Redesign av personaltidningen Energitrycket samt anpassning för kopiering och publicering för webbenPlivac, Dzenana January 2004 (has links)
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.

En förstudie till kvalitetsutveckling på GD-tryckJansson, Daniel, Borg, Mikael January 2001 (has links)
The print- and mailroom at Gefle Dagblad (GD-tyck) is handling an increasing amount of commercial jobsalong with the newspaper production. Investments have above all been done in the mailroom to be able tooffer commercial costumers a higher degree of finishing and there are plans to expand further in the commercialmarket. GD-tryck is of the opinion that they need to secure the quality of their production to be ableto do such expansion, which is the reason why a quality system of some kind may be appropriate. Howeverthere are no plans to certify such a quality system according to ISO 9001:2000.In this exam report the present methods of working have been analysed from a quality perspective.Suggestions on how GD-tryck should be working with quality development is presented in the fields whereshortage of quality has been discovered. The suggestions taken together do not form a quality system butcan be looked at as ideas of approach to quality fields that have to be developed if a working quality systemshall be accomplished.Many of the quality fields that have been discussed do not have anything to do with technical qualitydirectly but are in some degree requirements for a working quality system. It also feels urgent to illustratethese fields in this exam report when most people at GD seems to place quality as identical with technicalquality. Technical quality is also a quality field where GD-tryck has few concrete problems today and theyalready produce printed matters of a high quality. Afact that might make it difficult to adopt a quality systemas the benefits of such a system is not obvious.

Granskning av kvalitetssäkringsarbetet vid en ICC-profilbaserad trycksaksproduktionNyberg, Astrid, Baars, Kristina January 2001 (has links)
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.

ICC-profilers funktionalitet vid byte av tryckfärgskvalitetLiljeroth, Katarina January 2004 (has links)
This degree theme work aims to evaluate the present ICC-profile and printing ink of Dalarnas Tidningar AB. The companyhas changed printing ink quality and wants to evaluate how the present ICC-profile work with the new printingink. Four different ICC-profiles were included in the comparison.One test printing was accomplished with two different separations. Two new ICC-profile was created, as a comparingmaterial. An densitometer was used to measure the technical parameters of the printing. IT8-charts and RGB-chartswas measured with spectrophotometer. La*b*-values, CMYK-values, graybalance curves, color deflections and colorgamuts was compared on screen and on the printed material.Materials from an earlier testprinting and evalution, made by Stora Enso Kvarnsveden AB 2003, was used to evaluatethe function of Dalarnas Tidningar AB´s ICC-profile with the present printing ink quality. The IT8-chart from todaystestprinting was oppened in a program for textediting to have access to La*b*- and CMYK values. The values from theearlier testprinting was supplied from Stora Enso Kvarnsveden AB.The result of this work shows that the ICC-profile from the company, compared with de other profiles, reproduce darkershadow regions which can make loss of details. An higher saturation is recieved in the red and yellow area while thegreen and blue area lose its intensity. The profile gave images which are some contrastless and with a flat reproduction.Today printing ink quality gives more saturation and intensity in the yellow and blue area compared with former printingink. The dark tone reproduces with decreased luminance, however.

Framtagning av ICC-profil för VTAB BackaBjurell, Malin, Amnéus, Katarina January 2003 (has links)
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.

Provtryck på skärmNaseri, Masoud January 2001 (has links)
This Degree Project is carried through in association with Fototext in Guthenburg. The firmsees benefits using”Soft Proof” technology for both economic and time-saving. The reasonfor ”Soft Proofing” for internal/ external production is to estimate and controll documentswithout using digital or chemical printing output.The different technical solutions to ”Soft Proof”, knowledges and facts aboutColorManagement together with PDF-workflow is going to pattern for a correct succesfull”Soft Proofing” on the monitor.Acrobat 5 in association with Photoshop 6 are effectively used in ”Soft Proofing” technic.The advance and capacity of the graphical softwares which are explained in this reporthelps the users to begin to experiment with ”Soft Proof”. Graphical firms which are interestedto begin working with ”Soft Proof” need to allready have knowledge in ICC-profilingand a practical ColorManaged workflow.

Färgstyrning av Kodak Nexpress på Digital Printing NetworkMöller, Jesper January 2009 (has links)
Det här examensarbetet berör ämnet färgstyrning inom digitaltryck. Grundprincipen medfärgstyrning är att få hela den grafiska produktionskedjan att resultera i en förutsägbar och korrektslutprodukt. Den här styrningen sker i huvudsak med hjälp av ICC-profiler.Syftet med arbetet var att hjälpa företaget dpn att ta fram ett väl fungerande arbetsflöde för derastvå Kodak digitalpressar. Företaget ville dels få en så bra färgmatchning mellan de bådatryckpressarna som möjligt, och dels få en så bra matchning mot gällande standardvärden föroffsettryck som möjligt. Dessutom syftade arbetet till att utveckla min egen kunskap kring arbetetmed färgstyrning.Arbetet utfördes genom instudering av relevant teori i ämnet, vilken sedan applicerades på detpraktiska arbetet. Det praktiska arbetet bestod främst i att trycka testkartor som mättes upp och lågtill grund för skapande av ICC-profiler.Arbetet visade sig ge ett positivt resultat. Mätningar gjordes dels innan arbetet påbörjades för attkontrollera hur stor färgavvikelsen var vid det tillfället. Efter skapande och applicering av de nyaprofilerna visade sig färgavvikelsen ha minskat, både sinsemellan de båda tryckpressarna och motgällande standard. Avvikelsen hamnade under de målvärden företaget satt upp på förhand, menlämnade samtidigt utrymme för ytterligare förbättringar på sina ställen.SlutsatserRapporten visar att målsättningen att få de båda tryckpressarna på företaget att trycka med enfärgavvikelse under de på förhand uppsatta värdena kunde uppnås med god marginal. Vidarekonstaterades också att målet att få de båda tryckpressarna att simulera mot standardvärden föroffsettryck kunde uppnås, med undantag för några enstaka färgvärden. / Color management of Kodak Nexpress on Digital Printing NetworkThis thesis concerns the subject of color management in digital printing. The basic principle ofcolor management is to get the entire graphic production to result in a predictable and accurate endproduct. This control is mainly made by the use of ICC profiles.The purpose of this work was to help the company dpn to produce a well-functioning workflow fortheir two Kodak digital presses. The company wanted to get as good color matching between thetwo printing machines as possible, and get a good match with the existing standard values for offsetprinting as possible.The work was carried out by studying of relevant theory on the subject, which then was applied tothe practical work. The practical work consisted mainly of printing test charts, which was measuredand was the basis for the creation of the ICC profiles.The work proved to give a positive result. Measurements were made before the work began tocontrol how much color difference was at the time. After the creation and application of the newprofiles it was shown that color deviation have declined, both between the two printing presses andwith the current standard. Deviation fell below the targets the company had set up in advance, butdid allow for further improvements in their places.ConclusionsThe report shows that the objective of the two Kodak Nexpress to print with a color differenceunder the pre-determined values could be achieved with good margin. Moreover, it was found thatthe objective of the two Kodak Nexpress to simulate the default values for offset printing wasachieved, with the exception of a few color values.
