Utveckling av bestrykning för papper avsedda för bläckstråleskrivare

Detta examensarbete har utförts på papperstillverkaren Arjo Wiggins’ forskningscenter i Beaconsfield,England. Företaget har planer på att börja tillverka en ny papperskvalitet för bläckstråleskrivare, varförsyftet med arbetet har varit att testa och utvärdera olika sammansättningar av kemikalier som lämparsig för bestrykning av bläckstrålepapper.Ett stort antal bestrykningar har testats med varierande resultat. Det svåraste har visat sig vara attnå en tillräckligt hög grad av vattenhållfasthet. Resultaten förbättrades något då baspapperetbyttes från ett limmat och kalandrerat papper till ett olimmat, okalandrerat papper. I övrigt visade sigbindemedlen ha större påverkan på bestrykningens egenskaper än pigmenten. Utskriftskvaliteten haröverlag varit god.

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.

Vitpunktsförskjutningens påverkan på ICC-profiler vid användande av optiska vitmedel

The connection between fluorescence and color management still is a relatively unexplored area. Thefollowing composition analyses the theory that when printing on fluorescent ink jet paper using ICCprofilesa more yellow print will appear. In theory the ICC-profile compensate for blue light that fluorescefrom the paper with the complementary color, yellow. The human eye apprehands this fluorescentlight as white.When categorizing a number of ink jet qualities some tests to indicate change of color in the final printwere made. Five qualities were chosen for further analyses, each with different white point. TheTC3.5CMYK target was prined on an ink jet printer and measured with different filters for the measurementequipment, GretagMacbeth Spectrolino. U- and UV-filters were used during the testings.From the measurement data ICC-profiles were made to make it possible to watch how the profiles compensatefor the blue change of color that appeared in the data. Although a distinct change of color intoblue were discernible in the measured data there is no evident proof that this cause a final print thatis more yellow. Other conclusions and results are to be read at the end of this composition.

Konstruktion och design av två glassförpackningar i kartongkvaliteten Frövi Light

This degree project was made in cooperation with AssiDomän Frövi and Charlotte Andersson and the main objectivehas been to create to ice cream pacbges from 250 gsm Frövi Light board. The paekages are intended to be easilyresealable while decreasing in size together with the ice cream. The project also describes the food packaging labelsand symbols currently present in the European common market.Both capsules utilize a separate lid for resealing. One of the paekages (Capsuie A) is indended to be cut along withthe ice cream and thereby decrease in size. The other one (Capsuie B) uses a series of flaps for contracting and expandingwhich enab1es adjusting of the size without cutting the package up.The design for Capsuie A is created both as a series of flavours with a super-hero theme intended for children andwith a colfee flavour for a maturer audience. For Capsule B, a design was created for a sorbet.

Framtagning av ICC-profil för VTAB Backa

The following degree project deals with the production of an ICC-profile, this in the form ofproducing ICC-profiles for VTAB Backa. The company previously had their own profile butthey weren’t satisfied, so earlier this year they started using the TU standard profile, but theyalso wanted a complement to this in form of a profile created for solely their printing press.The separation settings used when creating the new profiles were based on information fromTU and their profile. Two basic profiles were created and then edited to obtain a better result.The test printings made with the edited profiles showed that the less adjustments that are made,the better. It was also discovered that the TU standard profile eliminates the highlight toneswhiles the new profiles are somewhat darker. VTAB Backa has at the end of this degree projectdesided to conduct more test printings before making their decision.

Studie till uppstartande av annonskatalog

Sten Jonsson wants to start a production of an advertising catalogue for small companies in Sweden. Acatalogue where the advertisingcost is so low that most of the companies can afford to participate. Thecompanies who will advertise should be manufacturing companies in trades of carpentry, sheet metalworkshops, forging workshops and engineering workshops.The catalogue will facilitate for the manufacturer to reach the costumer without any middleman.Without a middleman creates a possibility for an opinion about the product at the same time as theprice can be held low. A catalogue of this type would benefit the marketing of the companies at the sametime as it would generate an occasion for innovations.The possible target groups are property companies, construct companies and farmers.A market research has been carried out contained a postal interview and a phone interview. Themarket research carried out to get an understanding in what the companies think about the idea butalso to see if the companies are in interest of advertise in the catalogue. Unfortunately the marketresearch became unusable when only three of thirty companies comment the idea and two of themwanted to meet for a further visit. In relation to the market research a deeper study in market research,in which essential parts for the project, was made.A dummie has been done to show the design of the catalogue.A calculation has also been done to get an understanding in what the project would cost to start.

Kvalitetskontroll av utskrifter från Kodak Approval XP4

When using the digital halftone proofing systems, a closer print match can be achieved compared to what earlier couldbe done with the analogue proofing systems. These proofing systems possibilities to produce accurate print match canas well lead to producing bad print matches as several print related parameters can be adjusted manually in the systemby the user. Therefore, more advanced knowledge in graphic arts technology is required by the user of the system.The prepress company Colorcraft AB wishes to control that their color proofs always have the right quality. This projectwas started with the purpose to find a quality control metod for Colorcraft´s digital halftone proofing system(Kodak Approval XP4).Using a software who supports spectral measuring combined with a spectrophotometer and a control bar, a qualitycontrol system was assembled. This system detects variations that lies out of the proofing system´s natural deviation.The prerequisite for this quality control system is that the tolerances are defined with consideration taken to the proofingsystems natural deviations. Othervise the quality control system will generate unnecessecary false alarms and thereforenot be reliable.

Granskning av kvalitetssäkringsarbetet vid en ICC-profilbaserad trycksaksproduktion

To make your company change from a conventional workflow to an ICC-based workflow you need tomake investments in time and money. On the other hand you get your reward in terms of a stable andquality safe production. To choose this way of adjusting your company to new routines requires accuracyas well as a great deal of commitment. It is not only about having the right equipment. There area lot of factors that affect the quality of production.Our ambition with this report is to bring out the importance of general thinking when it comes toICC-profiling and to discuss on which basis printing profiles should be created. Quality parameters asfor example roughness and whiteness of paper are also discussed. To be able to investigate these mattersin detail we have taken a closer look at two companies, which have chosen to commit themselvesto achive better quality through color management but still feel that they have some problems withtheir workflow.One of the conclusions that are made in this report is that both companies should extend their investmentsin education of employees to become less independent of consultants, but also to increase theinterest in changes within the company. It is also stressed that an ICC-profile only can be efficient if acompany commits itself to accuracy regarding routines, control and calibration.

Omläggning av skiftgång

The digital printing market is changing faster now than before and the ability to adjust to newsituations has become more importat to a printing company. An efficient internal communicationis essential. At Elanders Digitaltryck a decision was made in august 2002 to look over the shiftworking system for the printer operators. In this paper, an investigation of the possibilities tochange the existing system to a better one was made.The project resultet in four different timetabels. The construction was based on theoretical studiesand an analysis of the current situation at the workplace. The analysis showed that a strong resistanseagainst a change of the working hours exists among the workers and that this should beconsidered before a decision is made. An analasys of the printers counters shows that they areused more efficient during shorter shift periods compared to the longer ones. A closeer look at theabcense due to sickness shows that it is relatively high but no connection between abcense andworking hours could be made.Working hours is a sensitive issue and should be treated with care. It is important that the workersare well informed and preferly involved in the development of a new timetable.

Kartläggning av plastkorkar och förslag till förbättringar för den australiensiska marknaden

The project Design analysis and proposals of plastic screw caps in Australia was performed at Högskolan Dalarna incooperation with University of Western Sydney, Australia. The Swedish company Tetra Pak, in Lund, were assigner forthe project that was performed 2006-2007. The commission was to do a survey about the packages for non-carbonateddrinks in Australia. The bottles had to be plastic, able to open in one step and with focus on the caps.The project has result in design analysis and a new proposal of a plastic screw cap for the Australian market. Sixbottles were choosen and they were all testet on 20 consumers each with a Likert-scale test. The result from the test andthe survey underlied the work with a proposal of a new design. The most important qualities for a optimal opening is:a tamper that is easy to break and also guarantee that is not been opened before, wide and soft grip, ergonomics, easyto close and that is good looking.

Ett bortglömt föräldraskap : anknytningsprocessens förutsättningar, risker och främjande insatser vid adoption

Syftet med denna systematiska litteraturstudie var att sammanställa och analysera kunskapsläget inom befintlig forskning om anknytningsprocessen mellan adoptivbarn och deras adoptivföräldrar och hur denna process kan främjas. Metod var en systematisk litteratur studie baserad på 32 artiklar. I resultatet fann författarna att en bra anknytning är en viktig bas för barns framtida utveckling samt att adoptivbarn löper större risk att drabbas av mental ohälsa jämfört med biologiska barn. En anknytningsrisk som kan drabba adoptivföräldrar är post adoption depression. Adoptivföräldrar behöver mer stöd jämförelse med andra föräldrar samt att det finns för lite stödåtgärder till adoptivföräldrar på barnhälsovården. Babymassage har visat sig vara en effektiv stödåtgärd för att stärka anknytningen mellan adoptivbarn och deras föräldrar. Motiverande samtal används inom pediatriken för att ge information till föräldrarna på ett effektivare sätt.

Förändringsförslag förABB:s godshantering : – Utvärdering av existerandeautomatiska datafångstmetoder

Examensarbetet utfördes på uppdrag av ABB i Ludvika. ABB vill öka effektiviseringen förhanteringen av inkommande gods. Detta för att det mesta sker manuellt i dagens läge och det tarmycket tid och kan resultera i felkällor.Arbetet har två syften. Det första syftet är att förändra del av verksamheten, genom att kommamed ett förändringsförslag när det gäller godshanteringen. Det andra syftet är att jämförastreckkoder och RFID för att se vilket alternativ som passar bäst.För att få fram ett förändringsförslag har vi jobbat med FA/SIM-metoden.Vi har tagit fram ett antal förändringsförslag nedan följer ett urval av dessa:• Ställa krav på leverantörerna att de skall använda streckkoder med rätt standard Code128.• Utforma tydliga och enkla kravspecifikationer för att enklare kunna ta till sig.• Förbättra nuvarande kundrelationer. Genomför en uppföljning med jämna mellanrum föratt se hur kundrelationerna sköts.

Unga kvinnors upplevelse av beslutsprocessen vid abort

Syfte: Att belysa den unga kvinnans upplevelse av beslutsprocessen vid valet av abort, som underlag för helhetsförståelse vid omvårdnaden av denna. Metod: Litteraturstudie som redovisar resultat från artiklar med kvalitativ- och kvantitativ ansats samt två systematiska litteraturstudier. Datainsamling skedde genom databaserna ElinDalarna, Academic Search Elite (EBSCO) och SveMed+. Sökord som använts är - abortion, psychological aspects, decision-making, experience och omvårdnad. Huvudresultat: I beslutsprocessen präglades kvinnorna av ambivalens. Känslor vid oönskad graviditet skiljde sig inte mycket mellan olika kvinnor. Även kvinnor som var säkra i sitt beslut upplevde ambivalens. Abort som en lösning på oönskad graviditet hade sitt pris hur beslutsam kvinnan var. Ett abortbeslut var för många kvinnor en smärtsam nödvändighet och många kvinnor upplevde ångest vid abortbeslutet. Känslor och erfarenhet som kvinnor upplevde i beslutsprocessen och vid abort påverkde kvinnornas känsloliv resten av deras liv. Kvinnors konsultationsmönster, angående sin oönskade graviditet, är annorluna än vid andra stora händelser i livet. Kvinnor sökte ofta stöd i sitt beslutsfattande. Det var viktigt att sjuksköterskan, i mötet med den abortsökande kvinna, förhåller sig neutral i tal samt använda öppna frågor. Slutsats: Under förespegling att kvinnan har ett fritt val gör hon sitt val av abort. Detta val innehåller allehanda komplexa känslor och paradoxer. Det är viktigt med medvetenhet om detta, bland sjuksköterskor, för att ge adekvat och neutral omvårdnad.

Anhörigvårdarnas upplevelser i hemmet vid livets slutskede, med hjälp av palliativa teamet

Idag ökar den palliativa omvårdnaden i hemmet. För att den sjuke ofta har en önskan om att få dö hemma. Det ställer krav på anhörigvårdarna som är dem som kommer att bli dem primära vårdarna. Syftet med studien var att undersöka anhörigvårdarnas upplevelser av att vårda hemma, i livets slutskede, med hjälp av det palliativa teamet. Studien genomfördes som en systematisk litteraturstudie. Genom litteraturstudien fick man fram de positiva och negativa upplevelserna från anhörigvårdarna som vårdat den sjuke i hemmet. Studien visade att anhörigvårdarna skulle välja att vårda den sjuke i hemmet igen med hjälp av det palliativa teamet. Detta trots att flera negativa upplevelser kom fram. Anhörigvårdarna ville vara mer delaktiga i omvårdnadsarbetet och detta gjorde att anhörigvårdarna upplevde en större tillfredställelse av själv, genom att kunna ge något tillbaka till den sjuke. Anhörigvårdarna önskade mer stöd från vårdpersonalen eftersom de ansåg sig ha bristande kompetens om medicinteknik, kroppens hälsa, sjukdomen, dess symptom, behandling, och prognos etc.
