical analysis of the obtained results, we have concluded that the majority of respondents know the ecological labels on the packaging and that they pay attention to the purchasing process, which indicates the success of green communication. Respondents prefer environmentally friendly packaging they do not consider less attractive than non-toxic packaging, and they have been recycled for the last 5 years. The results of this research open good guidelines in the visual design of packaging and the creation of non-verbal green communication messages

Povijesni razvoj pisma

Predmet ovog diplomskog rada je slojevita i složena povijest pisma kao najvažnijeg komunikacijskog medija. Da nema pisma, kultura u obliku u kojemu je mi poznajemo ne bi postojala ili bi bila toliko neprepoznatljiva, a pravo, religija, trgovina, pjesništvo, filozofija, povijest i mnoge druge ljudske djelatnosti bile bi doduše moguće, ali neizmjerno ograničene u usporedbi sa svjetovima što ih otvara upotreba pisma. Pismo se razvijalo od piktograma i ideograma do fonetskog pisma i na kraju alfabeta, najprilagodljivijeg i najkorisnijeg načina pisanja koji je ikada izrađen. Na osnovu tog razvoja izveden je zaključak o tradicionalnom, informacijskom i komunikacijskom razvoju pisma i njegovom doprinosu čovječanstvu

Optimizacija procesa tiska na načelima Six Sigma = Optimization of the printing process on the principles of Six Sigma

Six Sigma kao sveobuhvatna metodologija za unaprjeđenje kvalitete započela je svoj nagli razvoj 80-tih godina 20. stoljeća u Motoroli, a danas se uspješno primjenjuje u procesima poboljšavanja velikih poslovnih sustava. Primjena Six Sigma metodologije rezultira visokom razinom sukladnosti, povećanom sposobnošću procesa, smanjenim troškovima i povećanom profitabilnošću kao temeljnim odlikama konkurentnosti. Analizom teorije, kao i dosadašnjih istraživanja uočen je nedostatak modela za potpuno upravljanje kvalitetom koji bi rezultirao optimizacijom procesa tiska. S obzirom da se Six Sigma metodologija pokazala prikladnom za optimizaciju u različitim proizvodnim industrijama, cilj ovog rada bio je napraviti model za optimizaciju procesa tiska na načelima Six Sigme. Takav model omogućava kontinuirano ostvarivanje stabilnih i predvidivih rezultata, odnosno smanjuje mogućnost varijabilnosti procesa. Oblikovanje novog modela baziranog na načelima Six Sigme zasnivalo se na detekciji i grupiranju mogućih točaka u procesu tiska koje bi dovele do varijacija u proizvodnji, a time i na samom proizvodu. S obzirom da je Six Sigma statistička mjera funkcioniranja procesa, te joj je osnovna namjera mjerenje varijabilnosti procesa, praćenje promjena razine sigme poslužilo je kao indikator promjena u procesu. Stoga je bilo potrebno definirati moguće granice varijabilnosti u procesu, pa su se u tu svrhu odredili funkcionalni zahtjevi proizvoda. Za svaki funkcionalni zahtjev proizvoda definirale su se metode kontrole i kritične karakteristike proizvoda koje su se analizirale, te grupirale prema kategorijama uzroka. Također se definirao maksimalan opseg svake karakteristike određen donjom i gornjom granicom tolerancije, te točke kritične za kvalitetu. U prvom dijelu istraživanja analiziran je nulti proces da se utvrdi da li je proces u stanju statističke kontrole procesa, da li je normalno distribuiran i ispravno centriran u odnosu na definiranu i praćenu karakteristiku proizvoda. U analizi nultog procesa akcent je bio na izračunu trenutne razine sigme i preliminarne sposobnosti procesa. U drugom dijelu istraživanja definirani su funkcionalni zahtjevi proizvoda, kritične karakteristike proizvoda i točke kritične za kvalitetu, te je provedena skupna analiza 27 parcijalnih procesa. Na kraju je na osnovu dobivenih rezultata istraživanja napravljeno modeliranje i testiranje novog optimizacijskog modela. Okosnica izrade modela bilo je generiranje optimizacijske jednadžbe gdje je uzeto generiranje funkcije u ovisnosti o tri varijable. Odabrana metoda najmanjih kvadrata se uspostavila kao dobra aproksimacija krivulje s odstupanjem manjim od 1%

UTJECAJ PROMJENJIVE POSLOVNE OKOLINE NA VRSTE RIZIKA

The changes in business environment resulted in new types of risks in the electric power companies. Therefore, it is very important for electric power companies to identify risks and to find correlations between them on a regular basis, so as to protect and increase the company value. This paper proposes the following three hypothesises: H1 There are changes in types of risks in electric power companies in the course of the last decade. H2 There is a correlation between the intensity of market competition and the impact of the present types of risks. H3 There is a correlation between present types of risks in electric power companies. All theses were proven to be true. Moreover, we identified the most critical risks that the electric power companies are facing today, and have compared them with those of a decade ago. We explored the intensity of market competition and examined a relationship with different types of risks.Promjene u poslovnom okruženju uvele su novi tip rizika u poduzeća elektroprivrede. Zbog toga je za poduzeća elektroprivrede vrlo važno identificirati rizike i naći korelaciju među njima, te to činiti redovito kako bi se zaštitile i povećale vrijednost kompanije. U ovom se radu predlažu sljedeće tri hipoteze: H1 Postoje promjene u tipu rizika u poduzećima elektroprivrede tijekom zadnjih 10 godina. H2 Postoji korelacija između intenziteta tržišne konkurencije i utjecaja prisutnih/postojećih tipova rizika. H3 Postoji korelacija između postojećih tipova rizika u poduzećima elektroprivrede. Sve teze dokazane su kao istinite. Nadalje, identificirani su najkritičniji tipovi rizika danas s kojima se suočavaju poduzeća elektroprivrede, te uspoređeni s onima od prije deset godina. Istražen je intenzitet tržišne konkurencije, te ispitana povezanost s različitim tipovima rizika

Fuzzy Logic-Based Evaluation Model of Handwritten Font Sizes Readability on Extra Small Devices

Handwritten fonts are appealing to designers, but their application in web design can cause a readability problems. Different handwritten letter cuts in different font sizes are not equally readable on all screen types. The problem often occurs on extra small devices such as mobile phones. Therefore, it is necessary to choose the combination of the font type and appropriate font size that will ensure responsiveness and be readable on different devices, especially the small ones. For this purpose, a study of readability of monoline handwritten font in seven letter cuts (thin, ultra-light, light, regular, semi-bold, bold, and ultra-bold) in several font sizes was conducted. Variable font was used because it contains all style versions of one typeface family, as opposed to standard font families that use different files for each style version. Also, variable font is suitable for use on web because one file with all the necessary typeface styles is significantly smaller in size than classic families with multiple files which shortens the font loading time. Furthermore, model of readability evaluation using the fuzzy logic based postprocessing method for segmentation values related to evaluation criteria is proposed. Prototype of a variable handwritten fonts are tested in responsive web environment, using CSS technology. The results show that handwritten font size readability evaluation has measurable output because the score combine various numeral factors affecting the readability of particular font size in several letter cuts.  Using of proposed model in short time can show readability level of some font type in some font size on a new responsive web suitable for different screen sizes, including extra small devices
