Färgperception och grafisk profilering av Hedemora Assistansservie

An inquiring study of literature has been conducted, about the human colour perception (theimpression of colours). The colour has been examined, both as conscious and subconscious signal,and reasons for it’s influence have been exammed.The practical parts of the degree project have been carried out in active collaboration with thecustomer, The Association Hedemora Assistansservice (HASS), which offers handicapped persons astimulating spare time by personal assistance. A graphical profile-programme and an informationfolderhave been produced, easy received by both handicapped (with defective vision) and normallysighted persons. The graphical profile-programme was made in collaboration with the customer.Concerning the information-folder HASS took the main responsibility for the choice of photographswhile layout, text writing, colour-reproduction, original-production and connecting printing workswere made independently. The customer has shown engagement and interest and had a lot of opinionsabout the degree project, of which have been paid attention.

Utvärdering av digitala provtryckssystem

Six different Digital Proofing Systems from three different techniques have been evaluated as totechnique, printing quality, economy and usability. Digital proof from two paper qualities, coatedand uncoated, has been compared with references printed in offset, to see how good they match eachother. Only two Proofing Systems manage to print on reference paper. The other Proofing Systemsuse special paper for digital proof.Measurements and visuell judgement show that the Digital Proofing Systems visualise referencepictures with quite good quality. Proof optimised for coated paper visualise the colours with goodresult. Proof optimised for uncoated paper shows higher quality than the references, which depends onthe surface of the proofing paper. Comparison between reference paper and proofing paper has takenplace as to differences in colour and paper quality.The Digital Proofing Systems are fully automatic, which demand a quite comprised education forcorrect handling. The purchase price and printing costs vary considerably between the ProofingSystems.

Färgstyrning av kontorsutrustning

Color management has become more common now than ever in the graphic trade. Calibration andcharcterization are words that are mentioned very often when it comes to controlling colors andwhen you want a printed picture to look the same as an original photograph. The problem is thatthere are not so many people that has the knowlegde about this subject. Even if a printer supportscolor management it is not sure that the result is going to be satisfied and that a printed picture isgoing to look the same as the original.The printers which were used were Hp DeskJet 970 Cxi, Xerox Docu Color 12 and AgfaChromapress 50i. The theory of color, colour management and the equipment which were usedare described in the first stage. The second stage describes calibration and characterization ofmonitors, scanners and printers. Finally the result of created ICC-profiles is set by visual comparisionof a photographs original colours and a scanned and printed photograph.The results of calibration and characterization were varying a lot. Agfa Chromapress 50i was theonly printer which could produce a succesful calibration. Agfa Chromapress 50i and XeroxDocuColor 12 gave the best results when comparing original photographs with printed pictures ifthey were separated with ICC-profiles. ICC-profiles created for Hp DeskJet 970 Cxi achievedundesirable effects. This was the only printer that gave a bad result both with and without ICCprofiles.The reason for this miserable result can depend on the printers unability to fully supportcolor management.

Redesign av personaltidningen Energitrycket samt anpassning för kopiering och publicering för webben

This degree project has been carried out on the commission of AB Borlänge Energi. The purpose of thisproject was to redesign the magazine Energitrycket. The magazine should inform about the current eventsat the company. The work consisted of redesign of the existing magazine and adjustment to copying andpublishing on the web.This project also contains a research about how paper and colour affect the print results. It shows thatthe maximum contrast and sharp image reproduction is best achieved on woodfree, coated, calenderedpaper with high whiteness. An uncoated, light yellow paper is however to recommend for a printed matterswith a lot of text.It also shows that every production unit reproduces colours differently. To get a good colour reproductionand a good communication between these units, they must be calibrated, and well-functioningICC-profiles must be created.

Broschyr om avändarprofiler

The project group is participating in a measuring project that is a cooperation between CIT EnergyManagement AB, the Measuring unit of Chalmers and College of Dalarna.The results from the measurementswill be put together and presented in a brochure.When designing the brochure a great deal of planning has been made how to attract the targetgroup.To make the contents of the brochure more attractive, which mainly will contain text, a lot of imageswith a symbolic substance have been used. To keep the brochure together it has been divided into fivechapters that each has been given one specific colour. The colours are consistent on initials, headlinesand images.At the moment the results of the measurements are not yet ready and the text for the brochure is notpossible to complete now. This project is expected to finish in the fall when all the measurements havebeen compiled.

Kvalitetssäkring av Clas Ohlson AB´s grafiska produktionsflöde

The question formulation in the essay brought up whether Clas Ohlson works today with their graphical productionflow and if that way of working leads to a desirable result in press. After a dialogue with Clas Ohlson it emerged thatthey had certain problems with the material that came out of the printing presses. Certain colours were not reproducedaccording to the stated values that had been developed. In March -08 an analysis of the graphical production flowspresent situation were done at Clas Ohlsons in order to find out how they worked with their production of print materials.In the analysis, their way to work with color spaces, displays, ICC-profiles, PDF-exports, pictures and printerswere examined. Occasional interviews were also implemented with responsible personnel about how they worked withdifferent aspects.Deficiencies were found on almost all examined parts in their graphical production flow. Wrong colorspaces andCMYK-profiles was used in big extent, the displays where uncalibrated or incorrectly calibrated, wrong PDF-presetswas used frequently and it also showed that six different suppliers for their printing materials were used. The solutionsthat were relevant for the problems and defects were later on presented as proposals on measures.

Grafisk profilering som en del avvarumärkesarbetet

A strong brand can help a company to be easier to recognize and be remembered by their customers. Part of branding is to create a visual appearance which is called a graphic profile and contains information on for instance a logo, colours or typography.The objective of this thesis was to create a graphic profile for Stjørdal Tannhelsesenter that could serve as a base for a brand work in the future. It was important to analyze how the clinic wants to be perceived and how it is perceived today. The methods used to carry out this study were questionnaires, researches and a focus group.The work resulted in the generation of a graphic profile that included a new logo, colours, decorative elements, fonts, templates for stationery, business card / badge, imagery, and examples of some publications.According to the test which was made to examine the results of the project showed that I was successful and that the new design meets all the requests from the previous questionnaires.

Evaluation of Red Colour Segmentation Algorithms in Traffic Signs Detection

Colour segmentation is the most commonly used method in road signs detection. Road sign contains several basic colours such as red, yellow, blue and white which depends on countries.The objective of this thesis is to do an evaluation of the four colour segmentation algorithms. Dynamic Threshold Algorithm, A Modification of de la Escalera’s Algorithm, the Fuzzy Colour Segmentation Algorithm and Shadow and Highlight Invariant Algorithm. The processing time and segmentation success rate as criteria are used to compare the performance of the four algorithms. And red colour is selected as the target colour to complete the comparison. All the testing images are selected from the Traffic Signs Database of Dalarna University [1] randomly according to the category. These road sign images are taken from a digital camera mounted in a moving car in Sweden.Experiments show that the Fuzzy Colour Segmentation Algorithm and Shadow and Highlight Invariant Algorithm are more accurate and stable to detect red colour of road signs. And the method could also be used in other colours analysis research. The yellow colour which is chosen to evaluate the performance of the four algorithms can reference Master Thesis of Yumei Liu.

Färg och missfärgning hos sågad björk : - Variation samt effekter av avverkningstidpunkt, lagring av timmer och torkning av sågad vara

Variation i björkvirkets färg beror på art, läge i träd, ursprung och lagringstid. Vårtbjörk har en mörkare färg än glasbjörk, men livligare struktur och glans. Timmer hugget under tillväxtsäsongen bör sågas färskt eller lagras högst en månad. Vid brädgårdstorkning är god luftcirkulation och skydd för väta och direkt solljus väsentligt. Strövirkets färskhet är av stor betydelse för att undvika fuktfärgning av virket.Variation in birch colours depend on species, position in tree, origin and the storage period. White birch is darker than hairy birch but with a lively structure and shine. During vegetation period timber storage exceeding one month should be avoided. Air circulation, protection from rain and direct sunlight are essential for yard drying. Freshness of stickers used for stacking is important to avoid water marks on wood surface.

Printing colour hard proofs using EFI Colorproof XF v. 3.1 and Photoshop CS3, and production substrates.

EFI Colorproof XF was found to be more convenient from a user’s aspect, and had features which are covered in the ISO 12647-7 standard (e.g. the ability to simulate screening and print margin information), which Photoshop CS3 lacked. None of the proofing systems distinguished itself in a clear way from the other; sometimes, on certain substrates, Photoshop CS3 produced most accurate colours, sometimes EFI Colorproof XF did. Further investigations need to be carried out to tell more exactly which system produce most accurate colours. Only 6 out of 34 simulation-combinations had colours within the tolerances in the standard. The result also shows that the production substrates should not be used as proofing substrates. Instead the proofing papers especially made for ink jet should be used to obtain more colour-accurate prints.

O suicídio em Freud

Este trabalho é um estudo teórico sobre o suicídio em uma perspectiva psicanalítica. O que se pretendeu foi elaborar uma visão compreensiva das motivações inconscientes presentes nos processos autodestrutivos através da retomada das observações que a este respeito estão contidas na obra de Sigmund Freud, correlacionando-as com uma ordenação de suas ideias seu pensamento em termos do desenvolvimento de Inicialmente, Freud faz apenas algumas observações esparsas sobre o suicídio, e suas contribuições posteriores repousam basicamente sobre a concepção de que os impulsos autodestrutivos revelam o sentimento de culpabilidade e a necessidade de autopunição decorrente do ódio inconsciente dirigido a pessoas queridas e do desejo, também inconsciente, de que elas morram. Com a introdução dos conceitos de narcisismo, identificação primária e ideal do ego, Freud amplia seus recursos teóricos identificando a melancolia com a autodestruição. A seguir, investiga-se o aparecimento do conceito de pulsão de morte e as modificações que este conceito acarretou na teoria do suicídio. Examina-se, ainda, a compulsão à repetição, a nova concepção de pulsão como expressão da natureza conservadora dos seres vivos, a fusão pulsional e o problema econômico do masoquismo. A extrema complexidade do fenômeno nos faz concluir que, apesar das contribuições metapsicológicas que nos permitem, à luz da psicanálise, compreender a natureza inconsciente da autodestruição não se pode prescindir, no estudo de casos individuais, de uma perspectiva que leve em conta a singularidade das motivações que contribuem para a tessitura múltipla da rede de fatores que impulsionam a busca da própria morte. A história individual, o contexto sócio-cultural, e a visão que tem do suicídio a sociedade, contribuem para a trama singular, específica e acessível à análise dos atos destrutivos.

Campo e contracampo : o encontro com o outro no filme Lavoura Arcaica

This dissertation aims to comprehend how we meet with the other at cinema. For this, it receives the doubt, the uncertainty, the way that the human being is unfinished as stance of observation. It takes into consideration the multiples social vectors, historical, subjective, temporal and cultural which constitute these phenomena. The cinema is used as a cognitive resource in order to incorporate the poetic and the imaginary, making possible not forgetting gestures and knowledge that hatch from sounds, colours, remembrances, images, words, social exchanges, cognitive reciprocity that allow us to think about the culture, the society and the communication. For this, it has as theoretical prerequisites ideas of double (myselfthe other) and effective participation (projection-identification) developed by Edgar Morin, as well as the idea of communication as possibility/impossibility of constructions of bonds with the other through the body, our primary media, concepts developed by Harry Pross and Norval Baitello Jr. The chosen film to analysis is Lavoura Arcaica, it is an emblematic movie in the discussion of the human condition and in the relationship between the man and its body, its desires, with its nature/culture ambivalence. About this film are made reflections about the process of activation of the double (myself-the other) in the searching for the other through cinematographically elements of construction, as: montage, direction, screenplay, actors, scenography, costumes and soundtrack. In conclusion, the cinema, when it allows the effective participation and provides t e experiment of the double, becomes a gateway line in the path to development of the alterity

Increase in severity of molar-incisor hypomineralization and its relationship with the colour of enamel opacity: a prospective cohort study

Background. Predicting risk of posteruptive enamel breakdown (PEB) of molar-incisor hypomineralization (MIH) opacity is a difficult but important clinical task. Therefore, there is a need to evaluate these aspects through longitudinal studies.Objective. The aim of this longitudinal study was to analyse the relationship between colours of MIH opacity of children aged 6-12 (baseline) and other clinical and demographic variables involved in the increase in severity of MIH.Materials and methods. A blinded prospective 18-month follow-up was conducted with 147 individuals presenting mild MIH. Tooth-based incidence of increase in severity of MIH (PEB or atypical restorations) was used as dependent measurement. Enamel opacities were recorded according to colour shades of white, yellow and brown, allowing assessment of susceptibility to structural loss over time, according to colour of MIH opacity. Poisson regression models were used to adjust the results for demographic and clinical variables.Results. Brown and yellow MIH opacities were at higher risk for PEB and atypical restorations than those of white ones, even after adjustment for clinical and demographic variables.Conclusion. Teeth presenting mild MIH severity associated with yellow and brown enamel opacities were at high risk for increase in severity of MIH than lighter ones. This result could help clinicians determine a risk-based treatment for children with MIH.
